2.2 Installation of Floor Ceiling Type

2.2.1 Before Installation
After receiving the unit, 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.
2.2.2 Installation Site
(1) Install the unit at a place strong enough to withstand the weight of the unit.
(2) The air inlet and outlet of the unit should never be clogged so that the airflow can reach every
corner of the room.
(3) Leave service space around the unit as required in Figure 3-1-23.
