4.05 Removal of Waste Cooking Oil from Fryer - continued
B. Removing Waste Oil from Fryer Using a Bulk Waste Oil Disposal System:
The following sub‐section explains the procedure for removing and disposing of waste cooking oil from fryer using a
connected, customer‐provided, waste oil collection/disposal system. The fryer must be equipped with the optional,
factory‐installed plumbing, that provides for a direct connection to a bulk system.
Before first use, confirm that fryer is properly connected in accordance with manufacturer’s instructions and
guidelines, and that the bulk system is in good working condition.
1. If the oil in vat is cold, heat it to at least 200°F (93°C).
2. The Power Switch
① must remain [ON], and the Heat
Switch
② must be in the [OFF] position. For a banked
system, power switch of the main unit with filter pan
must remain [ON].
3. For banked units, this step refers to the unit with filter
pan.
Ensure filter pan & pan cover ③ are in place. Check the
Filter Pan Hose ④ ... it must be properly and securely
connected at the coupling. Verify that the Discharge
Hose Valve handle ⑤ is in the [CLOSE] position.

The next steps require that cooking oil be
drained from the vat into filter pan, exposing
the heating elements. Although fryer has safety interlocks which
disable heating elements anytime drain valve is opened, always
place Heat Switch in the [OFF] position prior to draining, as a
further safeguard. NEVER USE THE DRAIN VALVE AS AN “ON/OFF
HEAT SWITCH”.
For muti‐well banked units, DO NOT drain more than one (1) vat at a time into the filter
pan! The pan has capacity to hold oil from ONLY one (1) cook vat
. Never disconnect and
attempt to remove the filter pan from unit while it contains cooking oil.
4. Slowly position Drain Valve Handle ⑥ to the [OPEN] position and allow oil to completely drain from vat into
filter pan, then return the drain valve handle to the [CLOSE] position.
IMPORTANT! When drain valve is opened, controller will issue a “DRAIN IS OPEN” error and sound the alarm.
Press the [ALARM] key to silence alarm. The error should be cleared 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.
6. Set the Pump Switch ⑪ to the [PUMP] position. Waste cooking oil will be pumped to the bulk waste collection
tank by the fryer’s filter pump. Either visually observe oil level in filter pan, or note when pump sound changes,
indicating that filter pan has emptied. Return Pump & Power switches to [OFF] position.
7. Return the Waste Valve handle ⑫ to the [CLOSE] position.
