● Proper handling of this unit requires two people. Safe handling and installation of the indoor unit requires
the strength of two people. Mounting the unit alone may cause injury due to a 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.
NOTICE
● The optional decorative panel can become deformed if the positioning of the indoor unit's suspension
brackets are not stable or level. Condensation can accumulate in low spots as a result due to escaping
air through any resulting gaps between the indoor unit and the decorative panel.
● Check to ensure that the condensate hose discharges moisture properly. If connected incorrectly, it can
result in leakage and damage to property.
● Make sure to use the factory-supplied condensate hose and hose clamp. Other makes can cause
moisture leakage.
● 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 ceiling or 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 units 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 affect
ceiling or wall surfaces.
● After the drain check is completed, insert the rubber plug again and seal the gap with a silicon sealant.
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
unit 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 conditioner unit.
