3-1 START UP / OPERATION
START UP
Follow the controller start up procedures
as detailed in Section 3 of this manual.
Each self contained merchandiser has its
own evaporator coil and a pre-set
thermostatic expansion valve (TEV).
The TEV has been factory set at design
conditions to provide the recommended
performance.
TEVADJUSTMENT
Expansion valves may be adjusted to fully
feed the evaporator. Before attempting to
adjust valves, make sure the evaporator is
clear or only lightly covered with frost, and
the merchandiser is within 10°F of its
expected operating temperature.
Adjust the valve as follows:
a. Attach aprobe to the suction line near the
expansion valve bulb.
b. Obtain apressure reading from the factory
installed Schraeder valve. Convert the pres-
sure reading to asaturated temperature for the
refrigerant.
Temperature (b) minus Temperature (a) is the
superheat.The valve should be adjusted so that
the greatest difference between the two tem-
peratures is 3°F to 5°F.
Make adjustments of no more than 1/2turn of
the valve stem at atime and wait for at least
15 minutes before rechecking the probe tem-
perature and making further adjustments.
STOCKING
Product should NOT be placed inside the
merchandisers until merchandisers are at
proper operating temperature.
Allow merchandiser 24 hours to operate before
loading product.
Proper rotation of product during stocking is
necessary to prevent product loss.Always
bring the oldest product to the top and set the
newest to the bottom.
Air discharge and return flues must remain open
and free of obstruction at all times to provide
proper refrigeration and air curtain
performance.
Do not allow product, packages, signs, etc. to
block these grilles. Do not use non-approved
shelving, baskets, display racks, or any
accessory that could hamper air curtain
performance.
Do not allow product to be placed outside of
the designated load limits in the illustration.

CAREAND CLEANING
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.
Exterior Surfaces
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.
Interior Surfaces
The interior surfaces may be cleaned with most
domestic detergents, ammonia based cleaners
and sanitizing solutions with no harm to the
surface.
Do NOT Use:
•Abrasive cleansers and scouring pads, as these
will mar the finish.
•Coarse paper towels on coated glass.
•Ammonia-based cleaners on acrylic parts.
•Remove the product and all loose debris to
avoid clogging the waste outlet.
•Store product in a refrigerated area such as a
cooler. Remove only as much product as can
be taken to the cooler in a timely manner.
•Disconnect electrical power before cleaning.
•Thoroughly clean all surfaces with soap and
hot water. Do Not use steam or high water
pressure hoses to wash the interior.
These will destroy the merchandisers’ sealing
causing leaks and poor performance.
•Take care to minimize direct contact between
fan motors and cleaning or rinse water.
•Do NOT flood merchandiser with water.
Never introduce water faster thanthe
waste outlet caN remove it.
•Allow merchandisers to dry before resuming
operation.
•After cleaning is completed, turn on power to
the merchandiser.
Do:
•Solvent, oil or acidic based cleaners on any
interior surfaces.
•Do not use high pressure water hoses.
Product will be degraded and may spoil if
allowed to sit in a non-refrigerated area.
Do NOT allow cleaning agent or
cloth to contact food product.

HUSSMANN CORPORATION • BRIDGETON, MO 63044-2483 U.S.A.
P/N 3068445 _E

REMOVING SCRATCHES FROM
BUMPER
Most scratches and dings can be removed
using the following procedure.
1. Use steel wool to smooth out the surface
area of the bumper.
2. Clean area.
3. Apply vinyl or car wax and polish surface
for a smooth glossy finish.
CLEANING UNDER FAN PLENUM
After cleaning be sure the plenum is properly
lowered into position or producT loss will
resulT due to improper refrigeration.
CLEANING DISCHARGE AIR LOUVERS
Discharge air louvers should be cleaned every
six months. Dirty louvers will cause mer-
chandisers to perform poorly. The louvers
may be cleaned with a vacuum cleaner. Soap
and water may be used if all water is removed
from the louvers cells before replacing. Be care-
ful not to damage the louvers.
SHUT FANS OFF DURING
CLEANING PROCESS.
Do NOT use HOT water on Cold glass
Surfaces. This can cause the glass to
shatter and could result in personal
injury. Allow glass fronts, to warm
before applying hot water.
—LOCKOUT/ TAGOUT—
To avoid serious injury or death from electri-
cal shock, always disconnect the electrical
power at the main disconnect when servicing
or replacing any electrical component.This
includes, but is not limited to, such items as
doors, lights, fans, heaters, and thermostats.

U.S.& Canada1-800-922-1919• Mexico1-800-890-2900•www.hussmann.com

CLEANING STAINLESS STEELSURFACES
Use non-abrasive cleaning materials, and
always polish with grain of the steel.Use warm
water or add amild detergent to the water and
apply with acloth.Always wipe rails dry after
wetting.
Use alkaline chlorinated or non-chlorine
containing cleaners such as window cleaners
and mild detergents.Do not use cleaners
containing salts as this may cause pitting and
rusting of the stainless steel finish.Do not use
bleach.
CLEANING COILS
Condenser coils should be cleaned at least
once per month.Additional cleaning may be
needed depending on the operational environ-
ment. A dirty condenser blocks normal airflow
through the coils.
Airflow blockage increases energy consump-
tion and reduces the merchandiser’s ability to
maintain operating temperature.
To clean the coils, use avacuum cleaner with
awand attachment and asoft (non-metallic)
brush to remove dirt and debris.Do not bend
coil fins.Always wear gloves and protective
eye wear when cleaning near sharp coil fins
and dust particles.
DO NOT FLOOD!
Use only enough water necessary to clean
surface. Water must not drip down the case!
Never use ammonia based cleansers, abrasive
cleansers, or scouring pads.
