Move it from side to side, up and down to ensure the unit
is hooked securely.
Piping and wrapping
Evenly bundle the tubing, connecting cable and drain hose
securely with tape as shown in Figure 12.
Because the condensed water from the rear of the indoor unit
gathers in the drain pan and is piped out of the room, do not
put anything else in the drain pan.
Do not allow piping to hold indoor unit away
from the wall.
Never intertwine power wiring and other wiring.
Outdoor Unit Installation
Outdoor Installation precautions
• Install the outdoor unit on a rigid base to prevent noise
level and vibration.
• Place the outdoor unit in such a manner to minimize
restriction of discharge air.
Protect the unit from prevailing winds. To ensure the
unit operates correctly, place the unit lengthwise along
a wall or use a dust or shield plate.
Figure 13A
• If a wall mount installation is required, the installation
bracket should meet the requirement in the installation
bracket diagram and the wall should be able to support
the installation.
Figure13B
Figure 12
IMPORTANT NOTES:
• Indoor unit must be connected before the outdoor unit.
• Drain hose should not be allowed to become slack.
• Insulate both the auxiliary pipings.
• Ensure that the drain hose is positioned at the lowest
side of the bundled tubing. Positioning it at the upper
side can cause the drain pan to overflow inside the unit.
• Drain hose should be sloped downward to ensure condensate will drain correctly.
• Be sure there are no obstacles blocking air discharge.
The installation wall should be constructed of brick, concrete or another surface of equal strength to hold the
unit safely. Make sure the connections to the wall,
bracket and unit are firmly seated and there are no obstructions to the airflow.
Anchoring the outdoor unit
The unit should be tightly anchored, horizontally, with a nut
and bolt ( 10 or 8) on a concrete or similarly rigid, stable
surface.

Leak Testing (Nitrogen or Nitrogen-Traced)
Pressure test the system, using dry nitrogen and soapy water
to locate any leaks in the system. If you wish to use a leak
detector, charge the system to 10 psi using the appropriate
refrigerant, then use nitrogen to finish charging the system to
working pressure. Apply the detector to suspect areas. If
leaks are found, repair them. After repair, repeat the pressure
test. If no leaks exist, proceed to System Evacuation.
System Evacuation
Condensing unit liquid and suction valves are closed to contain
the charge within the unit. The unit is shipped with the valve
stems closed and caps installed. Do not open valves until
the system is evacuated.
1. Connect the vacuum pump with 250 micron capability to
the service valves.
2. Evacuate the system to 250 microns or less using suc-
tion AND liquid service valves. Using both valves is nec-
essary as some compressor create a mechanical seal
separating the sides of the system.
3. Close the pump valve and hold vacuum for 10 minutes.
Typically, pressure will rise during this period.
NOTES:
• If the pressure rises to 1000 microns or less and remains steady, the system is considered leak-free; proceed to start-up.
• If pressure rises above 1000 microns but hold steady
below 2000 microns, moisture and/or non-condensables
may be present or the system may have a small leak.
Return to step 2. If the same result is encountered,
check for leaks as previously indicated and repair as
necessary, then repeat evacuation.
• If pressure rises above 2000 microns, a leak is present.
Check for leaks as previous indicated and repair as necessary then repeat evacuation.
5. Maintain the starting voltage at more than 90% of the
rated voltage marked on the name plate.
6. Confirm the wire gauge is as specified in the power source
specification.
7. Always install an earth leakage circuit breaker in a wet or
moist area.
8. A drop in voltage may be caused by the vibration of a
magnetic switch, causing damage to the contact point,
fuse breakage, disturbance of the normal function of the
overload.

• When relocating the unit to another place, perform the
evacuation using a vacuum pump.
• Refrigerant added to the unit must be in liquid form. (Does
not apply to units using R-22.)
Use caution when handling the packed valve:
• Open the valve stem unit it comes in contact against the
stopper. Do not attempt to open further.
Safe Refrigerant Handling
While these items will not cover every conceivable situation,
they should serve as a useful guide.
WARNING
Refrigerants are hea vier than air. They can "push out"
the oxygen in your lungs or in any enclosed space.To
avoid possible difficulty in breathing or death:
•
Never purge refrigerant into an enclosed room or
space. By law, all refrigerants must be reclaimed.
•
If an indoor leak is suspected, throughly ventilate the
area b efor e begi nning work.
• Liquid refrigerant can be very cold. To avoid possible
frostbite or blindness, avoid contact and wear gloves
and goggles. If liquid refrigerant does contact your
skin or eyes, seek medical help immediately.
• Always follow EPA regulations. Never burn refrig erant, as poisonous gas will be produced.
WARNING
To avoid possible e x plosion:
•
Never apply flame or steam to a refrigerant cylinder.
If you must heat a cylinder for faster charging,
partially immerse it in wa rm water.
•
Never fill a cylinder more than 80% full of liquid re frigerant.
• Never add anything other than R-22 to an R-22 cy linder or R-410A to an R-410A cylinder. The service
equipment used must be listed or certified for the
type of refrigerant used.
• Store cylinders in a cool, dry place. Never use a cy linder as a platform or a roller.

• Securely tighten the valve stem cap with a spanner or
similar tool.
• See tightening torque table in Tightening Connection
section.
Safety Check
After completing the electrical installation:
1. Grounding: After grounding the unit, measure the grounding resistance by visually inspecting the unit and by using a grounding resistance tester, making sure the grounding resistance is less than 4.0 ohms.
2. Electrical leakage check (to be performed during operation): During the test operation after complete installation
of the unit, the qualified installer may use the electroprobe
and multimeter to perform the electrical leakage check.
Turn off the unit immediately if leakage occurs.
WARNING
To avoid possible explosion, use only returnable (not
disposable) service cylinders when removing refrigerant from a system.
• Ensure the cylinder is free of damage which could
lead to a leak or explosion.
• Ensure the hydrostatic test date does not excee d
5 years.
• Ensure the pressure rating meets or exceeds 400
lbs.
When in doubt, do not us e cylinder.
