6-3 ● 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 mounting hardware and probe guards are 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 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, 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.
● 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 are present and in good condition. Replace O-rings and seals if worn or
damaged.
● Check filtration system integrity as follows:
− Verify that filter pan cover is present and properly installed.
− With the filter pan empty, place each vat into return to pan selection, one at a time. Verify proper
functioning of each oil return valve by activating the filter pump using the return to pan selection.
Verify that the pump activates and that bubbles appear in the cooking oil of the associated frypot.
− Verify that the filter pan is properly prepared for filtering, then drain a frypot of oil heated to 350°F
(177°C) into the filter pan by using the drain to pan selection (see page 4-21). Now using the fill pot
from pan selection (see page 4-22), allow all oil to return to the frypot (indicated by bubbles in the
cooking oil). Press the check button when all oil is returned. The frypot should have refilled in
approximately 2 minutes and 30 seconds.
