8.2 Condensate Drains

Warning!

Do not terminate condensate drain line

• within 0.9m of any outlet of engine or generator exhaust systems,

• in a compartment housing of an engine or generator,

• in a bilge, unless the drain is connected properly to a sealed condensate or shower sump pump.

Failure to comply may allow bilge or engine room vapors to mix with the air conditioners return-air and contaminate living areas which may result in injury or death.

The following guidelines should be followed during the installation of the condensate drains:

• Do not route condensate drains to the bilge.
• Run the condensate drain line downward from the unit to a suitable drain location.
  The condensate drain line should have a trap.

For installation of the condensate drain (fig. 3, page 4):

Remove the aft facing watertight plug from the base pan (4) of the air conditioning unit.

Slip the solid washer (2) and the liquid-seal washer (3) onto the PVC fitting (1) in that order.
Connect the PVC fitting (1) through the exposed hole in the base pan (4) with the locking nut (5).
Securely tighten with two wrenches to provide a proper seal.
Attach a 5 / 8'' (16 mm) I.D. reinforced hose to the hose barb and secure with stainless steel hose clamps.

Installation MCS5, MCS15

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

The hose should have a trap.

Note:

Two drain fittings may be used and the hoses teed together provided there is a minimum 51 mm drop from the bottom of the base pan to the tee connection.

Note:

Consideration should be given to installing a trap in the condensate drain line(s) so that normal discharge of condensate can fill the trap and prevent the ingress of carbon monoxide (CO) or other potentially harmful vapors.

Test the installation by pouring one liter of water into the pan and checking for good flow.

8.3 Blower Assembly

Horizontal or vertical supply-air discharge may be achieved by rotating the blower (fig. 4 1, page 4). Rotate the blower to allow the most direct flow of air to the supply-air grille

8.3.1 MCS5

Remove wire tie holding blower wire harness to base pan and/or adjacent harness.
Remove and save the 7 screws (fig. 4 5, page 4) holding the blower plate to the evaporator shroud.
Rotate the blower 90^ so the discharge is in the vertical position and aimed upward.
Reinstall the 7 screws to hold the blower plate to the evaporator shroud.
Make sure the power wire is repositioned so it will not catch on anything during or after installation.
The vertical rotation is complete.

8.3.2 MCS15

The auxiliary vertical-support bracket must be used when the blower is vertical or unit damage will occur, voiding the warranty.

Remove and discard the 2 self-tapping screws that attach the blower to the drain pan.
Remove wire tie holding blower wire harness to base pan and/or adjacent harness.
Remove and save the 7 screws (fig. 4 5, page 4) holding the blower plate to the evaporator shroud.

Rotate the blower 90^ so the discharge is in the vertical position and aimed upward.
Reinstall the 7 screws to hold the blower plate to the evaporator shroud.
Locate the auxiliary vertical support bracket (fig. 4 3A and 3B, page 4) attached to the pan.
Remove and save the 2 screws (fig. 4 2, page 4) in the end A (fig. 4 3A, page 4).
Remove and save the 2 self-tapping screws (fig. 4, page 4) that attach blower to drain pan.
Using the 2 screws you just removed from the end A, mount the end A to the inside of the pan (fig. 4 6, page 4).

Note

Self-tapping screws will drill their own pilot holes if a screw gun is used, but if pilot holes are necessary, utilize a 0.5mm drill bit with a drill stop or other method to block the drill bit from going deeper than 6mm into the blower housing, as the fan blade will be damaged.

Using 2 of the self-tapping screws you just removed, mount the end B (fig. 4 3B, page 4) of the bracket to the blower housing (fig. 4 7, page 4).
Make sure the power wire is repositioned so it will not catch on anything during or after installation.
The vertical rotation is complete.

8.4 Electrical Box

The following guidelines should be followed during the installation of the electrical box:

• Mount the electrical box in a dry location.
• Mount the electrical box to a solid surface within 1m of the unit.
• Mount the electrical box within 4.5m of the location where the digital control will be installed.
  Use the 3 keyhole mounting slots in the back of the electric box to attach it to a suitable mounting surface.
  Use screws appropriate for that mounting surface (not included).

8.5 Supply-Air Grille

The following guidelines should be followed during the installation of the supply-air grille to ensure direct uninterrupted airflow to the evaporator:

Caution! In no instance should the supply-air grille discharge be directed towards the return-air grille, as this will cause the system to short cycle.

Install the supply-air grille as high as possible.
- A minimum clearance of 76~mm plus the duct diameter size (fig. 6 3, page 6) is required behind the supply-air grille for attaching the ducting (fig. 2 11, page 3).

Create the cut outs for the round supply-air grille according to the following table:

MCS5 MCS15
4,4 x 4,4" 112 x 112 mm	9.6 x 7.6" 254 x 204 mm

Mount the supply-air grille.

8.6 Return-air Grille

The following guidelines should be followed during the installation of the return-air grille to ensure direct uninterrupted airflow to the evaporator:

• Install the return-air grille as low and as close to the unit as possible.
• Install the return-air grille away from exhaust and bilge vapors.
• The return-air grille should have a minimum of 107mm of clearance in front of it in the cabin area.

