Hussmann Medium Temperature Self Contained Specialty Horizontal Merchandiser SHM-3

• Fluorescent lamps should not be allowed to run to failure. If a re-lamp schedule is not in place, the tubes should be inspected for signs of degradation (blackened ends). Degraded or failed tubes should be replaced.

• Allowing severly degraded lamps to operate may cause a ballast failure or could expose the lamp holder to excessive heat. Replacing degraded bulbs is more cost effective than replacing ballast and lamp-holders.

• Traditional re-lamp programs are 18-to-24 month intervals. In the absence of a re-lamp program, a yearly inspection of the lighting system is recommended.

1. Inspect all lamp sockets and plug-receptacle connections for signs of arching. Replace any component that shows signs of arching.

2. Make sure all unused receptacles have their close-off covers securely installed.

3. Make sure proper cleaning procedures are followed. Lights and fans MUST be turned off when a case is cleaned and MUST be allowed to dry before turning power back on.

4. Do not use a pressure nozzle to clean inside of case.;

WARNING! SHUT FANS OFF DURING CLEANING PROCESS.

NEVER USE SHARP OBJECTS AROUND COILS.

Use a soft brush or vacuum brush to clean debris from coils. Do not puncture coils!

Do not bend fins. Contact an authorized service technician if a coil is punctured, cracked, or otherwise damaged.

Is there ICE in or on the coil?

ICE in or on the coil indicates the refrigeration and defrost cycle is not operating properly. Contact an authorized service technician to determine the cause of icing, and to make adjustments as necessary.

To maintain product integrity, move all product to a cooler until the unit has returned to normal operating temperatures.

• 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.

• 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.
