PREPARING FOR INSTALLATION

2

Make sure the installation area provides:

❒A three-phase power source supplying the correct current for your chiller model. Check the serial tag on the side of the electrical enclosure for the required voltage, phase, frequency, full load amps, disconnect fuse size and minimum wire connection size. Field wiring should be completed by qualified personnel to the planned location for the chiller. All electrical wiring should comply with your region’s electrical codes.

❒A clean, well-ventilated environment.

The room temperature should not exceed 110° F (43° C) with 95% non-condensing humidity and should not fall below 55° F (12° C).

❒Minimum clearance for safe operation and mainte- nance. Nothing should be placed on top of the unit while the unit is operating. All models require a minimum clear- ance of 5 ft. around the perimeter for servicing. Models equipped with fans also require unrestricted outlet air flow.

❒A source of water for cooling on water-cooled units. City, tower or chiller water may be used, as long as the supply pressure is at least 25 psi and not more than 85 psi.

Install plumbing for process and cooling lines.

See the specification tables for the correct line and fitting sizes. Larger line sizes are acceptable as long as they are reduced at the chiller connections. Smaller line sizes are not recommended.
