ELECTRICAL CONNECTION

WARNING Electrical Grounding Instructions:

This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazards and should be plugged directly into a properly grounded three-prong receptacle.
Do not cut or remove the grounding prong from this plug. Fryer must be electrically grounded under local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.2, as applicable.
The electrical diagram is located on the inside of the door.

GAS CONNECTION

All gas supply connections and any pipe joint compound must be resistant to the action of propane gases.
The gas inlet is located on the lower rear of the fryer. Codes require that a gas shutoff valve be installed in the gas line ahead of the fryer.
The gas supply line must be at least the equivalent of ½” (12.7 mm) iron pipe for single units and 1-1/4” (31.75 mm) for batteries. If using the optional quick-disconnect flex hose, ¾” (19 mm) iron pipe for single units and 1-1/4” (31.75 cm) iron pipe for batteries.
Make sure the pipes are clean and free of obstructions, dirt, and piping compounds.
A battery requires one or two connections of appropriate size for the gas requirement.
Before lighting, check all joints in the gas supply line for leaks.
Use soap and water solution. Do not use an open flame.
After the piping has been checked for leaks, fully purge gas pipes to remove air.

GAS PRESSURES (ALL MODELS):

The gas measured exiting the gas valve should be set at 3.5” W.C. (Water Column) (0.87 kPa) for natural gas and 10” W.C. (2.49 kPa) for propane gas.
The supply pressure should be 7-9” W.C. for natural gas and 11-12” W.C. for propane gas. If incoming pressure exceeds 14” WC (½ psig -3.45 kPa), a step-down pressure regulator must be installed.

TESTING THE GAS SUPPLY PIPING SYSTEM:

When test pressures exceed ½ psig (3.45 kPa), the fryer and its shutoff valve must be disconnected from the gas supply piping system.
When test pressures are ½ psig (3.45 kPa) or less, the fryer must be isolated from the gas supply piping system by closing its shutoff valve.

Fryers with Casters:

Separate instructions for installing casters are included with the casters:
The installation shall be made with a connector that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69, CAN/CGA-6.16, and a quick-disconnect device that complies with the Standard for Quick-Disconnect Devices for Use with Gas Fuel, ANSI z21.41.CSA 6.9 or Quick-Disconnect Devices for Use with Gas Fuel.
When installing a quick disconnect you must also install a means for limiting the movement of the fryer.
This device will prevent the gas line or quick disconnect from being strained.
The restraining device should be attached to the cutout on the back panel. See illustration for location.

- Do not bring water to a boil. Fryer boilover can result.
Use the tank brush; to clean the sides, bottom, and heat exchanger tubes.
Unthread the Boil Out By-Pass™ drain plug and thread in the B oil Out By-Pass™ extension tube as shown in Fig. 6. The larger thread end screws into the back of the drain manifold as shown in the cutaway side view in Fig. 7.
Do not allow water to run through the motor/pump. Drain the boil-out solution into a bucket or place a high-temperature rated water hose on the end of the drain extension allowing the other end to flow into a floor drain.
Close the drain valve and refill the tank with water. Add 1 cup (1/4 L) of vinegar to neutralize the alkaline left by the cleaner. The solution level must be between the MIN and MAX levels on the fryer tank. Press the START(V) button on the solid-state knob control (A), to allow the solution to heat up. Allow the solution to stand for a few minutes.
Drain the tank by repeating step 7. Rinse thoroughly with clear, hot water. All traces of cleaner must be removed. Dry the tank thoroughly.
Close the drain valve and add a shortening.

THERMAL OVERLOAD PROTECTION BUTTON:

The motor/pump supplied with the filter system has a thermal overload protection circuit that senses when excess heat occurs. This can occur due to filtering for long periods or under heavy load before discarding debris buildup.
If the thermal overload protection is tripped, wait 5 minutes and then reset the motor by pushing the red button. The arrow in Figure 8 shows the location of the reset button; located on the right side of the motor/pump.
The pump may start immediately when the reset button is pushed and begin circulating hot oil.

MAINTENANCE

Hot oil and hot parts can cause burns. Use care when operating, cleaning, and servicing the fryer.
Spilling hot fryer compound can cause severe burns. Do not move the fryer without draining all frying compounds from the tank.
Disconnect the power supply to the fryer before servicing.
