Site Preparation
The refrigeration unit should be installed in an environment that meets the following conditions:
• Indoors
• Above ground
• Well ventilated area. Room size must meet minimum requirements of ASHRAE-15 and
EN-378. See Installing a Refrigeration Unit to Meet ASHRAE Requirements on page 4-3.
• Room temperature of 4-38° C (40-100° F)
• Relative humidity of 20-80%, non-condensing
The Polycold Cryochiller must remain vertical while operating. The refrigeration unit is not gravity sen-
sitive and may be placed at any elevation relative to the cryosurface.
Access
During operation, the Polycold Cryochiller
requires 51mm (2 inches) of clear area at
the back of the system and 914mm (36
inches) at the front.
See Figure 3-2.
This clearance is required for access to
switches, settings, air circulation, and
safety reasons.
For service and maintenance, it is recom-
mended that the unit is installed with as
much clear service access as the facility
will allow.
Routine service is performed from the
front.
Major compressor service requires a mini-
mum of 36 inches of rear clearance.
Units that are seismic anchored require a
minimum of 914mm (36 inches) of rear
service access.
Units that have the caster option require
51 mm (2 inches) of side clearance for
gripping the unit.
Multiple units may be placed side by side
as long as the rear clearance is provided.
Multiple units placed facing each other
require 914mm (36 inches) front service
access.
