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.

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

• 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

Important
Follow instructions in the maintenance section of
Initial Start-Up
1. Water Inlet
Turn the toggle switch to wash/fill,the water fill valve and pump
are en ergized, wait for 90 seconds, th en turn the switch to off
position.The water inlet valve on thi s machine energ i zes i n the
harvest cycle, therefore pr i ming the system with water will allow
the system to start up next cycle with a full reservoir of water.
2. Freez e Cyc le
Turn the on/off/wash switch t o on. Th e compre s sor, and wate r
pump wil l start, thu s s tarting th e fr eezing cycle. The pump spr ays
water in to the inverted cups. The water freez es layer by layer,
until an ice cube forms in each cup.
At th e same time the comp ressor star ts, the condenser fan motor
(air-cooled models) is supplied with power throughout th e freeze
and harvest cycles. The freeze cycle continues and t he eva porator
therm ostat reach es the adjust ed s et point.

3. Harvest Cycle
The compressor con tinues to operate an d the water pump is deenergized. The hot gas val ve e nergiz es, allowin g hot gas to ent e r

The hot ga s valve, and water va lve de-energi ze. If ice cubes are
not contacting th e bin thermostat a new freez e cycle is initiated
as the water pump energizes and sprays water into the cups,.
4. Automatic Shut-Off
When th e storage bin is full, the ice will come in contact with the
bin thermostat which is located inside the bin. The machine will
stop after approximately one minute of continuous ice contact
with the bi n thermostat probe.
The ice machine remains off until enough ice has been removed
from the storage bin to allow the ice to fall clear of the bin
therm ostat probe. A s the ice cl ears the probe, the bin ther mostat
warm s up an d the machine starts another freeze cycle.
• EC30/40/50/65/80
The thermostat energizes the tim e d elay relay. When the timer

AIR-COOLED CONDENSER
A dirty condenser r es tr icts air fl ow, resulting in excessi v ely high
operating temperatures. This reduces ice production and shortens
component life.
Clean th e condenser at least every six months.
1. Remove Plastic Front Grill removing two Phillips head
screws. C lean Grill opening s before repl a cing.
2. Clean the outside of the condenser with a soft brush or a
vacuum with a brush attachment. Clean from top to bottom,
not sid e to side. Be car eful not to bend the condenser fins.
WARNING

3. Shine a flashlight through the condenser to check for dirt
between the fins. If dirt remains:
A. Blow compr essed air through the condenser fins. Be
careful not to bend the fan blades.
B. If dirt or grease remains between fins, consult your
service representati ve.
4. Straighten any bent condenser fins with a fin comb.
WATER-COOLED CONDENSER
AND WATER REGULATING VALVE
The water-cooled con d enser and wa ter-regulating valve may
require cleaning due to scale build-up.
Low ice production, high water consumption and high oper ating
temperatures and pressures all may be symptoms of restrictions
in the condenser water circu i t.
Because the clean ing procedures requ ire special pumps and
