Side panel cutout locations & dimensions
If piping and wiring from the base are difficult, connection from the side panel can be selected. The locations and
dimensions of the knock-out holes are shown in Figure 2-20. You can select the in and out holes according to the
actual needs, but must confirm that any two of the pipe, power cable and signal cable cannot use the same hole.

2.4 Installing Indoor Unit
2.4.1 Equipment Room Requirement
The requirements of the equipment room are as follows:
1. Damp proof and heat preservation work must be well done to make sure that the environment control system in the
air conditioner room can operate normally.
2. The equipment room should have good heat insulation and sealed damp proof layer. The damp proof layer of the
ceiling and walls must use polyethylene film, and the coating of the concrete wall and the floor must be damp proof.
3. The outdoor air that enters the equipment room should be reduced to a minimum, better below 5% of the total
indoor airflow, as it may increase the load of heating, cooling, humidifying and dehumidification of the system.
4. All the doors and windows should be closed and the openings should be as narrow as possible.
2.4.2 Installation Space
Note
The air conditioner can generate condensate, which may be leakage due to the incorrect installation or use. Do not install it in the
vicinity of any precision equipment so as to maintain the normal operation, and the installation site must provide drain pipes.
1. To ensure normal operation, adequate installation space for the indoor unit must be provided.
2. Avoid locating the indoor unit in confined areas, which can baffle the airflow, shorten the cooling cycle and result in
down-draft and air noise.
3. Avoid locating the indoor unit in a concave or at the end of a long and narrow room.
4. Avoid locating multiple indoor units close to each other. That can result in crossing air patterns, unbalanced load and
competitive operation.
5. For the convenience of daily maintenance, do not install other devices (such as smoke detector) over the cabinet.
