CAUTION
Regarding the Airflow of the Indoor Unit
The air that is pulled in by the fan (the “return air”) enters the
grille and is passed through the filter. It is then
cooled/dehumidified/heated through the heat exchanger.
The direction of the air output is manipulated up and down by the
motorized louver, and left to right via manually controlled vertical
deflectors. Some models may come with “dual-swing” capability,
which offers both a horizontal and vertical motorized air flow swing.
Controlling the System’s Airflow
1. Pressing the SWING buttons activates the louver.
• Press the Swing button to trigger the horizontal
flaps to swing up and down. Press this button again
to stop swing movement at the current angle.
• Press the Swing button to trigger the vertical
flaps to swing left and right. Press this button again
to stop swing movement at the current angle.
2. If the vertical deflectors (which are located
underneath the flaps) are adjusted manually,
they can be used to fix the airflow in a certain
vertical position before turning the system on.

Full system-rated capacity and efficiency is obtained at the standard rating conditions as developed by
the testing and rating agencies. Deviations from the rating conditions, especially the atmospheric
conditions, will be compensated by the variable speed compressor, within certain limitations.
Heat pump systems function by exchanging energy, in the form of heat, between the indoor air and
the outdoor ambient air (atmospheric). The system’s net cooling or heating capacities and efficiencies
change by atmospheric conditions, as well as the indoor air conditions (such as temperatures and
humidity levels).
Capacity of the system required for a specific area or application must be determined professionally
using detailed calculations, which are based on several internal and external factors.
To further optimize the performance of your unit, be sure to do the following:
• Keep doors and windows closed.
• Limit energy usage by using TIMER ON and TIMER OFF functions.
• Do not block air inlets or outlets.
• Regularly inspect and clean air filters.
In addition to the filters, the interior of the indoor unit itself as well as the inner coil should be
inspected every season. The front panel can be disconnected and removed from the top hinge
where the pegs connect. This will allow for easier inspection of the interior and behind the air
filters. The interior should be cleaned with damp cloth and neutral soaps. Do not use any sort
of aggressive solvents or detergents. Only a soft cloth that is lightly damp should be used.
Periodic Maintenance Is Essential For The System!
Maintaining the air conditioner will ensure that is stays efficient. Before carrying out any sort
of maintenance, always ensure that the power supply to the system is turned off.

Preparing the Refrigerant Piping of the Indoor Unit
The piping “pigtails” pre-attached to the indoor unit can be run in 3 different ways as shown
in the illustration. Decide which type of configuration is most suitable before continuing.
By default it is routed for a left side exit as shown in #1. This method can either use the left
side knockout for a side exit, or a wall hole can be drilled on the left side of the unit’s rear.
Routing it straight through the back of the system (#2) will facillitate the connections to the
copper pipe extensions to be made outside. This is recommended to simplify the process.
#3 is a right side exit, but is not recommended as it involves a 180° bend of the piping, which
increases the risk of kinking or collapsing the lines dramatically. Bend slowly and cautiously.
If a side-exit is chosen, there are knock-out panels on either side of the unit that can be cut
out along the groove to provide a notch for the pipe to exit from. Use a cutter to do this.
For the method chosen, run the piping in the direction of the wall hole. Bind the copper
pipes, drain pipe, and power cables together with tape, with the drain pipe at the bottom so
that water can flow freely. Ensure that the bundle is exiting at a continuous downward pitch.

CAUTION
• Do not remove the cap from the pipe until it is time
to connect it, to avoid dampness or dirt from entering.
• If the pipe is bent/pulled too often, it will become stiff.
Do not bend the pipe more than three times at one
point. Be extremely careful not to kink any piping.
• When extending the coiled copper pipes, straighten
them by unwinding gently, as shown in the picture.

Refrigerant Piping
Step 1: Cut pipes
When preparing refrigerant pipes, take extra care
to cut and flare them properly. This will ensure
efficient operation and minimize the need for
future maintenance.
1. Measure the distance between the indoor and
outdoor units.
2. Using a pipe cutter, cut the pipe a little
longer than the measured distance.
3. Make sure that the pipe is cut at a perfect 90°
angle. Refer below for bad cut examples:
Oblique Rough Warped
90°
DO NOT DEFORM PIPE
WHILE CUTTING
Be extra careful not to damage, kink, or
deform the pipe while cutting. This will
drastically reduce the efficiency and capacity
of the unit and may cause internal damage.
Step 2: Remove any burrs carefully.
Burrs can affect the air-tight seal of refrigerant
piping connection. They must be completely
removed. Follow these steps for proper deburring:
1.
Hold the pipe at a downward angle to
prevent burrs from falling into the pipe.
2.
Using a reamer or deburring tool, remove
all burrs from the cut section of the pipe.

