LOCATION
Unit is designed for indoor application and must be located
in an area where the surrounding ambient temperatures are
40°F or above. A good rule of thumb is to place units where
ambients are at least 5 degrees above the leaving water
temperature.
Because of the electrical control devices, the units should
not be exposed to the weather. A plastic cover over the

SPACE REQUIREMENTS FOR
The chilled water piping for all units enters and leaves the
cooler from the rear, with the control box side being the front
side of the unit. A clearance of 3 to 4 feet should be pro-
vided for this piping and for replacing the filter-driers, for ser-
vicing the solenoid valves, or for changing the compressors,
should it ever become necessary.
The condenser water piping enters and leaves the shell
from the ends. Work space must be provided in case water
regulating valves are being used and for general servicing.
Clearance should be provided for cleaning condenser tubes
or for removing cooler tubes on one end of the unit as
specified in Table 1. It is also necessary to leave a work area
on the end opposite that used for replacement of a cooler tube.

trol box is supplied as temporary protection during transfer.
A reasonably level and sufficiently strong floor is all that
is required for the SEASONPAK water chiller. If necessary,
additional structural members should be provided to transfer
the weight of the unit to the nearest beams.
NOTE: Unit shipping and operating weights are available
in the physical data table, pages 21 through 23.

PLACING THE UNIT
The small amount of vibration normally encountered with the
SEASONPAK water chiller makes this unit particularly desir-
able for basement or ground floor installations where the unit
can be bolted directly to the floor. The floor construction
should be such that the unit will not affect the building
struc-
ture, or transmit noise and vibration into the structure. See
vibration isolator section for additional mounting information.
NOTE: On the WHR 120D thru
240D,
shipping bolts are
used to secure the compressor rails to the evaporator
brackets. Remove these and discard after unit is mounted and
before unit is started.
VIBRATION ISOLATORS
Rubber-in-shear or spring isolators can be furnished and field
placed under each corner of the package. It is recom-
mended that a rubber-in-shear pad be used as the minimum
isolation on all upper level installations or areas in which
vibra-
tion transmission is a consideration.
Transfer the unit as indicated under “Moving the Unit.” In

all cases, set the unit in place and level with a spirit level.
When spring type isolators are required, install springs run-
ning under the main unit supports. Adjust spring type mount-
ings so that upper housing clears lower housing by at least

A rubber anti-skid pad should be
used under isolators if hold-down bolts are not used.
Vibration eliminators in all water piping connected to the
SEASONPAK water chiller are recommended to avoid strain-
ing the piping and transmitting vibration and noise.
