• Verify that all safety features (i.e. contactor shields, drain safety switches, reset switches, etc.)
are present and functioning properly.

serviceable condition.
• Verify that all wiring harnesses and connections are tight and in good condition.
Built-In Filtration System
• 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 the quick-disconnect fittings) 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 oil return handle, one at a time, in the ON position. Verify
that the pump activates and that bubbles appear in the oil of the associated frypot.
− Close all oil return valves (i.e., place all oil return handles in the OFF position). Verify proper
functioning of each oil return valve by activating the filter pump using the lever on one of the oil
return handle microswitches. No air bubbles should be visible in any 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 and close the frypot drain valve. Place the oil return handle in
the ON position. Allow all oil to return to the frypot, indicated by bubbles in the oil. Return the
oil return handle to the OFF position. The frypot should have refilled in no more than 2 minutes
and 30 seconds.
