2. IMPORTANT INFORMATION
2.1 GENERAL:
The MF-90 portable oil
filters may be used with a variety of Dean
fryers, as well as other manufacturers’
equipment.
The used oil may be drained by gravity
(MF90-U/110) from the fryer into the
filter pan, or, on some models, MF90-
AU/110, removed from the fryer by use of
a suction/return hose. It is then pumped
back into the fryer vessel by means of the
suction/return hose and nozzle assembly.
Filtering is accomplished through two
sheets of replaceable filter paper assisted
by a micro pre-coat filter powder.
2.2 OPERATING CONTROLS:
Two types of portable filters are available.
The most common is “return only”.
Primary filter control on the MF90-U/110
model is a two-position switch (on/off), or
on units with the optional heater, a three-
position switch (on/off/heater) is used.
The other type is “suction/return”.
Control on the MF90-AU/110 is by a
three-position switch (in/off/out). A pair
of swing-type check valves controls the
direction of oil flow. If any of these units
has an optional pan heater, the heater
switch is also mounted on the panel.
In many cases, a 60-minute timer may also
be activated to start the unit.
2.3 SAFETY FEATURES:
On the
larger capacity filters, a 5-amp (230V) or a
7-amp (115V) circuit breaker switches the
power OFF if an overload occurs.
NOTE
: If circuit breaker is triggered, depress
the reset button to activate the circuit
after the failure has been detected and
fixed.
2.4 RATING PLATE:
Information on
this plate includes the model and serial
numbers as well as electrical requirements.
This data is essential when contacting the
factory about a unit or ordering special
parts.
2.5 PRE-INSTALLATION:
a.
STANDARDS:
Usage of this filter
unit must be in accordance with all
applicable state and local codes.
b.
ELECTRICAL CONNECTIONS:
This unit requires connection to a
230V, 15 amp electrical supply. The
unit is equipped with a 3-wire, 16
AWG power cord. If an extension
cord must be used, it must be a three
conductor, grounded power cord of at
least 16 AWG.
2.6 UNPACKING THE FILTER:
Before unpacking, make certain the
container is upright. Unpack the filter
carefully and remove all accessories from
the carton, being careful not to discard or
misplace any parts, as they will be needed.
Loose parts include a starter kit and
accessories that may have been ordered.
These are packaged inside the filter tank.
The tank top is strapped to the shipping
frame.
After unpacking, immediately check the
equipment for visible signs of shipping
damage. If such damage has occurred,
contact the carrier and file the appropriate
freight claims. Do not contact the factory,
the responsibility of shipping damage is
between the carrier and the dealer or end-
user.
CAUTION
The on-site supervisor is responsible for
ensuring that operators are made aware of the
inherent dangers of operating a hot oil filter
system, particularly aspects of oil filtration,
draining, and cleaning of the filter.
