Operation Manual
NI60A 04-2002
The Hot Water Dispenser is shipped, from the factory, with the Heater Switch in the "OFF" position. DO NOT turn
the heater switch ON until the unit is primed with water. The heater switch is located at the lower back of the unit.
WATER INLET CONNECTION :
The Hot Water Dispenser is to be installed to comply with all applicable Federal, State and Local plumbing codes.
Furthermore, a quick disconnect or enough extra coiled tubing, (at least 2 times the depth of the machine) should
be installed, so that the unit can be moved for proper cleaning underneath. It is recommended that an approved
back flow prevention device, such as a double check valve, and a shut-off valve should be installed between the
Hot Water Dispenser and incoming water supply.
START - UP PROCEDURE:
CAUTION: MAKE SURE THE HEATER SWITCH, LOCATED AT THE LOWER BACK OF THE UNIT, IS IN THE
OFF POSITION.
1. Connect a ¼" diameter copper waterline to the ¼" flare water inlet.
2. Open the water shut-off valve and check connections for leaks. DO NOT over-tighten.
3. Plug in the Hot Water Dispenser into a dedicated power supply outlet.
4. Activate the Power Switch (front of unit) the water tank will begin to fill, providing the water connection is open.
The tank will fill in approximately 3-4 minutes.
5. After the tank has filled, activate the Heater Switch (toggle up, lower back of unit). Depending on the model
selected, it will take approximately 15-25 minutes for the water to heat to operating temperature.
NOTE: This procedure is for initial start - up only; however, steps 4 and 5 must be repeated should the tank be
completely drained. Steps 1 thru 5 must be repeated should the machine be drained, disconnected and reinstalled
in a new location.
THERMOSTAT ADJUSTMENT:
Remove the two (2) screws from the top cover and remove cover. The thermostat, will be visible. First, adjust the
thermostat by turning the thermostat knob either clockwise to raise the temperature, or counter clockwise to lower
the temperature. If further adjustment is required, remove knob, turn the adjustment screw, located in the center of
the thermostat shaft, counter clockwise to increase the temperature and clockwise to decrease the temperature.
Unit should be set to approximately 203°F.
WARNING: Always disconnect HWD from power supply before repairing or replacing any internal components.
