1. If oil is cold, heat it to at least 200°F (93°C) .
2. The POWER switch ① must remain [ON] & HEAT switch
② must be [OFF] . For a banked system, POWER switch
of the main unit with the filter pan must remain [ON] .
3. For banked units, this step refers to the unit with the
filter pan.
Ensure filter pan with cover ③ are in place. Check the
FILTER PAN COUPLING ④ ... hose must be properly &
securely connected at the coupling. Verify that the

then return the valve handle to the [CLOSE] position.
IMPORTANT! When drain valve is opened, controller will issue a “DRAIN IS OPEN” error & sound the alarm.
Press the [ALARM] key to silence ... error should clear when drain is re
‐ closed.
5. After all oil has drained into filter pan, set the Waste Valve handle ⑫ to the [OPEN] position (vertical) . Waste
valve is located in unit with filter pan on banked systems .

The next steps require that cooking oil
be drained into the filter pan, exposing
the heating elements. Although fryer has safety interlocks
which disable heating elements anytime drain valve is
opened, always place HEAT switch to [OFF] prior to
draining, as a further safeguard. NEVER USE THE DRAIN
VALVE AS AN “ON/OFF HEAT
SWITCH” .
For multi ­ well banked units, DO NOT drain more than one (1) vat at a time into the filter
pan! The pan capacity is for ONLY one (1) vat of oil. Never disconnect & attempt to remove
the filter pan from the cabinet while it contains cooking oil.
NOTE: The pump system is equipped with a pressure sensor & switch. Should a condition create excessive
back
­ pressure (clog, full collection tank, etc.), the pump will shutdown to prevent possible damage. Should
this occur, cease pump operation & have maintenance personnel inspect the system.
