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 instructio somewhere near the fryer, so that everyone who uses or works near the fryer knows what to do if they smell gas.
ns about what to do if you smell gas. Post those instructions
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.

Gas Pressure Fryer Introduction
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.

Wear Safe Clothing Appropriate To Your Job
Always wear your insulated mitts when handling the fryer basket or touch any hot metal surfaces. You received a pair of insulated mitts with your fryer. If you lose or damage your mitts, you can buy new ones at your local restaurant equipment supply store or from your local BKI Distributor.
Always wear non-skid shoes when working around the fryer or any other equipment that uses shortening. Never wear loose clothing such as neckties or scarves while operating your fryer. Keep loose hair tied back or in a hair net while operating your fryer.
Always wear appropriate personal protection equipment during the filtering process to guard against possible injury from hot oil.
Always wear appropriate personal protection equipment during the boil-out process to guard against possible injury from hot cleaning solution.
Never Loosen The Spin Handle Until The Pressure Gauge Is At Zero
Steam may escape suddenly if you loosen the spin handle before the gauge is at zero. If steam escapes suddenly, you could be burned.
After the pressure gauge is at zero, wait 5 seconds. Then loosen the spin handle slowly to open the lid of the fryer. By doing this, the steam will escape slowly and you will not be burned.
Seal The Safety Valve Properly
To seal the safety valve, lift the arm on the side of the valve. Then release it. The valve should snap closed. Hot steam can escape from the valve and you could be burned if you do not seal the valve properly.

Gas Pressure Fryer Installation

Installation

Inspection for Shipping Damage

It is the owners’ responsibility to file all freight claims with the delivering truck line. Inspect all cartons and crates for damage as soon as they arrive. If damage to cartons or crates is found, or if a shortage is found, note this on the bill of lading (all copies) prior to signing.
If damage is found when the equipment is opened, immediately call the delivering truck line and follow up the call with a written report indicating concealed damage to your shipment. Ask for an immediate inspection of your concealed damage item. Packaging material MUST be retained to show the inspector from the truck line.

Preparation

There are several things the installer must know before installing the fryer. These are listed below:
The fryer installation must conform with city or county standards for gas appliances and gas piping. If your
area does not have local codes, consult the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or the
Natural Gas and Propane Installation Code, CSA B149.1. In Europe, city and country codes are enforced.
Do not attempt to test the gas pressure of your fryer. Pressure testing should be done only by an authorized Service Agent.
During any pressure testing of the gas supply system, the fryer must be protected. The fryer and its
individual shutoff valve must be disconnected from the gas supply piping system during any pressure
testing of that system at test pressures in excess of ½ psi (3.5 kPa). The fryer must be isolated from the
gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the
gas supply piping system at test pressures equal to or less than ½ psi (3.5 kPa).
The fryer must be electrically grounded to conform with the local code of your city or county. If your area
does not have local codes, consult the latest version of the National Electrical Code ANSI/NFPA 70, or
the Canadian Electrical Code, CSA C22.2. In EUROPE, city and country codes are enforced.
A schematic diagram of the unit is glued to the back of either the left or right side panel.  The Authorized Service Agent that installs your fryer must connect the cord set at the rear of the fryer to
an electrical source with a voltage matching that stamped on the name and rating tag. Refer to the wiring
diagrams in this manual.
Make sure a connector is used that complies with the Standard for Connectors for Movable Gas
Appliances, ANSI Z21.69 • CSA 6.16.
Make sure a quick-disconnect device is used that complies with the Standard for Quick-Disconnect
Devices for Use With Gas Fuel, ANSI Z21.41 • CSA 6.9.
In Europe, the installer must supply the gas supply connector.  Make sure a restraining device is used that complies with the Standard for Commercial Gas Ranges,
ANSI Z83.11/CGA 1.8 (such as BKI part number FT0279) to guard against transmission of strain to the
connector.
