SETUP STEPS

1. The unit should be level (left to right - front to back), on a secure surface.

2. Install the supplied water faucet on the faucet shank in front of the unit.

NOTE: A water filtration system must be used to help maintain trouble-free operation. In areas with extremely hard water, we highly recommend the use of a Curtis approved water filter. (For our full line of filters, please log on to www.wilburcurtis.com) A water filtration system will greatly prolong the life of the unit and enhance the quality and taste of the product.

Setup Steps Continued

3. Connect the water line to the water inlet fitting on the rear of the unit. Water volume going to the machine should be consistent.

Use tubing sized sufficiently to provide a minimum flow rate of two gallons per minute.

4. Connect the unit to electrical outlet with appropriate amperage rating (refer to schematic for power requirements).

5. Turn on the circuit running power to unit. The water inlet valve will open, filling the unit. When the boiler has filled, turn on boiler at the thermostat, twisting the knob clockwise.

6. Heating tank will require 50 to 60 minutes to attain operating temperature. Thermostat indicator will light at this time.

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 out

3. Grounded probe

4. Defective water level control board

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.

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.

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 NEU and L1 120V. 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 the L.L.C. 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. Liquid level probe limed up

Disconnect the wire from probe terminal and touch the body of the heating tank with the terminal at the end of this wire. If the flow of water stops, there is an issue with the probe. Clean the probe and reconnect the wire. If water continues to flow, replace the liquid level probe.

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 is turned

OFF (or set too low)

SOLUTION

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

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.

4

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. Heating element burned

out.

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.

Electric Thermostat

Adjustment

ELECTRIC THERMOSTAT ADJUSTMENT

On electric water boilers, thermostats are set at the factory to cut off at 200ºF. We do not recommend changing this. If necessary, adjustment is as follows:

1. Rotate the thermostat knob to the right to the BOIL position. Pull off the knob.

2. Locate the tiny adjustment screw, inside the stem (see figure 1). Using a small screwdriver, adjust the temperature up or down: a. By turning the screw ¼ turn to the left will increase the temperature about 20°F.

b. Turning ¼ to the right will decrease the temperature by 20°F.

c. To set the thermostat precisely at 200°F, insert a thermometer probe into the water jacket through the steam hole (just under the sprayhead). Turn the screw ½ turn to the left. d. When the thermometer reaches 200°F, slowly turn the adjustment screw to the right until the pilot light turns off.

CLEANING

Regular cleaning and preventive maintenance is essential in keeping your water boiler looking and working like new. To clean the water boiler, prepare a mild solution of dish detergent and warm water. Turn the thermostat dial to OFF and allow the unit to cool.

CAUTION – Do not use cleansers, bleach liquids, powders or any other substance containing chlorine. These products promote corrosion and will pit the stainless steel. USE OF THESE PRODUCTS WILL VOID THE WARRANTY.

DAILY CLEANING

1. Wipe exterior surfaces with a damp cloth, removing spills and debris.

2. Remove the lid and clean it with a cloth soaked in a mild detergent solution.

3. Rinse and dry the lid.

4. Wipe off any traces of the cleaning solution with a cloth dampened with water.

5. Dry the cabinet surfaces.

6. Rub a stainless steel polish on the outside surfaces to protect the cabinet.
