spected at the factory. Upon arrival at the final destina-
tion, the freezer must be checked for any damage which
may have occurred during final transit.
With the method of packaging used, the equipment
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 dam-
age. Have the carrier note any visible damage on the
freight bill. If concealed damage and/or shortage is found
later advise the carrier within ten days and request in-
spection. The customer must place claim for damage
and/or shortages in shipment with the carrier. Stoelting,

2.3 FREEZER INSTALLATION
WARNING
INSTALLATION MUST BE PERFORMED BY A
QUALIFIED ELECTRICIAN/REFRIGERATION
SPECIALIST. INCORRECT INSTALLATION WILL
VOID THE WARRANTY, AND MAY CAUSE SE-
VERE DAMAGE TO THE MACHINE. MAY
CAUSE PERSONAL INJURY.
Installation of the freezer involves moving the freezer
close to its permanent location, removing all crating, set-
ting in place, assembling parts, and cleaning.
A. Uncrate the freezer.
B. Install the four casters. Turn the threaded end into
the freezer until zero threads are showing. To level,
turn out casters no more than 1/4" maximum, then
tighten all jam nuts.
C. The freezer must be placed in a solid level position.
NOTE
Accurate leveling is necessary for correct drainage
of freezer barrel and to insure correct overrun.
D. The freezer must have a minimum of 3" (7,5cm)
-6" (15cm) high ambient conditions- of space on all
sides and 10" (25cm) at the top for proper circula-
tion.
CAUTION
FAILURE TO PROVIDE ADEQUATE VENTILA-
TION WILL VOID WARRANTY!
E. Water-cooled freezers need an adequate water
supply. Install 1/2" (12,7mm) pipe or 1/2" (12,7mm)
inside diameter copper water line to the freezer.
Connect water outlet to a drain using a 1/2"
(12,7mm) inside diameter line. Automatic washer
hoses work well for final connections. All water
connections must comply with local codes. Fig. 4.
CAUTION
FLUSH ALL WATER LINES BEFORE INSTALLA-
TION. IN STORES WITH SEDIMENT IN WATER,
ADD SUITABLE FILTER OR STRAINER TO WATER
INLET.

F. Place the CLEAN-OFF-SERVE switches in the OFF
position before continuing. Figure 11.
2.4 INSTALLING PERMANENT WIRING
Permanent wiring is required by local codes, the follow-
ing procedure must be performed:
A. Refer to the nameplate at the rear of the freezer for
specific electrical requirements. Make sure the power
source in the building matches the freezer name-
plate requirements. Bring the wires into the junction
boxes through the access holes in the bottom rear of
the freezer. Figure 4.
NOTE
Three phase freezers in areas of unbalanced elec-
trical loads require special attention when connect-
ing input electrical power. The unbalanced leg of
power (called wild or high) must be connected to
L2 in the junction box.
B. Remove the lower back panel and the two junction
box covers located at the bottom of the freezer.
C. lnstall permanent wiring according to local code.
D. Check the auger shaft rotation by placing the MAIN
DRIVE switch in the CLEAN position. Auger shaft
rotation is clockwise as viewed through the clear
plastic front door. If the rotation is not clockwise,
turn main electrical power OFF. Then reverse L1
and L3 electrical power lines to the junction box
(three phase only). Re-check auger shaft rotation.
