withstand washing and cleaning. All labels must remain
legible for the life of the freezer. Labels should be

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. The freezer must be placed in a solid level position. To
level adjust casters. Figure 3.
C. The freezer is equipped with an air cooled condenser
and requires correct ventilation; the front is the intake
and the back is the discharge. Both front and back
require 3" clearance for proper operation.
D. Place all switches in the OFF position.
E. Connect the two power cords. The plug is designed for
208/230 volt/20 amp duty. 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. The use of an extension cord is
not recommended. If one must be used, use one with
a size 12 gauge or heavier with a ground wire. Do not
use an adaptor to get around grounding requirements.
CAUTION
DO NOT ALTER OR DEFORM PLUG IN ANY WAY!
F. Install the drip tray, cover and other miscellaneous
parts on the freezer.
