Never place the circulator in a location where excessive heat, moisture,
inadequate ventilation, or corrosive materials are present.
Carefully install the circulator to ensure it does not fall into the bath or
that its line cord does not make contact with the bath contents.
All circulators except A45HC can operate with 0 clearance on two exhaust
sides as long as the third exhaust side has unrestricted air flow. A45HC must
have at least 25mm [1"] of clearance on both sides to comply with UL leak
mitigation safety standards. Blocked ventilation increases the circulator's
temperature, reduce its cooling capacity and, on refrigerated baths, eventually
lead to premature compressor failure.
