MARVEL Scientific 4EAF - Manual (Page 4)

These refrigerators and freezers have been engineered for in-
stitutional and industrial hazardous locations and meet Under-
writers Laboratories specifications for Class 1 Groups C and D.
Approved by the New York City Board of Standards and Appeals
under Calendar Number 496-80-SA.
Select Location
The proper location will ensure peak performance of your ap-
pliance. Choose a location where the unit will be out of direct
sunlight and away from heat sources.
The condenser is mounted on the back of the cabinet so the unit
cannot be built in. At least 1-1/2 inches (3.8cm) of clearance
from the back wall is required for proper ventilation.
Installation
The 4.5 and 6.1 cu. ft. refrigerators are designed for recessed as
well as freestanding installation.
To recess the 4.5 and 6.1 cu. ft. models make the opening
25-7/8” (657.4mm) wide x 35-3/4” (908.1mm) high x 27-1/2”
(698.5mm) deep with ample provision for wiring as described
in the following paragraph “Sealing” instructions. Other service
information can be found on pages 8 and 9. Provisions should be
made to easily remove the unit for servicing.
Do not back the unit up to heat ducts or hot water lines.
Cabinet Clearance
Ventilation is required from the bottom front section of the unit.
Keep this area open and clear of any obstructions.
Leveling Legs
Adjustable legs at the front and rear corners of the unit should
be set so the unit is firmly positioned on the floor and level from
side to side and front to back. Turn leveling legs clockwise to
raise unit, counterclockwise to lower it. (See Figure 1).
Electrical Connection
Check serial plate for correct power supply. Use only electrical
power supply as specified on your appliance serial plate.
Wiring
Hazardous location models are not supplied with power cords or
plugs. All wiring methods must comply with the latest National
Electrical Code, Article 501-4 for Class 1, Divisions 1 and 2.
Leveling Legs
Front Grille, keep
this
area open.

Sealing
Article 501-5 of the National Electrical Code Class 1, Division 1
requires that in Class 1 Division 1 locations, seals shall be located
as follows:
In each conduit run entering an enclosure for switches , circuit
breakers, fuses, relays, resistors, or other apparatus which may
produce arcs, sparks, or high temperatures, seals shall be placed
as close as practicable and in no case more than 18” (45.7cm) for
such enclosures.

Front Grille
Do not obstruct the front grill. The openings within the front
grill allow air to flow through the condenser heat exchanger.
Restrictions to this air flow 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. AGA
MARVEL does not recommend the use of custom made grills as
air flow may be restricted because of inadequate openings. (See
Figure 1).
