C.Dampers & Detectors [AW & optional AX Models] [Fig. 13]

Terminal block in the damper housing is pre- wired 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.

Fig. 13

D.Ventilator Lights

A 120vac supply circuit must be supplied thru a ventilator light switch to the ventilator. The light switch may be supplied by AVTEC in the control panel or on the hood. Interconnection may be required between light fixtures.

V.PLUMBING CONNECTIONS [AW Models] [Refer to fig. 14]

The connections listed below are shown on page 8.

A.Hot Water Wash

140ο hot water is needed to properly clean the extractor chamber. Supply is connected to the control panel inlet. Control panel outlet is connected to the ventilator inlet[s].

NOTE: A vacuum breaker and check valve must be installed at least 6" above the ventilator inlet to prevent back-up of detergent water into fresh water supply.

B.Cold Water Mist [Optional]

Cold water supply is connected to the control panel inlet. Control panel outlet is connected to the ventilator inlet[s].

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. An air gap assembly is recommended for the most sanitary and positive connection. The air gap should be the same size on the inlet end and one pipe size larger on the outlet to avoid splash over.

D. Field Joints

Interconnection between field joints on AW Hood attach with 2” elbows and expandable coupler. [Refer to fig. 11]

E.Detergent Pump and Tank

Detergent pump tubing [plastic, copper or stainless steel] must be provided from the detergent pump outlet to an injection point between the vacuum breaker/check valve and the ventilator inlet. For larger installations multiple pumps are used. Normally the detergent pump and tank are located in the control panel, and tubing from the detergent pump to the detergent tank is factory connected. In the application when the detergent pump and tank are located in a remote area, tubing is provided for connection from the pump to the tank.

Pumps may be pre-wired in control panel or Energy Distribution System, or located remotely. Detergent tank must always be located within 5 ft. of the pump.

F.Interconnecting

Depending on specifications, some ventilator sections may require interconnection of hot water, cold water or drains. See shop drawing in back of this manual for detail.
