Chapter 2 Instruction For Pre-installation
CRV+ air cooled AC unit is a professional equipment which involves complex installation works. This chapter details
the installation preparation, including how to prepare the installation environment and space and reserve the
maintenance space, and how to unpack and inspect. Please read this chapter carefully before installation.
2.1 Equipment Room Consideration
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.
Note
Do not use the indoor unit for outdoor environment.
2.2 Space Clearance For Maintenance
The CRV+ air cooled AC unit is a set of full-featured steam compressor refrigerating air-cooled unit. It is
recommended to be installed in a row of cabinets with high heat density and 'hot aisle & cold aisle' arrangement.
