Overview
All units are manufactured without service ports
HOW IT WORKS
Your self-contained air conditioner consists of four main components and a refrigerant gas circulating through the system.
The BLOWER draws warm cabin air across the fins on the EVAPORATOR where the heat from the air is transferred to
the refrigerant in the evaporator coil. As the refrigerant evaporates from a liquid into a gas, it absorbs the heat from the
cabin air. The COMPRESSOR then compresses the refrigerant gas and pumps it through the outer tube in the
CONDENSER COIL. The seawater pump circulates cool seawater through the inner tube in the condenser coil; this
cools the refrigerant and condenses it into a liquid. The heat from the refrigerant is exchanged to the seawater and
discharged overboard. The liquid refrigerant is then passed through the EVAPORATOR COIL and the cycle repeats;
removing heat from the cabin air lowering its temperature. The cooled air is blown through the ducting and out the supply
air grille(s). For reverse cycle heating, the refrigerant flows in the opposite direction through the reversing valve. Heat is
transferred from the seawater in the condenser coil to the refrigerant and then to the air blowing through the evaporator
into the cabin. Seawater temperature will directly affect the air conditioners efficiency. This air conditioner can effectively
cool your boat in water temperatures up to 90°F and heat in water temperatures as low as 40°F.

Installation
Unpacking and Inspection
When the equipment is received, all items should be carefully checked according to the packaged components list within
this manual to ensure all components have been received. Examine components for shipping damage. If the unit is
damaged, the carrier should make the proper notation on the delivery receipt acknowledging the damage.
Safety Considerations
VERY IMPORTANT: Never install your air conditioner in the bilge or engine room areas. Ensure that the selected location
is sealed from direct access to bilge and/or engine room vapors. Do not terminate condensate drain line within 3’ (914mm)
of any outlet of engine, generator exhaust system, compartment housing an engine or generator, or in a bilge, unless the
drain is connected properly to a sealed condensate or shower sump pump. Seal all cabin penetrations around
condensate hoses to eliminate harmful bilge fumes in the cabin living spaces.
Installation and servicing of this system can be hazardous due to system pressure and electrical components. When
working on this equipment, always observe precautions described in the literature, tags and labels attached to the unit.
Follow all safety precautions. Wear safety glasses and work gloves and place a fire extinguisher close to the work area.
The following is a summary of the labels on the unit:
Indicates an imminently hazardous situation which, if not avoided, will result in death or serious
injury.
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious
injury.
Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate
injury.
Special note. Make sure to read before proceeding.
Electrical shock hazard. Disconnect voltage at main panel or power source before opening
any cover. Failure to comply may result in injury or death.
This component does not meet federal requirements for ignition protection. Do not install in
spaces containing gasoline engines, tanks, LPG/CPG cylinders, regulators, valves or fuel line
fittings. Failure to comply may result in injury or death.
Notice the 115V series and the 230V series are charged with Hydro fluorocarbon (HFC) refrigerant
R410A. Effective July 1, 1992, it shall be unlawful for any person to knowingly vent or otherwise
knowingly release any class 1 (CFC) or class 2 (H CFC) substance as a refrigerant in a manner
which permits such substance to enter the atmosphere per the clean air act of 1990. Public law
101-549 title IV section 608-c. Failure to comply may result in severe penalties, including fines and
imprisonment.
To minimize the hazard of electrical shock and personal injury, this component must be
effectively grounded. Refer to the installation guidelines for further information. Caution! High
compressor temperature is normal. Do not touch!

Placement of System
Selecting a good location for your air conditioner is the most important part of your preparation. Be sure to consider the
size of the area you are cooling, the air distribution needs, and the size of the unit you have chosen. Keeping in mind that
cool air has a tendency to fall; it is highly recommended that you locate the supply air grille as high as possible in the
cabin. The ducting should be run as straight, smooth and taut as possible minimizing the number of 90 degree
bends. See diagram below.
Size of Sealed room
Ensure the area which the air conditioner is located is not too small otherwise it will affect proper operation. See the
diagram below.

