INSTALLATION
1. Determine the type of wall (sheetrock, concrete, etc.)
and make sure it is strong enough to hold indoor unit.
Select an approximate position for the unit, taking the
required distances away from walls/AC outlet into
consideration.
INDOOR UNIT
• Do not install the unit in an area with direct sunlight, near
heat sources (radiator, etc.), or an area where leakage of
flammable gas may be expected.
• Select a position in the room, high on the wall, where the
whole room can be uniformly cooled.
• Select a location that can hold the weight of the unit and
where the copper tubing, drain hose and Indoor to Outdoor
Wire have the shortest distance to the Outdoor unit.
• Make sure the Indoor unit is installed at least 10cm (3.95in)
away from the top and left side wall and at least 30cm
(11.8in) from AC outlet and right side wall.
OUTDOOR UNIT
• Do not install the unit in an area near heat sources,
exhaust fans, or an area where leakage of flammable gas
may be expected.
• Do not install the unit in a humid, damp or uneven location.
• Select a location that is well ventilated .
• Leave enough room around the unit for air intake, exhaust
and possible maintenance.
2. Determine if the hole is to be made at the left or right
hole location.
3. Using drill with hole-cutting attachment or equivalent, cut
a hole 70mm (2.75") in diameter. The hole should be
made at a slight downward slant to the outdoor side.
Measure the thickness from the inside to outside edges
and cut a PVC pipe at a slight angle 1/4" shorter than the
thickness of the wall and insert pipe in wall.
4. For sheetrock, wooden or similar wall, measure down
from the ceiling using a level or tape measure and attach
the wall bracket to the wall using 4 screws. If you are not
able to line up the holes with the beams, use toggle
bolts. Make sure the wall bracket is even and flush
against the wall.
Indoor Outdoor
Cut at slight angle
CAUTION
• Before making hole, make sure there are no studs, pipes,
electrical wiring or conduit directly behind the area to be cut.
For Concrete, or similar type wall, make holes into the wall and insert concrete nails instead of screws.
INST ALLING THE INSTALLATION PLATE
To install the wall bracket, follow the procedures below. One hole is required for the tubing and may be either on the left or right side.

CAUTION:
• When using the tube reamer, hold the tube downward and make sure no copper scraps fall into the tubing.
2. Make a flare at the end of the copper tube with a flare
tool.
Make sure the inside surface and edges are smooth
and the sides are uniform length.
1. Cut the copper tube extension to the desired length
with a tube cutter. It is highly recommended that 1 foot
is added to the requested length. After cutting, deburring may be necessary (see below diagram). Perform
this with a tube reamer.
BEFORE AFTER
PREPARING THE COPPER TUBING (NOT INCLUDED)
A copper tubing extension (not included) may need to be cut. If this is the case, it will also have to be deburred and
flared as shown below:

1. Remove the flare nut stoppers from the inside unit.
Determine the location of the copper tubing and
where the bends will be. Gently bend the copper tubing, making sure to use big angles so no crimping will
occur. Try to do this on the first try as repeated bending may break or crimp the tubing.
2. Remove the plastic stoppers from the tubing. Connect
the large and small copper tubing to the respective
extension and rotate the flare nut with your finger until
a smooth match is made. Make sure the copper
extension has foam rubber (insulation) on it.
Flare Nutcoupler
CONNECTING THE 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 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
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
AIR PURGING WITH VACUUM PUMP (TEST RUN)
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
(Save for reuse.)
CA UTION:
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.
CA UTION:
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.

the system.
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.
1. With the service valves on the outdoor unit remaining closed, remove the
threaded cover on the wide tube service port.
2. Attach a manifold valve (with pressure gauge) and dry nitro gen gas cylinder
to this service port with charge hoses.
11
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.
CA UTION:
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..
