3.2 Periodic/Annual Maintenance
Frymaster recommends that the fryer be inspected annually by a Factory Authorized Service
Technician for the following checks and adjustments:
•
Inspect the cabinet inside and out, front and rear for excessive oil build-up and/or oil migration.
•
Verify that the heating element wires are in good condition and that leads have no visible fraying
or insulation damage and that they are free of oil migration build-up.
•
Verify that heating elements are in good condition with no carbon/caramelized oil build-up.
Inspect the elements for signs of extensive dry-firing.
•
Verify that the tilt mechanism is working properly when lifting and lowering elements and that
the element wires are not binding and/or chafing.
•
Verify the heating-element amp-draw is within the allowed range as indicated on the appliance’s
rating plate.
•
Verify that the temperature and high-limit probes are properly connected, tightened and
functioning properly, and that the mounting hardware and probe guard is present and properly
installed.
•
Verify that component box and contactor box components (i.e. computer/controller, relays,
interface boards, transformers, contactors, etc.) are in good condition and free from oil migration
build-up and other debris.
•
Verify that component box and contactor box wiring connections are tight and that wiring is in
good condition.
•
Verify that all safety features (i.e. contactor shields, drain safety switches, reset switches, etc.)
are present and functioning properly.
•
Verify that the frypot is in good condition and free of leaks and that the frypot insulation is in
serviceable condition.
•
Verify that all wiring harnesses and connections are tight and in good condition.
Built-in Filtration:
•
Inspect all oil-return and drain lines for leaks and verify that all connections are tight.
•
Inspect the filter pan for leaks and cleanliness. If there is a large accumulation of crumbs in the
crumb basket, advise the owner/operator that the crumb basket should be emptied into a fireproof
container and cleaned daily.
•
Verify that all O-rings and seals (including those on quick-disconnect fittings) are present and in
good condition. Replace O-rings and seals if worn or damaged.
