2.1 General (cont.)

The used oil may be drained by gravity from the fryer into the filter pan, or removed from the fryer
by use of a suction/return hose, according to model. The oil is pumped back into the fryer vessel
using the same suction/return hose.

Oil or shortening is filtered through replaceable 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 frypots. All units are
adjusted, tested and inspected at the factory before shipment.

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 the aspects of

oil filtration, and draining/cleaning procedures.

A 7-amp (115V-domestic), or 5-amp (230V-international) circuit breaker installed on the filter unit
switches the power OFF if an overload occurs.

NOTE: If the circuit breaker is triggered, depress the reset button to activate the circuit after the

failure has been detected and repaired.

2.2 Rating Plate

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

2.3 Pre-Installation

NOTE: Failure to use qualified service personnel will void the Dean warranty.

A. Standards: Use of this filter unit must be in accordance with all applicable state and local

codes.

B. Electrical Connections: Domestic MF90 filter units require a 115V 60 Hz., 15 amp electrical

supply. Units are equipped with a grounded male receptacle for use with a flexible six-foot,
16-3 SJT power cord set. If an extension cord is required, it must be a three-conductor,
grounded power cord of at least 16 gauge.

2.4 Unpacking the Filter System

Ensure the container is upright. Unpack the filter carefully a nd remove all accessories from the
carton. Do not discard or misplace parts and/or accessories; they will be needed. Any
accessories or starter kits included with the unit will be packaged inside the filter tank 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, as the responsibility of shipping damage is between the carrier and dealer
or end-user.

If your equipment arrives damaged:
a. File claim for damages immediately – Regardless of extent of damage.
b. Visible loss or damage – Be sure this is noted on the freight bill or express receipt and is

signed by the person making the delivery.

c. Concealed loss or damage – If damage is unnoticed until equipment is unpacked, notify

freight company or carrier immediately, and file a concealed damage claim. This should be
done within 15 days of date of delivery. Retain the shipping container for inspection.

NOTE: Dean does not assume responsibility for damage or loss incurred in transit.

3.1 Assembling The Filter System

On initial installation and before each use, remove all loose parts from the filter, wash the
filter pan and all accessories in hot, soapy water and dry thoroughly.

Water or boil -out solution MUST not be allowed to drain into the filter pan or

filter system. Irreversible damage will result if water is allowed into the

system, and the warranty will be voided.

filter paper as evenly as possible. If filtering a second frypot immediately after the first,
add only 8 ounces of filter powder for the second filtering.

E. Place the crumb catcher screen (if used) in the filter pan. Allow the crumb catcher to rest

on the top edges of the hold-down ring.

F. Place filter pan cover onto the filter pan assembly.

G. Position filter under the fryer drainpipe for gravity drain operations, or nearby for suction
