yourself. Installation is complex and requires high
level of training and very specific tools.
Performance, safety, and longevity levels fully
depend on the quality of the installation.
Do not allow children play with or operate the
system without adult supervision.
Please remember, indoor fan runs continually in
cooling mode, while the compressor cycles on or
off as needed to maintain the set temperature. This
is normal and required for proper sampling of the
room air temperature across the temperature
sensors located in the indoor section. Power
consumed by the indoor unit is totally insignificant
and should not cause any economical concerns.
Owner performed maintenance should be limited
to washing the indoor unit’s air filters and hosing
off the outdoor unit’s heat exchanger regularly. Any
other maintenance and deeper cleaning should be
performed by trained personnel only.
Always disconnect power to the entire system by
turning off the main breaker before cleaning or
maintenance.

assuring the units inside were not damaged during
transportion. All packing materials are recyclable.
Do not discard the system components or packing
improperly to avoid environmental pollution.
Do not use the system for any purpose other then
air conditioning and heating the space it is installed
within.
Operate and regularly maintain the system as
instructed in this manual. Since not all possible
conditions and situations can be properly outlined
in this manual, as with any electrical appliance,
use common sense and caution during operation
and maintenance. Do not attempt to repair this
appliance without hiring a qualified technician.
Do not use the air conditioner without the air filters
properly installed and regularly cleaned, at least
once every 2 weeks or more often as needed.
Ignoring this important factor will cause expensive
repairs and cleaning to the heat exchangers.
External surfaces of the indoor and outdoor units
can be cleaned by warm water and mild soap, while
power is disconnected. Do not drip water inside.
Warranty is valid only when the equipment is
installed properly by licensed HVAC contractors

INSTALLATION INSTRUCTIONS - Indoor Unit Installation
PIPE HOLE DRILLING
• One 3” diameter hole, to accommodate the refrigerant
lines, drain tubing and interconnecting cabling to pass
through is usually drilled behind the indoor unit, based
on the exact location of the connector pipes on the back
side of the indoor unit. Please use careful judgement to
locate the location of the hole in relation to the mounting
plate, based on the location of the connection pipes.
• Insert the accessory plastic wall sleeve through the
hole to assure a smooth surface.
Positive downward
inclination (3~4%)
Right Exit
Rear Exit
Left Exit
CONNECTING REFRIGERANT LINES
• Refrigerant pipes can be attached to the indoor unit
from 3 different directions. Most common location is by
approaching from across the rear, in a perpendicular
angle. Where this is not possible, the pipes can be
entered from either the left or the right side panel of the
indoor unit by removing the knockouts on panels.
• If the a rear approach routing is used, swing out the
connector pipes of the indoor unit to obtain a
perpendicular angle, while supporting the part of the
connector pipes attached to the unit, to avoid causing
internal cracks at the heat exchanger’s header.
• Keep the plastic caps on until ready to make your
connections to avoid contamination.
• Uncoil the refrigerant lines as shown in the drawing
by rolling on a flat surface, not by pulling apart. Use
extreme care not to cause any kinks and collapses on
the copper pipes that will restrict the refrigerant flow
and cause deficiencies. Avoid sharp bends.
• If the copper pipes are bent or shaped too many
times, they will become stiff and brittle.
• Be extremely gentle when bending the copper tube
set to avoid kinks and collapses.
• Attach the copper line set to the indoor unit’s
connector pipes, using double (backup) wrenches, and
using the correct torque to avoid the likelihood of leaks.
• Bundle all pipes, wires and the drain hose together
using the provided wrapping tape. Assure the drainage
hose is located at the lowest / bottom position within
the bundle. Assure not to create any siphons, wrong
inclination angles or pinched areas on the drain line.
• Use the provided sealing putty to seal the pipe hole
entirely to avoid passage of air through.

