SELECTION

OF LOCATION

This unit, both indoor and outdoor, is suitable for installation in a commercial and light industrial environment. If installed as a household appliance it could cause electromagnetic interference, in which case the may be required to take adequate measures. ■

Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small animals.

■

Small animals making with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the area around the unit clean.

When installing the unit in a small room, take measures in order to keep the refrigerant concentration from exceeding allowable safety limits in the event of a refrigerant leak. Excessive refrigerant concentrations in a closed room can lead to oxygen deficiency.

Obtain the customer's permission before installing. The inverter units should be installed in a location that meets the following requirements: 1

The foundation is strong enough to the weight of the unit and the floor is flat to prevent vibration and noise generation. If not, the unit may fall over and cause damage or injury.

In places with weak reception, keep distances of 3 m or more to avoid electromagnetic disturbance of other equipment and use conduit tubes for power and transmission lines. ■

In heavy snowfall areas, select an installation site where snow will not affect the operation of the unit.

■

The refrigerant R410A itself is nontoxic, nonflammable and is safe. If the refrigerant should leak however, its concentration may exceed the allowable limit depending on room size. Due to this, it could be necessary to take measures against leakage. Refer to the chapter "14. Caution for refrigerant leaks" on page 29.

■

AND HANDLING THE UNIT

1

6

■

INSPECTING

Do not install in the following locations. • Locations where sulfurous acids and other corrosive gases may be present in the atmosphere. Copper piping and soldered ts may corrode, causing refrigerant to leak. • Locations where a mineral oil mist, spray or vapour may be present in the atmosphere. Plastic parts may deteriorate and fall off or causing water leakage. • Locations where equipment that produces electromagnetic waves is found. The electromagnetic waves may cause the control system to malfunction, preventing normal operation. • Locations where flammable gases may leak, where thinner, gasoline, and other volatile substances are handled, or where carbon dust and other incendiary substances are found in the atmosphere. Leaked gas may accumulate around the unit, causing an explosion.

4

Lift the unit preferably with a crane and 2 belts of at least 8 m long. (See figure 4) Always use protectors to prevent belt damage and pay attention to the position of the unit's centre of gravity. Use a belt sling of ≤20 mm wide that adequately bears the weight of the unit.

NOTE

5

If a forklift is to be used, preferably transport the unit with pallet first, then the forklift arms through the large rectangular openings on the bottom of the unit. (See figure 5)

5.1 From the moment you use a forklift to move the unit to its final position, lift the unit under the pallet. 5.2 Once at final position, unpack the unit and the forklift arms through the large rectangular openings on the bottom of the unit. Use filler cloth on the forklift arms to prevent damaging the unit. If the paint on the bottom frame peels off, the anti corrosion effect may decrease.

Do not insert fingers, rods or other objects into the air inlet or outlet. When the fan is rotating at high speed, it will cause injury.

Use R410A to add refrigerant. All field piping must be installed by a licensed refrigeration technician and must comply with relevant local and national regulations. Caution to be taken when brazing refrigerant piping Do not use flux when brazing copper-to-copper refrigerant piping. (Particularly for the HFC refrigerant piping) Therefore, use the phosphor copper brazing filler metal (BCuP) which does not require flux.

When installed in a corrosive environment, use a nut with plastic washer (1) to protect the nut tightening part from rust.

Flux has extremely harmful influence on refrigerant piping systems. For instance, if the chlorine based flux is used, it will cause pipe corrosion or, in particular, if the flux contains fluorine, it will damage the refrigerant oil.

1

Be sure to perform a nitrogen blow when brazing. Brazing without performing nitrogen replacement or releasing nitrogen into the piping will create large quantities of oxidized film on the inside of the pipes, adversely affecting valves and compressors in the refrigerating system and preventing normal operation.

Method for removing transportation stays (only for RXYHQ12 units) The 4 yellow transportation stays installed over the compressor legs for protecting the unit during transport must be removed. Proceed as shown in figure 30 and described below. A

Tighten the fixing nut (B) again. CAUTION If the unit is operated with the transportation stays still in place, abnormal vibration or noise may be generated.

