INSTALLATION INSTRUCTIONS

CAUTION:

This equipment is manufactured for the use on a particular type of gas and electrical voltage which is specified on the rating plate located on the inside of the door.

When your fryers arrive, look them over carefully noting any damage on the freight bill. If concealed damage is found after you have accepted the equipment, report it to the carrier immediately, as all claims must be filled within 15 days of the receipt of the shipment. Also, be sure to keep any packing materials as these will be necessary to make a claim.

Follow these installation instructions carefully. A proper installation is important for the operation of the fryers.

Note: It is recommended that the ventilation system be cleaned and maintained on a regular basis.

Quick Disconnect Gas Connection:

Units equipped with casters must be installed with connectors that comply with the standards for connectors for Movable Gas Appliances, ANSI Z21.69-1987, and Addenda Z21.69A-

1989. (CAN/CGA - 6.16 and CAN/CGA - 6.9.) This connection should include a quick disconnect device that complies with the Standard for Quick Disconnect Devices for use with Gas Fuel, ANSI Z21.41-1989. When installing a quick disconnect you must also install a means of limiting the movement of the fryer. This device will prevent the gas line or quick disconnect from being strained.

Fuel Supply Line Leak and Pressure Testing:

In the United States, all installations must conform to all local and state codes and well as the National Fuel Gas Code (ANSI 223.1 1992). In Canada, installations must be made in accordance to Canadian Standard CAN 1-B149.1 or .2 “Installation Codes for Gas Burning Appliances & Equipment.”

Electrically operated appliances must be electrically grounded in accordance with local codes; or in the absence of local codes, with the National Electric Code ANSI/NFPA No. 70-1996; in CANADA, with CSA C22-1 Canadian Electrical Code Part 1.

Ventilation:

A proper ventilation system is also an important part of the installation. For information on the construction and installation of ventilating hoods, please see “Standard for the Installation of Equipment for the Removal of Smoke and Grease Laden Vapors from Commercial Cooking Equipment”, N.F.P.A. No. 96-1987. Copies can be obtained by writing to the National Fire Protection Association, Battery March Park, Quincy, MA 02269.

The fuel supply system must be tested before the machine can be used. If the fuel line is going to be tested at a pressure greater than (>) 1/2 PSI (3.45 kPa), make sure that the unit is disconnected from the fuel line. If the fuel line is going to be tested at a pressure equal to or less than (≤) 1/2 PSI (3.45 kPa), the machine can be connected to the supply but the gas valve must be shut.

Clearances:

Minimum clearance of 6" (15cm) must be maintained from combustible construction on each side and the rear of the equipment. This equipment may be installed on combustible floors. Maintain a minimum of 24" (61cm) clearance in front of the fryer to provide for proper operation, maintenance and servicing.

NOTE: Do not block the area around the bottom or underneath the fryer. The air required to support the gas combustion is drawn from the underneath and sides of the fryer.

Leveling the fryers:

Leveling the fryers will help ensure proper opera-

tion. To level the fryers loosen the two set screws on the caster/leg stem. Rotate the collar of the caster/ leg to raise or lower the height of the unit. Tighten the set screws to lock the adjustment in place.

Filling the fryer with oil:

CAUTION:

Never operate this equipment empty. Always make sure there is the correct amount of shortening or in the case of cleaning, water in the fry tank before turning the unit ON.

It is very important to make sure the oil level is correct before attempting to heat shortening in your Pitco fryer.

Liquid shortening can be poured directly into the fry tank until the correct level has been reached. This is indicated by a line on the right or left hand sides of the inside of the fry tank. "C" is the level for Cold shortening and "H" is the level for Hot shortening.

For solid shortening, the shortening must be cut into small blocks about 1" (2.54 Cm) in size. These small blocks must be placed under and around the heat tubes.

Regular cleaning of this equipment, as well as the hood, is an important part of proper maintenance. Clean the fry tanks using the Boil Out procedure described in the operating manual.

A wiring diagram is located in the back of this manual and inside the fryers.

Retain this manual for future reference.

HOW DOES IT WORK?

