ForYour Safety do not store or use gasoline or other flammable vapors and liquids in

!the vicinity of this or any other appliance!

1.POST IN A PROMINENT LOCATION instructions to be followed in the event the user smells gas.This information can be obtained by consulting your local gas supplier.

2.Keep the appliance and surrounding area free and clear from combustible materials:

For CF-400G allow a minimum clearance from combustible oil construction of 4" (10.2cm) from bottom, side and back of the Fryer.

3.Do not obstruct the flow of combustion and ventilation of air.

4.Please retain this manual for future reference.

5.Please note wiring diagrams for this appliance are located in the rear of the manual. Ensure the wiring diagram which you consult corresponds to the model being operated.

6.The installation must conform with local codes or, in the absence of local codes, with National Fuel Gas Code ANSI Z223.1 - 1988. When in Canada, installation must be in accordance with CN 1-B149.1 or .2 . Installation must also conform with ANSI/NFPA 96.

7.The Fryer and its individual shutoff valve must be disconnected from the gas piping system during any pressure testing of that system at test pressure in excess of 1/4 psig (3.45 kPa).

8.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 1/4 psig (3.45 kPa), (14" water column).

CAUTION

!The flue gases of this appliance must be vented to the outside in accordance with National Fuel Gas Code, ANSI Z223.1-1988 and terminate in a UL listed outside vent terminal. When in Canada reference CANI-B149.1 or .2 “Installation Codes for Gas Burning Appliances and Equipment”.

Installation

1 - 2 Removal of Fryer from Crate

Your Giles Fryer may arrive enclosed by a wooden crate. If your unit arrived uncrated, go to Section 1-3. The Fryer is secured to a wooden platform by means of high-tensile strength strapping.

1.Carefully cut and remove the plastic shipping wrap and the strapping mentioned above.

2.Use pliers to loosen wire hooks which secure the wooden crate around the fryer. Remove the wooden crate.

3.Carefully remove the fryer from the shipping platform. Your new fryer is extremely heavy and great care should be taken in lifting or moving the unit to prevent personal injury or equipment damage.

1 - 3 Ventilation of Fryer

Your new Giles Gas Fryer has been designed for operation beneath a traditional exhaust hood. We strongly recommend you consult a professional ventilation or heating and air conditioning

company for assistance in designing a hood for an exhaust system.

IMPORTANT NOTE

Guidelines for proper ventilation system requirements may differ. Always consult with local authorities to ensure compliance.

1 - 4 Electrical Requirements

!WARNING

Fryers must be adequately and properly grounded. Improper grounding may result in electrical shock. Always refer to your local electrical code to ensure proper grounding of this or any other electrical equipment. Always consult with an electrician or other qualified service person to ensure breakers and wiring are of sufficient rating and gauge for the equipment being operated.

Giles Fryers are available from the factory wired for 120, 208 or 240 volts, and single phase only, 50/60HZ. service and set for either Natural or LP Gas. Check the rating plate on the door of the fryer to determine the correct power supply and fuel type.

Operating Instructions

2 Operating Instructions

For your safety, please observe the following precautions when operating your Giles Fryer:

1.Ensure the fry kettle is positioned in a secure, safe location with the casters in the locked position. A restraining device attachment ring is located on the lower right hand side of the Fryer.

2.Due to the high temperature of shortening in your fryer during cooking, it is extremely important the user exercise caution in operating this equipment to avoid personal injury.

3.Never move a fryer that contains hot oil! To avoid hazards associated with moving a fryer with liquid in the vessel, always allow adequate time for the liquid to cool.

4.If for any reason it becomes necessary to disconnect the fryer’s restraining device, ensure the restraining device is reconnected and the Fryer is returned to its original installed position.

5.Make sure all electrical and gas specifications have been met and the unit is grounded (see wiring diagram in Section 10).

6.In the event of power failure, DO NOT try to operate the unit.

Lighting and Shut-Down Instructions

1.Open the Main Gas Valve, turn Power Switch on.

