If the product is damaged, return the product to the place of purchase. Before the installation please check all parts are in the box and not injured: - A/C unit - Display - 5m LAN cable - Temperature sensor - 4...

A SAFETY INFORMATION: The manufacturer assumes no liability for damage to the device in the following cases: • Installation or connection failure • Damage to the product due to mechanical impact and over voltage • Modification of the product without the express written permission of the manufacturer • Unusual use, differing from standards FIRE PROTECTION WARNING: Installation and maintenance of the unit may be dangerous due to pressurized copper pipes and electrical equipment. When working on the unit, always take the safety precautions into account and wear protective goggles during...

Before starting the installation it is important to plan the location of all the components of the system in advance, including: • marine a/c units and electric box, • air ducts and water pipes, • location of the sea water pump, • the drainage of drop water and its removal from the boat, • sea water intakes/outlets, • electrical connections, • and the display location. ©WARNING! Start the installation only if the location of each unit complies with the relevant regulations. At planning, make sure that there is enough space for subsequent installation and maintenance work.

INSTALLATION GUIDE SAFETY WARNING! IDo not install the air conditioner in the bilge or engine compartment 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 possible 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...

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 specifications! 3.0” [76mm] Minimum dearance in front of condenser or /evapolator coils. TOP VIEW OF 2 TYPICAL INSTALLATIONS 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...

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 airflow through the air pipes. The air outlet direction of the unit’s fan can be adjusted horizontally or vertically. Adjust the air outlet position by loosening the fixing screw and tightly fasten the fixing 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 distance on the edge of the drop...

Unimpeded air flow 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 protected from any damage and as far as possible be placed with the smallest branching and bends also built in tensely. For better efficiency place the unit’s air outlets as high as possible in the boat and also set the air vents slats up. By connecting a branched profile it is also possible to connect more air outlets to the unit. When using...

THE WATER SYSTEM OF THE UNIT SAFETY NOTICE! If you do not have sufficient training to install the water system of the unit consult a qualified boat technician.. In saltwater environment - in case of longer stops - it is recommended to remove seawater from the system. Frost protection should be applied during fresh water use below -5C! IMPORTANT WARNING! Sea water pump power consumption cannot exceed nominal 3A Please use less than 3A consumption sea water pump, or install a switch relay. WARNING! Do not use the system if the sea water below 7 celsius!

THE WATER SYSTEM OF THE UNIT Follow the guidelines below to properly install the water system of the marine air conditioner unit.See pictures below: PUMP HEAD ORIENTATION HOSES MUST NOT HAVE KNIKS, LOOPS OR HIGH SPOTS WHERE AIR CAN BE TRAPPED STEADY UPWARD FLOW FROM INLET TO UNIT THEN DOWNWARD TO OUTLET.

SEA WATER 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 filled with water before first 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 disturb the living space of the boat. (Engine – room, compartments under seating surfaces, etc.) The water-inlet must be positioned as deep as...
