1 INDOOR UNIT INSTALLATION
1.1 Installation of Duct Type
1.1.1 Before Installation
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.
1.1.2 Installation Site
Ensure the top hanging piece has strong strength to withstand the weight of the unit.
The drainage pipe has convenient flow of water.
There is no obstacle blocking the return air inlet and exhaust outlet, so as to ensure sound air circulation.
The installation spaces required by the drawing must be ensured, so as to provide enough space for the service and
maintenance.
The installation site must be far away from heat source, leakage of inflammable gas or smoke.
The indoor unit is of ceiling mount (indoor unit is hidden inside the ceiling).
The indoor and outdoor units, the power cable and the connecting electrical lines must be at least 1 meter from any TV set or
radio. This is to avoid image interference or noise of the TV set or radio. (Even if the distance is 1 meter, noise can also exist if
there is strong electric wave.)
1.1.3 Caution for Installation
Generally, the unit is installed indoor on ceiling. For ceiling mounting, ensure that the hangers on ceiling have adequate
strength to support the weight of the unit.
To meet the noise and vibration requirements, the unit shall be installed by using rubber pad (thickness ≥20mm
(13/16inch)) and rubber connector.
Insert a M10 expansion bolt into the hole. Drive a nail into the bolt. Refer to the profile dimensions drawing of the indoor unit
for the distance between the holes. Refer to Figure 3-1-1 for the installation of the expansion bolt.