INSTALLATION INSTRUCTIONS - Outdoor Unit Installation
• Outdoor unit should only be installed outdoors, and on a sturdy slab, or on top of a flat roof,
or on suitable brackets that are mounted to an exterior wall.
• Observe all shown clearance in drawings on all sides from other walls or fixed objects.
• Do not install in narrow or enclosed spaces or frequently flooded areas.
• Use the vibration absorber pads provided with the unit to reduce operational sounds.
• Assure to properly and strongly fix the unit to a solid structural part of the building.
• Different size units have different size feet and mounting hole locations.
• Use the provided drain port and attach a PVC drain pipe to the bottom of the casing only if
the outdoor unit is hung high on a wall and where the water dripping is not desirable (usually
applicable for installation on tall buildings to avoid water dripping on sidewalks). Otherwise
this is not necessary for simpler backyard or rooftop installations.
CONNECTING REFRIGERANT LINES
• Do not remove the plastic covers on the
outdoor units valves and at the end of the line
set, until you are ready to connect them together
to avoid contamination.
• Route to approach the ends of the line set to
the corresponding valves on the outdoor unit, by
shaping the copper lines gently to avoid kinks
and sharp angles.
• Remove the plastic caps on mating ends and
quickly screw the brass flare nuts on the line set
to the corresponding brass valve on the outdoor
unit. Use proper torque to tighten the flare nuts
to prevent any possibility of a refrigerant leakage.
While application of less then required torque can
cause leaky connections, application of
excessive torque can crack the flares on the
copper tubes and just as risky for causing leaks.
Use extreme caution.
• Recommended way is to use an adjustable
torque wrench with the settings provided later.
EVACUATION PROCEDURES
• MOST CRITICAL ASPECT OF THE ENTIRE
INSTALLATION IS THE EVACUATION.
• Air that remains in the line set and the indoor
unit must be entirely evacuated using proper
vacuum pump and charging gauge set.
• Air naturally contains some degree of humidity,
which creates acid when combined with the oil
and other chemicals in the refrigeration system.
Acid, weakens the varnish insulation on the motor
windings on the compressor and cause
premature and irreversible compressor failure.
• The larger (Gas side) service valve is
equipped with a service port. The size of the
service port is SAE 5/16”. Use a gauge set with
5/16” hoses or utilize a port adapter to hook up
the low side gauge hose to the service port.
13
INSTALLATION INSTRUCTIONS - Outdoor Unit Installation
EVACUATION PROCEDURES (cont’d.)
Line set to Indoor Unit
• First remove the brass service port cap and
then hookup the low side (blue) hose of the
charging manifold to the service port.
• Attach the common side (yellow) hose to the
vacuum pump. Turn on the vacuum pump.
• Open the low side valve on the charging
manifold all the way. Notice the changing sound Internal Connections
of the vacuum pump that starts to suck.
• Run the vacuum pump for 30 minutes to obtain
the necessary vacuum levels to evaporate all
moisture trapped in the system and remove the
air entirely. Keep an eye on the low side gauge
to assure the max vacuum is achieved.
• Shut off the low side valve on the charging
gauges to lock the vacuum in. Turn off the
vacuum pump. Keep everything as is for 30
minutes and then check the low side gauge once
more to assure the vacuum is holding up. Even
the slightest increase on the gauge readings
indicate a leak at one of the flare connections.
• After assuring that the vacuum is holding up, remove the hexagonal brass caps on both
service valves of the outdoor unit to expose the valve cores (spindles) located underneath.
• Insert a proper sized Allen wrench into the center cavity of the valve core inside the larger
(gas) valve. Turn counter clockwise for 1/4 turn and wait for 10 second to release a small test
amount of refrigerant into the line set.
• Using soap and water mixture, check all 4 flare nuts you connected carefully for any
refrigerant leaks. Retighten any leaky connections until the leak is completely stopped.
• After assuring that no more leaks exist in any of the pipe connections, open both of the
valves by using proper sized Allen wrenches. Turn them counter clockwise until the valve
cores are back seated fully (use common sense not to force them out beyond that point).
• Using soap and water mixture, once more check all 4 flare connections carefully for any
refrigerant leaks. Retighten any leaky connections until the leak is completely stopped.
• Please remember to leak check the system using the same method, for one last time after
startup and if possible while running HEAT mode (with even higher pressures).
• R410A refrigerant can not be topped off in case of a leak. Even for partial leaks, the entire
remaining refrigerant must be removed and system must be re-evacuated and recharged.
ALTERNATIVE EVACUATION PROCEDURES (Not recommended or Endorsed)
• Some sources mention using an alternative evacuation procedure, called bleeding or
flushing, without properly utilizing a vacuum pump. Manufacturer does not recommend or
endorse using these methods as it is usually illegal to vent refrigerant into the atmosphere.
• With this procedure, a small amount of refrigerant is released into the line set by opening
the gas valve for 1/4 turn for 3-4 seconds and then closing it tight. Following the release of
this small amount of refrigerant, the flare nut on the opposite (liquid) valve is loosened and
the gas pressure is relieved into the air, flushing along some of the trapped air inside.
• Repeating this procedure for 3-4 times, usually removes most of the air trapped inside by
sweeping it across the system. Both valves can then be opened after the loosened flare nut
on the liquid valve is properly retightened. Proper leak checking must follow.
• This procedure is not environmentally friendly and may be illegal. Please do not attempt!

• Wrap the entire line set, using the wrapping tape provided. Secure the line set to the structure
using clamps or an accessory decorative PVC line cover kit (sold separately).
• Seal the exit hole on the wall, from the outside to prevent any air or water from entering.
• After assuring all electrical connections are properly secured, turn the breaker on. Check if
the power light on the indoor unit’s display comes on.
• Start the system. Test for all modes and functions for full operational availability.
• Check for abnormal sounds, vibrations or burning smells for both sections.
• Check the temperature of the supply air from the indoor unit to be approximately 15~20°F
cooler than the room air in cooling and 15~20°F warmer than the room air in heating mode.
• Observe that the outdoor fan is running properly and feel the outdoor unit’s discharge air to
be warmer than the ambient air in cooling and cooler than the ambient in heating mode.
• If the standard accessory line set has been extended or trimmed by more than 5 feet, add
or remove proper amount of refrigerant as indicated in the related table in this manual.
• Check for the pressure reading on the low side gauge attached to the service port. Adjust
the refrigerant amount as necessary for proper operation, using temperature/pressure charts
and superheat method. At 95°F Ambient temperature the suction line pressure should be
between 115~125 PSI and the measured superheat should be between 5-7°F.
• If any freezing is observed on the service valves, this is an indication of low refrigerant.
• Record all required operational technical data on the warranty registration form.
• Have your licensed HVAC contractor fill out, sign and stamp the warranty registration form.

