Fryer Operation
GBF − 35 / GBF − 50 Fryers
4.03 Maintaining Oil Level w/ Optional Oil Top − Off Systems
During normal operation, cooking oil volume is depleted through
absorption, drag ‐ out, splash,
etc. Continuing to cook with the oil level consistently below the
[ADD] mark increases the risk
of oil fires. To help minimize this risk, the fryer controller has a built ­ in interlock that will issue a
LOW OIL LEVEL alarm & shutdown heating elements as a safeguard. To avoid such possible
interruptions & to ensure error ­ free operation, you should routinely monitor oil level between
loads cooked and replenished with fresh oil, as needed.
The
GBF fryer can be purchased with either of two different
optional oil top ‐ off capabilities ...
an on ­ board system or factory
­ installed plumbing for directly connecting to a customer ­
provided bulk oil management system (fresh supply and/or waste disposal) .
A. Using On ‐ Board Oil Top ‐ Off System (w/Saddle Tank):
The on ­ board system features an
oil storage tank , which hangs on the cabinet side. It has a capacity for approx.
11.5 gallons of fresh liquid shortening. A flexible hose with quick ­ coupling connects the tank
to an on ‐ board top ‐ off oil pump . A removable cover protects the stored oil from contaminates.
This single tank provides fresh oil to all wells of a multiple unit system.
The fresh oil supply in the tank must be monitored & manually maintained by operating
personnel. Tank can be easily removed
(without tools) for cleaning.
1. Before first use, thoroughly clean inside of tank & the cover ... allow to dry completely.
2. Hang tank on the cabinet bracket & connect the flexible hose. Fill tank with your preferred
fresh cooking oil (fill only to about 1” below top lip)
... place the top cover.
3. After every 2 or 3 loads cooked & after removing product from vat, check the oil level. If
level is at or below the
[ADD] mark, open cabinet door & place the OIL RETURN VALVE
handle in the [FILL POT] position. On a multiple system, the valves in all other units of the
battery must be in the [CLOSE] position .
4. Press & hold the ADD OIL control panel push ­ button switch . The top ­ off pump will start
to deliver fresh oil from the saddle tank to the vat. NOTE: There is only one push
‐ button
switch for a multi ‐ well battery, typically it will be on the unit with the filter pan.
5. The pump will only run while button is being pressed
... continue holding &
observe the vat filling. Release switch when level reaches the
[FULL] mark.
6. If the amber HEAT light turns ON while adding, stir oil until the light turns OFF
to ensure that the total volume of oil is at the cooking temperature setpoint &
is ready for the next load.
NOTE: Oil fill ports are located on the vat bottom ... if the vat is over half full, there may be no visible indication
of oil flowing into vat except for a rising oil level. Should the top
‐ off pump stop while pushbutton is being
pressed, possible excessive back ‐ pressure has built up in the system ... the pressure interlock switch has shutdown
pump to avoid damage. Confirm that proper FILL valve is open, check plumbing for blockages, etc.
Lack of oil flow may be due to empty saddle tank ... check that first!

B. Using a Bulk Fresh Oil Supply System:
Be sure that the fryer is properly connected to the bulk fresh oil supply according the system manufacturer’s
instructions & guidelines. The bulk system pump must be wired properly into the fryer control panel push
­ button
switch.
A single plumbing connection will provide fresh oil to all the wells of a multiple system.
