In cases where the outdoor unit is installed above the Indoor unit perform the following.

1 Tape the piping and connecting cable from

down to up.

2 Secure the taped piping along the exterior

wall. Form a trap to prevent water entering the room.

3 Fix the piping onto the wall using saddle or

equivalent

Air Purging

The air and moisture remaining in the refrigerant system have undesirable effects as indicated below.

- Pressure in the system rises.

- Operating current rises.

- Cooling(or heating) efficiency drops.

- Moisture in the refrigerant circuit may freeze and block capillary tubing.

- Water may lead to corrosion of parts in the refrigeration system.

Therefore, after evacuating the system, take a leak test for the piping and tubing between the indoor and outdoor unit.

Forming of the Piping

Form the piping by wrapping the connecting portion of the indoor unit with insulation material and secure it with two kinds of vinyl tapes.

- If you want to connect an additional drain hose, the end of the drain outlet should be routed above the ground. Secure the drain hose appropriately.

In cases, where the outdoor unit is installed below the Indoor unit, perform the following.

1 Tape the piping, drain hose and connecting

cable from down to up.

2 Secure the tapped piping along the exterior

wall using saddle or equivalent.

In cases, where the outdoor unit is installed above the Indoor unit, perform the following.

- Preparation

Check that each tube(both liquid and gas side tubes) between the indoor and outdoor units have been properly connected and all wiring for the test run has been completed. Remove the service valve caps from both the gas and the liquid side on the outdoor unit. Note that both the liquid and the gas side service valves on the outdoor unit are kept closed at this stage.

- Leak test

Connect the manifold valve(with pressure gauges) and dry nitrogen gas cylinder to this service port with charge hoses.

Air purging with vacuum pump

CAUTION

Be sure to use a manifold valve for air purging. If it is not available, use a stop valve for this purpose. The knob of the 3-way valve must always be kept close.

- Pressurize the system to maximum 250 P.S.I.G. (17.6 kgf/cm

G) (R-22 model) or 400 P.S.I.G. (28.1 kgf/cm2G) (R-410A model) with dry nitrogen gas and close the cylinder valve when the gauge reading reaches 250 P.S.I.G. (17.6 kgf/cm

G) (R-22 model) or 400 P.S.I.G. (28.1 kgf/cm2G) (R-410A model). Next step is leak test with liquid soap.

CAUTION

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

WARNING

There is a risk of fire and explosion.

Inert gas (nitrogen) should be used when you check plumbing leaks, cleaning or repairs of pipes etc. If you are using combustible gases including oxygen, product may have the risk of fires and explosions.

- Do a leak test of all joints of the tubing(both indoor and outdoor) and both gas and liquid side service valves. Bubbles indicate a leak. Be sure to wipe off the soap with a clean cloth.

- 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.

*The feature can be changed according a type

of model.

- Remove the caps from the 2-way and 3-way valves.

- Remove the service-port cap from the 3-way valve.

- Apply a soap water or a liquid neutral detergent on the indoor unit connection or outdoor unit connections by a soft brush to check for leakage of the connecting points of the piping.

- If bubbles come out, the pipes have leakage

- Connect a low-pressure gauge manifold hose to the charge port on the gas side service valve.

- Open the gas side service valve halfway and purge the air in the manifold hose using the refrigerant.

- Close the liquid side service valve(all the way).

- Turn on the unit's operating switch and start the cooling operation.

- When the low-pressure gauge reading becomes 1 to 0.5kg/cm

G(14.2 to 7.1 P.S.I.G.), fully close the gas side valve and then quickly turn off the unit. Now Pump Down procedure is completed, and all refrigerant is collected into the outdoor unit.

CAUTION

Be sure to perform Pump Down procedure in the cooling mode.
