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.

CAUTION: When unpacking and installing the 2 knob control, care must be taken not to kink or break the copper cap tube when uncoiling the sensing bulb. The cap tube is hollow and kinking or sharp bends will inhibit system operation.

SAFETY CONSIDERATIONS

Never install your air conditioner in the bilge or engine room areas. Insure that the selected location is sealed from direct access to bilge and/or engine room vapors. Do not terminate condensate drain line within four (4) feet of any outlet of engine or generator exhaust systems, nor in a compartment housing an engine or generator, nor in a bilge, unless the drain is connected properly to a sealed condensate or shower sump pump.

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 codes. 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:

! WARNING TO MINIMIZE THE HAZARD OF ELECTRICAL SHOCK AND PERSONAL INJURY, THIS COMPONENT MUST BE EFFECTIVELY GROUNDED. REFER TO THE INSTALLATION GUIDELINES FOR FURTHER INFORMATION.

PLACEMENT OF SYSTEM

Selecting a good location for your air conditioner is the most important part of your preparations. 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 diagram below shows the Cool Mate 5K unit with a single duct application. Refer to the back of this manual for a dual duct installation drawing, used with the 12K unit only.








The COOL MATE unit should be installed as low as possible, BUT NEVER IN THE BILGE OR ENGINE ROOM AREAS. INSURE 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 air flow 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, sea water in and out, electrical power connections, location of control, and sea water pump placement, to assure easy access for routing and servicing.

SPACING ALLOWANCES & UNIT DIMENSIONS

The following space allowances should be considered when mounting the unit:

1) Allow a minimum of 6" around the perimeter of the unit in the area of the sea water and condensate drain piping.

2) Allow a minimum of 3" of air space in front of the evaporator coil for the return air intake if it is adjacent to a bulkhead.

3) Allow a minimum of 3" of air space for the electric blower motor ventilation.

4) For flexible ducting connection, allow 2" for the duct ring, 1" for the duct bend radius and add 4" or 6" for the diameter of the ducting to get the total distance as measured from the blower outlet. In other words, 7" or 9" of clearance, depending on unit, is needed for the ducting connection (this also applies to clearance needed behind the supply air grille). Note that the blower and duct ring can be positioned either vertically or horizontally (see diagram below).

 

The above dimensions are suggested minimums. Enough space should be allocated for installation and serviceability. Below dimensions are for the 5K unit and the 12K unit as specified.

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 sea water pump circulates cool sea water 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 sea water and discharged overboard. The liquid refrigerant is then passed through the EVAPORATOR COIL and the cycle repeats. Removing heat from the cabin air lowers its temperature. The cooled air is blown through the ducting and out the supply air grille(s).

COOL MATE OVERVIEW

MOUNTING BRACKETS

The a/c unit is supplied with a base pan which also serves as a condensate pan. Mounting clip brackets and screws (4) are provided to secure the base pan onto a flat, horizontal surface.

CONDENSATE DRAINS

The condensate drain pan is 1¾" high with two drain locations. During conditions of high humidity, condensate may be produced at a rate of approximately ½ gallon 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 a quart of water into the pan and checking for good flow.

For installation of the condensate drain:

1. Remove the aft facing watertight plug from the base pan of the a/c unit.

2. Slip the solid washer and the liquid-seal washer onto the PVC fitting in that order.

3. Connect the fitting through the exposed hole in the base pan with the locking nut.

4. Securely tighten with two (2) wrenches to provide a proper seal.

5. Attach a " I.D. reinforced hose to the hose barb and secure with stainless steel hose clamps.

6. Install the condensate drain hose downhill from the unit and aft to a sump.

7. Two drain fittings may be used and the hoses teed together provided there is a minimum 2" drop form the bottom of the base pan to the tee connection.

NOTE: DO NOT TERMINATE CONDENSATE DRAIN LINE WITHIN FOUR (4) FEET OF ANY OUTLET OF ENGINE OR GENERATOR EXHAUST SYSTEMS, NOR IN A COMPARTMENT HOUSING AN ENGINE OR GENERATOR, NOR IN A BILGE, UNLESS THE DRAIN IS CONNECTED PROPERLY TO A SEALED CONDENSATE OR SHOWER SUMP PUMP.

