Model 648PROG can be used free-standing
or installed as a standard or flush built-in appli-
cation. For standard built-in installations, the
face frame of the unit will extend 2" (51)
beyond cabinetry. In flush built-in installations,
the front of the face frame will be flush with
surrounding cabinetry.
The depth of Model 648PROG from the back
of the unit to the front of the face frame is
7
25 / " (657). In flush built-in applications, your
8
design may necessitate moving the unit back,
or cabinets forward to achieve a flush fit.
The anti-tip bracket must be installed to
prevent the unit from tipping forward.
Allow the doors to open a minimum of 90˚ or
you'll have problems removing shelves. With
the door opening at 90˚, you may have to move
shelves slightly to clear the door interior. Refer
to the minimum door swing clearance in the
specifications chart.
For corner installations, allow for a minimum
3" (76) filler so that the door can open to 90˚.
Model 648PROG comes with an automatic
ice maker and an integrated water filtration
system. This system operates on water
pressure between 35 psi (2.4 bar) and 120 psi
(8.3 bar). To rough in the water supply, connect
