CONNECTING COPPER TUBES
To connect the copper tubes, follow the procedures below:
NOTE:
When removing the flare nut stopper from the inside unit, confirm “Ping”, sounds because the mixed gas is charged in
the inside unit,
3. Once a smooth match is made, tighten the flare nut
using a wrench. Be very careful not to strip the
threads or flare nut. Repeat this process for the small
and large tubing. When tightening the flare nut, use
another wrench to securely hold the coupler from
twisting and possibly damaging the tubing.
4. Remove the flare nut stoppers from the outdoor unit’s
valves. Connect the larger copper tubing to the larger
valve on the outdoor unit. Connect the smaller copper
tubing to the smaller valve on the outdoor unit.
5. Perform a leak test on all copper tube connections. To
prevent heat loss and damage to walls from condensation, the copper tube connections coming from the
wall must be insulated. Do this by wrapping foam rubber or equivalent around the connection approximately 8mm thick so no copper tubing is exposed.
NOTES:
• As with all wiring and hookups on this unit, make sure
the AC plug on the 12K indoor unit is unplugged.
• Be very careful not to strip the threads or flare nut.
• When insulating the connections, use foam rubber or
equivalent.
1. Connect the drain hose extension to the drain hose
coming from the indoor unit by loosing the clamp on
the extension using a phillips screwdriver, attaching
the hoses together and then tightening the clamp.
2. Run the drain hose, slanted downward, outside. If the
drain pipe is exposed
indoors, make sure it is
thoroughly insulated so
condensation does not
ruin walls or furniture or
come in contact with the
AC connection or extension. Also, do not crease
or form a trap in the tubing.

AIR PURGING
After operating the 9K and the 12K indoor units at the same time,
execute air purging or refrigerant charging.
Air and moisture remaining in the refrigerant system may create
adverse conditions as indicated below:
Before Air Purging
After connecting the power
supply, open the solenoid
valve by pressing the install
switch on the control
panel before air purging
or refrigerant charging.
• pressure in the system rises.
• operating current rises.
• cooling efficiency drops.
• moisture in the refrigerant circuit may freeze and block capil-
lary 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 evacuated to remove moisture from the system.
After air puring or refrigerant charging, turn the install switch off.
AIR PURGING WITH VA CUUM PUMP (TEST R UN)
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 avail
-
able, 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.

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:
2. 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.
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.
3. Loosen the charge hose connected to the wide tube service port slightly to release the pressure, then remove the
hose.
4. 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.
5. 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..

CAUTION:
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.
4. 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.
5. 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.
31
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 (execute the pump down of the 12K and 9K respectively)
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 0.5 kg/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.
