Built-In Filtration System - Frymaster OCF30 Series Installation & Operation Manual

5.7.2 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 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. Ve-
rify 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 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 cooking 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.
