8.2 Condensate Drains
WARNING!
Do not terminate condensate drain line
!
– within 1 m 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.
Mind the following notes on 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.
I
For installation of the condensate drain (fig. 4, page 4):
➤ Remove the aft facing watertight plug (3) from the base pan (2) of the air
conditioning unit using the hose barb (1).
➤ Screw the hose barb into the drain hole and tighten it (4).
➤ Secure the drain hose with a stainless steel hose clamp (5).
➤ Install the condensate drain hose downhill from the unit and to a safe and
proper collection point (6).
The hose should have a trap.
NOTE
•
Two drain fittings may be used and the hoses teed together provided there
is a minimum 50 mm drop from the bottom of the base pan to the tee
connection.
•
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 base pan and check-
ing for good flow.
19
EN
Installation MCS T6, MCS T12, MCS T16
8.3 Blower Assembly
Rotate the blower to allow the most direct flow of air to the supply-air grille
(fig. 5, page 4).
➤ Loosen the adjustment screw (1).
➤ Rotate the blower (2).
➤ Tighten the adjustment screw (1).
8.4 Electrical Box
Mind the following notes on the installation of the electrical box (fig. 8 3,
page 6):
•
Mount the electrical box in a dry location.
•
Mount the electrical box to a flat, solid surface within 1 m of the unit.
•
Mount the electrical box within 4.5 m of the location where the digital control will be installed.
➤ Use the 4 mounting slots in the back of the electric box to attach it to a suita-
ble mounting surface.
➤ Use screws appropriate for mounting surface (not included).
8.5 Supply-Air Grille
Mind the following notes on the installation of the supply-air grille to ensure
direct uninterrupted airflow from the blower:
NOTICE!
In no instance should the supply-air grille discharge be directed towards the
A
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 is required
behind the supply-air grille for attaching the ducting.
➤ Create the cut outs for the supply-air grille according to the following table:
MCS T6 MCS T12 MCS T16
4.9" x 4.9"
125 x 125 mm
➤ Mount the supply-air grille.

9.9" x 5.9"
252 x 150 mm
9.9" x 7.9"
252 x 201 mm
EN
MCS T6, MCS T12, MCS T16 Installation
8.6 Return-air Grille
Mind the following notes on 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 107 mm of clearance in front of
it in the cabin area (fig. 3, page 4).
➤ Create the cut out for the return-air grilles according to the following table:

252 x 201 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 per-
formance and possibly freeze the evaporator coil.
➤ Mount the return-air grille.
8.7 Ducting
Mind the following notes on the installation of the ducting:
•
The ducting should be run as straight, smooth and taut as possible.
•
Avoid any unnecessary bends and loops. Rotate the blower instead.
•
Minimize the number of 90° bends (two tight 90° bends can reduce airflow
by 25 %).
•
Ensure the ducting is properly connected with no excess.
Proceed as follows to install the ducting:
13.9" x 9.9"
353 x 252 mm
13.9" x 9.9"
353 x 252 mm
➤ 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.
➤ 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.
21
EN
Installation MCS T6, MCS T12, MCS T16

•
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.
•
Secure all threaded connections with threaded-sealing tape. Wrap it only
2 to 3 times around it.
•
Tighten one and a half turns beyond hand tight.
WARNING!
•
Do not tighten the threaded connections too firmly. Otherwise cracks may
form within hours or days.
•
Before you start up the boat, check for any leaks. If you are unsure of how to
proceed, contact a qualified ship's mechanic. Otherwise there is a danger
of the boat sinking. This can result in injury or death.

8.10.4 Installation of the Seawater System
➤ Install the seawater speed scoop intake as far below the water line and as
close to the keel as possible and with intake facing forward.
This keeps the intake in the water when the boat heels over so that air does
not get into the system.
➤ Bed the scoop with a marine sealant designed for underwater use.
➤ Apply the bedding compound liberally to both sides and throughout the
hole.
➤ Install the bronze, full flow seacock on the speed scoop thru-hull inlet.
➤ Install the seawater strainer below the level of the pump with access to filter.
➤ Connect the seacock and strainer with an uphill run using the 5/8" (16 mm)
reinforced marine grade hose.
➤ Mount the seawater pump securely above the strainer, at least 300 mm
below the water line.
➤ Mount the air conditioning unit by securing the base pan onto a flat, horizon-
tal surface with the mounting clip brackets and the 4 screws.
The base pan also serves as a condensate pan.
➤ Connect the discharge from the pump uphill to the bottom inlet of the air
conditioning unit’s condenser coil with 5/8 (16 mm) reinforced marine grade
hose.
➤ Install the overboard discharge thru-hull fitting.
➤ Connect the discharge from the condenser coil to the overboard discharge
thru-hull fitting with 5/8" (16 mm) reinforced marine grade hose.
➤ Connect all metallic parts in contact with seawater to the vessel’s bonding
system including
– the speed scoop inlet,
– pump (the harness ground wire),
– the air conditioner.

The following guidelines should be followed during the connection of the
Marine Climate System:
•
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.
•
Use a minimum of 3.5 mm² boat cable
– to supply power to the air conditioning unit
– to supply power to 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.

EN
Operation MCS T6, MCS T12, MCS T16
•
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. 0,
page 8)
➤ 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.
