2.2 SHIPMENT AND TRANSIT
The freezer has been assembled, operated and inspected
at the factory. Upon arrival at the final destination, the
complete freezer must be checked for any damage which
may have occurred during transit.
With the method of packaging used, the freezer should
arrive in excellent condition. THE CARRIER IS RESPON-
SIBLE FOR ALL DAMAGE IN TRANSIT, WHETHER VIS-
IBLE OR CONCEALED. Do not pay the freight bill until the
freezer has been checked for damage. Have the carrier note
any visible damage on the freight bill. If concealed damage
and/or shortage is found later, advise the carrier within 10
days and request inspection. The customer must place
claim for damages and/or shortages in shipment with the
carrier. Stoelting, Inc. cannot make any claims against the
carrier.
2.3 FREEZER INSTALLATION
Installation of the freezer involves moving the freezer close
to its permanent location, removing all crating, setting in
place, assembling parts, and cleaning.
A. Uncrate the freezer.
B. Accurate leveling is necessary for correct drainage
of freezer barrel and to insure correct overrun.
Place a bubble level on top of the freezer at each
corner to check for level condition. If adjustment is
necessary, level the freezer by turning the bottom
part of each leg in or out. Then separate freezer
base gasket and install with seam to the back and
angle to the top.
C. If the freezer is equipped with an air cooled
condenser, correct ventilation is required. The right
side of the freezer is the air intake and left side
discharge. Both sides must have 3" clearance the
top requires 10" of clearance.
CAUTION
Failure to provide adequate ventilation will void war-
ranty.
D. Place the OFF-ON switch in the OFF position.
E. Connect the power cord to the proper power
supply. The plug is designed for 208 or 230 volt/20
amp duty. Check the nameplate on your freezer for
proper supply. The unit must be connected to a
properly grounded receptacle. The electrical cord
furnished as part of the freezer has a three prong
grounding type plug (Fig. 2-3). The use of an
extension cord is not recommended, if necessary
use one with a size 12 gauge or heavier with ground
wire. Do not use an adapter to get around grounding
requirement.
WARNING
Do not alter or deform electrical plug in any way.
Altering the plug to fit into an outlet of different con-
figuration may cause fire, risk of electrical shock,
product damage and will void warranty .
F. Install the drip tray, drain tray, hopper cover and
other miscellaneous parts on the freezer.
