HIGH TEMPERATURE LIMIT SWITCH

RECALIBRATION

If the temperature in the heater exceeds 210ºF (99ºC), the high temperature limit will shut off the power. The switches must be manually reset by pushing the red buttons. The limit switch has been calibrated at the factory and should not require adjusting. If the calibration changes and must be re-adjusted, the procedure is as follows:

Models 4-18kW

Hold lock nut (F) and turn calibrating screw (G) clockwise 1/8 turn to increase set point 7ºF (3.9ºC), or hold screw (G) and turn nut (F) clockwise.

Model 24 - 58kW

Turn adjustable screw (D) clockwise to raise set point - 1/8 turn equals about 7ºF (3.9ºC).

REMOVAL

1.Shut off power and drain tank; remove leads from terminals (E).

2.Remove two screws holding the switch on the bracket.

3.Loosen nut (A), then remove bushing (B) from tank. The high limit switch and sensor bulb (C) can now be removed from tank.

INSTALLATION

1.Pull end of sensor bulb (C) into recess in bushing (B).

2.Insert bushing (B) and sensor bulb into tank; holding

sensor bulb in place with capillary tube, tighten bushing (B).

3.Lock sensor bulb and capillary tube in place by tightening nut (A).

CAUTION !!

Do not overtighten nut, or sleeve inside of bushing will cut through tubing.

4.Replace switch on bracket. Replace leads on terminals.

CAUTION !!

Be sure tank is filled with water before turning on power.
