SERVICING INSTRUCTIONS (continued)

IMPORTANT:

Water pressure

must be between 20 p.s.i and

90 p.s.i. flowing pressure.

If water pressure exceeds this

value, or if water pressure

varies greatly, a pressure

regulator must be installed in

the water supply line.

IMPORTANT:

Before set-

ting assembly into tank, make

sure tank lid gasket is properly

seated on flange of lid.

IMPORTANT:

When mounting

thermostat, be sure a new seal

washer is placed below the

fitting on the capillary line.

Push sensing bulb thru tank lid

until fitting seats.

If replacing gray-bodied thermo

with p/n 8512-51, be sure to

remove tube from thermowell.

Tighten capillary lock nut only

enough to ensure no water

leakage. Excessive tightening

is not necessary.

SOLENOID TIME ADJUSTMENT

The amount of water dispensed automatically during a brew cycle

is controlled by the SOLENOID TIME section of the controller.
Place empty dispenser under brew chamber. Press the BREW

switch. Including both brew water and dilution water, brewer

should dispense:

A total of 3 gallons (Model 8742) of water; or,

A total of 5 gallons (Model 8748) of water.

solenoid is energized. Adjust timer; clockwise increases time;

counterclockwise decreases time. Run several cycles to check

total amount of water delivered.