2.Set the Thermostat to the desired temperature. (Giles Gas Fryers are provided with an automatic direct ignition system which eliminates the need for a pilot light).

3.In the event the burner does not ignite, a beeper will sound. Wait 5 minutes before attempting to restart the Fryer.

4.To RESTART, switch the Fryer’s main Power Switch to the “OFF” position. Return the Main Power Switch to the “ON” position and set the desired temperature.

5.To SHUT-DOWN the Fryer, turn the thermostat and the Fryer’s Main Power Switch to the “OFF” position, then CLOSE the Gas Supply Valve.

3 Fryer Components andTheir Functions

The following section is designed to introduce you to the controls used in operating this equipment.

!	DO NOT attempt operation of this unit until you have located each control discussed and fully
	understand their intended function. Failure to do so may result in improper operation resulting in
	equipment damage or personal injury to the operator.

Cooking Computer Control Panel Components andTheir Functions

ITEM		DESCRIPTION	FUNCTION
1.	Fig. 1	Power Switch	The Power Switch is a two-position switch.
			Move the switch upward to the “ON” position
			for operation.
2.	Fig. 1	Selector Switch	The Selector Switch is a three-position switch which is
			used to select either the cook, off or filter mode of
			operation. The fryer’s Heat Exchanger will only operate
			in the “COOK” position. The switch should be placed
			in the “FILTER” position to filter the shortening which
			will allow the pump to operate.
3. Fig. 1		Cooking computer	The Cooking Computer is used to select oil tempera-
			tures, cooking times and basket lift operations.
			Programming of the cooking computer is covered later

Fryer Components and Their Functions

3 - 2 Lower Cabinet Area
ITEM		DESCRIPTION	FUNCTION
1.	Fig. 2	Filter Pan Hold-Down	The Hold-Down Bracket is contained in the filter pan
		Bracket and Latches	and serves to ensure the filter paper is held tightly
			in place by means of the four locking latches. The
			fryer’s filtering action will be reduced or eliminated if
			these latches are not properly secured.
2.	Fig. 2	T-Handle/Drain Valve	Turning this T-Handle counter-clockwise allows shorten-
			ing to drain from the frying vessel into the filter pan.
			Open the valve slowly to avoid burns from
			splashing of hot oil. Always ensure the valve is closed
			prior to adding shortening. Your fryer will not operate
			if this DrainValve is not completely closed. (i.e.,
			clockwise)
3.	Fig. 2	Drain Valve Pipe-Drain	This Pipe-Drain attaches to the Drain Valve and helps
			to minimize splashing of hot oil when the fry-kettle is
			filtered or drained. The Pipe-Drain must be removed
			before sliding the filter pan out of the fryer. Always
			use insulated gloves to remove this hand tightened
			pipe.
4.	Fig. 2	Quick Disconnect	This Quick-Disconnect Fitting is used in conjunction
		Oil Discharge Wand	with the oil discharge wand to remove oil from the
			fryer that is to be discharged.
5.	Fig. 2	Diverter Valve	The Diverter Valve may be identified by its colored
			lever-type handle. During a normal operation, it should
			be positioned so it points outward toward the
			operator. For removal of oil with the discharge hose
			connected, the diverter valve handle should be turned
			inward and counter-clockwise. After removal of oil for
			discard it should be returned to its normal position
			pointing toward the operator. Details of the oil
			procedure are covered in the operations section of
			this manual.
6.	Fig. 2	Quick Disconnect For filter Pan	This Quick Disconnect fitting serves to connect the
			hose from the filter pan to the fryer’s oil return lines.

The hose must be disconnected at this fitting prior to sliding the filter pan outward for cleaning or removal. The fitting is operated by pushing upward on the insulating ring and exerting downward pressure on the connecting end of the hose. For reconnection, push upward on the insulating ring while inserting the hose. Release the insulating ring when the hose fitting is fully inserted to lock it in position.
