SHELVING -
The EVM models come equipped with
four shelves. They are adjustable on one inch
increments. When loading the shelves with
product, they should be loaded so that the prod-
uct does not extend over the front edge of the
shelf. Product loaded over the edge will inter-
fere with air circulation in the cabinet. It is also
desirable to leave a small space between the rear
interior wall and the product
to allow air to enter the cabinet interior through
the perforations in the rear wall.
The shelves are rated for 130 pounds
each load capacity. When installing the shelves,
first install the shelf support bracket at the de-
sired height. Place the rear of the bracket in the
desire slot. Raise the front of the bracket to-
wards the rear of the cabinet. Once the ends are
in the slot, rotate the bracket forward locking it
in place. Place the shelf on the bracket. Load
the product. The shelves are not to be slanted.
They must remain in a horizontal position.
TEMPERATURE CONTROL –
Interior cabinet temperatures are con-
trolled through the use of a bulb and capillary
type temperature control. The control is located
in the electrical box. The sensing element is
mounted on the left hand end of the evaporator
coil. The dial face of the control is marked with
readings that range from –10 to +50ºF.
The control is factory preset at 25º to 27º
to maintain 35-40º interior cabinet tempera-
tures. The differential is set at 8-10º, which is
the difference between cycle on and off tempera-
tures.
Turning the dial counter-clockwise will
achieve lower temperatures and turning it
clock wise will achieve higher temperatures.
