GENERAL INSTALLATION INSTRUCTIONS
This unit has been inspected and tested at the factory prior to shipment.
Unpack the unit and remove all packing materials. Place on a flat horizontal surface at the desired location.
!
!
CAUTION: Do not use ordinary steel wool as any particles left on the surface will rust.
NEVER USE a wire brush, steel or abrasive scouring pads (except stainless), scraper, file or other steel 
tools. Surfaces which are marred collect dirt more rapidly and become more difficult to clean. Marring also 
increases the possibility of corrosive attack.
NEVER use any corrosive cleaner. Use only cleaners approved for stainless steel.
NEVER use cleaning solvents with a hydrocarbon base.
