Fryer Operation
GBF-50 Fryer
13. After vat has refilled, return Pump Switch ⑨ to [OFF] position, then
immediately return the Oil Return Valve Handle ⑧ of the unit being filtered
to the [CLOSE] position.
14. Check oil level in the vat ... add if below [FULL] level.
Oil Return Valve(s)
must remain in the [CLOSE] position except when filtering oil or filling vat. Failure to do so
can allow oil to siphon back to the filter pan, causing a low oil error/alarm and cooking interruption.

8. Verify that Heat Switch remains in the [OFF] position, Power Switch must
remain ON. In the lower cabinet (on banked system, unit w/filter pan),
place the Pump Diverter Valve Handle ⑥ in the [OIL RETURN] position
(horizontal). Slowly move Drain Valve Handle ⑦ of the unit being
filtered, to the [OPEN] position (right to a stop). Oil should begin
draining into the filter pan.
NOTE: Add‐on units in banked systems do not have a pump diverter
valve, or the other filter pan features.
NOTE:
If oil does not readily drain, use the provided round bristle Drain Brush
to break up crumbs or residue that may be clogging the vat drain.
While draining, be sure filter pan cover remains in place to help contain
oil splash & splatter.

9. On the fryer unit being filtered
, set the Oil Return Valve Handle ⑧ to the [FILL POT] position (horizontal). On
banked systems, Oil Return Valves of all other units MUST be in the [CLOSE] position (vertical).
10. When oil has completely drained from vat, set the Pump Switch ⑨ to the [PUMP] position. On banked fryer
systems, this switch is only located on the control panel of the main unit with the filter pan. Other panels
units do not have the switch.

11. The oil will circulate ⑩ through the media and filter aid
contained in the filter pan and return to the vat. Leave the
drain valve open, allowing oil to continually circulate
through the system for about 5 minutes to act as a “crumb
wash”. During this time, use the provided brushes to scrub
vat sides & heating elements to remove cooking residue, so
that it can be flushed into the filter pan.
12. After about 5 minutes, return Drain Valve Handle ⑦ to the [CLOSE]
position. Filtered & reconditioned oil will begin flowing into the vat to
refill. Typically, when pump discharge starts creating bubbles in the oil,
refilling is complete.
