Safety First – This unit should be installed by trained and authorized personnel only. Be certain unit is grounded and installation meets all local electrical codes.


The thermostat is pre-set at approximately 45°. However sometimes during shipment or handling, the setting may become altered and must be reset. CAUTION: One complete turn of the adjusting screw on the thermostat changes the temperature setting by 80°. Several turns on the adjusting screw may ruin the thermostat and void any warranty. Turn the adjusting screw counterclockwise (as if removing a screw) to raise the temperature setting; turn clockwise to lower temperature setting. Temperature range of thermostat is 0° to 175° F.
In the event thermostat sticks or fails to function, which can occur after several years in service or after a period of non-use, turn adjusting screw 1/4 turn each way a few times. In many instances, this will activate the points and thermostat will function properly. If after this procedure the thermostat still doesn’t work, it will have to be replaced. IMPORTANT: Before replacing thermostat, check your heating element by following TEMPORARY EMERGENCY MEASURE INSTRUCTIONS.
If thermostat fails during freezing weather, water can be kept from freezing by wiring direct.
CAUTION: Thermostat is screwed into 1/2” P.V.C. coupling and should be turned only a little more than hand tight.
