Equipment Overview
Your ice machine consists of several main components. The
compressor, condenser coil, evaporator, auger, auger motor,
expansion valve, solenoid, water reservoir and electrical
control. Additionally you require a bin sensor, insulated
transport tube, fresh water ltration system, seawater pump,
sea strainer, piping and ttings.
The fresh water is regulated into the evaporator where it
freezes on the walls. The Auger motor rotates the auger to
scrape the ice build-up o the walls. The harvested ice is
compacted and pushed towards the auger outlet.
A 0.75” reinforced hose connects the auger outlet to the ice
bin. Insulate the hose and route it in a direct route toward
the bin, avoiding dips, bends and high spots along its path.
Support the hose at designated intervals and must be one
continuous hose. Do not connect two pieces of hose together.
The bin level sensor shuts o the ice machine when the bin
is full. The system automatically restarts when the ice level
drops and the sensor opens.
The condenser coil cools the refrigerant circuit and requires
adequate seawater ow. A centrifugal pump draws the raw
water through a sea strainer to the inlet of the condenser
coil. The water passes through the coil and draws heat out
of the refrigerant circuit; the heated water is then discharged
overboard. A TE250 pump will suce for most applications.
It is recommended that the ice machine has a dedicated raw
water circuit with its own pump. If a shared pump is used
the ow rate to the ice machine must be veried.
The ice machine control operates and monitors the system.
If a fault condition occurs the control will shut the system
down to protect the components. See the Commissioning
and Troubleshooting sections for more details.
Introduction
Environmental Conditions
Ambient and water temperatures can aect system perfor-
mance. Only operate the machine within the design param-
eters. Failure to do so can cause damage to the system and void
the warranty. See the Specications section for more details
How It Operates
The ship’s fresh water supply connects to the ltration
system (Mandatory Item). Flex tubing or soft drawn copper
pipe is routed and connected between the ltration system
and fresh water inlet on the unit. A 45˚ SAE are connec-
tion is standard on the unit. There is a special adapter for a
compression tting if needed. The tubing must be new and
clean; do not use old tubing or water lters.
Fresh water from the lter feeds the water reservoir and has
a control solenoid on the inlet of the reservoir. This solenoid
closes when the ice machine is not in operation.

When handling the unit use gloves and any other safety
equipment deemed necessary to prevent bodily injury.
Protect surfaces to prevent damage when transporting
equipment onboard and during installation.
The frame on for unit is capable of supporting the weight
of the unit. To aid installation and carrying the unit, the
top cover can be removed and the unit carried by the top
of the frame. To remove the top cover, use a at-head
screwdriver to turn the latches 180 degrees counter-clock-
wise.
Check that you have all the parts needed for the installa-
tion.
Mount the unit on a at surface to prevent vibration.
Locate the unit as far aft as possible and low in the boat.
Do not mount it further forward than amidships
The unit has two drains. For best drainage mount the unit
so that the drains are fore & aft.
Connect both drain lines on an incline downward to a
sump pump. If you decide to connect only one drain con-
nection, cap the other.
There are four mounting clips provided to secure to
machine to its mounting surface. (Figure 3) Install the
clips once the installation is complete and the panels are
in place. Use all four clips to secure the unit properly. For
the most secure application, mount the clips opposite each
other. This can be two on either side or one on each of the
four sides.
Installation
You only need to remove two panels for installation, the
top cover and the left-hand side panel.
Removing the top cover provides access to the electri-
cal box and for connection of the ice delivery hose. To
remove the top cover turn the captive locks 180 degrees
counter-clockwise.

Raw Water Pumps are not self-priming, lack a suction lift,
and thus require a ooded suction. Pumps cannot be run
dry because the impeller requires the liquid being pumped
for lubrication.
Install the raw water pump and strainer so that they are
below the waterline no matter the plane or pitch of the
vessel (Figure 7, below left).