Condensate Drains
The condensate drain pan is 2” (50mm) deep with four drain locations. During conditions of high humidity, condensate
may be produced at a rate of approximately 1/2 gallon per hour (1.9 liters per hour). It is important to route condensate
drains downward to a sump pump. It is not recommended to route condensate drains to the bilge. After the condensate
drain installation is complete, test the installation by pouring water into the pan and checking for good flow.
For installation of the condensate drain:
●
Attach a 5/8” I.D. reinforced hose to the hose barb and secure with stainless steel hose clamps.
●
Install the condensate drain hose downhill from the unit and aft to a sump.
●
Four drain fittings may be used and the hoses joined together with a tee fitting provided there is a minimum 2"
drop from the bottom of the base pan to the tee connection.
Do not terminate condensate drain line within three 3’ (914mm) of any outlet of engine, generator exhaust
systems, compartment housing an engine or generator, nor in a bilge, unless the drain is connected
properly to a sealed condensate or shower sump pump. Seal all condensate hose penetrations.
Blower Assembly
You can achieve multi-directional supply air discharge from a single unit by rotating the blower to the desired position in
45° increments. It is ideal for tight installations as 360° of rotation is available with which to position the blower. Its
advanced design allows the blower to be easily removed for rotating or servicing by removing 4 screws. Rotate the
blower to allow the most direct flow of air to the supply air grille.
After the blower has been properly positioned, make sure to install the supplied
strip of insulation foam around the collar to prevent condensation build up.
Mounting Brackets
The air conditioning unit is supplied with a base pan that also serves as a
condensate pan. Mounting clip brackets (4) are provided to secure the base pan to
a flat, horizontal surface. Hardware for the mounting clips must be provided by the
installer as needed.
Supply & Return Air Grilles and Transition Boxes
Install the supply air grille as high as possible in a location that will provide uniform air distribution throughout the cabin.
Grille louvers should be directed properly for best air flow. The return air grille should be installed as low and close to the
air conditioner as possible to insure direct uninterrupted airflow to the evaporator. The return air grille should have a
minimum four inches (4') of clearance in front of it, free from any furniture or other obstructions. In no instance should a
supply air discharge be directed towards a return air grille, as this will cause the system to short cycle. Allow for adequate
clearance behind the supply air grille(s) for the transition box and ducting connection. See the Maintenance section of
this manual for return air filter cleaning instructions.

Operation / Installation Manual – FCF 5000, 9000, 12000, 16000, 24000
Ducting
Good airflow is critical for the performance of the entire system. It is highly dependent on the quality of the ducting
installation. The ducting should be run as straight, smooth and taut as possible minimizing the number of 90 degree
bends (two tight 90° bends can reduce airflow by 25%). If a transition box is used, the total area of supply air ducts going
out of the box should at least equal the area of the supply duct feeding the box. To calculate the square inch area of a
round duct, multiply the radius by itself (r ) and multiply that number by 3.1416(π). The following is a summary of proper
2
ducting connections:
1. Pull back the fiberglass insulation exposing the inner Mylar duct hose.
2. Slide the Mylar duct hose around the mount ring until it bottoms out.
3. Screw 3 or 4 stainless steel sheet metal screws through the duct hose into the transition ring. Make sure to
catch the wire in the duct hose with the heads of the screws. Use finish washers with the screws if necessary.
Do not use band clamps, as the hose will slide off.
4. Wrap duct tape around the ducting and ring joint to prevent any air leaks.
5. Pull the insulation back up over the Mylar to the ring and tape this joint.
6. Remove excess ducting and use the same connection method at the supply air grille.
All ducting should:
●
Be insulated and appropriately sized for each application.
●
Run as smoothly and taut as possible.
●
Have as few bends or loops as possible.
●
Be securely fastened to prevent sagging or chafing during vessel operation.
●
Have all excess ducting lengths trimmed off.
●
Not be flattened or kinked.
●
Be properly protected against potential damage when routed through open areas or bulkheads.
Seawater Pump and Plumbing
Several guidelines should be followed during the installation of the seawater system. If the circulation pump is centrifugal
and not self-priming, it must be mounted so that it is always at least 1’ (305mm) below the water line regardless of which
tack the vessel is on. Pump may be mounted horizontally or vertically, however, the discharge must always be above the
inlet. Pump head should be rotated toward the direction of water flow. Install the seawater speed scoop intake as far
below the water line and as close to the keel as possible in any application, but especially on a sailboat, to keep
the intake in the water when the boat heels over so that air does not get into the system. The speed scoop intake
must face forward and not be shared with any other pump. A seawater strainer is mandatory between the shut off valve
(seacock) and the pump to protect the pump from any foreign matter. Failure to install a seawater strainer will void the
pump warranty. The seawater system should be installed with an upward incline from the speed scoop & seacock,
through the strainer, to the inlet of the pump, next to the inlet of the air conditioning unit's condenser coil. The discharge
from the air conditioning unit should run to the seawater outlet thru-hull fitting that should be located where it can be
visually inspected for water flow as close to the waterline to reduce noise. All hose connections should be secured using
double/reversed stainless steel hose clamps. Use thread sealer on all threaded connections.
Page 10
Operation / Installation Manual – FCF 5000, 9000, 12000, 16000, 24000
Summary of the seawater system installation:
1. Install the speed scoop thru-hull inlet as close to the keel and as far below the water line as possible, facing
forward. Bed the scoop with a marine sealant designed for underwater use.
2. Install a bronze, full flow seacock on the speed scoop thru-hull inlet.
3. Install a seawater strainer below the level of the pump with access to filter.
4. Mount the pump above the strainer and at least 1’ (305mm) below the waterline.
5. Connect the seacock and strainer with an uphill run of 5/8" reinforced marine grade hose.
6. Connect the discharge from the pump uphill to the bottom inlet of the air conditioning unit's condenser coil with
5/8" hose. Connect the discharge from the condenser coil to the overboard discharge thru-hull fitting with 5/8"
hose.
7. Avoid loops, high spots or the use of 90° elbows with seawater hose (each 90° elbow is equivalent to 2.5'
(762mm) of hose and a 90° elbow on the pump outlet is equivalent to 20' (6.1m) of hose).
8. Double clamp all hose connections with stainless steel clamps, reversing the clamps.
9. Use thread sealer on all threaded connections.
10. Connect all metallic parts in contact with seawater to the vessel's bonding system including the speed
scoop inlet, strainer, pump and the air conditioner. Failure to do so will void warranty.

