6.3 FILTER OPERATION:

Dean Filter Systems are designed to be
used as either a portable unit or a built-in
filter as part of a fryer/filter system.
Portable means that it can be moved from
fryer to fryer.
The primary difference between filter
systems is how the filtered oil is returned
to the fryer vessel. Built-in systems have
an internally-plumbed oil return line
running from the filter' s quick disconnect
to a special port in the fryer vessel' s rear
wall where oil re-enters the fryer vessel.
Portable systems return the filtered oil by
means of a flexible oil return hose which
connects to the filter' s quick disconnect.
The operator uses a wand connected to
the end of the flexible oil return hose to
direct filtered oil into the fryer vessel
from above.
Filter operations always start with making
sure the unit is properly plugged in, then
rolling the filter to the fryer to be filtered.
The filter works directly under the fryer's
drain valve.
