TYPES OF SYSTEMS This manual covers three [3] of the basic types of systems offered by AVTEC - Baffle Filter [AF], Modular Grease Extractor [AX] and Auto Wash Down [AW]. A.Baffle Filter [AF Series] [See fig. #1] Model AF ventilators are listed by Underwriters Laboratories Inc.
integral water wash system cleans the inside of the grease extraction chamber either by manual activation of the Wash Start button or by a programmable timer. The duration of the wash is electrically controlled. The wash system is also activated by an electrical thermostat or a manual switch in the event of a fire condition. A surface fire extinguishing system is required and may be factory supplied. Wet Chemical and Water Mist.
H. Install bulbs in the light fixture[s]. I.Install the grease filters [AF] or modules [AX]. J.Install the grease receptacles [AF or AX] NOTE: A minimum of a three inch [3"] insulated fire barrier and air space must be maintained between the capture area skin of the ventilator and any combustible surface, including wall and ceiling. AVTEC ventilators normally have a 3" air space; insulation is added when specified. Fig 4 E.

1.Typical Field Connections for the PAWS Control Panel are shown on [figs. 10, 11, and 12]. Note that all options and connections may not be included on your system. IV. ELECTRICAL CONNECTIONS A.VCW Control Panel [Refer to fig. 7] 1.Typical field connection terminals for VCW Control Panel are shown in fig. 7. For custom features such as sequential wash, time delay, etc. refer to AVTEC shop drawing in back of this manual. 2.
4.Terminal Block #2 [TB-2] has three [3] pairs of terminals and is located at the upper right corner of the Input/Output Board. The first pair of terminals are for the number one wash valve solenoid. This will be the only wash output active in a P-10-__ or P-15-__ Control Panel. The second pair of terminals are for the number two wash valve solenoid. The third pair of terminals are for the number three wash valve solenoid. 5.Terminal Block #3 [TB-3] has three [3] pairs of terminals.
9.Terminal Block #11 [TB-11] has three [3] pairs of terminals. The first pair of terminals are low voltage connections for the detergent low level probe. The probe should be installed in the detergent container so that it does not protrude above the top of the detergent pump inlet strainer. [fig. #9] This is intended to prevent cavitation of the pump and will advise when the tank needs to be refilled. The probe rods may be cut to facilitate a neat and effective installation. Fig 9 10.

C.Dampers & Detectors [AW & optional AX Models] [Fig. 13] Terminal block in the damper housing is prewired to a junction box above. The wires are colorcoded; refer to field interconnection wiring diagram. [Refer to enclosed control panel wiring diagram]. Interconnection may be required between damper housings. C.Drain[s] The drain pipe is connected at one or both ends of the ventilator and run to an air gap assembly, hub & funnel or open floor drain to act as an anti-siphoning device.

VI. OPERATION A. VCW Control Panel [Refer to fig. 16] 1.Adjustment The component layout is shown below. The only adjustment necessary is for the auto wash timer relay. Refer to Sec. VII. G, page 18 for function explanation. Normally three minutes is used for ovens, steam equipment and light duty ranges, and five minutes is used for fryers, griddles, etc. A longer wash may be required for charbroilers. will continue to time down.
vac as long as the "START" Button is depressed. 4.Check all the dampers on the ventilator to verify that none of the dampers have been activated into the fire condition. 5.Check condition of solenoid for damage or debris. d.Once the "Start" Button is released, power[120vac] will be present at terminals No. 2 & No. 6. If no power is present after releasing start button verify that the fan contactor has been wired as shown on VCW Panel Electrical Schematic. d.
started and stopped manually or programmed or automatic operation. silenced by pressing the "VFC Horn Silence" switch, but the trouble condition will continue to be displayed. The fan will operate normally, hot water will not flow during the wash cycle and the display will continue to flash "PLENUM WASH AND FIRE CYCLES LOST". When the valve is opened, the alarm condition will automatically clear itself.
The PAWS Control Panel is equipped with an integral clock which can be used to automatically operate the fan and wash cycles. To set the time press "RETURN CLOCK" once. The display will read "SET DAY AND TIME SELECTED" and then change to "SET DAY AND TIME" as well as the day and time. Press "CHANGE CLEAR" and the day and time will begin to flash. Press "DAY+" and/or "DAY-" to set the correct day. Press "HOUR+" and/or "HOUR-" to set the correct hour. Note if "AM" or "PM" is displayed correctly.
"SAVE ENTER" to retain that time. Press "RETURN CLOCK" to return to Normal Display. "RETURN CLOCK" to return to Normal Display. If no key is pressed for thirty [30] seconds, the display will automatically return for Normal Display. d. Reviewing The Daily Event Schedule The Daily Event Schedule is a program which will automatically turn the fans on and off and/or initiate the PAWS up to four [4] times each day. Each day may be different from another or it may be programmed to stay off for the entire day.
PAWS Programming Keypad k. Diagnostic LED Indicators Because of the use of solid state relay circuits, a conventional voltmeter may not give reliable readings as regards to the operation of the various inputs and outputs. To aid in troubleshooting, diagnostic LED indicators have been built into the left-hand side of the Input/Output Board. They are shown below. h. Fan On During Recovery The operator can choose to have the fan on during PAWS recovery periods or remain off.

