OVERVIEW
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 a/c unit's
efficiency. This a/c unit 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 against the packing list to ensure all cartons
have been received. Move units in the normal "up" orientation as indicated by the arrows on each carton. Examine
cartons for shipping damage, removing the units from the cartons if necessary. 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 three 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 sole 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 unit cannot and should not be mounted in spaces containing gasoline engines,
tanks, LPG/CPG cylinders, regulators, valves or fuel line fittings. Failure to follow this
warning could result in injury or death and violation of federal requirements for ignition
protection.

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. See diagram below.
The unit should be installed as low as possible, BUT NEVER IN THE
BILGE OR ENGINE ROOM AREAS, ENSURE THAT THE SELECTED
LOCATION IS SEALED FROM DIRECT ACCESS TO BILGE AND/OR
ENGINE ROOM VAPORS. Installing the unit as low as possible (such as
under a V-berth, dinette seat or bottom of a locker) and ducting the supply
air as high as possible, creates an ideal airflow condition. This type of
installation will prevent short or premature cycling.
The unit should be positioned on a firm, level, horizontal surface and the
condensate drain line should run downward from the unit to a suitable drain
location. Plan all Connections, which must be made including ducting,
condensate drain, and seawater in and out, electrical power connections,
location of control, and seawater pump placement, to assure easy access
for routing and servicing.
Tools required:
Screws drivers
Pliers
Pipe wrench
Wire cutters / crimpers
Drill & 7/8" bit
Jigsaw
Duct tape
Electrical tape
Teflon tape
Bedding compound to seal thru hull
fittings
Hardware to secure unit, pump,
strainer, grilles & control panel

CONDENSATE DRAINS
The condensate drain pan is 2” (50mm) high with two drain locations. During conditions of high humidity,
condensate may be produced at a rate of approximately a 1/2 gallon per hour (1.9 liters per hour). With this in mind,
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 proper 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.
●Two drain fittings may be used and the hoses (teed) together using 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. It is ideal for tight installations as 180° 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.
MOUNTING BRACKETS
The a/c 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.
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 upward. The return air grille should be installed as low and close to the a/c
unit as possible to ensure 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.

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°
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 (r2) and multiply that number by 3.1416(π). The following is a
summary of proper 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 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.
●Insulated when located in high heat load areas (hull side, mechanical compartments, etc.).
●Be properly protected against potential damage when routed through open areas or bulkheads.
SEAWATER PUMP AND PLUMBING
Several guidelines are required during the installation of the seawater system. Since the circulation pump is
centrifugal, 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 a/c unit's condenser coil. The discharge from the a/c 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. Hose connections must be secured using double/reversed stainless steel hose clamps. Use Teflon

Operation / Installation Manual –FCF 5,000, 9,000, 12,000, 16,000
Page 10
tape on all threaded connections.
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 a/c 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 Teflon tape 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
All a/c 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 on the a/c
unit's data plate label. A minimum of 12 AWG boat cable should be used to supply power to the a/c unit and the
seawater pump.All connections shall be made with ring or fork terminals. Turn off a/c power supply circuit
breaker before opening electric box.
Each a/c unit installed requires its own dedicated circuit breaker. If there is only one a/c unit 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 a/c units 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 withABYC electrical codes. Power to the unit must be within
the operating voltage range indicated on the data plate. Properly sized fuses or HACR circuit breakers must be
installed for circuit protection. See data plate for maximum fuse/circuit breaker size (MFS) and minimum circuit
amperage (MCA). All units must be effectively grounded to minimize the hazard of electrical shock and personal
injury. The following can be observed: AC (alternating current) grounding (green wire) must be provided with the
AC power conductors and connected to the ground terminal (marked "GRND") at the AC power input terminal
block of the unit(s), 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 a/c 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 a/c unit by PVC or rubber hoses must be individually bonded
to the vessels bonding system also. This will help eliminate any possibility of corrosion due
to stray current or voltage.
3 PHASE NOTICE
It is extremely important to ensure that wiring and phase sequencing of a three-phase power source is correct.
Marine wiring standards call for power source phases L1, L2, and L3 to be color-coded BLACK, WHITE, and RED,
respectively. These must be connected to the unit with the proper sequence; otherwise, it will not operate properly.
If the wiring sequence is incorrect, the unit's compressor (Scroll type only) and pump (if applicable) will run in the
reverse direction at a significantly increased noise level.

DO NOT turn the unit off and immediately turn it back on. Wait at least 30 seconds for
refrigerant pressures to stabilize.
Before mounting the wired display, consider the location. The display
panel should be mounted on an inside wall, slightly higher than
mid-height of the cabin. The cut out size for the display panel is 2 1/2”
(64mm) wide by 3 5/16” (84mm). Do not mount the display in direct
sunlight, near any heat producing appliances or in a bulkhead where
temperatures radiating from behind the panel may affect
performance. Do not mount the display in the supply air stream. Do
not mount the display above or below a supply or return air grille. Do
not mount the display behind a door, in a corner, under a stairwell or
any place where there is no freely circulating air. Mount the display
within display cable length (custom lengths available) of the air
conditioner. Plug the display cable into the circuit board in the electric
box and into the back of the display panel.
CONTROL BOX INSTALLATION
Mount the control box using four M5 screws.
