Location of Ice Machine
Leveling the Ice Machine
The loca tion selected for th e ice machine mu st meet the
follo wing crit er ia. If any of these crit er ia are not met, select
another location.
• The location m ust be indoor s.
• The location must be free of airborne and other
contaminants.
• The air temperature must be at least 10°C (50°F), but must
not ex ceed 4 3 °C (110°F).
• The location must not be near heat-generating equipment or
in direct sunl ight.
• The location m ust be ca pable of supp orting the weight of the
ice ma ch ine and a full bin of ice.
• The loca tion must al low enough cl earance for water, dra in
and el ectrical con nection s in th e rear of the ice machine.
• The location must no t obstruct airflow through or a roun d the
ice machine (condenser airflow is in and out the front). Refer
to the ch ar t below for cl earance r ecom mendations.
* NOTE: The ice machine may be built into a ca binet.
There is no minimum clearance requirement for the top or left
and ri ght sides of th e ice machin e. Th e listed valu es are

WARNING
All wiring and ground connections
VOLTAGE
The maximum allowable voltage variation is ± 6% of the rated
volta g e on the ice machine model/serial num ber plate at s tart-up
(when the electrical load is highest).
All ice m achines ar e factory pr e-wired with a 2 meter (6 ft)
power cord, no plug is supplied
FUSE/CIRCUIT BREAKER
A separ at e fu s e/ circuit break er m u st be pr ovi d ed f or each ice
machine. An electr ical di scon nect swit ch mu s t be provided if the
ice machine is hard wired (wired without a plug).
TOTAL CIRCUIT AMPACITY
The tot al circuit ampacity is u sed to help select the wir e si ze of
the electrical s u p p ly.
The wire size (or gauge) is also dependent upon location,
materials used, length of run, etc., This must be determined by a
quali fi ed electrician.

WARNING
Risk Of Electri cal Sho ck
This ice machine must be properly grounded and
connected to the field wiring ter minal in
accordance with all applicab le national and local
electrical codes by a qualif ied e lect r ician. Be fore
connecting wires, d isco nnect po wer at the electrical
disconnect and lock out to prevent accidentally
energizing.Con nect all electrical wiring before use do not energize ice mach ine until installation is
1. Connect –the three suppl y lead wir es (Blue, Brown,
and Yellow/Gr een) to t he field wiring terminal, “L”, “N”,
and “G”, the Yellow/Green wir e m ust c onnec t to the
“G”(ground).
2. After connecting the wiring to the terminal strip, the
supply lead must be secured to the cabinet with a
strain relief near the terminal strip.
3. Verify wiri ng is cont ained in the electrical wiring box.

WATER INLET LIN ES
Follow these guidelines to install water inlet lines:
• Do not connect th e ice machine to a hot water suppl y. Be
sure all ho t w ater restrictors install ed for other eq u ipment ar e
working. (Che c k valve s on sink fau c e ts, dishwa sher s, etc.)
• Water pressure t o the machine should be between 1.4 t o 5.5
bar (20 to 80 psi).
• If water pressure ex ceed s t he maximu m 5 bar recommended
press ure, obtain a water pressure re gula tor fr om your
Manitowoc distri butor. Adjust pressur e to 2.5 bar (37 psi).
• Install a wate r shut-off va l ve.
• Connect to a pot able water s upply only.
DRAIN CONNECTIONS
Follow t hese guidelines when installing dra in lines to pr event
drain water from flowing back into the ice machine and storage
bin:
• Dra i n line s must have a 3.8 cm (1 .5 in ch) drop of run for
each meter (3 feet), and must not create traps.
• The floor drain must be lar ge enou gh to ac c ommodate
drainage from all drains.
• Run sep ar ate bin and water-cooled condens er drain lines.
