CHAPTER 2: IMPORTANT INFORMATION

2.1 General (cont.)

Oil or shortening is gravity-drained from the fryer into the filter ("S" Models), or pumped from the
frypot into the filter pan, and then filtered through filter paper. Filter powder, which enhances the
filtering process, is distributed over the paper prior to filtering.

All units are shipped completely assembled with accessories packed inside the filter pan. All units
are adjusted, tested and inspected at the factory before shipment.

WARNING

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 the aspects of

oil filtration, and draining/cleaning procedures.

An Off/Return (MPF50S) switch
activates/deactivates the filter pump. The filter
also has a Heater/Filter switch for use when
filtering solid shortening.

A thermal-overload switch on the pump motor

MPF50S switch/light panel

provides protection against overheating.

NOTE: If the thermal overload is triggered,

wait 45 minutes, and then press the
reset button to activate the circuit after
the failure has been detected and
repaired.

The motor thermal overload switch (arrow) is
located on the left side of the filter.

2.2 Rating Plate

Information on the rating plate includes model and serial numbers, as well as electrical requirements.
The rating plate is located on the back housing, near the electrical receptacle. Have the rating plate
information handy when communicating with the factory about a unit or requesting special parts or
information. Without rating plate information, proper identification of the unit cannot be confirmed.
