For qualified service technicians
Equipment Setup
1. Read User Guide noting all instructions. Review the dimensions for the unit you are installing.
2.
Verify that it will fit in the space intended for it.
3. Verify that the counter or table will support the total weight of the equipment and any dispensers when filled.
4. Place the equipment on the counter or stand.
Water Connection
1. Water supply inlet is a ⅜ inch male flare fitting.
2. The HWD-2102 Hot Water Dispenser can be connected to a cold or hot water line.
3. (Cold water is preferred for best beverage flavor, but hot water will allow for greater output.)
4. Install a shut off water valve near the equipment to facilitate service. An in-line water filter should used and
installed after the water shut off valve and in a position to facilitate filter replacement.
5. Flush the water supply line and filter
before
connecting it to the unit.
6. Verify that the water line will deliver a flow rate of at least 1½gpm/ (5.7lpm) per minute and water pressure is
between 45-75 psig (0.31-0.517 mPa) (0.34MPa/50PSI preferred) before making any connections.
7. Use a wrench on the factory fitting when connecting the incoming water line. This will reduce stress on the
internal connections and reduce the possibility of leaks developing after the install has been completed.
Electrical Connection
:Always refer to the wiring diagrams when connecting equipment electrical utilities
8. If Cord Connected: Do not use multiple taps for the plug. Consult local codes to determine if a single circuit is
required for the cord and plug installed. Do not use extension cords for commercial food equipment
9. Terminal Block: The HWB-2100 model series requires grounded service to the terminal block (illus. 1)
10. Verify that the actual voltage at the electrical service connection is compatible with the specifications on the
equipment serial number label. Make sure the electrical service will match the current draw of the equipment.
11. Access the terminal block for electrical connection in the front of the unit by following the illustration above.
12. A fused disconnect switch or circuit breaker on the incoming power line must be conveniently located near the
equipment and its location and markings known to the operators.
13. The body of the unit must be grounded to a suitable building ground.
Tank Drain
The water tank must be drained before maintenance procedures, and when the unit is to be relocated or shipped.
14. Disconnect power to the unit.
15. Move the unit near a sink or obtain a container to large enough to hold four gallons of water.
16. Remove the tank cover and allow the tank to cool to a safe temperature.
17. The tank drain is located on the back of the unit. Turn the drain plug one-quarter turn in either direction.
18. Pull the plug out far enough to expose the silicone tube.
19. Using pliers loosen the hose clamp and move it back over the tube.
20. Crimp the tube an inch or two away from the drain plug to prevent water from flowing.
21. Use the other hand to pull the drain plug out of the tube.
22. Release the crimped tube and allow the water to flow into the sink or container. Tank capacity is 2.0 gal/7.5 liter

From HWD vent
Vent receiver and drain line
! Must provide air-gap to drain!
Attach a Vent Drain
NOTE
When the HWD_2102 is initially filled
and powered “ON”, water may flow from the
vent drain. This is normal, and caused by
expansion of the large amount of cold water in
the hot water tank.
All equipment with vent drains should be
attached to tubing that exits into a plumbed
drain system.
A drain line should be used for the tank vent.
Materials: use ¼” i.d. heavy wall silicone tubing
or 3/8”i.d. rigid tubing only.
IMPORTANT: Allow a 4” to 12" air-gap from the
end of the drain line to main drain.
NOTE
Consult local plumbing codes
.
