Important Steps
1. Do not set temperature too cold, as this causes
product dehydration.
Refer to case specs section
for proper settings.
2. Temperature control should be by means of a
T-STAT and Suction Stop Solenoid at each case.
Do not use EPR valves, Liquid Line Solenoids or
electronic control devices of any kind, as these
allow temperature swings causing dehydration and
excessive energy consumption.
Case Cleaning
Long life and satisfactory performance of any equipment are
dependent upon the care given to it. To insure long life, proper
sanitation and minimum maintenance costs, the refrigerator
should be thoroughly cleaned frequently. SHUT OFF FAN
DURING CLEANING PROCESS. It can be unplugged within
the case, or shut off case at the source. The interior bottom
may be cleaned with any domestic soap or detergent based
cleaners. Sanitizing solutions will not harm the interior bottom,
however, these solutions should always be used according
to the manufacturer’s directions. It is essential to establish
and regulate cleaning procedures. This will minimize bacteria
causing discoloration which leads to degraded product
appearance and signifi cantly shortening product shelf life.
Soap and hot water are not enough to kill this bacteria. A
sanitizing solution must be included with each cleaning
process to eliminate this bacteria.
1. Scrub thoroughly, cleaning all surfaces, with soap
and hot water.
2. Rinse with hot water
, but do not fl ood.
3. Apply the sanitizing solution according to the
manufacturer’s directions.
4. Rinse thoroughly.
5. Dry completely before resuming operation.
Cleaning Glass and Mirrors
Only use a soft cloth and mild glass cleaner for cleaning any glass
or mirrored components. Be sure to rinse and/or dry completely.
Never use hot water on cold glass surfaces! It may
shatter and cause serious injury!
Allow glass surfaces
to warm fi rst.
CLEANING PRECAUTIONS
When cleaning:
•
Do not use high pressure water hoses
•
Do not introduce water faster then waste outlet can drain
•
NEVER INTRODUCE WATER ON SELF CONTAINED UNIT
WITH AN EVPORATOR PAN
•
NEVER USE A CLEANING OR SANITIZING SOLUTION
THAT HAS AN OIL BASE (these will dissolve the butyl
sealants) or an AMMONA BASE (this will corrode the
copper components of the case)
•
TO PRESERVE THE ATTRACTIVE FINISH:
•
DO USE WATER AND A MILD DETERGENT FOR THE
EXTERIOR ONLY
•
DO NOT USE A CHLORANITED CLAENER ON ANY
SURFACE
•
DO NOT USE ABRASIVES OR STEEL WOOL SCOURING
PADS (these will mar the finish)
CAUTION
Maintenance
BEFORE SERVICING
ALWAYS DISCONNECT ELECTRICAL
POWER AT THE MAIN DISCONNECT
WHEN SERVICING OR REPLACING ANY
ELECTRICAL COMPONENT.
This includes (but not limited to) Fans, Heaters
Thermostats, and Lights.
Evaporator Fans
The evaporator fans are located at the center front of these
merchandisers directly beneath the display pans.
Should
fans or blades need servicing, always replace fan blades
with the raised embossed side of the blade TOWARD THE
MOTOR.
Copper Coils
The copper coils used in Hussmann merchandisers may
be repaired in the fi eld. Materials are available from local
refrigeration wholesalers.
Hussmann recommends using #15 Sil-Fos for repairs.
Tips and Troubleshooting
Before calling for service, check the following:
1. Check electrical power supply to the equipment for
connection.
2. Check fi xture loading. Overstocking case will affect
its proper operation.
3. If frost is collecting on fi xture and/or product, check
that Humidity Control is working properly, and that
no outside doors or windows are open - allowing
moisture to enter store.
