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 RESPONSIBLE FOR ALL DAMAGE IN TRANSIT, WHETHER
VISIBLE 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
spirit 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. (Fig.
4).
Figure 5. Space and Ventilation Requirements
E. Connect the power cord. 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. 6). 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.
Figure 4 - Leveling
C. The freezer is equipped with an air cooled condenser
and requires correct ventilation. 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. (Fig. 5).
