The correct B.O.M. sprayhead 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 ground coffee leveled by gentle
shaking.
Empty the server, remove its cover,
and place the server beneath the
sprayhead. Place empty funnel over
the server entrance, with ON/OFF
switch in the "ON" position press
the start switch and release it. Check
the water temperature immediately
below the sprayhead with a ther-
mometer. The reading should not
be less than 195˚F (91˚C).
