l
Do not step or put any material on the product.
l
Do not put any foreign material on the unit or inside the unit.
l
Do not turn OFF the main power source of the indoor unit during the season of heating and cooling.
The water can not be discharged forcedly so that overows from the drain pan.
As the result, the oor and the ceiling surface are smudged.
l
Hold the air lter and the air inlet grille by hand when attaching (removing).
If not, it may cause falling or injury.
l
Do not blow cold air to a person for a long time or overcool.
It may cause deterioration of physical condition and health impairment.
l
Do not handle the unit by one person. Although the unit may be packed by polypropylene band, do not
use it for transportation. If the unit is handled by hand, the n surface of heat exchanger causes a cut.
l
Do not install the indoor unit, outdoor unit, remote control switch and cable within approximately 3 meters
from strong electromagnetic wave radiators such as medical equipments.
l
Supply electrical power to the system to energize the oil heater for 12 hours before startup after a long
shutdown.
l
Make sure that the outdoor unit is not covered with snow or ice, before operation.
l
In some cases, the packaged air conditioner may not be operated normally under the following cases.
* In case that electrical power for the packaged air conditioner is supplied from the same power
transformer as the device*.
* In case that the power source wires for the device* and the packaged air conditioner are located close to
each other.
Device*: (Ex) Lift, container crane, rectier for electric railway, inverter power device, arc furnace,
electric furnace, large-sized induction motor and large-sized switch.
It consumes a large quantity of electrical power.
Regarding the cases mentioned above, surge voltage may be inducted in the power supply wiring for the
packaged air conditioner due to a rapid change in power consumption of the device and an activation of
switch.
Therefore, check the eld regulations and standards before performing electrical work in order to protect
the power supply for the packaged air conditioner.
l
Do not install the unit in the place where the air ow directly catches to animals or plants.
It could be the cause of adverse affect to animals or plants.
l
Do not create an upper-slope or rise for the drain piping since drain water can ow back to the indoor unit
and leakage into the room will occur.
l
Do not apply excessive force to the are nut when tightening. If it is applied, the are nut may crack due
to aged degradation and refrigerant leakage may occur. Use the specied tightening torque.
l
It is recommended that the room will be ventilated every 3 to 4 hours.
l
The heating capacity of the heat pump unit is decreased according to the outdoor air temperature.
Therefore, it is recommended that auxiliary heating equipment be used in the eld when the units is
installed in a low temperature region.
