Do not operate circulator without sufficient liquid
in the reservoir or severe damage could occur.
Do not overflow circulator. Allow for addition of
product.
Connecting Electrical Power
The unit requires an electrical connection that must be properly grounded. The power
cord of this circulator is equipped with a grounded plug which mates with a standard
grounded wall outlet. Operate the unit using only the power cord that has been
supplied when purchased. Leakage current of this unit can exceed 3.5mA.
Electrical power required is:
2050-1
115V, 60Hz, 10A
2050-4
230V, 50/60Hz, 5A
Filling the circulator
Be sure the drain plug is properly installed before filling with fluid. Fill the circulator with
water, propylene glycol or other non-flammable appropriate thermal fluid. Circulator
should be filled approximately 0.5” from top or until the low liquid level alarm shuts off.
Additional fluid may be needed after the unit is turned on to compensate for external
tubing volume.
Operation of the unit in temperature ranges near or below 0ºC may cause the fluid to
attract water into the reservoir, especially in areas of high ambient humidity. Overtime,
this can cause the reservoir to overflow.
To prevent severe burns, keep all extremities away from the fluid in the reservoir tank
or any exterior surfaces around the tank.
Emptying the circulator
Before draining the circulator, be sure the unit is at room temperature. To empty the
circulator, remove the 1/8” MPT plug (unscrew by turning counter-clockwise) located on
the lower left side of the circulator.
Be sure fluid is at room temperature before draining.
Contact with hot fluid can cause severe burns