The pump and strainer should accessible for maintenance
and service, not in a location where they can be stepped
on or damaged.
Install isolation valves so that the pump and strainer can
be maintained or serviced.
There are only two mounting positions for the pump
installation. Position “A” is the preferred mounting
(Figure 8, below).
Installation
Fig. 9: Hose stretching
Fig. 8: Pump installation
When connecting ttings to the pump inlet and outlet use
Teon tape or other type of pipe sealant.
Hand tight is sucient, DO NOT OVER-TIGHTEN.
Using excessive force can split or break o the pump
head. The weight of the water in the pump outlet hose,
combined with the weight of the hose, can stress the pump
outlet connection. Any type of impact on the hose can also
stress the connection. Support the hose within 18” (46cm)
of the pump outlet.
Insulate the ice delivery hose with a minimum of ½” thick
insulation. Secure the hose on the auger outlet with a
constant torque hose clamp. Connect the outlet of the hose
to the ice bin using a bulkhead tting to prevent restric-
tion at the outlet. Secure the hose at the bulkhead tting to
prevent it from pulling out.
If you have diculty getting the ice delivery hose onto
the auger outlet, heat the hose and stretch it out using slip-
lock pliers. To heat the hose immerse in hot water or use a
heat-shrink gun. Burn hazard use caution and wear safety
gear. Additionally, spraying the auger outlet and inside of
the hose with 409® cleaner to lubricate it.

Installation
Support the ice delivery hose every 12” (31cm).
For best performance, install the ice delivery hose
on a steady incline from the unit to the ice bin. Limit
the amount of bends and dips in the hose. If a bend is
unavoidable then the bend radius should be greater than
12” (30cm). The more dips in the hose produces a lower
quality of ice upon initial start-up.
Install the end of the outlet delivery hose as high as pos-
sible in the ice bin.

The power and sensor wires connect to the terminal
blocks inside of the electrical enclosure, and to the circuit
board. Remove all power to the machine and make sure
it is locked-out when working on the electrical wiring.
Insert the eld wiring into the Cage Clamp® connections
on the terminal blocks and circuit board. To do so insert
a 3/32” (2.5mm) at head screwdriver into the square
hole behind the round wire receptacle. Push rmly and
you will feel the cage clamp release. Strip the wire end
between 0.31” – 0.40” (8mm-10mm) and insert into the
round receptacle until it bottoms out. Remove the screw-
driver to engage the clamp on the wire.
Installation
Mount the bin full sensor within 3” (7.6 cm) of the outlet
of the hose at the 4 o’clock or 8 o’clock position (Figure
11, below) Do not mount directly under the hose outlet.
The sensor has two threaded nuts to secure it to the ice
bin. To make it a watertight penetration use a sealant. Use
a type that will allow the sensor to be removed if needed.
A special cable is provided for the sensor.
Connect the fresh water supply to an approved lter. Fail-
ure to install a lter voids the warranty. Then connect the
lter to the unit (Figure 12, below).
There are two penetrations in the panel at the rear of
the unit. The power supply, raw water pump and ice bin
sensor can be routed through these penetrations. For ease
of installation, we provide a wiring harness with heat-
shrink butt connectors for the pump. Always use heat-
shrink or heat-shrink butt connectors when making any
eld wiring connections.

Start-Up Procedure
Turn on the circuit breaker in the ship’s panel.
Turn on the on/o breaker on the outside of the ice
machine’s electrical box.
Allow time for the digital display to power up. Once
powered up and the main screen is shown, press the start
button.
The waiting indication will ash as the time delay counts
down for the compressor to start. During this waiting
period the fresh water solenoid is open and the oat
assembly and auger are lling with water. The auger and
raw water pump are on then the compressor starts. The
running indicator will now be on. Ice is produced and
pushed through the transport hose to the ice bin.
Monitor the system operation and ice production. Check
for any leaks of the fresh water and raw water connection.
Verify that the raw water is discharging overboard.
When the ice bin is full, the sensor will shut down the
unit. After the compressor stops the auger motor and raw
water pump continue to operate for 1 minute.

