MAINTENANCE
WARNING:
DO NOT hOSE DOWN UNIT AS IT
CONTAINS ELECTRICAL COMPONENTS.
GENERAL
This section contains both preventive and corrective
maintenance information. Preventive maintenance
may be performed by maintenance personnel at the
establishment in which the kettle is installed.
It is recommended that user personnel never attempt
to make repairs or replacements to the equipment
without the assistance of authorized service. Assis-
tance in service methods or, a current Directory of
Authorized Service Agencies may be obtained from
Market Forge. (See service section on page 1).
PREVENTIVE MAINTENANCE
The most important preventive maintenance opera-
tion on the steam jacketed kettle is the cleaning pro-
cedure after each use described on page 3. Addition-
al preventive maintenance operations are presented
in this section.
CLEANING
A policy should be faithfully observed of completing,
by the end of each day’s operation, all kettle cleaning
procedures explained in cleaning procedure section
on page 3.
In addition, cabinet doors, top, xtures, kettle lid, etc.,
should be washed and rinsed to remove all food spills.
For Chill Kettles, extra care must be given to cleaning
the sink surrounding the kettle. Pan support should
be removed as described in pan support mounting
tilting kettles on page 5.
TILTING MEChANISM LUBRICATION
Lubrication of the tilting mechanism of 25-, 40- and
60-gallon tilting kettles is the only required preventive
maintenance other than daily cleaning. Inspect the
screw of the tilting mechanism annually for adequate
lubrication.
Should screw appear “dry” apply a good grade of
ball bearing grease directly on the threads so that
the threads appear to be barely damp. If mechanism
fails to run smoothly (see tilting mechanism repair on
page 7).
REPAIR & REPLACEMENT
In the event that the kettle fails to operate correctly,
the difculty should rst be isolated to either the ket-
tle itself or the steam supply which heats the kettle.
While mechanical problems are obvious faults of the
kettle, any deciencies in volume and pressure of
steam should be traced to the steam generator and
the cause determined.
Steam input requirements are listed in Appendix A,
Modular Kettle Steam Requirements. Additional infor-
mation may be found in separate service publications
for steam generators.
LID COUNTERBALANCE ADjUSTMENT
The kettle lid is equipped with a torsion spring coun-
terbalance device to assist in lid lifting and to prevent
slamming. The device is shown assembled in the
Figure 2 below and exploded in Figure 8, on page 15.
If lid slams closed when handle is released, spring
tension should be increased. If lid lifts up or refuses
to remain down on kettle, tension should be reduced.
To adjust spring tension proceed as follows:
Loosen 1/4” jam nut.
Adjust spring tension by turning 1/4” hex head
cap screw. Tighten to increase tension; loosen to
reduce tension.
Operate lid several times, repeating, step 2 until
desired operation is obtained.
Hold hex head screw rmly in position and tighten
jam nut to lock adjustment.

CABINET ExTERIOR REMOVAL
Side and rear panels of all cabinets in which kettles
are mounted are easily removed without the use of
tools. Each panel is grasped at the bottom edge and
pulled out sharply to release it from the panel mount-
ing brackets Shown in Figure 8, on page 15.
