To protect your application, the adjustable High Temperature/Low Liquid
Level Safety (HIGH TEMP/LOW LEVEL) ensures the heater will not exceed
temperatures which can cause serious damage to your unit. A single tem-
perature sensor, located on the heater coils in the bath, monitors both
conditions. A High Temperature/Low Liquid Level fault occurs when the
temperature of the sensor exceeds the set temperature limit.
In the event of a fault, the unit will shut down. The cause of the fault must be
identified and corrected before the unit can be restarted.
The safety is not pre-set and must be adjusted during initial installation.
To set the safety, locate the HIGH TEMP/LOW LEVEL SAFETY adjustment dial
on the right side of the pump box. Turn the dial fully clockwise and press the red
RESET switch. The RESET switch is located next to the adjustment dial. On
units without reset, cycle the unit's power switch.
Start the unit. Adjust the setpoint for a few degrees higher than the highest
desired fluid temperature and allow the bath to stabilize at the temperature
setpoint. Turn the HIGH TEMP/LOW LEVEL SAFETY dial counter-clockwise
until you hear a click and the unit shuts down. The red FAULT LED on the
temperature controller will light to indicate a fault has occurred.
Cool the bath and then, without moving the adjustment dial, press the red
RESET switch or cycle the power switch.
