REMEDY
BUNN® paper filters must be
used for proper extraction.
A fine or drip grind must be used
for proper extraction.
A six-hole stainless steel spray-
head must be used for proper
extraction.
The BUNN® paper filter must be
centered in the funnel and the bed
of ground leveled by gentle shak-
ing.
Place an empty funnel on an empty
dispenser beneath the sprayhead.
Initiate a brew cycle and check the
water temperature immediately
below the sprayhead with a ther-
mometer. The reading should not
be less than 195°F. Adjust the
control thermostat to increase the
water temperature. Replace if nec-

Plumbing lines should not resting
on the counter top.
(A) The brewer must be connected
