PART 2. INSTALLATION GUIDE 2.1 PURPOSE OF THIS MANUAL 2.3 CONCEPTUAL WARNING FOR ALL INSTALLERS: This manual provides guidance for the proper installation and operation of MBC Marine ESC series 230V self-contained direct expansion marine air conditioning systems. Its purpose is to offer installers and maintenance personnel detailed, step-by-step, clear, and practical support throughout the entire lifecycle of the system – from installation to troubleshooting and maintenance. No two boats or installations are the same. Do not copy the installation of another boat – the correct setup is determined...

2.4 SELECTING A SUITABLE INSTALLATION LOCATION Choosing the right placement for the system is critical. Before the installation consider the following guidelines: • A dry, well-ventilated enclosed space • Minimum 60 mm clearance from surrounding furniture (on all sides) • A stable, level surface, preferably with a slight 1-2 cm slope to allow condensate drainage • Easily accessible for maintenance • Isolated from heat sources and exhaust gases Avoid the Following Locations: • Engine room or machinery space • Directly next to ventilation ducts • Wet or damp floor areas • In the path of exhaust...

PLACEMENT OF THE AIR-CONDITIONING UNIT 3.3 TYPICAL INSTALLATION: See the picture below for the installation of a self-contained air conditioner unit. 1. Scoop Type Thru-Hull 12. Starting Booster Outlet

3.4 INSTALLING DISPLAY (CD-3 Type) Before installing the display, observe the following guidelines: Install the control panel only on a surface located higher than the centerline of the cabin, in a location protected from both external and internal sources of heat and light. Do not install the display in locations where it may be exposed to: • Direct sunlight • Nearby heat-producing appliances or devic • Partition walls with potential heat accumulation behind the panel • Directly above or below air intake or outlet vents • Ensure that the display is easily accessible for operation Although the...

PART 4. AIR SYSTEM INSTALLATION 4.1. RETURN AIR During operation, the air conditioning unit draws in room air through the return side, where it passes over the evaporator coil and is then discharged cooled (or heated) through the supply side. The volume and quality of the return air have a direct impact on the unit’s cooling/heating performance and safe operation. 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...

Supply air is the cooled or heated air that enters the cabin after passing through the evaporator. The total duct length should not exceed 4 meters. Avoid 90° or sharp bends, as they can reduce airflow by up to 25%. Supply grilles should always be installed as high as possible in the cabin, since cold air naturally sinks and warm air rises. When adjusting the direction of the grille louvers, make sure the air is not directed toward the return grille, as this can create a short air cycle. Ducts must be installed tightly and without creases, ensuring they are not compressed later by furniture or...

PART 5. SEA WATER SYSTEM 5.2. SEA WATER PUMP AND STRAINER The seawater cooling circuit is responsible for dissipating heat from the condenser of the ESC unit, making its proper operation essential. Any malfunction or insufficient water flow can lead to compressor overheating, the appearance of error codes (e.g., Error 6, Error 12), and even complete system shutdown. The circulating pump (magnetic driven pump) and the seawater strainer must always be installed below the waterline, at least 30–50 cm lower, to allow the system to be gravity-filled with water. This ensures air-free pump operation...
