LOCATION REQUIREMENTS SOUND CONSIDERATIONS
•
Refer to G&D data sheet for sound data
Locate the unit away from sound-sensitive areas
•
Chilled fluid piping should not be supported by chiller frame
•
•
Seal all wall penetrations
Note: Consult an acoustical engineer for critical applications.
FOUNDATION
Provide a concrete foundation of sufficient strength and mass to support the applicable operating weight (i.e.,
including completed piping, and full operating charges of refrigerant, oil and water). G&D Data sheet for unit
operating weights. Once in place, the unit must be level within 1/4" (6.4 mm) over its length and width as well as
anchored to the surface. Construct a concrete pad fully supporting the footprint of the chiller. Mount the unit directly
to the concrete pads. Level the unit using the base rail as a reference. The unit must be level within 1/4" over the
entire length. Chiller must be in contact with the concrete pad around its complete perimeter. G&D Chillers is not
responsible for equipment problems resulting from an improperly designed or constructed foundation.
