INSTALLATION INSTRUCTIONS
B. Install the four casters. Turn the threaded end into
the machine until no threads are showing. To
level, turn out casters no more than 1/4" maximum,
then tighten all jam nuts.
C. The machine must be placed in a solid level
position.
NOTE
Accurate leveling is necessary for correct drainage
of freezing cylinder and to insure correct overrun.
D. Machines with air-cooled condensers require 3"
(7,6 cm) air space on both sides and back for
proper circulation. (Fig. 2-1)
E. Machines that have a water-cooled condenser
require 1/2" NPT supply and drain fittings.
F. In air-cooled machines, use a voltmeter to measure
incoming voltage. If the supply voltage is 215 or
less, then the buck-boost transformer must be
connected to the fan motor. Refer to the wiring
diagram located behind the header panel to
connect.
NOTE
Supply voltage must be checked to make sure the
fan motor operates properly.
2.4 INSTALLING PERMANENT WIRING
If permanent wiring is required by local codes, the follow-
ing procedure must be performed:
A. Refer to the nameplate on the side panel of the
machine for specific electrical requirements. Make
sure the power source in the building matches the
nameplate requirements.
B. Remove the back panel and the junction box
cover located at the bottom of the machine.
