Section III Installation

Site

The refrigeration system requires that the circulator must be located on
a level surface. Never place the circulator in a location where excessive
heat, moisture, or corrosive materials are present.
Locate the circulator in a laboratory or clean industrial environment.

Pollution Degree
Circulators have an air-cooled refrigeration system. Air is drawn through the
front and discharged through side and rear panels. Position the circulator so
the intake and discharge are not impeded. A minimum clearance of 3 feet
(1 meter) on all four sides is necessary for adequate ventilation. Inadequate
ventilation will reduce cooling capacity and, in extreme cases, can cause
compressor failure.
Excessively dusty areas should be avoided and a periodic cleaning schedule
should be instituted (see Section V, Cleaning).
The circulator will retain its full rated capacity in ambient temperatures up to
approximately +75°F (+24°C). Reduce the cooling capacity 1% for every 1°F
above +75°F, up to a maximum ambient temperature of +95°F. In terms of
°C, reduce the cooling capacity 1% for every 0.5°C above +24°C, up to a
maximum ambient temperature of +35°C.