BLOWER ASSEMBLY

With the COOL MATE, you can achieve horizontal or vertical supply air discharge by rotating the blower to the desired orientation. Its design allows the blower to be rotated by removing the screws holding the blower plate to the evaporator coil shroud. Rotate the blower to allow the most direct flow of air to the supply air grille.

SUPPLY & RETURN AIR GRILLES

As previously indicated, install the supply air grille(s) as high as possible and the return air grille as low and close to the COOL MATE as possible to insure direct uninterrupted airflow to the evaporator. The cut out for the 4" supply air grille is 4" in diameter, the flange is 5½" in diameter. The cut out for the rectangular transition box used with the 12K unit is 12½" by 6½". Connect the 6" oblong duct ring to the transition box by first placing the ring on the box and tracing the hole. Cut the oblong hole out of the box. Secure the ring to the box with rivets (trim ¼" from ring flanges if necessary). Completely seal the joint between ring and box with silicone. A minimum of 7" clearance for 4" duct and 9" clearance for 6" duct is required behind the grille for attaching the ducting. The return air filter, mounted to the front of the evaporator, removes debris from the air prior to the air being drawn across the evaporator coil and fins. Dust and lint can clog and reduce air flow across the evaporator coil resulting in poor performance. See MAINTENANCE section for filter cleaning instructions.

DUCTING

Good air flow 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 as possible minimizing the number of 90 degree bends. Two tight 90 degree bends can reduce airflow by 25%.

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. 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.

 

2 KNOB MANUAL CONTROL PANEL (2KB MCP)

The 2 knob MCP should be located within 10' (cap tube length) of the COOL MATE unit. The cut out size for the MCP is 2.5" wide by 4.5" tall. Once the cut out is made, route the control wires and the cap tube with return air sensor (copper bulb) through the hole and back to the unit using caution not to kink the cap tube. Slide the sensor into the mounting loops provided on the evaporator coil. Make electrical connections to the electrical box mounted on the unit. See OPERATION section for instructions.

ELECTRICAL CONNECTIONS

All Cool Mate units have a five position terminal strip mounted on top of the electrical box. The terminal strip is labeled for proper connections of the electrical supply, ground wires and pump circuits. Wiring diagrams are provided in the electrical box and in this manual. 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 to the sea water pump (see next paragraph). All connections to the terminal strip shall be made with ring terminals supplied with the Cool Mate kit. Turn off a/c power supply circuit breaker before opening electrical box and accessing the terminal strip.

Each a/c unit installed requires its own dedicated circuit breaker. If there is only one a/c unit installed, the sea water pump does not require a circuit breaker, the wiring from the sea water pump is connected to the terminal strip on the unit. A minimum of 12 AWG boat cable should be used to extend the wires on the pump, if necessary, using the butt slices included with the kit. If two or more a/c units use the same sea water pump, the pump wires will be connected to a pump relay panel (PRP) which in turn has its own dedicated circuit breaker (see the wiring diagram furnished with the PRP). Any electrical connections in the bilge below the waterline should use heat shrink type butt splices.

INVERTER APPLICATION WITH THE COOL MATE 5K

An inverter is essentially the reverse of a battery charger, it converts 12VDC power into 115VAC power through the use of electrical circuitry and a step up transformer. When using an inverter in an air conditioning application, the compressor locked rotor (start-up) amperage determines the peak power output required and therefore the size of the inverter. The continuous power requirement of the air conditioner, the output of the alternator and the capacity of the selected batterie(s) determines the available run times.

To choose an inverter for your application, there are several characteristics you should consider. A minimum of 3300 watts of peak power is required. You should choose a larger inverter if you plan on utilizing any other AC equipment while the air conditioner is running. Remember that the Cool Mate 5K compressor will cycle on and off, briefly using the peak capacity with every restart. Specific inverter characteristics such as battery charging capability, voltage frequency and physical size should also be considered. The Cool Mate 5K has been tested and approved for use with both line frequency and high frequency inverters. The continuous current required to run the Cool Mate 5K and a sea water pump is 4.7 amps (measured at 88ºF sea water and 82ºF free air return with standard 115VAC commercial power).