l. Detergent Pump and Tank Terminals No. 23 and 24 of AVTEC terminal strip supply 120vac power to the detergent pump during the Wash Cycle[s]. The pump does not run during the Fire Cycle nor when the detergent level is below the bottom of the probe. Detergent pumps are factory preset according to the chart in fig. no. 15. This is a generalized guide; settings may vary depending on water temperature and pressure, detergent type and concentration, grease load and PAWS duration. VII.
[Refer to fig. 21] Grease extractor modules are installed by sliding the top [narrow] part of the module into the upper retaining slot and then lowering the bottom part of the module into the grease trough slot. ventilator section to hold the front panel open. 2. Spray Nozzles Spray nozzles for hot water wash and cold water mist are protected from clogging by wye-strainers located in the plumbing enclosure.
F. After the temperature has dropped below 300oF, the damper can be reset and opened by pushing the damper reset arm toward the plenum until it latches. If the fusible link has melted, it must be replaced before the damper can be reset. An access plate is provided. To adjust air intake slot, turn nuts to loosen, move air adjustment baffles up or down until the desired slot opening is obtained, and tighten nuts. E. Fire Dampers 1.
plenum area which runs whenever the fans are ON. This com- plements the baffle system on Energy Aire Systems and does not replace the wash down feature. Water pressure should be between 30-40 psig flow. I. Lights 1. Surface Mounted - Incandescent To replace the bulb unscrew the globe. Fixture will accept bulbs up to a maximum of 100 watts. Screw the bulb into the socket and then proceed to screw the globe tightly in position.
Cable tension can be adjusted by moving the eye-bolts in and out to ensure that the damper is fully open. fig. 27 D. Grease Collection Receptacle Should be emptied at least once a day, and cleaned daily with a strong detergent. 2. Curtain Type [Refer to fig. 28] When make-up air is brought directly into the capture area a fire damper is required at the duct collar. The curtain damper is equipped with a 212°F fusible link [P/N AS LNK0006]. Fusible links shall be replaced at least annually per NFPA 96, 8-2.

CALCULATING AND RECORDING AIR MOVEMENT 1.) Cubic feet per minute or CFM'S is the total area multiplied by the average feet per minute. A: AREA CFM FPM B: CFM = AREA x AVG. FPM FPM = CFM ÷ AREA AREA = CFM ÷ FPM 2.) AREA is the length of the opening multiplied by the width in inches. Divide the total by 144 to get the total square feet (area). EXHAUST A: Filter Hoods - Area = *Square Feet x Quantity of Filters * 16 x 20 Filter = 1.75 Square Feet * 20 x 20 Filter = 2.
NOTE: AVTEC INDUSTRIES recognizes readings taken at the surface and not at the duct opening. Please refer to the Air Movement Recording Worksheet for proper location(s) to take readings. WARRANTYAVTEC INDUSTRIES INC.
