Introduction
Safe Work Practices
Do Not Store Or Use Anything Flammable Near
The Fryer
Your pressure fryer is powered by either natural gas or LP gas. Do not
store or use gasoline or any flammable liquids or vapors near this or any
other appliance. Flammable materials will burn easily. Letting any
flammable liquid or vapor get too close to the fryer could cause an
explosion or fire. Serious injury could result. Examples of flammables that
you should not store near the fryer are gasoline, paint, thinners or
removers, gas tanks, and cleaning materials.
Use Gas Safely-- Avoid Danger
Gas can be a dangerous fuel if not handled safely.
Make sure to ventilate the fryer properly. If the fryer is not properly
ventilated, carbon monoxide can be released around the fryer.
Asphyxiation or suffocation can occur if gas is not ventilated properly.
Before using this appliance for the first time, contact your local gas supplier
for instructions about what to do if you smell gas. Post those instructions
somewhere near the fryer, so that everyone who uses or works near the
fryer knows what to do if they smell gas.
Beware of High Voltage
This equipment uses high voltage. Serious injury can occur if you or any
untrained or unauthorized person installs, services, or repairs this
equipment. Always Use an Authorized Service agent to Service Your
Equipment.
Use the Fryer On Noncombustible Floors Only
Make sure your floor is noncombustible. Do not operate your fryer on floors
that are wood, carpeted or have rubber mats. Placing your fryer on a
combustible floor could cause a fire. Serious injury could result. Examples
of noncombustible floors where you can safely place your fryer are
concrete, tile, and ceramic.
Keep The Area Around Your Fryer Uncluttered
Make sure to keep the area around your fryer clear of any obstacles.
Serious injury can occur if you trip or fall near the fryer. You could be
burned by hot shortening that splashes out of the fryer or by falling against
the hot metal of the fryer.

Keep The Floor Around Your Fryer Clean Of
Shortening
Make sure to keep the floor around your fryer clean of shortening and
other liquids. Serious injury can occur if you slip near your fryer. You could
be burned by hot shortening that splashes out of the fryer or by falling
against the hot metal of the fryer.
Keep The Lid Closed When The Fryer Is Not In
Use
Hot shortening can splash if someone moves the fryer or bumps into it.
Serious injury can occur if hot shortening splashes out of the fryer.
Do not lean, sit or stand on the fryer or perform any maintenance or
cleaning duties while the fryer or the shortening is hot. You could be
burned.
Keep The Casters Locked
To avoid spilling shortening, keep the casters locked. If any shortening
spills near your fryer, clean it up immediately.
Do Not Overfill The Fryer With Shortening
Hot shortening and steam may escape and burn you if you put too much
shortening in the fryer. Fill the fryer to approximately one inch below the fill
marks that are inside the fryer pot. Heat the shortening. If needed, carefully
add more shortening to bring the level to the fill marks.
Do Not Let Any Water Get Into The Fryer
Always remove excess moisture from food before placing it into the fryer
basket. Water will cause the hot shortening to spatter. You could be
burned.
Do Not Overload The Basket With Food
Hot shortening and steam may escape and burn you if you place too much
food in the basket.

Safety Pop Valve Procedure
The safety pop valve should be blown under pressure periodically to prevent the seat from sticking.
Failure to use the insulated mitts will result in injury. Always use the insulated mitts when
handling the arm on the safety valve.
1. After the pressure is up during a cooking cycle, use the insulated glove to lift the arm on the edge of the
safety valve and let some steam escape. This will clean the valve.
2. Release the lever on the valve, and let it slam shut to seal the valve.
11
Gas Pressure Fryer
Maintenance
Filtering Procedure
Breaded foods require frequent filtering. An excess amount of breading left in the fryer pot will reduce the life of
the shortening. We recommend the shortening be filtered after every three frying cycle loads. When the
shortening starts to show signs of foaming and has a bad taste, do not use it. The fryer pot should be cleaned
before refilling with new shortening. Best results for filtering are obtained while the shortening is hot. You should
filter at the end of every business day. You should also remove and drain the condensation pan daily.
Always wear appropriate personal protection equipment during the filtering process to
guard against possible injury from hot oil.
If the pump motor automatically shuts off while filtering, place the FILTER/OFF/FRY
switch in the OFF position, wait 15 minutes, press the pump motor reset button, then
follow the appropriate refill procedure below.
LGF-F and LGF-FC
1. Set the FILTER/OFF/FRY switch to OFF.
2. Remove the fryer basket.

IMPORTANT: Make certain the vat cover is properly positioned underneath the drain valve. Also
make certain the filter vat and filter screen is under the main drain valve before starting the filtering
process.
4. Move the DRAIN handle slowly to the OPEN position so that the shortening starts to flow evenly. This
is to prevent excessive splashing of hot shortening.
5. When the pot is empty, place the DRAIN handle in the CLOSED position.
