SECTION 3 maintenance
3.1 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. Assistance in
service methods or, a current Directory of Authorized
Service Agencies may be obtained from Market Forge.
(See Subsection 1.2).
3.2 PREVENTIVE MAINTENANCE
The most important preventive maintenance operation on
the steam jacketed kettle is the cleaning procedure after
each use described in Section 2. Additional preventive
maintenance operations are presented in this section.
3.2.1 Cleaning
A policy should be faithfully observed of completing, by
the end of each day's operation, all kettle cleaning
procedures explained in Subsection 2.4.
In addition, cabinet doors, top, fixtures, 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 Subsection 2.5 and washed in a
sink.
3.2.2 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 paragraph 3.3.5.).
3.3 REPAIR & REPLACEMENT
In the event that the kettle fails to operate correctly, the
difficulty should first be isolated to either the kettle itself
or the steam supply which heats the kettle. While
mechanical problems are obvious faults of the kettle, any
deficiencies 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
information may be found in separate service
publications for steam generators.
3.3.1 Lid Counterbalance Adjustment
The kettle lid is equipped with a torsion spring
counterbalance device to assist in lid lifting and to
prevent slamming. The device is shown assembled in
Figure 3-1 and exploded in Figure 4-11. 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:
1. Loosen 1/4" jam nut.
2. Adjust spring tension by turning 1/4" hex head cap
screw. Tighten to increase tension; loosen to reduce
tension.
3. Operate lid several times, repeating, step 2 until
desired operation is obtained.
4. Hold hex head screw firmly in position and
