Maintenance

Case Cleaning
To insure long life, proper sanitation and minimum maintenance
costs, the refrigerator should be thoroughly cleaned frequently.
SHUT OFF FAN BEFORE CLEANING: It can be unplugged within
the case, or shut off entire case at the source. The interior
bottom may be wiped with any domestic soap or detergent
based cleaners. Sanitizing solutions will not harm the interior
bottom,
WARNING! DO NOT USE WATER HOSES! A self contained case
empties into an evaporator pan that WILL OVERFLOW IF TOO
MUCH WATER IS INTRODUCED during cleaning
• USE WATER AND A MILD DETERGENT FOR THE EXTERIOR
ONLY
• Wipe interior with damp non abrasive cloth. Soap and
hot water are not enough to kill bacteria; a sanitizing
solution must be included with each cleaning process to
eliminate bacteria.
• Clean any visible debris surrounding or on top of the
drain location. The drain is located under the deck pans.
• DO NOT USE A CHLORINATED CLEANER ON ANY SUR‐
FACE.
• DO NOT USE ABRASIVES OR STEEL WOOL SCOURING
PADS (these will mar the finish)
• DO NOT USE A CLEANING OR SANITIZING SOLUTION
THAT HAS AN OIL BASE (these will dissolve the butyl
sealants) or an AMMONIA BASE (this will corrode the
copper components of the case)
Service
• Ensure front and rear intake panel vents remain clear
and clean of any debris to ensure optimal case perform‐
ance.
• To maintain good refrigeration performance, a refrigera‐
tion service person should be called periodically (at least
twice a year) to clean the discharge honeycomb and re‐
move any accumulated dirt from the condenser coil and
condensate evaporator pan on self‐contained models.
POOR CIRCULATION OF AIR THROUGH THE CONDENSER
COIL WILL RESULT IN POOR REFRIGERATION PERFORM‐
ANCE.
• Dirt accumulation inside the condensate evaporator pan
will reduce the pan's capacity and affect the efficiency of
the heater causing a burned out heater and an overflow
of defrost water onto the store floor.
Tips and Troubleshooting
Before calling for service:
• Check power. Ensure reliable electrical power supply to
the equipment
• Check shelf loading. Overstocking will adversely affect
case performance.
• If frost is collecting on fixture or product, verify that
store Humidity Control is working properly, and that no
outside doors/windows allow moisture into store.
