5. Water temperature
1. Solenoid Valve
2. Plumbing lines

Remedy
The brew cycle should be started
only with an empty decanter under
the funnel.
BUNN® paper filters should be used
for proper extraction.
A sufficient quantity of fine or drip
grind coffee should be used for
proper extraction.
B.O.M. sprayhead #01082.0000
should be used to properly wet the
bed of ground coffee in the funnel.
The BUNN® paper filter should be
centered in the funnel and the bed of
coffee leveled by gentle shaking.
Place a funnel over an empty de-
canter on the warmer beneath the
sprayhead. Place the On/Off brew
station warmer switch in the upper
position, press the start switch,
and check the water temperature
immediately below the sprayhead
with an accurate thermometer. The
reading should not be less than 195°
F. Adjust the control thermostat
slightly clockwise to increase the
water temperature.
The nut on top of the solenoid valve
must be tight or it will vibrate during
operation.
Plumbing lines should not rest on
the counter top.
(A) The brewer must be connected
to a cold water line.
(B) Water pressure to the brewer
must not be higher than 90 psi.
Install a regulator if necessary to
lower the working pressure to ap-
proximately 50 psi.
