2. INDOOR UNIT INSTALLATION

2.1 Installation of Duct Type

2.1.1 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 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 the best to do this under some special situations, 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.
2.1.2 Installation Site
Ensure the top mounting bracket is strong enough to withstand the weight of the unit.
Ensure condensate pipe has convenient flow of water.
Ensure 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 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
40 inches 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 40 inches, noise can also exist if there is a strong electric wave.)
2.1.3 Caution for Installation
Generally, the unit is installed indoors on a 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 should be installed by using a 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