the L and N terminals of both Indoor and outdoor units should be 110~120 VAC.
• For 208~230 Model systems, when the power is connected, the measured voltage between
the L1 and L2 terminals of both Indoor and outdoor units should be 208~230 VAC.
• When the compressor is running, the measured voltage between the 1 and G terminals of
both Indoor and outdoor units should be 110~120 VAC. (G is ground lug in outdoor unit)
• When the outdoor fan is running, the measured voltage between the 2 and G terminals of
both Indoor and outdoor units should be 110~120 VAC. (G is ground lug in outdoor unit)
• When the system is in HEAT mode, the measured voltage between the 3 and G terminals
of both Indoor and outdoor units should be 110~120 VAC. (G is ground lug in outdoor unit)
• Always assure that same color coded wires connect to same numbered terminal positions
at both the Indoor and Outdoor Units’ terminal blocks and none are inverted or crossed.
• In case a component is not energized, check for continuity on the specific cable feeding
that device all across its length. Core of the cable may have been pinched/broken.
• If power properly reaches the indoor unit and the indoor unit does not display any lights,
check for the condition of the fuse located on the indoor unit’s electronic controller card.
• If there is no cooling or heating effect, or the cooling or heating effect is weak, check to
make sure the outdoor units valves are opened fully following a proper vacuuming/evacuation
procedure. Check for the entire length of the piping set for kinks and collapses. Check and
verify the pressure measured at the gas valve’s service port. Check to make sure both service
valves at the outdoor unit are cold (Approx 36~42°F) in cooling mode and hot (Approx 80~110°F)
at heating mode. Assure that the surfaces of the valves, portions of the line set and/or the
indoor unit’s heat exchanger coil are not frozen.
• If there is water dripping from the indoor unit, assure that the drainage hose is properly
routed, not kinked or collapsed, does not have any upward inclination or siphons. Observe
that the condensate water is dripping from the end of the drain hose.
• If the discharge areas of the indoor unit is sweating in cooling mode, assure there are no
open windows or doors that can create high indoor humidity conditions.

REQUIRED MAINTENANCE PROCEDURES
• Periodic maintenance is essential for assuring
the best performance and longevity from this high
quality comfort system.
• Always turn the breaker off before performing
any maintenance on any part of the system.
INDOOR UNIT MAINTENANCE (Biweekly)
• Flip open the front cover, by pulling by both hands
simultaneously, at the notches on either side of the
panel as illustrated with the arrows.
• Lift the bottoms of both air filters out of their clips
and then pull them downward to slide them off of
their railings in the unit.
• Using warm water and mild detergent mixture
(max temp 110°F) wash off all accumulated dust
and use clean water to rinse. Lay them somewhere
indoors to dry naturally.
• Reinsert properly back in the correct position,
assuring they stay within their railings. Insert the
bottom parts in their holding clips.
• Other optional filters may have been installed in
the unit. Optional filters are not washable and must
be replaced once in every 6 months.
• If the heat exchanger under the filter seems to be dusty as well, use a brush with soft
bristles and sweep the dust off, between the aluminum fins. Edges of the fins are sharp. Do
not touch the heat exchanger with bare hands. Do not disturb or bend the fins to block air
flow. A vacuum cleaner my also be used to clean the dust. Assure not to touch any part of the
unit with the vacuum cleaner’s hose. Heat exchanger is a very delicate component.
• If the heat exchanger is too dusty to be easily cleaned, it needs to be professionally cleaned
using special methods and materials. In this case call for service.
• Properly close the front panel, assuring to snap the locking pins back in their mating locks.
OUTDOOR UNIT MAINTENANCE
• (Monthly)
The only required maintenance for the outdoor unit is regular washing.
• Using low pressure water from a garden hose, wash the outdoor unit’s heat exchanger to
remove any dust, salt, sand and other debris. Do not use pressurized water or a pressure
washer as this will damage the delicate fins of the heat exchanger.
• Do not spray water inside the unit through the fan grill.
• Sweep and wash away all accumulated leaves and other debris from surroundings.
• In areas with heavy snow, frequently inspect the unit to assure it is not snowed in or blocked
off at the air inlet and air outlet points (if operational for heating purposes).
• Trim the bushes and other vegetation growth that may interfere with the air flow.
• If the drain hoses are accessible, check for algae clogging, bug nests or other obstacles.
SEASONAL MAINTENANCE (Annually)
• If the system is to be used seasonally, perform the above maintenance procedures at the
end of each season. Then run the system in FAN only mode for 1 hour to dry up the moisture
from the heat exchanger and the drain pan. Finally, turn the power off from the breaker. If
available, a suitable soft cover may be placed on the outdoor unit. However, always remember
to remove the cover before operating the unit again to avoid internal damage.
