Perform a flue inspection (600 only)
Disassemble condensation box, clean, and seal seams w/silicone
Rear of Fryer and front of the fryer - Check that the condensation box drain line, dead weight tube, pressure release tubing is free and clear from clogs. Also that each is not damaged or leaking.
Inspect drain pan, filter motor and drain oil.
Verify the drain valve handle microswitch is in working condition
Inspect that drain pan is empty, all components present (filter screen, clips, crumb catcher, standpipe, lid) and it is assembled correctly
Test filter pump motor to ensure operation
Drain oil to drain pan. Ensure no drain obstructions.

Inspect the high limit. Refer to inspection instructions.
Pump Oil / Fill Fry Pot
Test filtration system when pumping oil back up – no obstructions, leaks or excessively slow pumping.
Check that amp draw is correct and matches the data plate. (500 only).

Remove solenoid valve and clean and reassemble
Verify the existing pressure gauge rests at zero and is free and clear from obstructions. (verify during pressure test)
Pressure test with at least a half load of product (at least 3 lbs) and verify lid locks at pressures greater than 2psi and then unlocks only when pressure drops below 2 psi.
Verify in this test if pressure is regulating in the green zone. Verify that all pressure releases prior to the timer reaching 0:00. This will help to identify if there is still any pressure release and deadweight tubing obstructions.
During Pressure Test
Verify pressure gauge is functioning in a similar range as the calibrated test fixture
Inspect the oil return valve for leaks while under pressure. Verify there is no oil leaking back through the oil return plumbing to the drain pan while under pressure.