Electrical Connections, Grounding and Bonding
Turn off air conditioner power supply circuit breaker before opening electric box.
All air conditioner units have a terminal strip mounted inside the electric box. The terminal strip is labeled for proper
connections of the electrical supply, ground wires and pump circuits. A wiring diagram is provided in the electrical box
and later in this manual. The wiring diagram in the electrical box supersedes any found in this manual and ABYC
standards. The correct size circuit breaker should be used to protect the system as specified within the technical
specifications section. A minimum of 12 AWG boat cable should be used to supply power to the air conditioning unit and
the seawater pump. All connections should be made with ring or captive fork terminals.
Each air conditioner installed requires its own dedicated circuit breaker. If there is only one air conditioner installed, the
seawater pump does not require a circuit breaker; the wiring from the seawater pump is connected to the terminal strip in
the electric box. If two or more air conditioners use the same seawater pump, the pump wires will be connected to a
pump relay, Please refer to the wiring diagram. Electrical connections in the bilge and/or below the waterline should use
heat shrink type butt splices. Field wiring must comply with ABYC electrical codes. Power to the unit must be within the
operating voltage range indicated on the data plate. Properly sized marine grade circuit breakers must be installed for
circuit protection. All units must be effectively grounded to minimize the hazard of electrical shock and personal injury.
Make sure to connect the green grounding wire to the GRND stud within the electrical box per ABYC standard E-8, or
equivalent.
1. Connections between the vessel's AC system grounding conductor (green wire) and the vessel’s DC (Direct
Current) negative or bonding system should be made as part of the vessel's wiring, per ABYC standard E-9, or
equivalent.
•
When servicing or replacing existing equipment that contains a chassis-mounted ground stud, the
installer must check the vessel's wiring for the existence of the connection required in item 1 above.
The air conditioner unit must be connected to the ship's bonding system to prevent corrosion
due to stray electrical current or voltage. All pumps, metallic valves and fittings in the seawater
circuit that are isolated from the air conditioning unit by PVC or rubber hoses must be
individually bonded to the vessels bonding system. This will help eliminate any possibility of
corrosion due to stray current or voltage.

Maintenance
Reversing Valves
Reverse cycle units have a reversing valve; the valve must be energized periodically to keep the internal parts moving
freely. To do this, switch the air conditioning unit into heat mode 2-3 cycles per month.
Seawater Strainer
Ensure that your pump receives adequate seawater flow by regularly cleaning the strainer basket. Periodically check the
overboard discharge for a steady stream of water. Check seawater intake speed scoop for obstructions. Make sure
hoses are not looped, kinked or crushed. Check and clean strainer as needed minimum once per month.
Condenser Coil Cleaning (Seawater Acid Flush)
1. With the system turned off at the circuit breaker on the ship's panel, disconnect the inlet and outlet connections
of the condenser coil.
2. Use chemical resistant hoses (PVC 5/8" I.D., etc.) to connect the inlet of the condenser coil to the outlet of a
chemical resistant, submersible pump and let the hose connected to the Coil outlet flow freely into the container
mentioned below.
3. Place a strainer or piece of screen over the inlet of the pump and submerse the pump into a container filled with
a 5% solution of muriatic or hydrochloric acid and fresh water or use a premixed over-the-counter solution. Use a
large container as possible to hold the solution (5-25 gallons). CAUTION: avoid spilling or splashing the solution.
Remember to wear all necessary protective gear, i.e. approved safety goggles and chemical resistant gloves.
Follow all warnings and recommendations given by the manufacturer of any acids or premixed solutions.
4. Power the pump and circulate the solution through the condenser coil for 15-45 minutes depending upon the size
of the coils and the extent of the contamination. Visual inspection of the solution in the container should indicate
when the contamination has been removed.
5. Circulate fresh water through the coil to flush any residual acid from the system.
6. Restart the system and check operational parameters to ensure thorough cleaning has taken place. Additional
cleaning may be necessary with extreme contamination.
7. Minimum once per year or as needed.
For the purpose of protecting the environment, dispose of any contaminated acid solutions in
accordance with federal, state and/or local regulations.
Return Air Filters
Check the return air filter about once a month and clean as necessary. To clean the filter, remove it from the unit, rinse
with water, air dry and reinstall. (Do not used compressed air)

Winterization
There are several methods of winterization, some of which work better than others. There are various methods employed
using a 50/50 non-polluting biodegradable anti-freeze/water solution. Any method that causes the anti-freeze solution to
flow downward is the method of choice. By this, the anti-freeze solution will displace any water trapped and eliminate the
possibility of freezing in hidden areas. In addition, since the seawater pump utilizes a magnetically driven impeller, the
impeller should be removed from the wet end assembly, Wiped with a solution, and stored in a warm, dry area until
commissioning takes place.
Collect all discharged liquids and recycle or dispose of in a proper manner.
