THERMOSTAT ADJUSTMENTS:
1. Remove hole plug (3, Fig. 1, 2) from the round hole on top of cover. Place a suitable thermometer in hole and immerse bulb approximately 4
inches.
2. If water temperature is less than 197° F (92° C) slowly turn thermostat slot stem, on back of brewer, clockwise until ready light goes out.
When temperature of water approaches 197° to 203° F (92° to 95° C) slowly turn thermostat stem counter-clockwise until the green ready
light comes on. If water temperature cannot be increased when thermostat shaft is turned fully clockwise, then proceed as follows:
Place a small screwdriver into the center of thermostat shaft. While observing green ready light and temperature on thermometer, hold shaft and
turn small adjustment screw in center counter-clockwise until green ready light goes out. When temperature of water approaches 197°-203° F
(92°-95°C), slowly turn screw clockwise until ready light comes on. Turning screw clockwise lowers temperature: counter-clockwise raises it.
After adjusting center screw, place nail polish or glyptol on screw to set in position.
NOTE: As a final check, measure water temperature at Spray Head (22, Fig. 1:15, Fig 2). Temperature should be 197° to 203° F (92° to 95° C).
TIMER ADJUSTMENTS (Automatic Models Only):
To increase volume of water, turn knob of timer (24, Fig. 1; 48, Fig. 2) clockwise. To decrease, turn knob counter-clockwise. Turn knob by small
increments.
NOTE: Timer must go through a complete cycle before another adjustment can be made. Timer cannot be adjusted once it has been initiated.
CAUTION; DISCONNECT POWER BEFORE ATTEMPTING ANY ELECTRICAL REPAIRS.
PROBLEMS WITH WARMER ELEMENTS & SWITCHES:
If warmer plate (20, Fig. 1:17, Fig. 2) fails to heat, first check power source. If power source is okay, check if light on warmer switch (15, Fig. 1;
18, Fig. 2) Is lit when in the "I" position. If warmer switch is lit, replace warmer plate by unplugging brewer, removing the two hold down screws
on plate and withdrawing warmer plate from brewer. Replace with new warmer plate. If warmer switch does not light, replace it. To remove
warmer switch press each tab behind front plate of brewer down with screwdriver in turn. As each tab is pressed, pop that corner of warmer
switch out of the front of brewer. New switch snaps in from the front.
IF WATER FAILS TO HEAT:
1. If amber power light (39, Fig. 1, 2) and warmer switches do not come on, check power source. Replace fuse or reset circuit breaker if
necessary. If power is good, check brewer wiring for continuity and replace damaged wire(s).
2. If amber power light is on, follow priming instructions; then press reset button on back of brewer and wait
approximately 15 minutes for water to heat and green ready light to come on. If water still fails to heat, disconnect line cord and check out tank
heater, (27, Fig. 1; 41, Fig. 2), thermostat (33, Fig. 1; 24, Fig. 2) and high temperature safety shutoff (35, Fig. 1; 43, Fig. 2). Replace needed
parts.
MAINTENANCE ON AUTOMATICS (CS2A. 3A. 2AWT. 3AWT)
IF NO WATER COMES FROM SPRAY HEAD: Check in the following order:
1. Water Supply Line
2. Line Fuse or Circuit Breaker
3. Solenoid (37, Fig. 1; 28, Fig. 2)
TESTING SOLENOID AND TIMER (CS2A & CS3A):
Make sure brewer is properly primed. Turn on power switch; then press brew switch and hold for one minute. If solenoid buzzes and water flows
through spray head when brew switch is pressed and held, but stops when switch is released, timer is defective. Replace it. If no water flows
from spray head, and solenoid is inactive, first check brew swi t ch and wiring to solenoid and replace or repair as necessary. If brew switch and
wiring are okay, solenoid is at fault.
COFFEE BREWERS WITH HOT WATER SPIGOT (CS2AWT & CS3AWT):
1. When hot water is drawn for purposes of making tea, decaffeinated coffee or instant soup it is automatically replenished by means of a water
level control built into the system. Proper water level inside the tank is maintained at all times.
2. The outstanding feature of this water level control is its unique "Safe-Guard" circuit w hich prevents possible flooding which may be caused by
electrical component failure (i.e. switches, timer, level control sensor or solenoid, see Trouble Shooting guide for diagnosis). Problems with
any of the components will also be visually indicated by the red (LED) light. To reset the safeguard system, simply shut the power switch OFF
and then turn on again. 3. If there is no water coming out from the spray head when brew switch is depressed or if water does not refill when
hot water is drawn, check the following:
A) If LED light is on at the front, shut off the power switch and turn on again. This will reset the level control and automatic refill cycle. If LED
light goes off and there is no auto refill, proceed as follows:
1. Disconnect power.
2. Disconnect red wire from solenoid and also disconnect red wire from liquid level control (Terminal "Timer" —2nd from right side) (46,
Fig. 1; 30, Fig. 2), and connect this wire to solenoid, then perform solenoid test described in "Testing Solenoid and Timer" after
reconnecting power.
4. Disconnect power. If system operates but does not refill automatically, proceed as follows:
Connect the wire back to original wiring. Remove one wire on "Probe" terminal of water level control (Top one on left side of control).
Reconnect power and turn on power switch. If solenoid activates, water level control is operating normally. If Solenoid fails to activate, the
water level control is probably defective. Check the wiring for proper connection & continuity.
