CHAPTER 4: FILTRATION INSTRUCTIONS
4.1 Introduction
The FootPrint Pro filtration system allows the oil in one frypot to be safely and efficiently filtered
while the other frypots in a battery remain in operation.
Section 4.3 covers preparation of the filter system for use. Operation of the system is covered in
section 4.4.
WARNING
The on-site supervisor is responsible for ensuring that operators are made aware of
the inherent hazards of operating a hot oil filtering system, particularly the aspects
of oil filtration, draining and cleaning procedures.
4.2 Draining and Manual Filtering
DANGER
Draining and filtering of oil must be accomplished with care to avoid the possibility
of a serious burn. The oil to be filtered is at or near 350°F (177°C). Ensure all hoses
are connected properly and drain handles are in their proper position before
operating any switches or valves. Wear all appropriate safety equipment when
draining and filtering oil.
DANGER
Allow oil to cool to 100°F (38°C) before draining into an appropriate container for
disposal.
DANGER
Do not drain more than one frypot at a time into the built-in filtration unit to avoid
overflow and spillage of hot oil.
DANGER
When draining oil into a disposal unit or portable filter unit, do not fill above the
maximum fill line located on the container.
If your fryer is not equipped with a built-in filtration system, the oil must be drained into another
suitable container. (For safe, convenient draining and disposal of used oil, Frymaster recommends
using the McDonald’s Shortening Disposal Unit (MSDU). The MSDU is available through your
local distributor.)
1. Turn the fryer power switch to the OFF position. Screw the drainpipe (provided with your fryer)
into the drain valve. Make sure the drainpipe is firmly screwed into the drain valve and that the
opening is pointing down.
