Shelves
Shipped inside each cabinet are 3 epoxy coated shelves
per door opening. Epoxy coated filler shelves are provid-
ed for units with more than one door. Shelf supports,
located in the plastic bag, are pushed into the side
pilasters, one in each corner, at the desired shelf height.
Replacement shelves are available individually. See
Replacement Parts for shelf part numbers. See Figure 2

Electrical Connection
Determine the total amount of current presently being
used by other apparatus connected to the circuit that will
be used by this freezer. It is critical that this added cur-
rent demand and other equipment on this circuit not
exceed the rating of the fuse or circuit breaker in use.
The frequency and nominal voltage requirements for the
unit are specified on the data plate, which is located on
the interiorʼs upper left side. Plug the unit only into a
power source that meets these requirements. Low line
voltage is often the cause of service complaints. With the
unit running, check that the line voltage is within ±10% of
that specified on the data plate.
The customer should have the wall receptacle and circuit
checked by a qualified electrician to verify the receptacle
is properly grounded and is connected to the proper
power supply. The following list gives the NEMA
plug/receptacle configuration for the corresponding freez-
ers.
