Adjustments
The H5X dispenser holds the water temperature at
the threshhold of boiling. It is not adjustable by the
user.
The H5E dispenser is factory calibrated for the tem-
perature specified on the data plate. If adjustment is
required, use the following procedure:
1. Fill the dispenser according to the steps in the Ini-
tial Set-up.
2. Place the tank heater switch in the “ON” position
and observe the glowing red indicator near the right
edge of the control board. The controller is apply-
ing full power to the heater when the indicator is
on all the time. The indicator will begin to flash as
the temperature nears the set point. The set tem-
perature is reached when the indicator flashes only
very briefly. The water is hotter than the set tem-
perature when the indicator remains off.
3. Take the temperature of the stream of water imme-
diately below the faucet as it flows from the dis-
penser with an accurate thermometer. Do not take
the temperature of water collected in a container.
4A. TO INCREASE THE TEMPERATURE
Turn the adjustment screw in a clockwise direction
with a small screwdriver. Allow the temperature to
stabilize as described in step 2 and repeat step 3.
Continue until the desired water temperature is
achieved.
4B. TO DECREASE THE TEMPERATURE
Turn the adjustment screw in a counterclockwise
direction with a small screwdriver. Draw a large
quantity of water at the faucet, allow the tempera-
ture to stabilize as described in step 2 and repeat
step 3. Continue until the desired water tempera-
ture is achieved.
NOTE - The entire adjustment span is approximately
25 complete revolutions. The potentiometer will cease
to adjust when turned too far in either direction. It is
not damaged, simply turn it back a few turns and try
again.
