Temperature Calibration - Wells WATER-MAX Owner's Manual

CALIBRATING TEMPERATURE
CAUTION
:
SHOCK HAZARD
Removal of the top, front or
side panels results in
exposed electrical circuits.
Setting the temperature must
be performed by a qualified
technician only.
Use care whenever working
around exposed electrical
circuits.
NOTE:
Refer to Table 1 below right.
The practical maximum
temperature is the local
boiling temperature (based
on the altitude of the
installation) minus 10ºF.
If the stream is "sputtering",
water temperature is set too
high, allowing steam to form
in the water flow. Set TEMP
OFFSET lower to
compensate.
Remove TOP PANEL. Insert the thermocouple of a digital thermometer
at least 4" into DISPENSER NOZZLE.
Install WATER TANK under DISPENSER NOZZLE. Press POWER
SWITCH to ON.
Run and discard at least one full tank of hot water to allow dispenser
temperatures to stabilize.
Temperature is factory set for 202ºF. Turn TEMP OFFSET on the
CONTROL CIRCUIT BOARD so that temperature on digital
thermometer reads 202ºF.
Press POWER SWITCH to OFF.
Upon completion of temperature adjustment, properly reinstall all
panels.
