concerning the location of the installation

plate. Routing of the wiring to power outlets

is through the walls typically. Drilling the

hole through the wall for piping

connections must be done safely.

Drill a Hole in the Wall

- Drill the piping hole with a ø65mm hole core

drill. Drill the piping hole at either the right or

the left with the hole slightly slanted to the

outdoor side.

Flaring Work

Main cause for gas leakage is due to defect of

flaring work. Carry out correct flaring work in

the following procedure.

1 Use the piping kit accessory or the pipes

purchased locally.

2 Measure the distance between the indoor

and the outdoor unit.

3 Cut the pipes a little longer than measured

distance.

rial 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.

ENGLISH

- 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/cm

(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/cm

G) (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 includ-

ing 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 re-

duced 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 deter-

gent on the indoor unit connection or outdoor

unit connections by a soft brush to check for

leakage of the connecting points of the pip-

ing.

- If bubbles come out, the pipes have leakage
