• View and download a copy of the warranty Owner
Warranty Registration Card

Warranty coverage begins the day the ice machine is
installed.

LuminIce® II

The LuminIce® growth inhibitor recirculates the air in the
ice machine foodzone over a UV bulb. This process will
inhibit the growth of common micro-organisms on all
exposed foodzone surfaces.

• LuminIce® bulbs require replacement on a yearly
basis.

• The control board can be set to automatically display
a reminder after 12 months.

• A remote light is available for reminder indication.

NOTE: LuminIce® and LuminIce® II bulbs are not
interchangeable; verify your model before ordering a
replacement bulb.

Cleanup Procedure for Accidental Bulb Breakage

The cleanup procedure is identical to the procedure used
to clean up compact fluorescent (CFL) or fluorescent tube
lights. These lights contain a small amount of mercury
sealed within a glass tube. Breaking these types of lights
will release mercury and mercury vapor. The broken bulb
can continue to release mercury vapor until it is cleaned
up and removed.

The latest EPA procedures can be viewed on their website
at www.epa.gov/cfl/cflcleanup.html.

Calculating Allowable Lineset Distance

Line Set Length

The maximum length is 100' (30.5 m).

Line Set Rise/Drop

The maximum rise is 35' (10.7 m).

The maximum drop is 15' (4.5 m).

35 FT. (10.7 M)

MAXIMUM DISTANCE

35 ft. (10.7 m) Rise: The maximum distance the

Condenser or Condensing Unit can be above the ice
machine.

15 FT. (4.5 M)

MAXIMUM

DISTANCE

15 ft. (4.5 m) Drop: The maximum distance the

Condenser or Condensing Unit can be below the ice
machine.

Part Number 000014794 5/17 29

Calculated Line Set Distance

The maximum calculated distance is 150' (45.7 m).

Line set rises, drops, horizontal runs (or combinations
of these) in excess of the stated maximums will exceed
compressor start-up and design limits. This will cause
poor oil return to the compressor.

Make the following calculations to make sure the line set
layout is within specifications.

1. Insert the measured rise into the formula below.

Multiply by 1.7 to get the calculated rise.
(Example: A condenser located 10 feet above the ice
machine has a calculated rise of 17 feet.)

2. Insert the measured drop into the formula below.

Multiply by 6.6 to get the calculated drop.
(Example. A condenser located 10 feet below the ice
machine has a calculated drop of 66 feet.)

3. Insert the measured horizontal distance into the

formula below. No calculation is necessary.

4. Add together the calculated rise, calculated drop,
and horizontal distance to get the total calculated
distance. If this total exceeds 150' (45.7 m), move
the condenser to a new location and perform the
calculations again.

Remote Ice Machine Usage with Non­Manitowoc Multi-Circuit Condensers

Warranty

The sixty (60) month compressor warranty, including
thirty six (36) month labor replacement warranty, shall
not apply when the remote ice machine is not installed
within the remote specifications. The foregoing warranty
shall not apply to any ice machine installed and/or
maintained inconsistent with the technical instructions
provided by Manitowoc Ice. Performance may vary from
Sales specifications. ARI certified standard ratings only
apply when used with a Manitowoc remote condenser.

If the design of the condenser meets the specifications,
Manitowoc’s only approval is for full warranty coverage
to be extended to the Manitowoc manufactured part of
the system. Since Manitowoc does not test the condenser
in conjunction with the ice machine, Manitowoc will not
endorse, recommend, or approve the condenser, and will
not be responsible for its performance or reliability.

Important

Manitowoc warrants only complete new and unused
remote packages. Guaranteeing the integrity of a
new ice machine under the terms of our warranty
prohibits the use of pre-existing (used) tubing or
condensers.

32 Part Number 000014794 5/17

Head Pressure Control Valve

Any remote condenser connected to a Manitowoc
Ice Machine must have a head pressure control valve
(available from Manitowoc Distributors) installed on the
condenser package. Manitowoc will not accept substitute
“off the shelf” head pressure control valves

CAUTION

,

Do not use a fan cycling control to try to maintain
discharge pressure. Compressor failure will result.

