INSTALLATION GUIDE
SAFETY WARNING!
IDo not install the air conditioner in the bilge or engine com-
partment of the boat and make sure that the selected place
is properly blocked from gases and vapours coming from
these spaces.
The air conditioner unit should be placed on a horizontal
surface (e.g. at the bottom of a cabinet or seat) and if pos-
sible it should be raised by 1-2 cm on one side to facilitate drainage of
condensed water from the drain pan. The device can be installed to
the selected place crosswise or lengthwise but it is important to ensure
the continuous air supply of the device and within the condenser unit.
Place the device so that you can have access for future service and
maintenance.
FIXING THE ELECTRICAL BOX
Install the electric box on a dry, at, solid surface within 1 m of the air
conditioning unit. Use the appropriate size of screws to securely x the
electrical box.
INSTALLING THE DISPLAY
Before installing the display observe the following guidelines: Install the
control panel only on a surface that is situated higher than the center
of the cabin and is protected from external and internal heat and light
sources. Only under these conditions the built-in sensor can measure the
cabin temperature accurately.
Do not install the display in a place:
• with direct sunlight,
• near heat producing equipment,
• in a partition wall where there is possible outow of heat behind the panel,
• under or above the air intake or outlet grids.
INSTALLING THE REMOTE TEMPERATURE SENSOR
(optional)
If the display cannot be placed in the correct place to measure accurate
room temperature or if you do not want to measure the temperature in
the cabin where the display is mounted, install the remote sensor that our
basic package contains. The remote sensor will override the heat sensor
built-in the display.
MARINE A/C UNIT DROP WATER DRAIN
The unit produces condensate in COOLING mode which is collected by the
drain pan of the unit. The place of the marine a/c unit should be selected
so that the condensate drainage resulting from operation should be
always ensured. The condensed water collected in the drain pan must be
led through the drain discharge (pipeline) to the bilge of the boat possibly
directly near to the boat’s automatic bilge pump.
If the air conditioner is installed in a place where it is not possible to let the
drain water directly into the bilge then it must be collected and pumped
out. When installing a drain pump unit do not combine the drain pump’s
outlet with the outlets of other systems.
WARNING!
Do not direct the drain pipe to such part of the boat that
does not have a water intake. The method of condensate
discharge diers by ship type therefore removing the
drain water from the boat is not part of the standard marine air con-
ditioning unit.

AIR SUPPLY OF THE UNIT
The proper air supply of the unit is essential for the
operation of the appliance so when installing the air
inlet consider the air volume demand of the certain
type and choose the size of the air inlet according
to the unit’s specications!
During installation keep a minimum distance of
60mm between the unit and the boat’s furniture.
When positioning the unit pay attention to keep the
compressor unit as far from the air inlet as possible
to minimise noise level. The air conditioning unit
may also be placed so that the built-in air inlet is
not in the same air chamber with the unit but in this
case free air ow must be ensured.
WARNING!
Lack of air supply leads to malfunc-
tion or even failure of the unit!

SETTING THE FAN’S AIR OUTLET MOUNTING THE MARINE A/C UNIT
Before installation (if necessary) set the fan in the direction which
allows the most direct airow through the air pipes. The air outlet
direction of the unit’s fan can be adjusted horizontally or verti-
cally. Adjust the air outlet position by loosening the xing screw
and tightly fasten the xing screw after positioning the outlet to
the optimum position. See Figure 3.
The basic package of the unit has 4 mounting brackets. During
installation - if possible - these should be positioned at equal dis-
tance on the edge of the drop pan. See Figure 5. If the space
available allows you mount the unit so that it is 2 cm higher on
one side helping the condensate to drain.

INSTALLING THE AIR DUCT
Unimpeded air ow is of paramount importance for the system
to achieve its proper performance. Always use the right size and
quality of air duct with heat and sound insulation designed for
air conditioning. During the installation the air duct must be pro-
tected from any damage and as far as possible be placed with
the smallest branching and bends also built in tensely. Damaged
or congested air duct inhibits the ow leading to reduced sys-
tem performance. If the air duct is damaged during installation or
later use, it must be repaired or replaced. During installation - tak-
ing into account the possibilities - bends of 90 ° or more should
be avoided. (two 90 ° bends can reduce airow by 25%!)
INSTALLING THE AIR OUTLET
For better eciency place the unit’s air outlets as high as possi-
ble in the boat and also set the air vents slats up. By connecting
a branched prole it is also possible to connect more air out-
lets to the unit. When using the branching piece the air distri-
bution must be adjusted beforehand even before the pipes are
installed by using the air deector blade in the section. The unit’s
air duct system must not exceed a total of: ~ 10 meters, including
junctions and branching proles. Built-in pipes must be securely
fastened both on the unit and on the outlet.
WARNING!
The air outlet must not be directed towards the air
intake as short circulating cycles can lead to a loss
of performance!

