A. Preparing Fryer for Filter Process:
1. If necessary, press [ALARM] key ① to silence alarm. Ensure
that Power Switch ② is in the [ON] position as power for the
unit being filtered must remain [ON] throughout the process.
2. Place the Heat Switch ③ of the unit being filtered in the
[OFF] position. As added precaution against accidental oil fire,
the switch must remain [OFF] throughout the process. 2

3. Open cabinet door (unit w/filter pan on banked units) . Disconnect the filter pan
hose ④ (push in white slip ‐ ring, and pull hose from connector). Pull filter pan
from unit. Remove filter pan cover and the lift ‐ out crumb screen ; dispose of any
collected crumbs and residue.
4. Inspect to ensure that filter media (typically paper) is in place and that majority of
residue from any previous filter cycle has been cleaned from the surface. Ensure
that the
hold ‐ down frame is properly locked in place.

5. Evenly distribute approximately 5 ozs. of a suitable filter aid over the filter media surface.
Use of a good quality filter aid is essential for removing soluble impurities and reconditioning
the oil.
Portion packed Filter Powder is available through Giles’ distributors and equipment
dealers ... P/N 72004 .
6. Replace the crumb screen and pan cover , then reposition assembled filter pan under the unit
and reconnect hose ④ (push in white slip ‐ ring while inserting brass fitting into coupling). Filter hose must fit
tight and secure.
7. Confirm that Heat Switch remains in the [OFF] position and the Power Switch remains in the [ON] position
(switch must be [ON] throughout the filter process) .
8. On the unit being filtered , remove baskets and the support/crumb screen from the vat.
During the following phase, cooking oil is drained from the vat, exposing the heating
elements. Though safety interlocks are active, failure to keep the
Heat Switch in the [OFF]
position while draining could increase the risk of an oil fire. ALWAYS BE SURE THAT THE HEAT SWITCH
REMAINS IN THE [OFF] POSITION DURING THE FILTERING PROCESS .
•
For Banked Units: DO NOT drain more than one (1) vat at a time into the filter pan!
It ONLY has the capacity to hold the oil of one (1) cook vat.
•
Never disconnect and attempt to remove the filter pan from unit while it contains cooking oil.
