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

Drill four 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 to 200 lbs.

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

The fan operation and wash sequence can be started and stopped manually or programmed for automatic operation.

4.Duct shall be constructed of 22 or 24 gauge steel. Insulated duct material should be used to eliminate frost and/or condensation.

5.Duct shall be sized to provide air velocities not exceeding 1200 FPM.

6.A volume control damper, provided in the duct just above the supply collar that

contains the UL listed re damper, should be properly set to supply CFM required.

7.If the hood is provided without the supply collar installed, it must be installed per the instructions provided on the collar.
