Maintenace
Case cleaning
• WARNING! DO NOT USE WATER HOSES! A self contained case emp•es
into an evaporator pan that WILL OVERFLOW IF TOO MUCH WATER IS
INTRODUCED during cleaning.
• To insure long life, proper sanita•on and minimum maintenace costs, the
case should be thoroughly cleaned frequently. SHUT OFF FAN BEFORE
CLEANING: turn controller dial to full counter-clockwise, or shut o• case
power at the source.
• USE WATER AND MILD DETERGENT FOR EXTERIOR USE ONLY
• Wipe interior with damp non abrasive cloth. Soap and hot water are not
enough to kill bacteria; a sani•zing solu•on must be included with each
cleaning process to eliminate bacteria.
• Clean any visible debris on-or near the case drain (drain is located under
the deck pans).
• DO NOT USE A CHLORINATED CLEANER ON ANY SURFACE.
• DO NOT USE ABRAISIVES OR STEEL WOOL SCOURING PADS (these will
mar the •nish)
• 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)
Filter Replacements
• REPLACE FILTER EVERY 6 MONTHS, or as needed. A dirty/clogged air
•lter restricts the air"ow. this will result in warmer temperatures in the
case, and premature compressor failure.
Service
• SCHEDULE SERVICE EVERY 6 MONTHS. To maintain good refrigerator
performance, a refrigera•on service technician should regularly clean
the discharge Honeycomb and remove any accumilated dirt from the
condenser coil and condensate evaporator pan.
• POOR AIR CIRCULATION THROUGH THE CONDENSER WILL RESULT IN
POOR REFRIGERATION PERFORMANCE, IN INCREASED PRODUCT TEM-
PERATURES, AND PERMANENT COMPRESSOR FAILURE
• Dirt accumila•on inside the condensate evaporator pan will reduce the
pan’s capacity and reduce the e#ciency of the heater causing a burned
out heater an an over"ow of defrost water onto the store "oor.
Tips and Troubleshoo!ng
Before calling for service:
• Check power. Ensure reliable electrical power supply to the
equipment.
• Check shelf loading. Overstocking will adversely a•ect case
performance.
• If Frost is collec•ng on •xture or product, verify that store Hu-
midity Control is working properly, and that no outside doors or
windows allow moisture into store.
Installa!on
Store Condi!ons
• Case is designed to operate at temperatures 80°F at 55% rela-
•ve humidity. Case must be kept in that environment to ensure
case performance and product safety.
• DO NOT posi•on the case near HVAC vent. a minimum of 15’
clearance is required.
• DO NOT posi•on the case near an entrance door. Outside
Ambient condi•ons have adverse a•ect on refrigera•on per-
formance.
• DO NOT posi•on case against ceiling or so#t. a minimum
clearnace of 8” above the unit is required for proper compres-
sor discharge air"ow.
• DO NOT block case front panel vent (supplies cri•cal intake
air"ow to the compressor). INTAKE AIR temperature should
not exceed 80°F.
For prompt service when contac•ng the factory regarding
problems, be sure to have the Case Model and Serial Number
handy. This imforma•on is on a platelocated on itself.