PIPING

After completing the installation work, check that the refrigerant gas does not leak. Toxic gas may be produced if the refrigerant gas leaks into the room and comes in with a source of fire. Ventilate the area immediately in the event of a leak. In the event of a leak, do not touch the leaked refrigerant directly. Frostbite may be caused.

6.1.

Installation tools

Make sure to use installation tools (gauge manifold charge hose, etc.) that are exclusively used for R410A installations to withstand the pressure and to prevent foreign materials (e.g. mineral oils such as SUNISO and moisture) from mixing into the system. (The screw specifications differ for R410A and R407C.) Use a 2-stage vacuum pump with a non-return valve which can evacuate to –100.7 kPa (5 Torr, –755 mm Hg). NOTE

6.2.

Make sure the pump oil does not flow oppositely into the system while the pump is not working.

Selection of piping material

1.

Foreign materials inside pipes (including oils for fabrication) must be 30 mg/10 m or less.

2.

Use the following material specification for refrigerant piping: ■ Size: determine the proper size referring to chapter "6.6. Example of connection" on page 9. ■ Construction material: phosphoric acid deoxidized seamless copper for refrigerant. ■ Temper grade: use piping with temper grade in function of the pipe diameter as listed in the table below.

Precautions when knocking out knock holes

NOTE

Precautions when selecting branch piping When the equivalent pipe length between outdoor and indoor units is 90 m or more, the size of the main pipes (both gas side and liquid side) must be increased. Depending on the length of the piping, the capacity may drop, but even in such a case it is possible to increase the size of the main pipes. Refer to page 10. If the recommended pipe size is not available, stick to the original pipe diameter (which may result in a small capacity decrease). 2

6.3.

Pipe connection

Be sure to perform a nitrogen blow when brazing and to read the paragraph "Caution to be taken when brazing refrigerant piping" on page 5 first. NOTE

The pressure regulator for the nitrogen released when doing the brazing should be set to 0.02 MPa or less. (See figure 10) 1

Be sure to avoid damaging the casing

■

After knocking out the holes, we recommend you remove the burrs and paint the edges and areas around the edges using the repair paint to prevent rusting.

■

When ing electrical wiring through the knock holes, wrap the wiring with protective tape to prevent damage.

Removing the pinched piping When connecting refrigerant piping to the outdoor unit, first remove the pinched piping. Do not vent gases into the atmosphere. Removing of the pinched piping must be carried out according to the following procedure: 1. 2.

Make sure the stop valves are closed. Connect a charge hose to the service ports of all stop valves. Recover the gas from the pinched piping. When all the gas is recovered from the pinched piping, dissolve the brazing using a burner and remove the pinched piping.

3. 4.

Any gas remaining inside the stop valve may blow off the pinched piping, causing damage or injury. See figure 6. 1

■

To prevent entry of any contamination and to prevent insufficient pressure resistance, always use the special tools dedicated for working with R410A refrigerant.

Airtightness test: NOTE

Make sure to use nitrogen gas.

Pressurize the liquid and gas pipes to 4.0 MPa (40 bar) (do not pressurize more than 4.0 MPa (40 bar)). If the pressure does not drop within 24 hours, the system es the test. If the pressure drops, check where the nitrogen leaks from.

■

Vacuum drying: Use a vacuum pump which can evacuate to –100.7 kPa (5 Torr, –755 mm Hg)

1.

Evacuate the system from the liquid and gas pipes by using a vacuum pump for more than 2 hours and bring the system to –100.7 kPa. After keeping the system under that condition for more than 1 hour, check if the vacuum gauge rises or not. If it rises, the system may either contain moisture inside or have leaks.

2.

Following should be executed if there is a possibility of moisture remaining inside the pipe (if piping work is carried out during the raining season or over a long period of time, rainwater may enter the pipe during work). After evacuating the system for 2 hours, pressurize the system to 0.05 MPa (vacuum break) with nitrogen gas and evacuate the system again using the vacuum pump for 1 hour to –100.7 kPa (vacuum drying). If the system can not be evacuated to –100.7 kPa within 2 hours, repeat the operation of vacuum break and vacuum drying. Then, after leaving the system in vacuum for 1 hour, confirm that the vacuum gauge does not rise.

Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance. This can lead to electric shock or fire. Be sure to install an earth leakage circuit breaker. (Because this unit uses an inverter, install an earth leakage circuit breaker that is capable of handling high harmonics in order to prevent malfunctioning of the earth leakage breaker itself.) Do not operate until refrigerant piping work is completed. (If operated before completion of the piping work, the compressor may break down.) Never remove a thermistor, sensor, etc., when connecting power wiring and transmission wiring. (If operated without thermistor, sensor, etc., the compressor may break down.) The reversed phase protection detector of this product only functions when the product starts up. Consequently, reversed phase detection is not performed during normal operation of the product. The reversed phase protection detector is designed to stop the product in the event of an abnormality when the product is started up. Replace two of the three phases (L1, L2, and L3) during reverse-phase protection circuit operation. If the possibility of reversed phase exists after a momentary blackout and the power goes on and off while the product is operating, attach a reversed phase protection circuit locally. Running the product in reversed phase can break the compressor and other parts. Means for disconnection must be incorporated in the field wiring in accordance with the wiring rules. (An all-pole disconnection switch must be available on the unit.)

The above table indicates power specifications for standard combinations. See "1. Introduction" on page 1. If using anything other than the above combinations in a multiple outdoor unit system, calculate using the following procedure. Calculate the recommended fuse capacity Calculate, by adding the minimum circuit ampere of each used unit (according to the table above), multiply the result by 1.1 and select the next higher recommended fuse capacity. Example Combining the RXYQ30 by using the RXYQ8, RXYQ10, and RXYQ12. Minimum circuit ampere of the RXYQ8 = 18.5 A Minimum circuit ampere of the RXYQ10 = 21.6 A Minimum circuit ampere of the RXYQ12 = 22.7 A Accordingly, the minimum circuit ampere of the RXYQ30=18.5+21.6+22.7= 62.8 A Multiplying the above result by 1.1 (62.8 x 1.1)=69.08 A, so the recommended fuse capacity would be 80 A.

General cautions

■

Up to 3 units can be connected by crossover power source wiring between outdoor units. However, units of smaller capacity must be connected downstream. For details, refer to the technical data.

■

When connecting several units in VRV combination, the power supply of each outdoor unit can also be connected separately. Refer to the field wiring on the engineering data book for further details.

■

Make sure to connect the power source wire to the power source terminal block and to clamp it as shown in figure 21 and described in chapter "8.8. Field line connection: power wiring" on page 17.

■

For conditional connections, refer to the Technical Data.

■

As this unit is equipped with an inverter, installing a phase advancing capacitor not only will deteriorate power factor improvement effect, but also may cause capacitor abnormal heating accident due to high-frequency waves. Therefore, never install a phase advancing capacitor. Keep power imbalance within 2% of the supply rating. • Large imbalance will shorten the life of the smoothing capacitor. • As a protective measure, the product will stop operating and an error indication will be made, when power imbalance exceeds 4% of the supply rating. Follow the "electrical wiring diagram" supplied with the unit when carrying out any electrical wiring. Only proceed with wiring work after all power is shut off. Always ground wires. (In accordance with national regulations of the pertinent country.) Do not connect the ground wire to gas pipes, sewage pipes, lightning rods, or telephone ground wires. This may cause electric shock. • Combustion gas pipes: can explode or catch fire if there is a gas leak. • Sewage pipes: no grounding effect is possible if hard plastic piping is used. • Telephone ground wires and lightning rods: dangerous when struck by lightning due to abnormal rise in electrical potential in the grounding. This unit uses an inverter, and therefore generates noise, which will have to be reduced to avoid interfering with other devices. The outer casing of the product may take on an electrical charge due to leaked electrical current, which will have to be discharged with the grounding. Be sure to install an earth leakage breaker. (One that can handle high-frequency electrical noise.) (This unit uses an inverter, which means that an earth leakage breaker capable of handling high-frequency electrical noise must be used in order to prevent malfunctioning of the earth leakage breaker itself.)

