2.2 SHIPMENT AND TRANSIT
The machine has been assembled, operated and inspected
at the factory. Upon arrival at the final destination, the
entire machine must be checked for any damage which
may have occurred during transit.
With the method of packaging used, the machine 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 machine 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 MACHINE INSTALLATION
WARNING
Installation must be completed by a qualified
electrician/refrigeration specialist.
Incorrect installation may cause personal injury , severe damage to the machine and will void factory
warranty.
Figure 2-1 Space and Ventilation Requirements
Place a bubble level on top of the machine at each
corner to check for level condition. If adjustment
is necessary, level the machine by turning the
bottom part of each leg in or out.
C. The machine has a base gasket that must be
installed. Separate the gasket and install it with
the seam to the back. Make sure the angled side
of the gasket is facing up.
D. Correct ventilation is required. The right side of the
machine is the air intake and left side is the
discharge. Both sides must have 3" clearance.
CAUTION
Failure to provide adequate ventilation will void warranty.
E. Place the Main Freezer Power Off/On switch in the
OFF position.
F. Connect the power cord to the proper power
supply. The plug connected to the machine is a
NEMA 6-20P. Check the nameplate on your
machine for proper supply. The unit must be
connected to a properly grounded receptacle.
The electrical cord furnished as part of the machine
has a three prong grounding type plug. 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
circumvent the grounding requirement.
Installation of the machine involves moving the machine
close to its permanent location, removing all crating,
setting in place, assembling parts, and cleaning.
A. Uncrate the machine.
B. Accurate leveling is necessary for correct drainage
of machine barrel and to insure correct overrun.
WARNING
Do not alter or deform electrical plug in any way.
Altering the plug to fit into an outlet of different configuration may cause fire, risk of electrical shock,
product damage and will void warranty .
