E.Fire Extinguishing Systems

There are two basic types of ventilator fire extinguishing systems in use today:

Wet Chemical and Water Mist. Wet Chemical Systems may be all or partially factory installed [by the Fire System Manufacturer]; final hook up and certification at job site is done by the Fire System Manufacturer's local representative. These systems must be periodially inspected, and critical parts replaced. It is suggested that a service contract be purchased from the local representative. For further details refer to the manufacturer's technical manual.

AVTEC manufactures and installs a water mist fire extinguishing system, "MIST-A-FIRE", that connects to the building fire sprinkler system [must be "wet" type system]. Final connect of this system must be done in the field by the sprinkler contractor or authorized plumber. A certification/inspection report is done by an authorized AVTEC representative. Periodic inspection is generally required, but replacement of parts and periodic maintenance is virtually eliminated. For further details, refer to the AVTEC MIST-A-FIRE Installation and Operating Technical Manual.

II. INSTALLING THE VENTILATOR

The ventilator is supplied with brackets to facilitate the attachment of hanger rods to the vent. Hanger rods should be attached to all brackets to ensure proper support.

A.Ascertain that the ceiling/roof structure is strong enough to support the weight of the hood and support system. The approximate weight of the hood is shown below:

45 lbs/linear ft. for hoods w/o AMU plenums.

55 lbs/linear ft. for hoods w/AMU plenums.

125 lbs for fire control cabinet.

B.Carefully uncrate the hood so as not to dent or scratch the outer surface.

C.Position the hood on the floor in approximately its final installed location.

D.Use 1/2" threaded rods to hang the hood. The hanger rods should be approximately 1/2" closer to the wall at the structural attachment location than at the top of the hood. [see fig. #4] This ensures that the hood is held tightly against the wall.

Note! Do not remove Support Brace until Ventilator installation is complete. Upon completion of installation, dispose of Support Brace and replace the Acorn Nuts to their original locations.

2

Fig 4

E.The hood should be hung so that the bottom of the hood is 6'-6" above the finished floor unless otherwise specified. Carefully lift the hood into position being certain to avoid scratching the finished surfaces. Install 1/2" threaded rod from each bracket and the structural support. Secure rods with heavy duty nuts. [see fig. #5] Be sure that the hood is level.

Fig 5

Tower Interface Detail

Place trim collar on tower. Position tower under hood. Fully tighten trim collar retainer hardware after tower and hood are aligned properly. See fig. A, B, and C (next page).

F.The entire exhaust duct system must be continuously welded. This includes the connection to the duct collar and the roof curb. All welds must be liquid tight.

NOTE: Welds must not impede operation of damper.

G.Connect the lights to the circuit breaker panel through the light switch. All connections should be in compliance with NFPA 70, National Electric Code [NEC].

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.

III.CONTROL PANEL [if provided]

Control panels are provided with all auto wash type ventilators [Models AW- ] and are optional with the baffle filter type [AF- ] and modular grease extractor type [AX- ]. Control panels with Models AFand AXdo not have the auto wash plumbing assembly compartments. Any control panel may be provided with a integral MIST-A- FIRE Extinguishing System alarm panel and sprinkler assembly piping; refer to the MIST-A-FIRE technical manual.

A.Wall Attachment

Control panel dimensions and connection detail are shown on the enclosed shop drawing. Panels may be surface mounted, partially recessed or fully recessed as shown on fig. 6.

1.Surface Mounted

Drill four [4] holes in ventilator plumbing compartment as required. Be careful not to damage any components. Avoid drilling into electrical compartments. Bolt to wall with anchor bolts or other acceptable means. Weight of control panel varies from 90 lbs. to 200 lbs.

2.Recessed

Cut hole in wall 1/2" greater than O/A dimensions of control box [shown on shop drawing]. Spacers or support angles may be necessary to provide proper support. It is recommended that panel be bolted to wall similar to method used for surface mounted above.

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.Terminals No. 1 and No. 2 are for the 120vac Power Supply. Terminal No. 1 is Hot and Terminal No. 2 is Neutral.

3.Terminals No. 3 and No. 4 are 120vac power for the Water Solenoid and Detergent Pump. These terminals are "hot" whenever the Water Wash Solenoid and the Detergent Pump is scheduled to be "ON" or when there is a fire condition. Terminal No. 5 provides power for a pump/prime switch with a momentary closed/normally open contact. This switch is helpful in checking the performance of the pump as well as in priming the pump.

B.Programmable Automatic Wash Sequence

[PAWS] Control Panel

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.

2.Terminal Block #1 [TB-1] has three [3] terminals and is located on the right-hand side of the Input/Output [I/O] Board. Terminal #1 [uppermost] is for the Hot lead of the power supply and is protected by a fuse located within the panel. Terminal #2 [center] is for the Neutral lead of the power supply. Terminal #3 [lowermost] is used to ground the Input/Output Board to the Control Panel Housing.

Terminal No. 4 is Hot and Terminals No. 2 & 3 are Neutral.

3.Terminals No. 3 and No. 6 carry 120vac whenever the fans are scheduled to be ON. They are used to activate the fan contactor[s]. In the event of a fire situation, power is removed from Terminal 5 which provides power for Terminal No. 6. Terminal No. 6 is the Hot lead and Terminal No. 3 is Neutral.

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. It will not be present on P-10-__ or P- 15-__ Control Panels. The first pair of terminals are for wash valve solenoid number four. The second pair of terminals are for the number five wash valve solenoid. The third pair of terminals are for the number six wash valve solenoid.

6.Terminal Block #4 [TB-4] has three [3] pairs of terminals. It will not be present on P-10-__ or P- 15-__ Control Panels. The first pair of terminals are for the number seven wash valve solenoid. The second pair of terminals are for the number eight wash valve solenoid.

7.Terminal Block #5 [TB-5] has three [3] pairs of terminals. The first pair provides power for the detergent pump. The second pair provides power for the PAWS Alarm/Trouble horn. [The third pair provides power for the vent fan contactors. [see figs. #8a & 8b]

Note that the maximum output is one-and-one- half [1-1/2] amperes. If the total inrush current for all contactors will exceed this limit, an intermediate relay must be used.

8.Terminal Block #9 [TB-9] has three [3] pairs of terminals and is located at the lower left corner of the Input/Output Board. The first pair of terminals are for connection to the optional supervised shut-off valve. If the panel is not equipped with this option, a jumper wire must be installed. The second pair of terminals are for connection to the Manual Fire Switch. The third pair of terminals are for connection to the automatic fire switch contacts terminals are for connection to the automatic fire switch contacts.

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.
