START-UP
1. Remove top cover of brewer. Remove lid from heating tank. Hand fill tank until water level is
approxmately two inches below probe tip.
2. Connect the water line to the brewer using ¼" copper tubing with ¼" female flare fitting.
3. Turn on water.
4. With top cover removed, locate the thermostat (see illustration, page 8, #37), turn the thermostat shaft
clockwise until it stops. The BREW READY indicator light will go off when the thermostat is on.
5. Plug unit into power supply outlet and flip power switch (behind unit) to ON position. Turn ON/OFF
switch to ON position. Water should flow into heating tank. Check to see that the water stops flowing
when it reaches the probe tip. When this is verified, replace the tank lid and top cover of machine.
6. The warm-up time for the water in the tank to reach brewing temperature is from 15 to 20 minutes. The
BREW READY indicator light will come on when the water is hot enough to start brewing.

CARE AND MAINTENANCE OF C500AP
Preventive maintenance is essential in keeping your Curtis coffee brewer performing at it's peak. Regular
cleaning will pay off with an appealing, high performance coffee brewing machine.
Preventive Maintenance
1. Remove the sprayhead from brewer and clean it once a week; more often in heavy lime areas.
2. The inside of the heating tank may, occasionally, require removing of lime build-up. The
frequency is determined by local water conditions.
WARNING - When cleaning the unit, do not use cleansers, bleach liquids, powders or any other
substance containing chlorine. These products will promote corrosion and will pit the stainless steel.
USE OF THESE PRODUCTS WILL VOID YOUR WARRANTY.
Daily Cleaning
Using a daily routine of cleaning the external parts of the C500AP should maintain it's new appearance and
insure that the flavor of the coffee is always good.
1. Wipe off any spills, dust or debris from exterior surfaces.
2. Rinse out the brew cone.
3. Clean sprayhead and dome using a non-toxic cleaner and a damp cloth.
4. Clean the brew cone slide rails with a brush or damp cloth. Dry thoroughly.
Stainless Steel Polish can be used to clean the outside surfaces of the C500AP coffee brewer. This is to
prevent scratching of the stainless steel surfaces.
TROUBLE SHOOTING:
PROBLEM: WATER DOES NOT FLOW INTO HEATING TANK.
POSSIBLE CAUSE
1. Water line turned off
or water filter needs
changing
2. Water inlet valve coil
burned out
Make sure the brewer is receiving enough water pressure. Open the
water line and verify water flow.
Turn the power 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 or coil.
SOLUTION
3. Grounded probe
When the water level gets below the probe tip, water should automatically refill the tank. If not, pull wire off the probe terminal. Water should
now start flowing into the tank. If not, check the water level control board
(see step 4) or inlet valve (step 5).