Step 3: Flare pipe ends
Proper flaring is essential to achieve an airtight
seal.
1.
After removing burrs from cut pipe, seal
the ends with PVC tape to prevent foreign
materials from entering the pipe.
2.
Sheath the pipe with insulating material.
3.
Place flare nuts on both ends of pipe. Make
sure they are facing the correct direction,
because they cannot be put on or have
their direction chaged after flaring.

Copper Pipe
4.
Remove PVC tape from ends of pipe when
ready to perform flaring work.
5.
Clamp flare form on the end of the pipe.
The end of the pipe must extend beyond the
edge of the flare form in accordance with the
dimensions shown in the following table:

8.
Remove the flaring tool and flare form, then
inspect the end of the pipe for cracks and
successful, even flaring.
Step 4: Connect pipes
When connecting refrigerant pipes, be careful
not to use excessive torque, or to deform the
piping in any way. One should first connect the
low-pressure pipe, then the high-pressure pipe.
If provided by the supplier, apply leak
guard material on all flared mating surfaces.

Air Evacuation and Bleeding the Circuit
The air and/or humidity left inside the refrigeration circuit can contaminate the refrigerant
and cause abnormal spikes in pressure, leading to eventual compressor malfunction.
Therefore, after having connected the indoor and outdoor units to create a closed system, it is
necessary to bleed the air and humidity out of the circuit through the use of a vacuum pump.
Evacuation should be performed upon initial installation or when the unit is relocated.
Evacuation Instructions
Before using a vacuum pump and manifold gauge,
read their operation manuals to become familiarized
with using them properly.
1) Unscrew and remove the caps from the
2-way and 3-way valves.
2) Unscrew and remove the cap from the
service port.
3)
Connect the blue (low) hose of the
manifold gauge to service port on the
outdoor unit’s 3-way valve (use an
adapter if needed). Ensure that the pin
fully engages the schrader valve.
4) Connect the yellow (middle) hose from the
manifold gauge to the vacuum pump.
5)
Open the low pressure valve of the manifold
gauge. Keep the high pressure valve closed.

6.
Turn on the vacuum pump to evacuate the system.
7.
Run the vacuum for at least 15 minutes, or until the
Compound Meter reads -76cmHG (-100 kPa or -30
inHg).
8.
Close the low pressure side of the manifold gauge,
and turn off the vacuum pump.
9.
Wait for 5 minutes, then verify that there has been
no rise in the vacuum reading.
10.
If there is a rise in the system vacuum, refer to “Gas
Leak Check” section for information on how to check
for leaks. If no change in vacuum reading, unscrew
the cap from the service valve (high pressure valve).
11.
Insert a hexagonal wrench into the service valve (2-way
valve) and open the valve by turning the wrench in a
1/4 counterclockwise turn. Wait and listen for gas to
exit the system, then close the valve after 5 seconds.
12.
Watch the pressure gauge for a few minutes to make
sure that there is no drop in pressure. The Pressure
Gauge should now show higher than the
atmospheric pressure.
13.
Remove the charge hose from the service port.
14.
Using a hexagonal wrench, fully open both the high
pressure and low pressure valves.
15.
Tighten valve caps on all three valves (service port,
high pressure, low pressure) by hand. Tighten further
using a torque wrench if needed.

Note: This may not be required in some locations.
DURING TEST RUN
Check for Electrical Leakage
During the Test Run, use an electroprobe and
and multi-meter to perform a comprehensive
electrical leakage test.
If electrical leakage is detected, turn off the
unit immediately and call a licensed electrician
to find and resolve the cause of the leakage.
Note: This may not be required in some locations.
GAS LEAK CHECKS
There are 2 methods to check for gas leakage:
Soap and Water Method
Leak Detector Method
WARNING – RISK OF
ELECTRIC SHOCK
ALL WIRING MUST COMPLY WITH
LOCAL AND NATIONAL ELECTRICAL
CODES, AND MUST BE INSTALLED BY
A LICENSED ELECTRICIAN.
Using a soft brush, apply soapy water or
liquid detergent to all pipe connection
points on the indoor unit and outdoor unit.
The presence of bubbles indicates a leak.
If using leak detector, refer to the device’s
operation manual for proper usage
instructions.
