WATER BOILER - WB-10 -12

INSTALLATION INSTRUCTIONS

1. Unpack equipment carefully, inspect for any freight damage. Be sure to promptly put a claim into the freight company if any damage is found.

2. Connect faucet securely to the faucet adapter.

Electrical and plumbing hook-ups should be made by authorized installers only.

INSTALLATION MUST COMPLY WITH ALL NATIONAL AND LOCAL ELECTRICAL AND

PLUMBING CODES.

3. This water boiler can operate on 120, 208 or 220 volt power supply. To ground equipment, connect the ground wire to the green screw on inside bottom of wrap.

4. This boiler comes wired for 208 or 220 volt, single phase, 3 wire plus ground, see wiring diagram.

5. To connect the water boiler for 120 volt operation:

A. The facility will have two wires, one WHITE (neutral) and the other BLACK. Plus

GREEN for ground.

B. Splice the BLACK wire from power source, to both the heavy RED (#10 AWG) and thin BLACK (#18 AWG) wires from the WB-10.

C. Take the WHITE wire from the facility power source and splice it to the BLUE wire

(#10 AWG) and WHITE wire (#18 AWG) from the machine (see wiring diagram).

6. Water Hook-Up: Use a 1/4" copper line with a female flare fitting. Water inlet fitting is located on the back of the WB-10.

CAUTION Before turning thermostat dial to ON position, fill equipment with water up to the probe tip. This will prevent heating elements from burning out.

TROUBLE SHOOTING

PROBLEM: WATER WILL NOT REFILL

POSSIBLE CAUSE

1 . Water line closed or clogged filter

SOLUTION

Check the water system at your facility to make sure the line is open. Replace the water filter.

2 . Valve coil burned o u t

Turn machine off. Disconnect wires from water inlet coil terminals and connect a power cord to the terminals. Plug cord into a 120V outlet and verify if water flows when plugged in and stops when power is disconnected. If valve fails this test, replace valve.

3. Grounded probe When the water level gets below the probe tip, water should automatically refill the unit. If not, pull wire off the probe terminal. Water should now start flowing into the water boiler.

4 . Defective water level control board

Disconnect wire from probe terminal. With a voltmeter, check voltage at the water inlet coil terminals. This should read 110-120 volts. If no voltage is present, check liquid level control (L.L.C.) board. Make sure the L.L.C. board is supplied by 120V across terminals T2 & T3. The L.L.C. board is grounded to the body of the machine by contacting the board to the mounting bracket.

Make sure board is grounded here. Check for loose connections at terminals. Replace board.

PROBLEM: WATER OVERFLOWING.

POSSIBLE CAUSE

1 . Defective water inlet valve

SOLUTION

Turn power off and observe water level. If water continues to flow into the heating tank, clean or replace leaky valve.

2 . Probe limed up Disconnect wire from probe terminal. Touch the body of the heating tank with the terminal at the end of this wire. If water stops, try cleaning the probe. Probe may have to be replaced.

3 . Non-grounded or loose terminal connections at liquid level control board

Liquid level control board must be securely grounded through the back of the board and the mounting bracket. Check for loose connections at the terminals. Check for voltage across the inlet valve terminals. If there is 110 to 120 volts present at the inlet valve terminals when water level is touching the probe tip, replace the L.L.C. board.

PROBLEM: WATER DOES NOT REACH PROPER TEMPERATURE

POSSIBLE CAUSE

1 . Thermostat turned OFF (or set too low)

SOLUTION

Check thermostat to make sure the shaft is knob is rotated clockwise to the desired temperature.

2

TROUBLE SHOOTING CONTINUED:

PROBLEM: WATER DOES NOT REACH PROPER TEMPERATURE

POSSIBLE CAUSE

2 . Defective thermostat

SOLUTION

Replace thermostat if contacts are open when knob is fully clockwise and water temperature is less than 190º F. You will measure 120 volts (approximately) to ground from both thermostat terminals when it is ON and from only one terminal when it is OFF.

3 . Burned out heating element

In this water boiler there are two elements in parallel. Failure of either will cause very slow heating. Perform the following tests: a. Clamp-on ammeter test: If both elements are good, you will measure about 21 amps at 240 volts, 24 amps at

208 volts or 29 amps at 120 volts. If you measure only 10 to 12 amps, check the current to each element to identify the defective part.

b . Ohmmeter or continuity test: Disconnect all power by unplugging unit. Disconnect one terminal to measure each element. They should each have continuity or measure about 20 ohms.

PROBLEM: WATER OVERHEATS, ELEMENTS DO NOT SHUT OFF

POSSIBLE CAUSE

1 . Defective thermostat

SOLUTION

Replace the thermostat. You can sometimes operate temporarily by turning the thermostat knob to off until the boiling stops.
