Unit Installation
The chiller must be installed by qualified company or personnel, which is authorized by McQuay, and the
installation must satisfy all the following requirements.
Location
In order to achieve maximum capacity, the location selection should fulfill the following requirements:
1) The location must be well ventilated, so that air can be drawn in and discharge out efficiently.
2) Install the unit in such a way that the hot air discharge cannot be drawn in again by itself or other
units.
3) Ensure that there is no obstruction to airflow into or out of the unit. Remove obstacles which blocking
intake or discharge the air if exist.
4) If good ventilation cannot be guaranteed when unit being installed indoors, it is advisable to induce
discharge air from air outlet to outdoors by installing duct which is as short as possible.
5) Support unit base up to create a space above foundation for ensuring free water drainage, and the
stable foundation with level surface must be sufficiently durable against the unit weight.
6) The location must not be susceptible to dust or oil to avoid condenser coil being choked by the
contaminant. As the general safety precaution, it is advised that no flammable danger gas should be
located near to the unit.
