SERVICE
D. Return Unit to Service
1. Turn water supply on and check for leaks.
2. Connect Water-Max™ to electrical power.
3. Calibrate Delime Sensor. See drawing below.
a. Remove the plastic cover from the tank, then reinstall the
tank on the tank shelf. Tank must be empty to begin test.
b. Insert the thermocouple of a digital thermometer 6" into the
spout. Be sure thermocouple is into the silicone tube
section. Press the power switch ON.
Observe the action of
the DELIME LED.
c. Adjust TEMP OFFSET until the water at the spout is a
steady 197ºF. Allow at least 30 seconds of flow.
DELIME LED should just begin to flash as the water temp
decreases to 197ºF. If not; adjust DELIME on the
CONTROL BOARD until the DELIME LED just starts to
flash at 197ºF.
4. Calibrate Temperature. See drawing below.
a. Empty WATER TANK. Reinstall the plastic cover on the
tank, then install under DISPENSER NOZZLE. Press
POWER SWITCH to ON.
b. Run and discard at least one full tank of hot water to allow
dispenser temperatures to stabilize.
c. Turn TEMP OFFSET on the CONTROL BOARD so that
temperature on digital thermometer reads 202ºF.
d. Press POWER SWITCH to OFF.
5. Turn Water-Max™ OFF. Remove the thermocouple. Drain and
remove the tank. Properly reinstall all panels. Reinstall the
tank on the tank shelf. Turn POWER SWITCH ON.
6. Observe the tank fill and water flow stop. Draw water from the
tank and allow the tank to refill several times to verify proper
operation.
WARNING
Electric Shock
Hazard
Disconnect Water-Max™ from
electrical power before removing
any panel or cover.
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: 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.
