After receiving the machine, please check for any transport damage. If finding any surface or
internal damage, please immediately report to the transport company or equipment company in writing.
After receiving the machine, please check the unit and accessories in reference to the packing list.
Ensure that the model is correct and the machine is in good condition. Please also check if the
specification and quantity of accessory parts are correct.
Determine the correct handling route and methods, thus to avoid damaging the unit or causing
possible hazard. For the sake of protection and safety, it is suggested to move the unit with the
packaging box. Even though it is not permitted to do like this under special occasions, do not remove the
packaging box, thus to avoid loosening or falling during handling.
Confirm if the installing foundation is solid. When this unit is to be installed on the metal section of
the building, make sure that the electrical insulation must comply with applicable standards.
Ensure that the place of installation is far from the area where the inflammable or explosive
substances are stored, thus to avoid possible explosion or fire due to leakage.
1.3.2 Installation Site
Select an installation site where the following conditions are fulfilled and that meets your customer's
approval.
(1) Obstruct should be put away from the intake or outlet vent of the indoor unit so that the airflow
can be blown through all the room.
(2) Make sure that the installation meets the requirement of the schematic diagram of installation
spaces.
(3) Select the place where can stand 4 times of the weight of the indoor unit and would not increase
the operating noise and vibration.

Note: There will be large amount of greasy dirt accumulated on the fan, heat exchanger and water
pump located in the dinning room and kitchen, which would reduce the capacity of the heater exchanger,
lead to leakage and abnormal operation of the water pump.
