Welbilt Frymaster McDonald's LOV BIGLA30 Gen II Series Installation, Operation And Maintenance Manual page 75

There are no periodic preventive maintenance checks and services required for your FootPrint Pro Filtration
System other than daily cleaning of the filter pan with a solution of hot water and McDonald's All Purpose
Concentrate.
If you notice that the systems is pumping slowly or not at all, verify that the filter pan screen is on the bottom of
the filter pan, with the pad on top of the screen. Verify that the two O-ring(s) on the fitting at the right front of the
filter pan are present and in good condition.
6.2.4 Clean around AIF and ATO sensors
1. Clean the sediment from around the AIF and ATO sensors during maintenance
filtration when the oil is drained from the frypot.
2. Use a screwdriver or other similar object which allows access around the probe
(see photo right). Use caution to ensure that the probe is not damaged.
3. Return the oil once the maintenance filtration is complete.
6.3 WEEKLY CHECKS AND SERVICE
6.3.1 Clean Behind Fryers
Clean behind fryers in accordance with the procedure detailed in the maintenance requirement card. Shut off and
disconnect the gas. Use the manual gas shut-off valve to shut off the gas supply. The manual gas shut-off valve is locat-
ed on the supply line before the quick disconnects. Then disconnect the gas line from the fryer via the quick disconnect.
To ensure the safe and efficient operation of the fryer and hood, the electrical plug for the
120-volt line, which powers the hood, must be fully engaged and locked in its pin and sleeve
socket.
6.3.2 Cleaning the Frypot - Quarterly
Never operate the appliance with an empty frypot. The frypot must be filled with water or oil
before lighting the burners. Failure to do so will damage the frypot and may cause a fire.
6.3.2.1 Deep Clean (Boiling Out) the Frypot
During normal usage of your fryer, a deposit of carbonized oil will gradually form on the inside of the frypot. This
film should be periodically removed by following the deep-clean (boil-out) procedure contained in Kay Chemical
"Fryer Deep Clean Procedure" instructions. Refer to page 4-25 for specific details on setting up the computer for
deep clean (boil-out) operation.
Allow oil to cool to 100ºF (38ºC) or lower before draining to an appropriate container for
disposal.
Never leave the fryer unattended during this process. If the solution overflows, press the
ON/OFF switch to the OFF position immediately.
Ensure that the frypot is completely free of water before filling with oil. When the oil is
heated to cooking temperature, water in the frypot will cause splattering.
