General

ll equipment should be thoroughly

examined for shipping damage before

and during unloading.

This equipment has been carefully

inspected at our factory and the carrie

has assumed responsibility for safe

arrival. If damaged, either apparent o

concealed, claim must be made to the

carrier.

Apparent Loss Or Damage

If there is an obvious loss or damage, it

must be noted on the freight bill o

express receipt and signed by the

carrier's agent; otherwise, carrier may

refuse claim. The carrier will supply

necessary forms.

Concealed Loss Or Damage

When loss or damage is not apparent

until after equipment is uncrated, a

claim for concealed damage is made.

Upon discovering damage, make

request in writing to carrier fo

inspection within 15 days and retain all

packing. The carrier will supply

inspection report and required claim

forms.

SHIPPING DAMAGE

Location

The SN Models (with glass tops) are

designed for indoor operation with a

recommended operating room maximum

ambient temperature range of 65 to 90°F

(18-32°C)/50-65% rh. The SM models

(open tops) are designed for indoo

operation with a recommended operating

room maximum ambient temperature o

75° F (24°C)/55% rh. Their performance

is affected by store air currents when the

doors are open. Do NOT allow ai

conditioning, electric fans, or open doors

and windows to create air currents

around these Spot Merchandisers no

should they be exposed to direct sunlight

or other heat sources.

NOTE: The condensing unit draws

ambient air through on side of the unit

and discharges hot air out by the

opposite side. In order to maintain prope

refrigeration performance and

compressor life, a minimum space of 4"

(10 cm) must be maintained between the

refrigerator and surrounding surfaces.

PREPARATION OF CABINET FOR OPERATION

Removing Cabinet From Skid

Move the Spot Merchandiser as close

as possible to its permanent location

and remove hold-down brackets at the

front and rear of the cabinet. Chec

refrigeration lines to see that they are

“free” and no damage has occurred

during shipping . Check fan blades fo

free operation.

Door Installation ( SN Models)

fter the merchandiser has been placed

to its final position, the doors may be

installed. The doors must be positioned

inside of each guide to have a good

seal.

Operation

lways allow the cabinet to warm up to

65° F before starting the unit. If the

cabinet has just been delivered from a

cold ambient, such as winter, wait least

16 hours before starting.

Should the unit be disconnected when

running, wait 5 minutes before restarting.

This allows the refrigerant pressures to

equalize and prevents the compresso

from cycling on its overload protector.

It is advisable to run the unit for 30 to 60

minutes before loading with merchandise.

This is to allow the air inside the Spot

Merchandiser to cool down.

Load Limits

Each merchandiser has a load limit decal.

t no time should merchandiser be

stocked beyond the load limits indicated.

If load limit is violated, it may result in

loss of contents.

REFRIGERATION SYSTEM

Description

ll Merchandisers are equipped with a

hermetic compressor. The refrigeration

system works with 404a refrigerant. It is

really important not to change or mi

refrigerants during service. If anothe

refrigerant than the specified is used,

the performance of the case will be

affected.

The refrigerant used is CFC free, that

means it does not damage the

stratosphere ozone layer.

The condenser is fin and tube

construction. The air is taken in at one

side of the cabinet through the lowe

grill and discharged out by the opposite

side.

Cooling is accomplished by the ambient

created by the cold walls.

Defrosting Instructions

When defrosting is necessary, remove

product, remove drain plug, disconnect

electricity and allow frost to melt.

Do not remove frost with a pick, knife o

by scraping with a sharp object.

Collect the water from defrost in a pan.

DO NOT allow the water to drain on to

the floor.

When the unit is finished defrosting,

clean the inside as described in section

4.1, install the plug on the drain tube and

connect the unit to the correct powe

supply.

P/N 2402398

4-1

START UP / OPERATION

Electrical Supply

Wiring of the unit is complete when it is

shipped from the factory. The unit is

supplied with a three conducto

electrical cord which extends from a

side of the unit. Plug the unit into

correct grounded outlet. It is

recommended that a separate circuit be

run for each cabinet to prevent the

possibility of another appliance blowing

a fuse, causing subsequent loss o

product.

Temperature Control

IMPORTANT

This unit has dual temperature range

freezer / refrigerator.

For refrigerator mode, turn UP toggle

switch. For freezer mode, turn DOWN

toggle switch. This switch is located

below the warning light.

You can change the temperature range

(freezer / refrigerator, or refrigerator /

freezer) without turning off the

condenser unit.

The flow of room air over the top of the

Spot Merchandiser should be minimized

for best refrigerating results. Avoid

placing your Spot Merchandiser in the

direct rays of the sun or in the ai

stream from electric fans or open

doorways.

High Pressure Switch

high pressure limit switch is provided

on all Spot Merchandiser Models. This

switch is used to limit the discharge

pressure of the compressor.

This switch will automatically cycle off the

compressor and turn on a warning light

on the base, when the discharge

pressure in the system is too high.

If this condition occurs, first clean the

condenser. If the warning light continues

to illuminate, call service.

This pressure switch is a safety device

and will not function during normal case

operation. Do NOT remove it from the

system.

Draining

The case is equipped with a bottom drain

tube and a plug for removing wate

during defrost and cleaning process.

Keep the plug connected to avoid ai

leaks.

Maintenance

Long life and satisfactory performance

of any equipment is dependent upon the

care given to it. To insure efficient

operation, proper sanitation and

minimum maintenance, the cabinet

should be thoroughly cleaned, debris

removed and the interior cleaned

regularly.

CAUTION

TO AVOID PERSONAL INJURY OR

DAMAGE TO ELECTRICAL

COMPONENTS, ALWAYS

DISCONNECT UNIT FROM MAIN

POWER SOURCE BEFORE

SERVICING OR CLEANING.

Cabinet Surfaces (Interior and

Exterior)

To preserve finish, the cabinet should

be cleaned with a mild solution of soap

and warm water only, using a soft cloth

or sponge. The white plastic top is

made of a tough ABS plastic. It is

strong, clean and durable. It can be

cleaned by wiping with a damp cloth

and, if necessary, a cleaner such as

Bon Ami could de used. DO NOT use

any type of caustic soap, abrasive

cleaner, or steel wool scouring pads

which can mar the cabinet finish.

The inside of your Spot Merchandise

has been coated for long life. It will give

many years of trouble free service.

Never use a sharp instrument to chip of

frost as this may damage the liner.

Condenser

The air cooled condenser should be

cleaned regularly. A dirty condense

restricts air flow,

causing decreased refrigeration

efficiency. (Clean every month or as

required).

1) With main power supply disconnected,

remove louver grill from front of lowe

cabinet. Most dirt will collect on the ai

intake side of the condenser. This is

opposite the fan motor.

2) Use a bristle brush to loosen the dust

and dirt and remove with a vacuum

cleaner. When cleaning condenser line

beware of fin edges as they are sharp.

3) If the Spot Merchandiser is located in

an area susceptible to grease collecting

on the condenser, scrub with a solution

of warm water and detergent. Care

should be taken to keep solution away

from wiring and electrical components.

Merchandiser Electrical Data

Spot Merchandiser data sheets are

attached to the back of this manual. The

data sheets provide case electrical data,

electrical schematics, parts lists and

performance data. Refer to the Spot

Merchandiser data sheets and case

serial plate for electrical information.
