INTRODUCTION –

The HS and HD models have been
designed to giv e maximum performance
with minimum energy consumption. They
have the versatility in product temperature
range to be used for storage at sub zero to
dipping at desired above zero tempera­tures. All cabinets are UL and UL sanita­tion li sted.

INSPECTION

–

Upon receipt of the cabinet, c are­fully ex amine the crating for damage. If
damage is found make a note on the deliv­ery ticket before signing. Carefully remove
shipping crate and examine cabinet for
“concealed” damage. If damage is found
contact the delivering carrier immediately
and have his agent prepare an inspection
report for the purpose of filing a claim
THIS IS YOUR RESPO NSI BILIT Y.

SPECIFICATIONS

–

BASE

–

The cabinet base is an all welded as­sembly of very he avy g auge steel to estab­lish a strong foundation on which the rest
of the cabinet is built.

EXTERIOR SHELL

–

The shell is formed from heavy
gauge steel and is welded together as an as­sembly and then welded to the cabinet base
assembly to give complete strength and du­rability. This assembly is processed
through a chemical treatment and painted

with an enamel powder paint for a lasting
finish.

INTERI OR LINER

–

The li ner is an all welded steel ass em­bly. Copper evaporator tubing is fastened
to the exterior of the liner; and maximum
heat transfer is further enhanced with the
addition of a conductive material on both
top and bottom of the tubing. The liner is
also chemical treated and painted with an
enamel powder paint for a lasting finish.

SUB-TOP

–

The sub-top is an all welded heavy
gauge galvanized assembly with integral
molded plastic breakers. The sub top ties
the shell and liner assemblies together and
s erves as a back up for the main top to pre­vent denting.

INSULATION

–

The shell, liner and sub top assem­blies are foamed in place with a polyure­thane insulation providing outstanding insu­lating qualities and solid unitized construc­tion.

MAINTOP

–

The main top is a one piece design of
heavy gauge 18-8 rust proof stainless steel.
It has a brush satin finish to minimize
scratching and maintain a lasting clean ap­pearance.

3

CONDENSING UNIT –

All models incorporate a slide-out
condensing unit for easy access to all com­ponents. All have a bare tube condenser
design to minimize field maintenance.

INSTALLATION and START UP

LEV EL I NG

–

Lev el case front to back and end to
end, shimming where necessary upon in­stallation to assure proper operation of
drains and refrigeration systems.

PLUMBING

–

To simplify cleaning and for sani­tary purposes, we s uggest that a connec­tion be made from the cabinet drain tube
to a floor drain. A h ose fitti ng is supplied
for that purpose.

The HS and HD models are
equipped with three wire grounded service
cords . For your own protection, connec­tion mus t be made to a 115 volt grounded
receptacle and a power supply with a fif­teen ampere rating minimum.

The cabinets are designed to oper­ate on 115 volts, s ingle phase, 60 cycle cur­rent. A separate circuit is recommended to
prevent product l oss due to overloading or
malfunction of other equipment on the
same circuit. Use a 15 amp time delay
fuse. The supply circuit must conform to
National and local electric al codes.

A wiring diagram is provided on
the condenser shroud for case refrigera­tion.

VO LTAG E, AS ME ASURED AT
THE COMPRESSOR TERMINAL DUR­ING OP ERATION, MUST NOT VARY
MORE THAN 5% FROM CABINET SE­RIAL PLATE RA TING.

NOTE: DO NOT DRILL ANY HOLES IN
SIDE OF CABINET WITHOUT FIRST
GETTING INSTRUCTIONS FROM FAC­TORY SERVICE DEPARTMENT.

A space of 4 inches must be left open
at the front and back of the cabinet to in­sure proper air flow over the condensing
unit.

Cabinets should not be installed in
direct sunlight or near/under heat ducts for
proper operation.

********* IMPORTANT ***********

Cabinet should be started and al­lowed to cool down to n ormal operating
temperature before loading any products .

OPERATION and NORMAL
MAINTENANCE

TEMPERATURE CONTROL

–

The temperature control which
s enses the cold wall temperature, and is lo­cated behind the removable louvered grille
at the s ide of the case, is factory s et at the
3:00 o’clock position. Adjustment of the
contr ol is done by turning the knob clock­wise for colder temperatures and counter­clockwise for warmer temperatures.

DEFROSTING

–

Defrosting is accomplished manu­ally by scraping frost from areas where it
has collected on cabinet interior. Remove
excess ice and water. After washing and
drying thoroughly reconnect power supply.

5

CONDENSING UNIT –

The condens ing unit is mounted on
a slide-out base, acce ssible by removing the
access panel. The condenser is of the bare­tube des ign. The condenser fan motor
draws air through the condenser and
passes over the condenser for its cooling
and it is expelled out the back of the unit
compartment.

CLEANING CONDENSER

–

The bare-tube conde nser is designed
to require minimum maintenance. How­ever, to keep the unit at top efficiency,
check periodically, and remove any accu­mulated dust and debris.

To clean condenser, a soft, nylon
brus h should be used to loosen dirt and
lint. Then vacuum up the dirt or blow con­denser out with a high pressure gas such as
nitrogen. Never use a wire brush to clean
condens er tubes.

CLEANING EXTERIOR

–

When cleaning the exterior of the
cabinet use a soft cloth or sponge with wa­ter and a mild detergent. Rinse and wipe
dry.

CLEANING INT ERIOR

–

F or cleaning the interior of the liner
storage area, a flush out drain has been
provided with a standard hose fitting lo­ca ted in the front o f the c abinet in the bas e
area.

Disc onnect the electrical power cord

and wash using a soft cloth or sponge and
a mild detergent. DO NOT USE AN
ABRASIVE CLEANER OR S TEEL
WOOL – THESE WILL MAR THE FIN­ISH.

Wipe dry before restarting the cabi­net. Allow the cabinet to cool down to
proper temperature before reloading prod­uct.

PRESSURE CONTROL

–

The 10-HD with R-4 04A utilizes a
high pressure control as a safety device to
ensure the system is not subjected to exces­sive press ures. It trips out the compressor
at approx. 440 psi. and has an automatic
res et to res tart at 350 ps i .

High pressures normally result
from high ambient conditions and / or
dirty condensers. Correct such application
problems as soon as poss ible.
