• Ensure that all Local, National and International regulations are satisfied.

• Read this “PRECA UTIONS FOR SAFETY” carefully before Installation.

• The precautions described below include the important items regarding safety. Observe them without fail.

• After the installation work, perform a trial operation to check for any problem. Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.

• Turn off the main power supply switch (or breaker) before the unit maintenance.

• Ask the customer to keep the Installation Manual together with the Owner’s Manual.

• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DE-

The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its pressure is approx. 1.6 times higher than that of refrigerant R22. Accompanied with the ne w refrigerant, refrigerating oil has also been changed. Therefore , during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does not enter the refrigerating cycle.

To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of the main unit and installation tools are charged from those for the conventional refrigerant.

Accordingly the exclusive tools are required for the new refrigerant (R410A). For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust

does not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance force and impurity in it.

EVACUATING

Air Purge

This air conditioner can be installed up to the connecting pipe length and height difference in the following table.

Capacity rank

SM56 type SM80 type

With respect to the preservation of terrestrial environment, adopt “Vacuum pump” for air purge (Evacuate air in the connecting pipes) when installing the unit.

• Do not discharge the refrigerant gas to the atmosphere to preserve the terrestrial environment.

• Use a vacuum pump to discharge the air (nitrogen, etc.) remained in the set. If the air remains, the capacity may decrease.

For the vacuum pump, be sure to use one with backflow preventer so that the oil in the pump does not backflow into the pipe of the air conditioner when the pump stops. (If oil in the vacuum pump is put in an air conditioner including R410A, it may cause trouble on the refrigeration cycle .)

Check and Test Operation

For R410A, use the leak detector exclusively manufactured for HFC refrigerant (R410A, R134a, etc.).

* The conv entional leak detector for HCFC refrigerant

(R22, etc.) cannot be used because its sensitivity for HFC refrigerant lowers to approx. 1/40.

• Pressure of R410A is approx. 1.6 times higher than that of R22. If installation work is incompletely finished, a gas leakage may

occur when pressure rises during operation. Therefore, be sure to test the piping connections for leakage.

• Check gas leakage at the flare nut connections, valve stem cap connections and service port cap fittings with a leak detector or soap water .

CAUTION

When the remote controller is used for the first time, it accepts an operation approx. 5 minutes after the power supply has been turned on.

It is not a trouble, b ut is because the setup of the remote controller is being checked. For the second pow er-ON time and after, approx. 1 minute is required to start the operation by the remote

controller.

Installation/Servicing Tools

In the case of an air conditioner using R410A, in order to prevent any other refr igerant from being charged accidentally, service por t diameter of the outdoor unit control valve (3 way valve) has been changed. (1/2 UNF 20 threads per inch)

• In order to increase the pressure resisting strength of the refrigerant piping flare processing diameter and size of opposite side of flare nuts has been changed. (for copper pipes with nominal dimensions 1/2 and 5/8)

Changes

As pressure is high, it is impossible to measure by means of conventional gauge. In order to prevent any other refrigerant from being charged, each port diameter is changed.

In order to increase pressure resisting strength, hose materials and port size are changed (to 1/2 UNF 20 threads per inch). When purchasing a charge hose, be sure to check the port size.

As pressure is high and gasification speed is fast, it is difficult to read the indicated value by means of charging cylinder, as air bubbles occur.

The sizes of opposite sides of flare nuts have been increased. Incidentally, a common wrench is used for nominal diameters 1/4 and 3/8.

By increasing the clamp bar’s receiving hole, strength of spring in the tool has been improved.

Used when flare is made with using conventional flare tool. Connected to the conventional vacuum pump. It is necessary to use an

adapter to prevent vacuum pump oil from flowing back to the charge hose. The charge hose connecting part has two ports - one for conventional refrigerant (7/16 UNF 20 threads per inch) and the other for R410A. If the vacuum pump oil (mineral) mixes with R410A, sludge may occur and damage the equipment.

Exclusive for HFC refrigerant.

FINAL INSTALLATION CHECKS

Check and Test Operation

For R410A, use the leak detector e xclusiv ely manufactured for HFC refrigerant (R410A, R134a, etc.). The conventional leak detector for HCFC refrigerant (R22, etc.) cannot be used because its sensitivity for HFC

refrigerant lowers to approx. 1/40.

• Pressure of R410A is approx. 1.6 times higher than that of R22.

If installation work is incompletely finished, a gas leakage may occur when pressure rises during operation. Therefore, be sure to test the piping connections for leakage.

• Check gas leakage at the flare nut connections, valve stem cap connections and service port cap fittings with a

leak detector or soap water.

CAUTION

When the remote controller is used for the first time, it accepts an operation approx. 5 minutes after the power supply has been turned on.

It is not a trouble, b ut is because the setup of the remote controller is being checked. For the second pow er-ON time and after, approx. 1 mun ute is required to start the operation by the remote controller .

Useful Functions

In addition to the code checking by remote controller of the indoor unit, troub les of the outdoor unit can be diagnosed by LED indications on the cycle control P.C. board of the outdoor unit. Utilize them for various chec ks. For the check by remote controller of the indoor unit, refer to the Installation Manual of the indoor unit. Before a check, confirm each bit of the DIP switch SW801 is set to OFF position.

Recovery method of refrigerant

• When recovering refrigerant in case of reinstallation of the indoor or outdoor unit, etc., use the refrigerant recov-

ery switch SW802 on the cycle control P.C. board of the outdoor unit.

Work procedure

1. T urn on the power supply.

2. Using the remote controller, set F AN operation to the indoor unit.

3. Pushing the refrigerant recovery switch SW802 on the cycle control P.C. board of the outdoor unit starts the forced cooling operation. (Max. 10 minutes), and then the refrigerant is recovered by operation of the valve.

4. After recovery of the refrigerant, push the refrigerant recovery switch SW802 together with closing the valve . The operation stops.

5. T u rn off the power supply.

Installation/Servicing Tools

• In order to increase the pressure resisting strength of the refrigerant piping flare processing diameter and size of

opposite side of flare nuts has been changed. (for copper pipes with nominal dimensions 1/2 and 5/8)

Changes

As pressure is high, it is impossible to measure by means of conventional gauge. In order to prevent any other refrigerant from being charged, each port diameter is changed.

In order to increase pressure resisting strength, hose materials and port size are changed (to 1/2 UNF 20 threads per inch). When purchasing a charge hose, be sure to check the port size.

As pressure is high and gasification speed is fast, it is difficult to read the indicated value by means of charging cylinder, as air bubbles occur.

The size of opposite sides of flare nuts have been increased. Incidentally, a common wrench is used for nominal diameters 1/4 and 3/8.

By increasing the clamp bar’s receiving hole, strength of spring in the tool has been improved.

Used when flare is made with using conventional flare tool. Connected to the conventional vacuum pump. It is necessary to use an

adapter to prevent vacuum pump oil from flowing back to the charge hose. The charge hose connecting part has two por ts-one for conventional refrigerant (7/16 UNF 20 threads per inch) and one for R410A. If the vacuum pump oil (mineral) mixes with R410A a sludge may occur and damage the equipment.

Exclusive for HFC refrigerant.

• Incidentally, the “refrigerant cylinder” comes with the refrigerant designation (R410A) and protector coating in the

U,S.’s ARI specified rose color (ARI color code: PMS 507).

• Also, the “charge port and packing for refrigerant cylinder” require 1/2 UNF 20 threads per inch corresponding to the

charge hose’s port size.