The Advanced Gas Fryer will have certain reactions to what is happening, knowing what these reactions are and knowing what the machine is trying to do will enable us to diagnose most of the problems likely to be encountered.

Heating System

• Power to the machine is turned ON.

• The computer is supplied with 24VAC and, if the Drain Valve Handle is closed, the Proximity Switch will supply 24 VAC to the DVI (Drain Valve Interlock) Input at the computer. As soon as the computer is powered up it will show something on the display.

• Computer calls for heat.

• Full Tank - The Heat Demand Relay will energize, supplying the Blower, the Pilot Solenoid on the Gas Valve and the Ignition Control Modules with power. Both Ignition Control Modules supply power to the Spark Ignitors. At the same time one of the Ignition Control Modules supplies power to the Gas Cut Off Relay. The Gas Cut Off Relay energizes allowing the second Ignition Control Module to supply power to the normally open Pressure Switch. When the Blower comes up to speed, which should take a couple of seconds, the Pressure Switch will close allowing 24 VAC to the Main Solenoid of the Gas Valve. This will also supply the computer with a heat feedback signal. Since there are two burners in a full vat machine each of the Ignition Control Modules alternately sends a spark signal to the Ignitor and tests for a flame sense signal from the same Ignitor. When a flame sense signal is received it will cease to send the spark signal and continue to sense flame. If, after 10 seconds, a flame sense signal has not been established the Ignition Control Module will "Lock Out" and cease to run until reenergized.

• Split Vat - The same power that supplies the computer also supplies 24 VAC to the normally open Pressure Switch. When the computer energizes the Heat Demand Relay the Blower will be supplied with power and come up to speed. At this time the air pressure from the blower will close the Pressure Switch and allow 24 VAC to go to the second set of

contacts within the Heat Demand Relay. Since the Heat Demand Relay is now closed the Ignition Control Module and Hi Limit Switch will receive 24 VAC. If the Hi Limit Switch is NOT tripped it will allow 24 VAC to be supplied to the Pilot Solenoid of the Gas Valve. The Ignition Control Module supplies 24VAC to the Main Solenoid of the Gas valve. The Ignition Control Module alternately sends a spark signal to the Ignitor and tests for a flame sense signal from the same Ignitor. When a flame sense signal is received it will cease to send the spark signal and continue to sense flame. If, after 10 seconds, a flame sense signal has not been established the Ignition Control Module will "Lock Out" and cease to run until it re-energizes.

Hi - Limit System:

When the Hi Limit trips it causes the power to the Pilot Solenoid to stop and gas will cease to flow through the gas valve. This will cause a Lock Out condition and the burners will not light. The Hi Limit Switch should be manually reset by pressing the Power Switch to the OFF position and pressing it back to the ON position.

Filter System:

With the Filter Circuit Breaker in the ON position, opening the RED Return Valve Handle will cause the Pump On Relay to be energized and the pump will begin to operate. Closing the Return Valve Handle will de-energize the Relay and the Pump will stop running.

Heat Tape:

All Advanced fryers are equipped with Heat Tape which has an indicator light that will illuminate when the piping is up to operating temperature, do not attempt to pump unless the Filter Ready Light has illuminated.

COMPONENT TROUBLESHOOTING

Temperature Probe:

plied to the coil. When energizing, the relay Switching Contacts will close, thus connecting the Common and Normally Open terminals.

The resistance of the probe decreases as the temperature rises. The lower the temperature the greater the resistance change will be per degree of temperature change, as the temperature approaches the working range of the probe, the resistance change will slow and become more linear. If the probe is suspect, check its resistance and the oil/air temperature at which it was taken. Compare these values on the chart below.

