Test operation and after
installation check
Before testing:
1. Do not turn power on until installation is
completely finished.
2. Electric wiring must be connected
correctly and securely.
3. Open all cut-off valves on the connection
pipes.
4. All impurities and debris such as scraps
and filings must be cleared from the unit.
Test operation method:
1. On models other than GE AIR 116, GE
AIR 121, PRO AIR I109 and PRO AIR I112
a. Remove the surface panel of indoor
unit,
b. Use a screw driver to set the switch on
the right of the unit to RUN.
2. Switch power on and press ON/OFF
button on the remote controller.
3. Press MODE button and check the
operating condition of each of the COOL,
HEAT and FAN modes. The HEAT mode is
not available on models GE AIR 326 and
GE AIR 428.
4. If the remote control cannot be used,
employ the following forced operation:
a. For models GE AIR 116, GE AIR 121,
PRO AIR I109 and PRO AIR I112
- With the unit stopped, remove the
surface panel and switch the unit to
AUTO mode by pressing the button
located on the right.
- The unit will automatically run in
the mode selected by the
microcomputer according to the
surrounding temperature.
- With the unit running, press the
button to turn the unit off.
b. For all other models:
- With the unit stopped, remove the
surface panel and set switch on the
right of the unit to AUTO mode.
- The unit will automatically run in
the mode selected by the
microcomputer according to the
surrounding temperature.
- With the unit running, set the
switch to STOP to turn the unit off.
- Once the tests are completed, set
switch to RUN for normal
operations. If the switch is not set
to RUN, the unit will start
automatically every time it is
connected to the power grid or
after a power cut.

Air purging and leakage test
For models with multiple indoor units, this
procedure must be executed for each indoor
unit. This procedure requires a manifold
valve and a vacuum pump.
1. Make sure the liquid side valve and gas
side valve are set to the closed position
and check pipes are connected properly.
2. Remove service port nut and connect
manifold valve to the service port of the
3-way valve using a charge hose.
3. Connect manifold valve to the vacuum
pump using another charge hose.
4. Fully open handle Lo on the manifold
valve and run the vacuum pump.
5. Loosen the flare nut of the outdoor unit
3-way valve and check that air
penetrates. If air does not penetrate,
check charge hose is firmly connected
to the service port. Tighten the flare nut.
6. Evacuate the circuit for about 15 minutes
with the vacuum pump. Make sure
compound pressure gauge reads minus
760 mm Hg.
7. When evacuation is complete fully close
handle Lo on manifold valve. Then stop
vacuum pump and disconnect it.
8. First open the liquid side valve completely
then 30 seconds after open the gas side
valve fully.
9. Check connections are not leaking using
soapy water or a special leak spray.
Bubbles indicate leak.
Outdoor condensation drainage space
(not applicable to models GE AIR 326 and
GE AIR 428)
When the unit is heating or defrosting, the
wastewater formed in the outdoor unit can
be removed through the drain hose. If the
wastewater cannot be drained properly
from the base plate, the defrosting will be
incomplete and the heating capacity of the
unit could be reduced significantly.
Installation: install the outdoor drain elbow
on the Ø 25 millimeter hole on the base
plate as shown in Fig. 4, and join the drain
hose to the elbow, so that the wastewater
formed in the outdoor unit can be drained to
the appropriate place.
