Hussmann Q-Series Medium Temperature Self Contained Merchandiser Q1SSM4S

• Long life and satisfactory performance of any equipment is dependent upon the care it receives. To ensure long life, proper sanitation and minimum maintenance costs, these merchandisers should be thoroughly cleaned, all debris removed and the interiors washed down, weekly.

Exterior Surfaces • The exterior surfaces must be cleaned with a mild detergent and warm water to protect and maintain their attractive finish. Never use abrasive cleansers or scouring pads.

• The interior surfaces may be cleaned with most domestic detergents, ammonia based cleaners and sanitizing solutions with no harm to the surface. Self contained models empty into a limited capacity evaporation pan, which will overflow if excess water is used in cleaning.

•Abrasive cleansers and scouring pads, as these will mar the finish.

•Coarse paper towels on coated glass.

•Ammonia-based cleaners on acrylic parts.

Clean evaporator coil/s and fan blade/s. Do not use an acid base cleaner. Rinse off any cleaner residue.

Clean discharge air honeycombs or grilles. Do not use an acid base cleaner. Rinse off any cleaner residue.

Clean condenser coil/s and fan blade/s. Do not use an acid base Cleaner. Rinse off any cleaner residue.

Clean condensate drain pan and drain line.

Verify condensate drain lines are clear and functioning.

Record voltage reading at unit with unit off.

Record voltage reading with unit running.

Make sure all electrical connections, factory and field, are tight

Verify electrical connections at lamps are secure and dry

Check for and replace any frayed or chaffed wiring

CAUTION! Evaporation Pan is Hot! and poses risk of bodily injury – Always Wear gloves and protective eye wear when servicing.

Turn off evaporation pan heater, and allow pan to cool.

The condensate water outlet for self contained models empties into a limited capacity evaporation pan.

Debris or dirt accumulation inside the condensate evaporation pan or on the heater coil will reduce the pan’s evaporation capacity and cause premature heater failure. The evaporation pan waste water will overflow and spill onto the floor if the heater is not properly operating.

Remove accumulated debris from the evaporation pan.

Wipe down heater coil with a cloth and warm water.

Be sure to remove any dirt, debris or liquids from the heater coil.

Water introduced during cleaning will cause the evaporation pan to overflow.

CAUTION! DO NOT FLOOD! Use only enough water necessary to clean surface. Water must not drip down the case! Never use ammonia based cleansers, abrasive cleansers, or scouring pads.

Use non-abrasive cleaning materials, and always polish with grain of the steel.

Use warm water or add a mild detergent to the water and apply with a cloth.

Always wipe rails dry after wetting.

Use alkaline chlorinated or non-chlorine containing cleaners such as window cleaners and mild detergents.

Do not use cleaners containing salts as this may cause pitting and rusting of the stainless steel finish.
