REMOTE PIPING
All remote piping must meet applicable local plumbing codes.
The panel must be installed with adequate protection to stop
the flow of detergent back into the potable water supply. This
may be accomplished, depending on the municipality, with a
vacuum breaker and check valve assembly or a back flow
preventor. SPRING AIR SYSTEMS will always prepipe the
detergent line into the main hot water outlet pipe in the
plumbing cabinet unless advised to do otherwise prior to
shipment.
IT IS IMPORTANT TO CHECK WITH LOCAL PLUMBING
INSPECTORS TO DETERMINE WHAT IS ACCEPTABLE
PRACTICE IN YOUR JURISDICTION.

CLEANING THE EXTERIOR
Normal soil can be removed with a mild detergent water mixture applied to a cloth.
To remove baked on grease, apply a cleanser to a damp cloth or sponge and rub on the metal in the direction of the
polishing lines. DO NOT RUB IN A CIRCULAR MOTION. Burnt deposits, which do not respond, can usually be removed
by rubbing the surface with SCOTCH-BRITE scouring pads or STAINLESS scouring pads. Do not use ordinary steel
wool. Heat tint can be removed by a vigorous scouring in the direction of the polish lines using SCOTCH-BRITE or
STAINLESS scouring pads in conjunction with powdered cleanser.
Once the wash cycle(s) are complete wipe of the interior surface of the ventilator canopy and the underside of the grease
trough and skirt.
During the wash cycle(s) condensation may form on these surfaces. The condensation will assist in cleaning off any
grease, dirt or lint, which may have built up during the daily operation.