■

■ ■ ■ ■

■

■

■

Earth leakage breakers that are especially designed for protecting ground-faults must be used in conjunction with main switch and fuse for use with wiring.

■

Never connect the power supply in reversed phase. The unit can not operate normally in reversed phase. If you connect in reversed phase, replace two of the three phases.

Installation manual

14

■

This unit has a reverse phase detection circuit. (If it is activated, only operate the unit after correcting the wiring.)

Precautions when knocking out knockout holes ■

To punch a knockout hole, hit on it with a hammer.

■

Power supply wires must be attached securely.

■

■

If the power supply has a missing or wrong N-phase, equipment will break down.

After knocking out the holes, we recommend you paint the edges and areas around the edges using the repair paint to prevent rusting.

■

Make sure that all wiring is secure, the specified wires are used, and no external forces act on the terminal connection or wires.

■

■

Improper connections or installation may result in fire.

■

When wiring the power supply and connecting the remote controller wiring and transmission wiring, position the wires so that the control box lid can be securely fastened. Improper positioning of the control box lid may result in electric shocks, fire, or overheating of the terminals.

When ing electrical wiring through the knockout holes, remove any burrs from the knockout hole edges. Wrap the wiring with protective tape in order to prevent damage to the wires, put the wires through field supplied protective wire conduits at that location, or install suitable field supplied wire nipples or rubber bushings into the knockout holes.

Remote controller Power supply wiring (sheathed cable) (230 V)

■

Use a power wire pipe for the power wiring.

■

Outside the unit, make sure the weak low voltage electric wiring (i.e. for the remote control, between units, etc.) and the high voltage electric wiring do not near each other, keeping them at least 50 mm apart. Proximity may cause electrical interference, malfunctions, and breakage.

■

Be sure to connect the power wiring to the power wiring terminal block and secure it as described under "8.8. Field line connection: power wiring" on page 17.

■

Inter-unit wiring should be secured as described in "8.7. Field line connection: transmission wiring and cool/heat selection" on page 16. • Secure the wiring with the accessory clamps so that it does not touch the piping and no external force can be applied to the terminal. • Make sure the wiring and the electric box lid do not stick up above the structure, and close the cover firmly.

Precautions when laying power wiring

The outdoor unit PC board (A1P) is factory set at "Sequential start available".

■

Do not connect wiring of different thicknesses to the power terminal block. (Slack in the power wiring may cause abnormal heat.)

Setting the cool/heat operation (heat pump unit only)

■

When connecting wiring which is the same thickness, do as shown in the figure below.

■

For wiring, use the designated power wire and connect firmly, then secure to prevent outside pressure being exerted on the terminal board.

■

Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will strip the head and make proper tightening impossible.

■

Over-tightening the terminal screws may break them.

■

See the table below for tightening torque for the terminal screws.

INSULATION

After finishing the leak test and vacuum drying, the piping must be insulated. Take into the following points: ■

Make sure to insulate the connection piping and refrigerant branch kits entirely.

■

Be sure to insulate liquid and gas piping (for all units).

■

Use heat resistant polyethylene foam which can withstand a temperature of 70°C for liquid side piping and polyethylene foam which can withstand a temperature of 120°C for gas side piping.

■

Reinforce the insulation on the refrigerant piping according to the installation environment. Ambient temperature

The outdoor unit is factory charged, but depending on the length of the piping when installed, the outdoor unit may require additional charging. For charging the additional refrigerant follow the procedure as described in this chapter. Refrigerant can not be charged until all field wiring and field piping has been completed. Refrigerant may only be charged after performing the leak test and the vacuum drying. The refrigerant charge of the system must be less than 100 kg. This means that in case the calculated refrigerant charge is equal to or more than 95 kg you must divide your multiple outdoor system into smaller independent systems, each containing less than 95 kg refrigerant charge.

