Location
YORK Chillers are furnished with vibration isolator mounts for basement or ground level
installations. Units can be located on upper floor levels providing the floor is capable of supporting
the total unit operating weight and optional spring isolators are used.
CAUTION
Sufficient clearance to facilitate normal service and maintenance work must be provided all around
and above the unit and particularly space provided at either end to permit cleaning or replacement of
evaporator and condenser tubes, see Clearance. A doorway or other sufficiently large opening properly
located may be used. The chiller should be located in an indoor location where temperatures range
from 40°F to 110°F (4.4°C to 43.3°C).
Motors
The YK open motor is air cooled. Check state, local, and other codes for ventilation requirements.
Foundation
A level floor, mounting pad, or foundation not provided by Johnson Controls, capable of supporting
the operating weight of the unit.
