filter screen is in place.

4. Ensure that the FKF filter unit or portable filter unit is plugged into the filter power receptacle.

5. Move the DRAIN handle slowly to the OPEN position until the shortening starts to flow

evenly. This will prevent excessive splashing of hot shortening.

7. Make certain that the rinse hose is connected to it’s mating part on the FKF filter unit or

portable filter unit.

8. Holding the hose by the handle, place hose nozzle inside the vat.

shortening.

12. Let the filter continue to pump the shortening until the fill mark in the fryer vat is reached or

until air starts bubbling through the shortening.

13. As soon as air is seen in the shortening, position the

FILTER MOTOR

switch to

OFF

to

prevent shortening degradation.

14. Add new shortening if the fill mark has not been reached.

Boil-Out Procedure

Boil-outs remove microscopic particles of carbon that build up on the walls of the fryer vat. To avoid
eventual carbon build-up, off flavors, and shortening breakdown, boil-outs should be done once a week
on each fryer following these procedures.

Always wear appropriate personal protection equipment during the boil-out
process to guard against possible injury from hot cleaning solution.

1. Position

the

POWER

switch to

OFF

.

2. Drain the clean shortening into an adequate storage container. (

Allow the shortening to cool to

room temperature before attempting storage

.)