Minimum thickness

Condensation might form on the surface of the insulation. ■

■

If there is a possibility that condensation on the stop valve might drip down into the indoor unit through gaps in the insulation and piping because the outdoor unit is located higher than the indoor unit this must be prevented by sealing up the connections. See figure 9. 1

Be sure to use tools exclusively for R410A to ensure required pressure resistance and to prevent foreign materials from mixing into the system. Charging with an unsuitable substance may cause explosions and accidents, so always make sure that the appropriate refrigerant (R410A) is charged. Refrigerant containers must be opened slowly.

11.3. Stop valve operation procedure ■

■ ■

Do not open the stop valve until all piping and electrical steps of "10. Checking of unit and installation conditions" on page 18 are completed. If the stop valve is left open without turning on the power, it may cause refrigerant to build up in the compressor, leading to insulation degradation. Always use a charge hose for service port connection. After tightening the cap, check that no refrigerant leaks are present.

1.

Remove the cap and turn the valve clockwise with the hexagon wrench.

2.

Securely tighten the valve until the shaft s the main body seal.

3.

Make sure to tighten the cap securely. For the tightening torque, refer to the table above.

11.4. How to check how many units are connected It is possible to find out how many indoor units are active and connected by operating the push-button switch on the printed circuit board (A1P) of the working outdoor unit. In a multiple outdoor unit system, you can find out how many outdoor units are connected to the system by using the same procedure. Make sure that all the indoor units connected to the outdoor unit are active. Follow the 5-step procedure as explained below. ■

11.5. Additional refrigerant charge There are two ways to charge refrigerant. Use the selected method following the described procedure below. ■

■

Adding refrigerant using leak detection function. Refer to "1 Adding refrigerant using leak detection function" on page 20

1

Adding refrigerant without using leak detection function. Refer to "2 Adding refrigerant without using leak detection function" on page 22 Adding refrigerant using the automatic refrigerant charging function is recommended. If refrigerant is added manually, without using the automatic refrigerant charging function, the refrigerant leak detection function can not be used.

Follow the procedures below. ■

When charging a system, charging over permissible quantity can cause liquid hammer.

■

Always use protective gloves and protect your eyes when charging refrigerant.

■

When the refrigerant charging procedure is done or when pausing, close the valve of the refrigerant tank immediately. If the tank is left with the valve open, the amount of refrigerant which is properly charged may get off point. More refrigerant may be charged by any remaining pressure after the unit has stopped.

Adding refrigerant using leak detection function The automatic refrigerant charging has limits as described below. At out of limit, the system can not operate the automatic refrigerant charging. Outdoor temperature

: 0°C DB~43°C DB

Indoor temperature

: 20°C DB~32°C DB

14. CAUTION

FOR REFRIGERANT LEAKS

Introduction The installer and system specialist shall secure safety against leakage according to local regulations or standards. The following standards may be applicable if local regulations are not available. This system uses R410A as refrigerant. R410A itself is an entirely safe non-toxic, non-combustible refrigerant. Nevertheless care must be taken to ensure that air conditioning facilities are installed in a room which is sufficiently large. This assures that the maximum concentration level of refrigerant gas is not exceeded, in the unlikely event of major leak in the system and this in accordance to the local applicable regulations and standards.

Maximum concentration level Check if the additional refrigerant charge has been finished correctly. Recalculate the required amount of refrigerant from the piping length and add an adequate amount of refrigerant.

The maximum charge of refrigerant and the calculation of the maximum concentration of refrigerant is directly related to the humanly occupied space in to which it could leak. The unit of measurement of the concentration is kg/m 3 (the weight in kg of the refrigerant gas in 1 m3 volume of the occupied space).

■

After correcting the abnormality, press the BS3 RETURN button and reset the malfunction code.

Compliance to the local applicable regulations and standards for the maximum allowable concentration level is required.

■

Carry out the test operation again and confirm that the abnormality is properly corrected.

According to the appropriate European Standard, the maximum allowed concentration level of refrigerant to a humanly space for R410A is limited to 0.44 kg/m3.
