AIR DISTRIBUTION and PRODUCT
LOADING –
This cabinet has a forced-air
circulation system. Air flows through the
back wall over the product on the shelves,
as well as out the honeycomb diffuser
located above the product, across the face
of the product (air curtain) and into the
return air grill.
Do not load product so that it
extends over the shelf edges or over the
return air grille.
POWER REQUIREMENTS –
The GSVM Models are equipped
for operation on a 115/60/1 power supply.
See chart in specifications for
requirements.
It is very important for the safety of
both you and your customer to have each
circuit properly grounded. A qualified
electrician should perform all wiring in
accordance with the National Electrical
Code and/or all local codes. Separate
circuits are recommended for each case in
order to prevent product loss due to
overloading or malfunction of other
equipment on the same circuit. For proper
operation of equipment, voltage as
measured at the compressor must not vary
more than 5% from the cabinet serial plate
rating. If either a high or low voltage
condition exists, contact your electrician,
local power company, or equipment
manufacturer.
ELECTRICAL BOX –
The electrical box is located behind
the louvered access panel. The box is
capable of sliding out for service after the
hold down screw is removed.
The box contains the power switch
and defrost time clock.
POWER SWITCH –
The main power switch is located
behind the front louvered access panel on
the side of the electrical box. This power
switch controls all power to the case. THE
CABINET POWER SWITCH MUST BE
IN THE OFF POSITION BEFORE
STARTING ANY CLEANING OR
SERVICE WORK ON THE
EQUIPMENT.
DEFROST TIME CLOCK –
The time clock, located in the
electrical box, provides a definite off-time
so that the evaporator will clear itself of
frost.
The clock is provided with pins to
initiate defrost. The failsafe setting sets
the length of defrost (from 2 minutes
minimum to 110 maximum).
The clock is factory pre-set for 3
defrosts (at 6 a.m. , 2 p.m. and 10 p.m.)
on the 4060 and 4072 at 20 minutes
