Hi-Limit Thermostat Set Point Instructions
This task is to be performed in when replacing the hi-limit thermostat only. This
applies only to the Tempstar HH machine.
-With the power secured to the machine, unhook the yellow/red striped wire from
the regulating thermostat.
-Turning the power back on, allow the unit to sit idle and heat with the door open.
-The expansion of water in the booster tank and associated plumbing will cause
water to come out of the spray arm temporarily. The ideal height for this spray is
between 2” and 4” before the rinse heater shuts off.
-As tester, your duty is to adjust the nut on the Hi-Limit thermostat so that
condition occurs. Once the desired level of heating is achieved, close the door and
run a cycle.
-Secure power to the machine.
-Reconnect the yellow and red striped wire to the regulating thermostat.
-Turn power back on and run a cycle.
-Continue with the final test as per applicable instructions.
-Verify the rinse thermostat is set between 180 and 195F.
-Verify the wash thermostat is set between 155 and 165F.