TEMP RESISTANCE TEMP RESISTANCE

ºF Ohms Ω ºF Ohms Ω

60° 139055 Ω 330° 1192 Ω 80° 84644 Ω 335° 1123 Ω 100° 53146 Ω 340° 1058 Ω 120° 34328 Ω 345° 998 Ω 140° 22755 Ω 350° 942 Ω 160° 15446 Ω 355° 890 Ω 180° 10716 Ω 360° 841 Ω 200° 7586 Ω 365° 795 Ω 210° 6427 Ω 370° 752 Ω 220° 5470 Ω 375° 712 Ω 240° 4013 Ω 380° 675 Ω 260° 2991 Ω 385° 640 Ω 280° 2262 Ω 390° 607 Ω 300° 1734 Ω 395° 576 Ω 320° 1347 Ω 400° 547 Ω 325° 1267 Ω

If the probe returns an open circuit or 0 Ohms reading it should be replaced. If the resistance varies more than 20 Ohms from the above chart when being checked between 325-375°F (162ºC - 190ºC) the probe will give a false temperature reading on the computer and should be replaced. However, it will continue to operate at a slightly higher or lower temperature. Allow the oil to cool and check the probe resistance at a lower temperature. As can be seen from the chart a greater degree of offset can be allowed at a lower temperature.

Relays:

Hi Limits:

A Hi - Limit switch is a normally closed switch until the temperature at its probe reaches 435ºF ± 15° (225ºC ± 15º). In order to test this switch it will be necessary to bypass the Heat Demand Relay. This will cause the fryer to heat until the temperature of the oil reaches the necessary temperature to trip the Hi Limit.

WARNING

Do NOT leave the machine during this test. This test will cause the oil to heat past the normal operating temperature and can cause damage to the machine and its operator. Always use an external temperature probe to observe the oil tempersature during this procedure

In order to cause the oil to reach a temperature where the Hi Limit will trip it will be necessary to bypass the Heat Demand Relay. To do this, use a small jumper wire and join the Normally Open (Terminal #5) and Common (Terminal #3) terminals on the switch section of the relay

If the switch does not trip between the prescribed limits it is defective and should be replaced. Once tripped, the switch cannot be reset until the oil has cooled to approximately 400°F (204ºC). If the switch cannot be reset it is defective.

Drain Valve & Return Valve Switches:

These switches are magnetically operated Reed switches. When the Drain Valve handle is moved to the open position, the Actuator will move away from the switch causing the Reed switch to open. When the Drain Valve is closed the Reed switch will close. This switch can also be checked with an Ohm meter. The normal gap between the Actuator and the Sensor switch on the Drain Valve handle is 1/8" - 1/4" (3 6 mm).

Relays will energize when the correct voltage is sup-

Transformer:

Ignitors:

Transformers are multiple input voltage, 24 volt output voltage and can be checked by reading the input and output voltages.

Blower:

Check the voltage between the wires going to the Blower. If 120 VAC is found and the Blower is NOT turning it is defective.

Pressure Switch:

As the blower speed rises the amount of vacuum on the suction side of the pressure switch rises past approximately 1.3" WC (0.325 kPa) the Presssure Switch will close. When the vacuum falls below approximately 0.8" WC (0.2 kPa) the Pressure Switch will open. With the Blower running, check the IN and OUT voltage of the Switch. If 24VAC can be found on one side but NOT the other the Pressure Switch is defective.

When an Ignitor is supplied with power and does NOT spark the Spark Gap should be checked.The distance between the Ignitor and the Ground post should be approximately 1/8" ± 1/32".

If the Ignitor is sparking but the Burner does not light, check for a gas supply and make sure the Ignitor is located in the correct position as shown in the drawing.

Gas Valve:

The Knob should be in the ON position. Check for 24VAC between the terminals marked MV and MV/ PV and between PV and MV/PV. If voltage IS found between both of these connections and the Gas Valve does not open the Gas Valve is defective. If voltage is NOT present at both of the coils on the Gas Valve, troubleshoot and repair the machine until voltage IS present at both coils, retest the Gas Valve as previously described.

Ignition Control Modules:

When the Ignition Control Module is supplied with 24 VAC from the temperature control system at the TH terminal it will send a signal to the Ignitor which will begin to spark. At the same time the Ignition Control Module will also have a 24 VAC output signal on the MV terminal. The Ignition Control Module will cause the Ignitor to spark for 10 seconds and and then look for a flame sense signal, if it does not receive a flame sense within 10 seconds signal it will "Lock Out".