Storage batteries should maintain a full charge on standard 55 amp alternators. Do not use your normal starting battery to power the inverter! Utilizing three small storage batteries in parallel will result in longer endurance than one large storage battery of equal capacity due higher efficiencies at lower currents. Proper battery cable and terminal sizes are critical for both safety and efficiency. The Cool Mate 5K will draw between 40 and 50 amps DC depending on the battery charge and other ambient conditions.

Note: Inverter use is not practical with the Cool Mate 12K unit.

NOTICE:

Field wiring must comply with ABYC (American Boat and Yacht Council) electrical standards. Power to the unit must be within the operating voltage range indicated on the data plate. Properly sized fuses and circuit breakers must be installed for branch circuit protection. See equipment rating plate for maximum size. All a/c units must be effectively grounded to minimize the hazard of electric shock and personal injury. The following standards apply: 1. 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.

2. 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.

3 When servicing or replacing existing equipment containing a chassis-mounted "ground" stud, the service person or installer must check the vessel's wiring for the existence of the connection required in item 2 above. ABYC standards are available from:

SEA WATER PUMP AND PLUMBING

Several guidelines should be followed during the installation of the sea water system. Since the circulation pump is centrifugal and not self-priming, it must be mounted so that it is always at least one foot 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 sea water speed scoop intake as far below the water line and as close to the keel as possible in any application, but especially on a sail boat, 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 sea water strainer is mandatory between the shut off valve (sea cock) and the pump to protect the pump from any foreign matter. Failure to install a sea water strainer will void the pump warranty. The sea water system should be installed with an upward incline from the speed scoop & sea cock, through the strainer, to the inlet of the pump and then up to the inlet of the a/c unit's condenser coil. The discharge from the a/c unit should then run downhill to the sea water outlet through hull fitting which must be located above the water line. All hose connections shall be secured by means of double/reversed stainless steel hose clamps. Use teflon tape on all threaded connections.

The following is a summary of the sea water 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 sea cock on the speed scoop thru-hull inlet.

3. Install a sea water strainer below the level of the pump with access to filter.

4. Mount the pump above the strainer and at least one foot below the waterline.

 

5. Connect the sea cock and strainer with an uphill run of " 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 " hose. Connect the discharge from the condenser coil downhill to the overboard discharge thru-hull fitting with " hose.

7. Avoid loops, vertical bends (high spots) or the use of 90º elbows with sea water 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 sea water to the vessel's bonding system including

the speed scoop inlet, strainer, pump and the air conditioner.

MAINTENANCE

Seawater Strainer

Insure that your pump receives adequate sea water flow by regularly cleaning the strainer basket. Periodically check the overboard discharge for a steady stream of water. Check sea water intake speed scoop for obstructions. Make sure hoses are not looped, kinked or crushed.

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.

Winterization

There are several methods of winterization, some of which work better than others. The four various methods employed using a 50/50 non-polluting biodegradable anti-freeze/water solution are:

1. Pumping of anti-freeze solution into the overboard thru-hull fitting, and discharging through the intake thru-hull fitting.

2. Use of the sea water pump to pump anti-freeze solution through the system and discharging through the overboard thru-hull fitting. Close sea cock, remove hose from strainer discharge, raise hose above pump (so pump does not lose its prime) and pour in anti-freeze solution. Pump solution through system. The strainer and hose to sea cock will also need to be drained of water.

3. Use of pressurized air injected at the overboard discharge fitting and the water being discharged through the sea water intake fitting.

4. Use of pressurized air to force water from the intake through the overboard discharge.

Note: Collect all discharged liquids and recycle or dispose of in a proper manner.

Any method which causes the anti-freeze solution to flow downward is the method of choice. By this means, the anti-freeze solution will displace any water trapped and eliminate the possibility of freezing in hidden areas.

In addition, since the sea water pump utilizes a magnetically driven impeller, the impeller should be removed from the wet end assembly, wiped with an alcohol solution, and stored in a warm, dry area until commissioning takes place.
