Page 18: Installation
INSTALLATION Clean Air Act MarinAire MSBA series use environmentally friendly refrigerant R410A. Refer to www.epa.gov for rules & regulations on how to handle R410A. Operation Limits Cooling Operation: Incoming Water temperature (sea, river, lake water temperature) of 60 °F to 95 °F Heating Operation: Incoming Water temperature (sea, river, lake water temperature) of 40 °F to 77 °F... - Page 19 INSTALLATION Location of the system Typical spots are under the V-berth, in hanging lockers, under dinette seats, in cabinets or in outside dry lazarettes and the bottom of lockers. The equipment and peripheral components must fit in and/or be accessible in the selected location. The unit should be positioned on a firm, level, and horizontal (flat) surface and the condensate drain line should run in a downward slope from the unit to a suitable drain location.

Page 20: Air Distribution
AIR DISTRIBUTION Blower Assembly The ultimate engineering design allows the blower to be easily rotated 360° for an optimal angle, or removed for servicing. Simply loosen the metal clamp and rotate the blower outlet to the desired angle and tighten the metal clamp again. Do not leave the clamp loose and do not over-tighten it, as it may apply excess tension to the shroud and cause the plastic to crack. -
Page 21: Water Circulation
INSTALLATION WATER CIRCULATION Condensate Drain Connection During cooling or dehumidifying mode operations, the air conditioner may produce up to 1 gallon of condensate water per hour. It is important that condensate drains run downward in a continual slope, with no rises where the air can form a pneumatic lock. There must be a trap that will hold water if the vessel heels or rocks. -
Page 22: Electrical Power
INSTALLATION Electrical Power Both the air conditioner and pump require the same voltage. Make sure the power source is correct for the equipment. ( 110-120V/60Hz, 208-230V/50-60Hz and 220-240V/50Hz models available) Power is obtained from the master Circuit Breaker Panel in the boat. Power cables run from this panel to the air conditioner. -

If the setting temperature is lower than the room temperature, the unit will automatically switch to cooling mode. If the setting temperature is equal to room temp the unit will run on low fan speed.
- Page 26 OPERATION Remote Control Operation Cooling mode Display Use cooling function only when the sea water temperature is between 60F to 95F. Do not operate the unit under cooling mode when the sea water temperature is out of this range. Press the MODE button to select the cooling mode.
- Page 27 OPERATION Dehumidifying mode Display Please note that there is a humidity sensor installed in the system. Therefore desired humidity level can be set between 40% and 85%. Once the setting level is achieved the unit will stop. Fan will run every 10 minutes for 3 minutes to detect the LO LO current humidity level.

Page 34: General Troubleshooting
MALFUNCTIONS INSTRUCTION (MSBA Series) Humidity sensor error If your device displays E0, it means that the communication between the humidity sensor and the main circuit board is having problems. This may be because the humidity sensor cable on the circuit board is loose, or the cable between the sensor and the circuit board is broken. - Page 35 MALFUNCTIONS INSTRUCTION (MSBA Series) 4 Coil temperature sensor Error If your device displays E3, it means that the communication between the return evaporator temperature sensor and the main circuit board is having some problems. This may be because of the small socket on the circuit board is loose or the cable between the sensor and the circuit board is broken.
- Page 36 MALFUNCTIONS INSTRUCTION (MSBA Series) Low Pressure protection E5 means that the pressure levels are lower than normal. Please check the gauges. Once the compressor is not running, both the low and the high pressure gauges should show about 200 ~ 220...
- Page 37 MALFUNCTIONS INSTRUCTION (MSBA Series) Communication Error If your device displays EA, it means that the communication between wall control panel and the main circuit board is having some problems. This may be because of the phone jack on the circuit board or on the wall control panel is loose or unplugged or the cable is broken.
- Page 38 MALFUNCTIONS INSTRUCTION (MSBA Series) No Power to the wall controller If your control panel is not lighting up, then this may indicate a lack of power to your panel. Please make sure that you have power (110v or 220v depending on your model) between L and N terminals. If you have power and the panel still does not turn on, then check the fuse underneath a blue plastic cover on the circuit board, refer to the electrical panel diagram below.

Page 39: Maintenance
MAINTENANCE Reversing Valves Heat Pumps utilize a reversing valve; the valve must be energized periodically to keep the internal parts moving freely. To do this, switch the AC unit into heat for a few seconds, once a month. Seawater Strainer Clean the strainer periodically. -