Create the cut out for the return-air grilles according to the following table:

MCS5 MCS15
9.6 x 7.6"244 x 194 mm	13.6 x 9.6"346 x 244 mm

If your kit is supplied with a filtered return-air grille: Remove the filter attached to the unit's evaporator and discard it.
Two filters are not better than one, as the reduced air flow will decrease performance and possibly freeze the evaporator coil.

Mount the return-air grille.

8.7 Ducting

The following guidelines should be followed during the installation of the ducting:

• The ducting should be run as straight, smooth and taut as possible.
• Avoid any unnecessary bends and loops.
• Minimize the number of 90^ bends (two tight 90^ bends can reduce airflow by 25% ).
• Ensure the ducting is properly connected with no excess.

The following is a summary of proper ducting connections:

Start at either end (the air-discharge grille or the air conditioning unit).
Pull back the fiberglass insulation exposing the inner mylar duct hose.
Slide the inner mylar duct hose around the mount ring until it bottoms out.
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.

Installation MCS5, MCS15

Wrap duct tape around the ducting and ring joint to prevent any air leaks.
Pull the insulation back up over the mylar to the ring and tape this joint.
Run the ducting to the other end, keeping it as straight, smooth, and taut as possible.
Remove excess ducting.
Use the same connection method at the other end.

8.8 Control Panel Installation

The following guidelines should be followed during the installation of the control panel:

• Mount the control panel within 4.5m of the electrical box.
• Mount the control panel on an inside wall, slightly higher than mid-height of the cabin, in a location with freely circulating air where it can best sense average temperature.
• Do not mount the control panel

-in direct sunlight,
- near any heat producing appliances
- in a bulkhead where temperatures radiating from behind the panel may affect performance
- in the supply-air stream
- above or below a supply or return-air grille

Before mounting the control panel, consider the location:

Create a cut out size for the control panel: 64~mm wide by 48~mm high.
Plug one end of the display cable (8-pin RJ-45 connector) into the display socket (J-2) of the electric box and the other end into the back of the control panel.
Prior to placement clean the mounting surface with isopropyl alcohol only (test alcohol on hidden portion of surface first).

Secure the control panel to a bulkhead with the adhesive strips provided.

• Ensure the water is flowing freely from overboard discharge while the pump is running.
• The speed scoop intake must face forward and not be shared with any other pump.
• The speed scoop and the shut off valve must be tight and properly sealed.
• A seawater strainer (3) is mandatory between the shut off valve (seacock) (1) and the pump (4) to protect the pump from any foreign matter.
• Ensure access to the filter of the strainer (3).
• The seawater system should be installed
• with an upward incline from the speed scoop and seacock (1),
• through the strainer (3),
• to the inlet of the pump (4) and

• then up to the inlet of the air conditioning unit's condenser coil

• The discharge from the air conditioning unit (5) should run to the seawater outlet thru-hull fitting (6) which should be located where it can be visually checked for water flow and as close as practicable to the waterline to reduce noise.

• Ensure the hose runs uphill from speed scoop to strainer (3), pump (4) and air conditioning unit (5).
• Avoid loops, high spots or the use of 90^ elbows with seawater hose.
• The air conditioning unit (5) should be installed as low as possible, but never in the bilge or engine room areas (such as under a V-berth, dinette seat or bottom of a locker).
• Ensure proper spacing around unit.
• Ensure that the selected location is sealed from direct access to bilge and/or engine room vapors.
• Mount the unit (5) on a firm, level, horizontal surface.
• Double clamp all hose connections with stainless steel clamps, reversing the clamps.
• Use teflon tape on all threaded connections.
• Tighten one and a half turns beyond hand tight.

• The correct size circuit breaker should be used to protect the system as specified on the air conditioning unit's data plate label.
• Install and ground/bond AC power source in accordance with marine electrical standards.

Connecting the Marine Climate System MCS5, MCS15

• Use a minimum of 3.5 ~mm^2 boat cable

• to supply power to the air conditioning unit

• to supply powerto the seawater pump
  to extend the wires on the pump

• Any electrical connections in the bilge below the waterline should use sealing heat shrink type butt splices.

• All connections to the terminal strip shall be made with appropriately sized ring terminals (not supplied).
  Each air conditioning unit installed requires its own dedicated circuit breaker.

• If there is only one air conditioning unit installed, the seawater pump does not require a circuit breaker; the wiring from the seawater pump is connected to the terminal strip on the unit (see wiring diagram, fig. 8, page 7)

• If two or more air conditioning units use the same seawater 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).

Connect the air conditioning unit to the boat's bonding system to prevent corrosion due to stray electrical current.
Ensure that the AC ground of the air conditioning unit is properly connected to the AC ground of the boat.
Within the boat itself, ensure that the AC ground bus is connected to the DC ground bus at exactly one place.

Bond individually all pumps, metallic valves and fittings in the seawater circuit that are insulated from the air conditioning unit by PVC or rubber hoses to the boat's bonding system.

This will help eliminate any possibility of corrosion due to stray current.
