contact your dealer.
1. If Issues Persist
If the issues continue even after checking the following, contact your dealer and have the following
information ready:
(1) Unit Model Name
(2) Description of the Issue
2. No Operation
Check whether the SET TEMP is set to the desired temperature.
3. Not Cooling or Heating Properly
●Check for obstruction of air flow at the outdoor or indoor units.
●Check if there are too many heating sources in the room.
●Check if the air filter is clogged with dust or other obstructions.
●Check if doors or windows are open.
●Check if the ambient temperature conditions are within the operation range.
4. The Following Are Not Abnormal:
●Odor from Indoor Unit
Unpleasant odor diffuses from indoor unit after a long period of time. Clean the air filter and panels and
ensure that there is sufficient ventilation.
●Sounds from Moving Parts
When starting or stopping the system, a sound might be made. However, this is likely due to thermal
deformation of plastic parts. If so, it is not abnormal.
●Steam from Outdoor Heat Exchanger
During the defrosting operation, ice on the outdoor heat exchanger melts, resulting in steam.
●Dew on Air Panel
When the cooling operation operates for an extended period of time under high humidity conditions, dew can
form on the air panel.
●Refrigerant Flow Sound
While the system is starting or stopping, the sound of refrigerant flowing may be heard.
Filter Cleaning (Filter Not Factory-Installed)
Please replace or clean the filter regularly, as dust can gradually accumulate onto the surface of the filter
after a long period of time.
Follow these steps to properly replace the filter:
After removing the two manual bolts, take down the filter
cover and pull out the filter from the case, then insert the
new one into the case along the filter rail. Finish by fixing
the filter cover with manual bolts.

Installation and Maintenance
1. Safety Notice and Tips
WARNING
• Install the air conditioner on a solid base that can support the unit's weight. (An inadequate base or incomplete
installation may cause injury, due to falling off from the base.)
•Electrical work should be carried out in accordance with the installation manual and the local and national
electrical wiring rules or codes.
(Insufficient capacity or incomplete electrical work may cause electrical shock or fire.)
• Be sure to use a dedicated power circuit. (Never use a power supply shared by another appliance.)
• For wiring, use a cable long enough for the entire distance, and do not use an extension cord.
• Do not put other loads on the power supply, and ensure a dedicated power circuit is used.
• Use the specified types of wires for electrical connections between the indoor and outdoor units. (Firmly clamp
the interconnecting wires so that the terminals receive no external stress.)
• Incomplete connections or clamping may cause terminal overheating or fire.
• After establishing connection between all the wires, secure the cables to prevent undue force on the electrical
covers or panels. (Install covers over the wires. Incomplete cover installation may cause terminal overheating,
electrical shock, or fire.)
• There is 100PSIG of high pressure nitrogen in the evaporator, that must be released it first before installation.
It indicates that the evaporator is sealed if nitrogen escapes, otherwise, it can indicate an evaporator leak.
• When installing or relocating the system, be sure to keep the refrigerant circuit free from air (Air in the
refrigerant circuit may cause an abnormal pressure rise or rupture, resulting in injury or damage.
• If any refrigerant leakage occurs during the installation work, ventilate the room liberally.
• After all installation is completed, ensure that no refrigerant leaks. (The refrigerant can produce toxic gas if
exposed to flames.)
• When carrying out piping connections, do not allow air substances other than the specified refrigerant to enter
the refrigeration cycle, else it can cause decreased performance, abnormally high pressure in the refrigeration
cycle, explosion, and injury.)
• Ensure that the installation has a proper ground-earth connection. Do not ground the unit to a utility pipe,
arrester, or telephone grounding. Incomplete grounding may cause electrical shock. (A high surge current from
lightning or other sources may cause damage to the air conditioner.)
• An earth leakage circuit breaker may be required depending on the site condition, to prevent electrical shock.
• Disconnect the power supply before wiring, piping, or checking the unit.
2. Installation of the Indoor Unit

Installation and Maintenance
NOTE:
These appliances are designed for indoor
installation only.
The indoor units can be installed in one of the
upright, horizontal left, or horizontal right
orientations as shown in the Figures below.
Minor field modifications are necessary to
convert to horizontal left.
2.2 Installation Location
2.3 Installation
2.3a: Upflow Installation
Before selecting the installation site, obtain all required
permissions and follow the below parameters:
·Optimal air distribution is ensured.
·The air path is not blocked or obstructed.
·Condensation is able to drain properly.
·Ensure sufficient clearance for future maintenance and servicing.
·Piping between the indoor and outdoor units should be within the
allowable limits. (Refer to the installation of the outdoor unit
manual)
·The indoor unit, outdoor unit, power supply wiring, and
transmission wiring should be kept at least 3 feet away from
televisions and radio, which prevents image interference and
noise in those electrical appliances.(Noise may be generated
depending on the conditions under which the electric wave is
generated, even if this distance is maintained.)
·Do not install the indoor unit in a machinery shop or kitchen
where vapors from oils or any mists can reach the indoor unit.
Any oils will collect on the heat exchanger, thereby reducing the
performance of the indoor unit, and may deform, and in the
worst case, break the plastic parts of the indoor unit.
·When the unit is installed in a hot and humid place, it is
recommended to insulate the cabinet exterior and to use
auxiliary drain pans.
·If installed above a finished living space, an auxiliary drain
pan(as required by many building codes) must be installed under
the entire unit, and its condensate drain line must be routed to a
location such that the user will see the condensate discharge.

The upright installation method is selected by default.
When the unit is horizontal-right mounted, rotate it to
the right by 90 degrees, as shown in the image for
horizontal-right installation (2.3b).
When the unit is horizontally-left mounted (2.3c), the
following steps are required.
1). Disassemble the lower panel and the sealed plate.
2). Disassemble the retaining clips for the evaporator
so that the evaporator can be pulled out along the
lead rail easily.
3). Rotate the evaporator by 180 degrees and insert it
into the upper side of the lead rail.
4). Rotate the unit to the left by 90 degrees, as shown
in the image "2.3b: Horizontal-Left Installation".
5). Reinstall the sealed plate and the lower panel.
2.4 Air Duct
Field duct work must comply with the National Fire
Protection Association NFPA 90NFPA 90B, and any
applicable local ordinances.
Do not, under any circumstances, connect return duct
work to any other heat producing device such as a
fireplace insert, stove, etc. Unauthorized use of such
devices may result in fire, carbon monoxide poisoning,
explosion, personal injury or property damage.
