GENERAL, INSTALLATION, CARE and CLEANING
GENERAL –
The Hussmann Models SHM have
been carefully designed to offer versatility
in the display of food items such as premade sandwiches, fresh fruit, and vegetables, cheeses, and deli items.
So that you can realize maximum
benefit from this fine piece of equipment
we urge both you and your installer to
carefully read and follow this brief set of
instructions prior to installation of the
equipment.
INSPECTION –
The equipment has been skidded
and crated prior to shipment from the factory. It is the carrier’s responsibility to deliver it to you in good condition until such
time as you sign for it. Upon receipt of the
cabinet, examine the packaging for damage. If the packing is damaged, make specific notation on the delivery ticket as to the
location and extent of damage prior to signing for the piece.
Carefully remove packaging and
examine the cabinet for damage. If damage is found, contact the delivering carrier
immediately and request that his agent prepare an inspection report for the purpose
of filing a claim. THIS IS YOUR RESPONSIBILITY NOT THE FACTORY’S.
Save all packaging materials and move the
cabinet as little as possible prior to inspection.
LOCATION –
Avoid locating the cabinet where direct sunlight would shine into the fixture or
where drafts from air conditioning grills,
fans, and open doors could affect its operation. A minimum distance of two feet
should be allowed in the front of the case to
allow proper free air movement to and from
the condenser for maximum operating efficiency.
SKID -
The skid should be left on the cabinet
until it is near its final location. The skid
provides protection for both case and floor.
The skid is removed by raising one end of
the case approx. 6”, block securely and remove the 2 skid bolts on the raised end and
screw back into the holes 2 leg levelers.
The procedure is repeated on the opposite end. When the leg levelers are in
place, the case may be slid off the skid and
placed in its final location.
LEVELING –
The cabinet must be leveled properly
to insure full drainage of condensate water
from the evaporator coil. Level the case
from front to rear and end to end. Optional
legs can be provided for this purpose.
DRAINS
-
Remote draining is not required in
self-contained models. The condensate water from the evaporator drains out
Page 3
through the bottom of the cabinet into the
condensing unit compartment to a heated
condensate pan.
The pan uses a thermistor to sense
the presence of water in the pan and adjusts the amount of heat required to evaporate the water. Care should be taken to
insure the drain hose is properly trapped
and in the pan.
LEGS – (optional)
If required by Health Inspectors the
levelers can be removed and replaced with
NSF Approved legs to raise the case 6
inches for cleaning purposes. An optional
skirt kit can be provided to snap on the
legs.
CARE and CLEANING – EXTERIOR –
When cleaning the exterior of the
cabinet, use a soft cloth or sponges with water and a mild detergent. Rinse and wipe
dry. Do not use an abrasive cleanser on the
painted surfaces as this will mar the finish.
For plexiglass surfaces, use an approved plexiglass cleaner such as Craftics
20/20 Plasti-Cleaner
To check the interior drain – SHUT
OFF POWER TO THE CABINET! This
may be accomplished by turning off the
cabinet power switch or by turning off the
breaker located in the store electrical
panel. Remove the product from the cabinet. Lift up and remove the stainless steel
shelves. The drain is located in the center
of the interior bottom directly behind the
evaporator coil. Remove any pricing
Labels, product wrappers, etc., that may be
found over the drain opening. When finished checking, assemble cabinet in reverse
order, turn back on the power and allow
cabinet to pull down to proper operating
temperatures before restocking.
INTERIOR –
For cleaning the interior of the product compartment, remove the product, disconnect the electrical power, and allow cabinet to warm to room temperature.
Use a soft cloth or sponge with a mild
detergent to wash the interior. The drainage area and drain should be checked to insure that they have not become clogged.
If the condensate drain hose is removed from the electric condensate pan for
cleaning, it must be reinstalled prior to operating the case. Do not use an abrasive
cleanser on the painted surfaces as this will
mar the surface.
Wipe dry before restarting the cabinet. The time clock (see Electrical section)
should be reset to the correct time of day.
Allow the cabinet to cool down to proper
temperature before reloading product.
CLEANING STAINLESS STEEL
Generally soap and water will be sufficient for most cleanings when done often
and regularly.

When necessary several cleaning agents
can be used. Some of them are Comet, Bab-O,
Liquid NuSteel, Cooper’s Stainless Steel
Cleaner, Allen’s Stainless Steel Cleaner, etc.
SERIAL PLATE –
The serial plate is located on the interior left wall of the cabinet. It contains all pertinent information such as model, cabinet serial number, amperage rating, refrigerant type
and charge. This information will be needed to
install, service, or order parts for this piece of
equipment.
POWER REQUIREMENTS –
The SHM –3, 4, 5 & 6 use a 115/60/1
power source, with the SHM-3 and –4 models
using a 15 amp cord and the SHM-5 and –6
using a 20 amp cord. The SHM-8 requires
208/230-60/1 power and uses a 20 amp plug. It
is very important for the safety of you and
your customers to have each circuit grounded
properly.
A qualified electrician should perform
all wiring in accordance with the National
Electrical Code and/or all local codes
Separate circuits are recommended for
each case in order to prevent product loss due
to overloading or malfunction of other equipment on the same circuit. Fuses or circuit
breakers should be supplied for each circuit.
For proper operation of equipment, voltage as
measured at the compressor must not vary
more than 5% from the cabinet serial plate
rating.
If either a high or low voltage condition exists, contact your electrician, local power
company, or equipment manufacturer.
ELECTRICAL BOX –
The electrical box is located behind
the louvered access panel. The box contains
the items described below. On remote units
the box is used to bring the field supply to.
There is a grounding lug provided on these
models for grounding purposes.
POWER SWITCH
–
The main power switch is located behind the louvered access panel covering the
condensing unit compartment on the customer side of the case.
This switch controls all power to the
case.