MAGNETIC DRIVEN PUMP PLACEMENT:
The place of the centrifugal pump and the water strainer should
be chosen to be at least 30 cm below the waterline. The water
pump can be installed horizontally or vertically. The centrifugal
pump must be lled with water before rst use.!
If a self-priming pump is used, the circulation pump and the
water strainer can be placed above the waterline but due to
higher noise level preferably in a place where it does not dis-
turb the living space of the boat. (Engine – room, compartments
under seating surfaces, etc.)
WATER INLET AND OUTLET PROFILES:
WARNING!
Do not install the water outlet from the water inlet
within a distance of 150cm, because short circu-
lating cycles may lead to a decrease in the perfor-
mance of the device!
The water-inlet must be positioned as deep as possible on the bottom of
the boat. For better eciency it is important to make sure to have the cold-
est water possible in the condenser. Install the water outlet over the water-
line by maximum 150mm. The water drain should not be installed under-
neath the waterline as then the water circulation cannot be controlled.
WATER PIPES AND WATER STRAINER:
IMPORTANT WARNING:
Do not operate the system without a water strainer!
Operation of the system without a water strainer will cause
failure of the water pump and later the entire system failure.
Replace the plastic case water strainer every 2 years! The water system
must be able to be shut down during malfunction or maintenance so
without installing a ball valve the system is life-threatening!
For the water piping use a plastic water hose with high-grade steel spiral
reinforcement that is resistant to cross-sectional reduction during bending
and twisting.
INSTALLATION INSTRUCTIONS FOR THE BUILDING UP OF THE WA-
TER SYSTEM:
• Install the water intake tting as deeply as possible and as low and
close to the keel as possible. It is important to place the water-intake
tting so it can be easily accessible . When drilling the hull, ensure that
the drill is of the correct size.
• Seal the inlet with sealant suitable for boats and underwater use.
(Follow the instructions of the manufacturer of the sealant!)
• Attach a ball valve to the water inlet tting and install the bronze hose
end on the ball valve. The water system must be able to be shut down
therefore without installing a ball valve the system is life-threatening!
SAFETY WARNING!
• The water system must have a direct shut o
after the water inlet prole for the event of a
malfunction or maintenance. Without a shut-o
valve the system is life-threatening!
• Do not share the water supply and water ow of
the air conditioning system with other systems
(eg toilet, motor)!

PART 3. OPERATION - CONTROL
Before starting to operate the device check the entire system
as follows:
GENERAL CONTROL:
Check that there are no leaks in the water system.
• Check that the condensate can ow into the bilge; Fill water into the
drain pan and check for unhindered water ow to the bilge and water
basin. There should not be more than 2-3 cm of water left in the pan.
• Make sure that the air ducts their insulation are properly aligned.
• Make sure that the air duct is clean to avoid damaging of the device.
• Before starting the machine for the rst time check that the ball valves
on the water system are open.
• Make sure that the unit’s compressor does not emit any metallic or
vibrating sound when it is switched on. If so, adjust a few turns of the
nuts (3 pc) on the compressor’s base (3db), but do not tighten the
compressor to a tight, rigid position. It is important to maintain that the
compressor moves free on the rubber beds as these rubber bucks are
responsible for absorbing the vibration of the compressor.
ELECTRIC CONTROL:
• Check that the power source meets the rating instructions and the
power requirements of the device.
• Check that the current and control circuit are properly connected,
properly grounded, and that all connections are secure.
• Check that 230V / 50Hz power supply comes to the unit.
WARNING!
Each hose connection must be secured with 2 pieces of
stainless steel clamps each at 180 degrees!
• Place the water strainer so that it remains accessible during cleaning
following the ow direction on the water strainer.
• Connect the water pipe from the water inlet tting to the water
strainer, from the water strainer to the pump and then to the lower
condenser input - marked with an arrow - of the marine a/c unit.
• Connect the water pipe from the condenser outlet to the water outlet
tting.
• Seal the outlet with sealant suitable for boats and underwater use.
(Follow the instructions of the manufacturer of the sealant!)
• During the installation of the water piping all kinds of bends, loops and
use of 90 ° proles should be avoided.
• Use thread sealing cord for all metal threaded connections. (Loctite 55)
• Connect a ground wire to the metal parts that come in contact with
seawater including the seawater inlet and the air conditioner.
• When putting the boat in water check the sealing of the built-in ttings,
connectors and connections.
All metal parts that come into contact with seawater should be connected
to the boat’s grounding. These include:
• the water inlet access,
• the pump (ground wiring harness)
• the air conditioning.
Before starting the unit, check for possible leaks of the water system!
