MAINTENANCE
Hood
Inspect the grease extractors each day for grease deposits, clean if necessary. Check the grease
container every day and empty. Wipe the interior/exterior of the hood daily, if possible, to
remove deposits or accumulations of grease. Periodically clean the interior of hood and light
fixtures with a mild detergent as necessary.
Scratches on the stainless-steel hood can be removed with an abrasive pad (e.g. Scotch-Brite) or
similar cloth, being extremely careful to always rub in the direction of the metal grain.
After removing any scratches or imperfections, clean the entire hood with a stainless-steel polish
(e.g. Shiela-Shine). Once polish has been applied, remove excess with a dry cloth.
Caution: Do not use steel wool pads, scrapers, etc. to clean stainless-steel surfaces. Do not use
chlorine or chlorine based substances, acids, or chloride based substances on or around the
hood. Vapors from these substances can cause corrosion on stainless steel.
Clean exhaust duct quarterly to prevent grease accumulation.
Notice:
If a kitchen ventilation hood is cleaned with pressure-washer or steam cleaner, the silicone
sealant will be removed from the sealed seams. Standard daily cleaning over time will loosen the
seal and the silicone will be removed from the sealed seams.
The sealant may be replaced, after a thorough cleaning and de-greasing, with a food grade high
temperature silicone. Clean grease extractors daily in a dishwasher or other containers with a mild
detergent in warm/hot water. Never use harsh or abrasive cleaners on stainless steel.
Fans
Check cleanliness of supply fan intake filters every two weeks, for the first month, to establish a
cleaning schedule. To clean filters, remove supply fan lid, and filters. Flush filters with warm soapy
water and recoat with a filter coat adhesive. Reinstall filters and lid.
Check tension of fan drive belts (exhaust and supply) upon initial installation, and again after a
period of two weeks of operation. Belts tend to stretch during the initial stages of service. Inspect
condition and tension of belts monthly there after. Properly adjusted belt tension will allow
approximately 1/2” deflection on each side of the belt, midway between the pulley centers with
slight finger pressure. Overly tightened belts will cause wear, motor overloading, bearing wear
and noise. Loose belts will cause belt wear, pulley wear, and poor fan performance.
A monthly cleaning of exhaust fan wheel and interior of housing is required. Heavy grease build-
up is a fire hazard and can also cause wheels to be unbalanced. This leads to bearing wear,
undue noise, and poor fan performance.
Oil and/or grease all motors and bearing every six months or as conditions dictate. At least
once a year, check motor and fan shafts. Clean and check tightness & alignment.
At least every six months, all electrical connections should be inspected and checked for tightness.
