Calibration of the Independent High Limit Safety Thermostat
A.
Allow the unit to run for at least an hour with the temperature set to 42
°
C. This
will allow adequate time for the internal ambient temperature of the NORM-O-
TEMP
®
cabinet to stabilize.
B.
Turn the unit OFF and unplug from the power source. Move both jumpers on the
power supply board to the
Test
position. Plug the unit into the power source
and turn the unit ON.
C.
Locate the Independent High Limit Safety Thermostat adjustment screw
mounted to NORM-O-TEMP
®
unit base through the hole at the rear of unit.
D.
The unit will begin to heat, when the water temperature reaches 46°C ± 0.6°C
(115.0°F ± 1.08°F), turn the adjustment screw counterclockwise until the alarm
activates. If it is necessary to raise the limit, turn the adjustment screw
clockwise.
E.
To cool the water in the unit, drain some as described in Section 5-1.4. and
replenish. Allow the unit to heat up again to make sure the Independent High
Limit Safety Thermostat powers off the heater and the pump at 46°C ± 0.6°C
(115°F ± 1.0°F).
F.
Turn the unit OFF and unplug from the power source. Move both jumpers back
to the
Normal
position on the power supply board.
