● Proper handling of this unit requires two-people. Safe handling and installing the indoor unit requires the
strength of two people. Mounting the unit alone may cause injury due to fall of the unit. Although the unit
may be girded with steel banding, do not use it for transportation. Avoid contact with finned surfaces of
the heat exchanger as sharp edges can cause severe injury to hands and fingers. Use appropriate work
gloves for the job.
● Check to ensure that the condensate hose discharges moisture properly. If connected incorrectly, it can
result in leakage and damage to furniture.
● Do not bend or twist the factory-supplied condensate hose. This could compromise the seal and result in
moisture leakage.
● Do not apply an excessive force to the condensate pipe connection. This can also compromise the seal
properties of the connection.
● Verify that the installed unit is level with floor and ceiling surfaces. Any variance or inclination can cause
moisture to back up into the condensate pan, overflow, and seepage onto wall surfaces, and cause
damage to carpeted surfaces or furniture below.
● Do not install this system in close proximity to septic sewer lines where flammable and toxic gases can coalesce.
● Inspect the condensate pan before the onset of winter to drain away all accumulated moisture in the pan.
● The heat exchanger of indoor unit overheats whenever there is a slight amount of refrigerant circulating
during slowdown or stoppage. As a result, moisture in the condensate pan evaporates where it can
condense on ceiling or wall surfaces.
● When a wireless controller is used, put a distance of at least 3.3ft (1m) between the indoor unit and
electric lighting. If not, the receiver part of the unit may be difficult to receive operation commands due to
effect of the electric lighting.
Electrical Installation
In some cases, the packaged air conditioner may not be operated normally under the following cases:
● When electrical power for the packaged air conditioner is supplied from the same power transformer
as the external equipment.
● When the power supply wiring for the external equipment and the packaged air conditioner are
located close to each other.
Regarding that mentioned above, surge voltage may be inducted into the power supply wiring for the crated
air conditioner due to a spike in power consumption for this device and an activation of the switch. Check
the field regulations and standards before performing any electrical work in order to safeguard the power
supply for the crated air conditioning unit.