Fan Motor

The condenser fan must be on during the complete ice
machine freeze cycle (do not cycle on fan cycle control).
The ice maker has a condenser fan motor circuit for use
with a Manitowoc condenser. It is recommended that
this circuit be used to control the condenser fan(s) on the
multi-circuit condenser to assure it is on at the proper
time. Do not exceed the rated amps for the fan motor
circuit listed on the ice machine’s serial tag.

Internal Condenser Volume

The multi-circuit condenser internal volume must not be
less than or exceed that used by Manitowoc (see chart on
page 35). Do not exceed internal volume and try to add
charge to compensate, as compressor failure will result.

Part Number 000014794 5/17 33

Condenser ∆T

∆T is the difference in temperature between the
condensing refrigerant and entering air. The ∆T should be
15 to 20°F (-9.4 to -6.6°C) at the beginning of the freeze
cycle (peak load conditions) and drop down to 12 to 17°F
(-11.1 to -8.3°C) during the last 75% of the freeze cycle
(average load conditions).

Refrigerant Charge

Remote ice machines have the serial plate refrigerant
charge (total system charge) located in the ice maker
section. (Remote condensers and line sets are supplied
with only a vapor charge.)

CAUTION

,

Never add more than nameplate charge to ice
machine for any application.

Quick Connect Fittings

The ice machine and line sets come with quick connect
fittings. It is recommended that matching quick connects
(available through Manitowoc Distributors) be installed
in the multi-circuit condenser, and that a vapor “holding”
charge, 5 oz. (150 ml), of proper refrigerant be added to
the condenser prior to connection of the ice machine or
line set to the condenser.

Operational Checks

GENERAL

Manitowoc ice machines are factory-operated and
adjusted before shipment. Normally, new installations do
not require any adjustment.

To ensure proper operation, always follow the
Operational Checks:

• when starting the ice machine for the first time

• after a prolonged out of service period

• after cleaning and sanitizing

NOTE: Routine adjustments and maintenance procedures
are not covered by the warranty.

Important

Refrigeration compressors must be operated for a
minimum break in period of 24 hours before full ice
production will be reached.

ICE THICKNESS CHECK

The ice thickness probe is factory-set to maintain the ice
bridge thickness at 1/8 in. (3 mm).

NOTE: Make sure the water curtain/splash shields are in
place when performing this check. It prevents water from
splashing out of the water trough. Remove the curtain to
make an adjustment, then replace immediately after the
adjustment is made.

1. Inspect the bridge connecting the cubes. It should
be about 1/8 in. (3 mm) thick.

2. If adjustment is necessary, turn the ice thickness
probe adjustment screw clockwise to increase
bridge thickness or counterclockwise to decrease
bridge thickness. Set a 9/32” gap between the ice
thickness probe and evaporator as a starting point.
Then adjust to achieve 1/8” ice thickness.

3. Make sure the ice thickness probe wire and the
bracket do not restrict movement of the probe.

Control Board Timers

The control board has the following non-adjustable
timers:

• The ice machine is locked into the freeze cycle for 6
minutes before a harvest cycle can be initiated. This
can be overridden by initiating a manual harvest.
Refer to “Manual Harvest” on page 85

• The maximum freeze time is 35 minutes at which
time the control board automatically initiates a
harvest sequence.
Firmware 5.009 or earlier - Maximum freeze time
is 60 minutes at which time the control board
automatically initiates a harvest sequence.

• The maximum harvest time is 7 minutes, the control
board will preform a water thaw cycle and then
return the ice machine to the freeze cycle.
Firmware 5.009 or earlier - The maximum harvest
time is 3.5 minutes. The control board automatically
initiates a freeze sequence when this time is
exceeded.

• The maximum water fill is 12 minutes.
