Water Service/Drains
WATER SUPPLY
Local water conditions may require treatment of the water to
inhibit scale formation, filter sediment, remove chlorine, and
improve taste and clarity.
WATER INLET LINES
Follow these guidelines to install water inlet lines:
•Do not connect the ice machine to a hot water supply. Be
sure all hot water restrictors installed for other equipment are
working. (Check valves on sink faucets, dishwashers, etc.)
•Water pressure to the machine should be between 1.4 to 5.5
bar (20 to 80 psi).
•If water pressure exceeds the maximum 5 bar recommended
pressure, obtain a water pressure regulator from your
Manitowoc distributor. Adjust pressure to 2.5 bar (37 psi).
•Install a water shut-off valve.
•Connect to a potable water supply only.
Important
If you are installing a water filter system, make sure that
you use a separate line for water-
cooled condenser.
Filter life will be greatly reduced if filtered water is used
for water-cooled condenser.
DRAIN CONNECTIONS
Follow these guidelines when installing drain lines to prevent
drain water from flowing back into the ice machine and storage
bin:
•Drain lines must have a 3.8 cm (1.5 inch) drop of run for
each meter (3 feet), and must not create traps.
•The floor drain must be large enough to accommodate
drainage from all drains.
•Run separate bin and water-cooled condenser drain lines.
Insulate them to prevent condensation.

Ice Machine Operation
Ice Machine Operation
Ice Making Sequence of Operation
Important
Prior to start up of this machine, a thorough
cleaning and sanitization should be performed.
Follow instructions in the maintenance section of
this manual.
Initial Start-Up
1. Water Inlet
Turn the toggle switch to wash/fill,the water fill valve and pump
are energized, wait for 90 seconds, then turn the switch to off
position.The water inlet valve on this machine energizes in the
harvest cycle, therefore priming the system with water will allow
the system to start up next cycle with a full reservoir of water.
2. Freeze Cycle
Turn the on/off/wash switch to on. The compressor, and water
pump will start, thus starting the freezing cycle. The pump sprays
water into the inverted cups. The water freezes layer by layer,
until an ice cube forms in each cup.
At the same time the compressor starts, the condenser fan motor
(air-cooled models) is supplied with power throughout the freeze
and harvest cycles. The freeze cycle continues and the evaporator
thermostat reaches the adjusted set point.
•EC18/20
A harvest cycle starts.
•EC30/40/50/65/80
The thermostat energizes the time delay relay. When the timer
reaches setpoint (10 minutes factory setting) the harvest cycle is
initiated.
3. Harvest Cycle
The compressor continues to operate and the water pump is de-
energized. The hot gas valve energizes, allowing hot gas to enter
and warm the evaporator.. The water valve is also energized,
aiding with harvest, as well as filling up the sump with fresh
water for a new freeze cycle.
The ice falls from the cups and is directed into the bin by the ice
chute. The harvest cycle continues until:
•EC18/20
The evaporator thermostat changes position.
•EC30/40/50/65/80
The timer reaches the factory setting of 3 minutes.
The hot gas valve, and water valve de-energize. If ice cubes are
not contacting the bin thermostat a new freeze cycle is initiated
as the water pump energizes and sprays water into the cups,.
4. Automatic Shut-Off
When the 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 bin thermostat probe.
The ice machineremains off until enough ice has been removed
from the storage bin to allow the ice to fall clear of the bin
thermostat probe. As the ice clears the probe, the bin thermostat
warms up and the machine starts another freeze cycle.

The cubes should have a small dimple in the center
2. Cycle times vary, according to surrounding air and water
inlet temperatures.
3. If cubes are not full (large dimple), turn evaporator
thermostat one increment towards theright to increase cube
size. Allow ice machine to complete three cycles. Check
cube
4. If cubes are too full, ( no dimple), turn evaporator thermostat
one increment towards the left to decrease cube size. Allow
ice machine to operate three complete cycles.
CUBE SHAPE
The standard cube has an average weight of 19 grams, while the large cube has an average weight of 32 grams.

Section 4
Cleaning the Condenser
WARNING
Disconnect electric power to the ice machine at the
electric service swi
tch before performing
maintenance on equipment.
AIR-COOLED CONDENSER
A dirty condenser restricts airflow, resulting in excessively high
operating temperatures. This reduces ice production and shortens
component life.
Clean the condenser at least every six months.
1. Remove Plastic Front Grill removing two Phillips head
screws. Clean Grill openings before replacing.
2. Clean the outside of the condenser with a soft brush or a
vacuum with a brush attachment. Clean from top to bottom,
not side to side. Be careful not to bend the condenser fins.
3. Shine a flashlight through thecondenser to check for dirt
between the fins. If dirt remains:
A. Blow compressed air through the condenser fins. Be
careful not to bend the fan blades.
B. If dirt or grease remains between fins, consult your
service representative.
4. Straighten any bent condenser fins with a fin comb.
WARNING
The condenser fins are sharp. Use care when
cleaning them.
WATER-COOLED CONDENSER
AND WATER REGULATING VALVE
The water-cooled condenser and water-regulating valve may
require cleaning due to scale build-up.
Low ice production, high water consumption and high operating
temperatures and pressures all may be symptoms of restrictions
in the condenser water circuit.
Because the cleaning procedures require special pumps and
cleaning solutions, qualified maintenance or service personnel
must perform them.
