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.
Note:
Do not overtighten the screws since damage may occur.
Stainless Steel Cleaning and Care
There are three basic things, which can break down your
stainless steel's passivity layer and allow corrosion.
1. Mechanical Abrasion
Mechanical Abrasion means those things that
will scratch the steels surface. Steel Pads, wire
Brushes, and Scrapers are prime examples.
2. Water
Water comes out of our tap in varying degrees of
hardness. Depending on what part of the country
you live in, you may have hard or soft water. Hard
water may leave spots. Also, when heated, hard
water leaves deposits behind that if left to sit, will
break down the passive layer and rust your stainless
steel. Other deposits from food preparation and
service must be properly removed.
3. Chlorides
Chlorides are found nearly everywhere. They
are in water, food and table salt. One of the worst
perpetrators of chlorides can come from household
and industrial cleaners.
Maintenance
When cleaning:
• Do not use high pressure water hoses
• Do not introduce water faster than waste outlet can drain
• NEVER ON A SELF CONTAINED UNIT WITH AN EVAPORATOR FAN
• NEVER 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 componets of the case)
To preserve the attractive finish:
• DO USE WATER AND A MILD DETERGENT FOR THE EXTERIOR ONLY
• DO NOT USE ABRASIVES OR STEEL WOOL SCOURING PADS
(these will mar the finish)
Rear Sliding Doors
To ensure proper sliding and eliminate
potential damage, the doors must be removed
and the tracks cleaned with soap and water
weekly.
If, after cleaning, the rear sliding doors become
too heavy or difficult to open/close, NSF/USDA
H1 lubricant & FDA 21 CFR compliant Silicone
Spray may be used as a lubricant on the guide
tracks
1. Follow the manufacturers directions when
using the spray. Hold spray can about 6
inches from the guide tracks. Starting from
one end of the track and working your way
to the other end, hold down the spray nozzle
as you apply a light coating over the track.
2. Using a dry paper towel or rag, rub the
lubricant into the tracks. If necessary, use
additional paper towels or rags to wipe off any
excess lubricant.
Additional Notes:
• Recommended product: Mr. Clearco Food Grade
Silicone Spray manufactured by Clearco
Products Co.
• DANGER: DO NOT spray directly on food
products. Move food away to a safe location
before using he spray
• Apply lubricant weekly, or as needed, especially
after cleaning debris from the door tracks
• Should the lubricant ever need to be removed
from the tracks, use only soap & water
• DO NOT use acetone or any hydrocarbon
based solutions even if the manufacturer of
the spray product may suggest them
• Using such products may damage the guide
track
