1. After applying putty, insert the wall Cap at Indoor side and Outdoor side.

INSTALLATION (CONTINUED)

AIR PURGING

Air and moisture remaining in the refrigerant system may create adverse conditions as indicated below:

• pressure in the system rises
• operating current rises
• cooling efficiency drops
- moisture in the refrigerant circuit may freeze and block capillary tubing
• water may lead to corrosion of parts in the refrigerant system

Therefore, the indoor unit and tubing between the indoor and outdoor unit must be leak tested and evacuated to remove any noncondesables and moisture from the system.

AIR PURGING WITH VACUUM PUMP(TEST RUN)

Confirm each tube (narrow and wide tubes) between the indoor and outdoor units has been properly connected and all wiring for the test run has been completed. Remove the valve caps from the wide and narrow service valves on the outdoor unit. Note that both narrow and wide tube service valves on the outdoor unit are kept closed at this stage (shipping position).

Leak Test

1. With the service valves on the outdoor unit remaining closed, remove the threaded cover on the wide tube service port. (Save for reuse.)
2. Attach a manifold valve (with pressure gauge) and dry nitrogen gas cylinder to this service port with charge hoses.

CAUTION:

Be sure to use a manifold valve for air purging. If it is not available, use a stop valve for this purpose. The "Hi" knob of the manifold valve must always be kept closed.
3. Pressurize the system to no more than 150 P.S.I.G. with dry nitrogen gas and close the cylinder valve when the gauge reading reaches 150 P.S.I.G. Next, test for leaks with liquid soap.

CAUTION:

To avoid nitrogen entering the refrigerant system in a liquid state, the top of the nitrogen gas cylinder must be higher than its bottom when you pressurize the system. Usually, the cylinder is used in a vertical standing position.

1. Do a leak test of all joints of the tubing (both indoor and outdoor) and both wide and narrow service valves. Bubbles indicate a leak. Be sure to wipe off the soap with a clean cloth.
2. After the system is found to be free of leaks, relieve the nitrogen pressure by loosening the charge hose connector at the nitrogen cylinder. When the system pressure is reduced to normal, disconnect the hose from the cylinder.

INSTALLATION (CONTINUED)

Evacuation

1. Attach the charge hose end described in the leak test area to a vacuum pump to evacuate the tubing and indoor unit. Confirm the "Lo" knob of the manifold valve is open. Then, run the vacuum pump. The operation time for evacuation varies with the tubing length and capacity of the pump. The following table shows the amount of time for evacuation:

Required time for evacuation when 30 gal/h vacuum pump is used
If tubing length is less than 33 ft. (10 m)	If tubing length is longer than 33 ft. (10 m)
10 min. or more	15 min. or more

1. When the desired vacuum is reached, close the "Lo" knob of the manifold valve and stop the vacuum pump.

Finishing the job

1. With a hex wrench, turn the narrow tube service valve stem counter-clockwise to fully open the valve.
2. Turn the wide tube service valve stem counter-clockwise to fully open the valve.

CAUTION:

To avoid gas from leaking when removing the charge hose, make sure the wide tube service valve is fully open and turned all the way out.

1. Loosen the charge hose connected to the wide tube service port slightly to release the pressure, then remove the hose.
2. Replace the threaded cover on the wide tube service port and fasten it securely. This process is very important to prevent gas from leaking from the system.
3. Replace the valve caps at both wide and narrow service valves and fasten them securely.

This completes air purging with a vacuum pump. The air conditioner is now ready to test run.

INSTALLATION (CONTINUED)

TEST RUN

Check that all tubing and wiring have been completed correctly. Check again that the wide and narrow tube service valves are fully opened. Turn on the power and run the system.

Service Valve Construction

- Valve Position Closed

The valve systems of both the wide and narrow tubes are turned all the way in. The unit is shipped from the factory in this position and it is also used for Pump Down and Air Purging.

• Valve Position Fully Open

The valve stems of both the wide and narrow tubes are turned all the way out. This is normal operating and Test Run position.

• Valve Position Half Open

With the narrow tube valve stem is turned to the halfway-down position. This position is used for pressure measurement and gas charging.

CAUTION:

When opening or closing the service valve stem, be sure to use a hex wrench.

PUMP DOWN

Pump Down means collecting all refrigerant in the outdoor unit without loss in refrigerant gas.

This is performed when the unit is to be relocated or the refrigerant circuit is serviced.

CAUTION:

Be sure to perform Pump Down procedure with the unit cooling mode.

Pump Down Procedure

1. Connect a low-pressure gauge manifold hose to the charge port on the wide tube service valve.
2. Open the wide tube service valve halfway and purge the air from the manifold hose using the refrigerant gas.
3. Close the narrow tube service valve (all the way in).
4. Turn on the unit's operating switch and start the cooling operation.
5. When the low-pressure gauge reading becomes 1 to 0.5kg/cm² (14.2 to 7.1 psi), fully close the wide tube valve stem and then quickly turn off the unit. At that time, Pump Down has been completed and all refrigerant gas will have been collected in the outdoor unit.
