2.4 Installing Indoor Unit

2.4.1 Equipment Room Requirement

The requirements on 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 or damp proof coating.
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.
