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 temperature 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 temperature to stabilize as described in step 2 and repeat step 3. Continue until the desired water temperature 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.