DAILY
• Raw Water Strainer
Raw water strainers are mandatory for all systems.
Check the raw water strainer daily. A visual inspection
through the sight-glass housing is usually sucient for
daily inspections. Open the strainer and inspect at least
once a week or if debris build up is noted. Make sure you
close the thru-hull valve prior to opening the strainer for
service.
WEEKLY
• Raw Water Strainer
Open the strainer and inspect at least once a week or if
debris build up is noted. Make sure you close the thru-hull
valve prior to opening the strainer for service.
Remove any debris from the strainer sight-glass housing
and strainer basket. Flush the strainer basket and clean/
vacuum out the housing prior to inserting the basket back
into it. Some strainer sight-glass housings incorporate a
drain plug to help with cleaning.
Some applications use a ‘Sea Chest’ for the raw water
supply. The strainer for the Sea Chest may have a large
mesh that does not lter small particulate. Install a
strainer between the Sea Chest and the raw water pump
inlet to lter out this small particulate.
Replace the strainer basket immediately if it is showing
signs of decay or damage. Do not operate the system with
the strainer basket removed. Inspect the housing and tie
rods for cracks or signs of deterioration. Replace defective
parts immediately to prevent the risk of ooding.
Gaskets or O-Rings are used to seal the strainer and can
easily fall into the bilge when the lid is removed. Always
check that the seals are in place prior to closing-up the
strainer. Prior to tightening the retaining bolts or clips,
check the seating of the seals. Replace loose or damaged
seals. Use caution, over-tightening of retaining bolts and
clips can crack the housing or strip threads.
Cracks in the sight-glass housing or a poor seal can cause
a suction leak. This can allow air to enter the inlet of the
pump when it is in operation. Air bubbles in the pump
head can cause cavitations that erode the impeller and
pump head on metal pumps. It can also damage the shaft
seal. It causes binding of the impeller on plastic head
pumps.
Check bonding lugs for corrosion and tightness on metal
strainers. Clean and replace connections as necessary.
Maintenance
QUARTERLY
• Condensate Drains
Pour a quart of water into the condensate pans. If it does
not drain quickly then check the drain pan and lines for
blockages.
•Electrical Connections
Inspect electrical connections and tightened as needed.
Heat and vibration can cause connections to loosen
causing poor contact and voltage drops. This can lead to
arcing, burnt wires and nuisance tripping of the breaker.
Remove electrical power and lockout prior to performing
electrical checks.
• Hose Clamps
Check the hose connections on the condenser coil, auger
outlet, pump, sea strainer and thru-hull ttings. In most
situations, a nut-driver or screwdriver will provide suf-
cient torque to tighten a clamp. Use caution when using
a socket set, it is easy to over tighten the clamp and cause
damage to its threads.
Do not use power tools to tighten hose clamps!
• Insulation
Inspect insulation for tears or open seams. Replace or
repair damaged sections as necessary.
• Thru-Hull Fittings
Debris such as plastic bags can be sucked onto thru-hull
ttings causing a restriction of water ow. Marine growth
build up can also be a problem. Inspect thru-hulls and
clean before the restriction becomes severe. Severe water
restrictions diminish the capacity of the system and can
cause pump failures.
• Fresh Water Filter
When the ice machine is in constant use, replace the
water lter cartridge every three months. For occasional
or weekend use replace every six months. To remove the
lter turn o the fresh water supply. Place a container
under the lter housing to catch any water that spills out
when removing it. To release, turn the housing in the
direction of the arrow until it stops, then pull down. Some
lter housings can be turned by hand and some require
a wrench. To prevent damage to the housing use the
wrench provided by the manufacturer.

