WARNING

WARNING - Help Prevent Tragedies

Child entrapment and suffocation are not problems of
the past. Junked or abandoned refrigerators are still
dangerous - even if they sit out for "just a few hours".

If you are getting rid of your old refrigerator, please
follow the instructions below to help prevent acci­dents.

If the unit was shipped or has been laying on its back for
any period of time allow the appliance to sit upright for a
period of at least 24 hours before plugging in. This will as­sure oil returns to the compressor. Plugging the appliance
in immediately may cause damage to internal parts.

Before you throw away your old refrigerator or
freezer:

• Take off the doors or remove the drawers.

• Leave the shelves in place so children may not
easily climb inside.

INSTALLING YOUR REFRIGERATOR OR FREEZER

Select Location

The proper location will ensure peak performance of your
appliance. We recommend a location where the unit will
be out of direct sunlight and away from heat sources. To
ensure your product performs to specications the recom­mended installation location temperature range is from 55
to 100°F (13 to 38°C).

Cabinet Clearance

Ventilation is required from the bottom front section of the
unit. Keep this area open and clear of any obstructions.
Adjacent cabinets and counter top can be installed around
the unit as long as the grille and door access remain unob­structed.

!

WARNING

An optional stacking kit is required to stack products.
Failure to use a stacking kit could result in personal
injury. Contact your dealer or Marvel customer service
at 800-223-3900 to order.

Front Grille,
keep this area
open.

Figure 2

Leveling Legs

Leveling Legs

Adjustable legs at the front and rear corners of the appli­ance should be set so the unit is rmly positioned on the
oor and level from side to side and front to back. The
overall height of your appliance may be adjusted higher (by
turning the leveling leg out, CCW) and lower (by turning the
leveling leg in, CW) dimensions as shown in Table "A".

To adjust the leveling legs, place the appliance on a solid
surface and protect the oor beneath the legs to avoid
scratching the oor. With the assistance of another person,
lean the appliance back to access the front leveling legs.
Raise or lower the legs to the required dimension by turning
the legs. Repeat this process for the rear by tilting the appli­ance forward using caution. On a level surface check the
appliance for levelness and adjust accordingly.

!

CAUTION

Front Grille

Do not obstruct the front grill. The openings within the front
grill allow air to ow through the condenser heat exchanger.
Restrictions to this air ow will result in increased energy
usage and loss of cooling capacity. For this reason it is im­portant this area to not be obstructed and the grill openings
kept clean. Marvel does not recommend the use of custom
made grills as air ow may be restricted because of inad­equate openings. (See Figure 2).

The front grille screws may be loosened and the grille ad­justed to the desired height. When adjustment is complete
tighten the two front grille screws. (See Figure 5).

If necessary to gain clearance inside the rough-in
opening a hole can be cut through the adjacent cabi­net and the power cord routed through this hole to a
power outlet. Another way to increase the available
opening depth is to recess the power outlet into the
rear wall to gain the thickness of the power cord plug.
Not all recessed outlet boxes will work for this applica­tion as they are too narrow, but a recessed outlet box
equivalent to Arlington #DVFR1W is recommended for
this application, (see Figure 10).

FEATURES

MS15RA, MS24RA and SA24RA features

There are three adjustable shelves for exibility of content
storage. The shelves can move up or down to accommo­date various content sizes.

Lock and Key

The optional lock and key allow you to lock and store con­tents.

Content Temperature versus Air Temperature

Air temperature moves up and down with door openings
and compressor run and off cycles. Air has little thermal
mass and therefore changes temperature relatively quickly
between on/off cycles. Stored contents have much higher
thermal mass so their temperatures change much slower.
Always measure temperature with a mass weighted sensor
to determine if the contents being stored are at the proper
temperature.

Probe Port

The probe port is a hole from the inside to the outside of
the unit, which is located on the back of the unit. (See
Figure 13). Remove the foil label and foam plug(s) from
the hole in the back of the unit, insert your probe or wires
through the hole in the back of the unit. Seal hole with foam
plug(s).
