Section 5 – Operation
5.1 Circulator Location
Locate the Circulator on a level surface, free from drafts and out of direct sunlight. Do not place it
where there are corrosive fumes, excessive moisture, high room temperatures, or excessive dust is
present.
Refrigerating/Heating Circulators must be a minimum of four inches (102mm) away from walls or
vertical surfaces so air flow around the unit is not restricted.
To help prevent voltage drops, position the Circulator as close as possible to the power distribution
panel and a properly grounded outlet. The use of an extension cord is not recommended.
Warning: These units are equipped with over-temperature protection (Safety Set). A low liquid level
or failure to set the Safety Set and properly immerse the heater may result in heater burnout and triac
failure. While operating, do not allow the heater to contact any potentially flammable materials, such
as plastic racks or sides of plastic tanks, as a fire hazard may result.
