• 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 Power Shower and on quick-disconnect
fittings) are present and in good condition. Replace o-rings and seals if worn or damaged.
• Check filtration system integrity as follows:
− 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 cooking oil/shortening (or that gurgling is
heard from the Power Shower port) 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 (or no gurgling
should be heard from the Power Shower ports).
− 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 cooking oil/shortening to return to the frypot (indicated by bubbles in the
cooking oil/shortening or, on units with Power Showers, cessation of oil flow from the Power
Shower). Return the oil return handle to the OFF position. The frypot should have refilled in no
more than 2 minutes and 30 seconds.
5.2 Fryer Troubleshooting
Below are simple checks that should be performed before contacting the FASC:
♦ Is the ON/OFF switch in the ON position?
♦ Is the drain valve completely closed?
♦ Is the face of the fryer’s power plug flush with the outlet plate (i.e., no part of the prongs visible)?
♦ Is the circuit breaker set in the ON position and are fuses OK?
♦ Is the computer display blank? Check the hood cord (small cord), ensuring it is pushed fully into
the socket. Also check the ANSUL/hood system.
♦ Does the display show ignition failure? If so, turn off the fryer, open the drain valve slightly then
close it. Attempt to operate the fryer.
♦ Does the fryer remain below setpoint temperature? If so, verify that the face of the plug is flush
with the outlet plate (i.e., no part of the prongs visible). Also check the circuit breaker.
♦ Does the computer display on a split-vat unit show ignition failure? If so, turn off both vats. Turn
on the one that displayed ignition failure first, then turn on the other vat.