YEARLY
• Condenser Coils
Back ush condenser coils annually, or more frequently
depending on water quality. Periodically chemical clean-
ers are needed to remove marine growth or scale. Consult
the condenser coil cleaning section for instructions on
chemically cleaning the coils. We recommend that certi-
ed technicians perform this service.
Condenser Coil & Raw Water System Cleaning
Prior to cleaning the condenser coil or raw water piping
take baseline readings such as refrigerant pressures,
amperages and the temperature of each condenser coil
wrap.
Turn o the unit and raw water pump. Close the thru-hull
valve.
The entire raw water system can be ushed at the same
time. However, the most eective way to clean the system
is to isolate each section (condenser, manifold, piping)
and clean individually.
Before using chemicals to clean the system it should be
back-ushed with fresh water into a container. The pres-
sure generated from the dockside water connection or the
onboard fresh water pump is usually greater than what is
generated by the system's raw water pump. This pressure
can usually ush out a signicant amount of debris and
contaminants from inside the system.
After the back-ushing; the system should be checked
again to see if there was a change in the baseline read-
ings. If within the normal range then no further cleaning
is needed.
Back-ushing with fresh water should be part of your
maintenance schedule. The frequency is dependent on
the usage of the system and water conditions in the areas
where the boat operates. It may only require it once a year
or every 3 months. In harsh conditions it may be required
more frequently.
If the back-ushing has minimal impact on the system
cleanliness then chemical cleaning is needed.
There are numerous chemicals available for cleaning raw
water systems onboard vessels. Some are environmentally
friendly and some are more aggressive. Any chemical or
mix used for the cleaning of the system must be captured
and disposed of in accordance with Federal, State and/or
Local Regulations.
Maintenance
Follow all directions and warnings provided by the manu-
facturer of the chemical. Safety equipment and clothing
must be used to protect personnel and prevent damage to
the surrounding area or equipment.
Chemical cleaners are available at local Marine Whole-
salers, Online or at Commercial Supply Houses. When
selecting a cleaner make sure it is compatible with the
materials in the raw water circuit. Some cleaners are made
to clean a specic contamination such as Algae or Crusta-
ceans and Calcication, some clean a broad spectrum of
contaminants.
Some chemical manufacturers have a cleaning kit avail-
able for purchase. It usually includes a chemical container
with hose connections, hose, chemical pump, lter, and
other miscellaneous items. You could also make up your
own kit. A Technicold TE500 pump is a good quality,
chemical resistant, submersible pump that can be used
for this purpose. When using any pump for cleaning, a
strainer/lter/screen must be installed on the inlet of the
pump to prevent debris from damaging the impeller.
The container should be of sucient volume for the
chemical/water mix required. The chemical pump can be
placed outside of the container. A bulkhead tting would
be installed in the side of the container and a hose con-
nected from it to a strainer, then to the inlet of the pump.
Connect a hose from the discharge of the pump to the
inlet of the coil/manifold/piping to be cleaned. Another
hose goes from the outlet of the coil/manifold/piping back
into the bucket. If using a submersible pump a bulkhead
tting is not needed. The pump can be placed directly in
the container with a strainer/lter/screen attached to the
inlet. Check the ltration on the inlet of the pump regu-
larly and clean as needed.
Make sure that any materials used (container, hoses, t-
tings, pump, etc.) to ush the system are compatible with
the chemical used.
Use caution when mixing the chemical and water that you
do not splash it on yourself or the surrounding area.
Once you have set up your cleaning kit it should be oper-
ated with fresh water to check for leaks prior to adding the
chemical mix. Protect the area where you are working to
prevent damage from splashing or spilled chemical.

Condenser Coil & Raw Water System Cleaning
(continued)
There are two methods used for cleaning a system. The
"Immersion Method" and the "Open Loop Recirculation
Method". Immersion cleaning requires the system to be
lled with the water/chemical mix and left to dissolve
the internal growth/contamination for an extended period
of time. It is the least eective of the two methods and
should be considered only if there is a blockage in the
system that stops the ow of liquid. Open loop recircula-
tion method pumps the mix through the system. It is cap-
tured back into the container where the mix is drawn from
by the recirculation pump. This continuous ow through
the system is the most eective method of cleaning.
When the system is chemically cleaned a forward-ush
and back-ush procedure should be performed. To
forward-ush the water/chemical mix is pumped into the
bottom connection and discharges from the top connec-
tion back into the container. This will be the same ow
direction as the normal raw water ow. It will ll the
coil/manifold/piping with the mix so that all surfaces
are wetted. After the cleaning procedure is done the ow
should be reversed and the system back-ushed with the
mix. Pump pressure in addition to gravity will remove any
larger debris that may be left in the system back into the
container.
It is very important that whenever a system is chemically
cleaned that it must be ushed with fresh water for a mini-
mum of 10 minutes to remove residual chemical.
Every chemical manufacturer provides dilution ratios and
gallons of chemical required for the size system that you
have. They also have recommended cleaning times for
average or heavy fouling of the system. Some chemicals
have color indication or test strips to monitor strength
of the solution so that you know when to add more or
replace as needed. A visual inspection inside the chemi-
cal container will also give and indication if the system is
clean. If no more debris is seen entering the container then
it is probably clean.
Upon completion of the cleaning routine and ushing
with fresh water the system should be put back online.
The pressures, amperages and temperatures should be
taken again. If they are still operating high then additional
cleaning may be needed.
It should be noted that on smaller systems the raw water
pumps may have a magnetic drive impeller. This station-
ary impeller may be restrictive to the ow of the solution
during cleaning and it is recommended that it be removed
until the cleaning process is complete. Don't forget to
re-install it prior to doing the post-cleaning system check.
Make sure there is no debris inside the impeller housing
prior to installing the impeller.
When you have a situation where the condenser coil
needs cleaning, do not assume that it is the only part of
the system that is fouled up. Even if the raw water strainer
looks clean the piping and manifold can also be dirty. A
visual inspection of the inside of the piping and manifold
should be done at the time of the cleaning or fresh water
back-ushing.
