How It Works
Your self-contained air conditioner consists of four main components and a refrigerant gas circulating through the
system. The BLOWER draws warm cabin air across the fins on the EVAPORATOR where the heat from the air is
transferred to the refrigerant in the evaporator coil. As the refrigerant evaporates from a liquid into a gas, it absorbs
the heat from the cabin air. The COMPRESSOR then compresses the refrigerant gas and pumps it through the
outer tube in the CONDENSER COIL. The seawater pump circulates cool seawater through the inner tube in the
condenser coil; this cools the refrigerant and condenses it into a liquid. The heat from the refrigerant is exchanged
to the seawater and discharged overboard. The liquid refrigerant is then passed through the EVAPORATOR COIL
and the cycle repeats; removing heat from the cabin air lowering its temperature. The cooled air is blown through
the ducting and out the supply air grille(s). For reverse cycle heating, the refrigerant flows in the opposite direction
through the reversing valve. Heat is transferred from the seawater in the condenser coil to the refrigerant and then
to the air blowing through the evaporator into the cabin. Seawater temperature will directly affect the a/c unit's
efficiency. This a/c unit can effectively cool your boat in water temperatures up to 90°F and heat in water
temperatures as low as 40°F.
OPERATION
DO NOT turn the unit off and immediately back on. Wait at least 30 seconds for
refrigerant pressures to stabilize.
WALL MOUNT CONTROL OPERATION
•Don't install the wired display in a location where it can get wet.
•Don’t knock, throw or open the display frequently.

9. Mode Button
The display control has a memory function. When the power supply is off, the wired display control will keep the
last modes and setting, including MODE, TEMP, and FAN speed. When the system is turned back on, the previous
settings will still remain default.

Power ON/OFF •Press ON/OFF button to turn the unit on. Press it again to turn the unit off.
FAN Control
•Press the FAN button, the fan speed will change in the following order:
→ HIGH →MID → LOW → AUTO →
•In “DEHUMIDIFY” mode, the fan will work at low speed automatically
Temperature Setting
Press the ▲ or ▼ temperature setting keys to increase or decrease in 1o increments
•The setting range of temperature in each mode:
COOL 61°F 86°F or 16°C 30°C
DEHUMIDIFY 61°F 86°F or 16°C 30°C
HEAT 61°F 86°F or 16°C 30°C
FAN In this mode, temperature cannot be changed.
AUTO In this mode, temperature cannot be changed.
MODE Setting
•Press this key to change the operation mode in order of
→ COOL → DEHUMIDIFY → FAN → HEAT → AUTO →
•In “COOL” mode, the LED marked will be illuminated if the set temperature is lower
than room temperature. If set temperature is higher than room temperature, only the
fan will run.
•In “Dehumidify” mode, the LED marked will be illuminated and fan will work at low
speed within a certain temperature range. Dehumidifying is more efficient than in
cooling mode and it will save energy.
•In “FAN” mode, the room temperature will be displayed and the temperature cannot be
set.
•In “HEAT” mode, the LED marked will be illuminated when the set temperature is
higher than the room temperature. When the setting temperature is lower than the
room temperature, the will not run.
•In “AUTO” mode, the LED marked Auto will be illuminated and the room temperature
will be displayed. The temperature cannot be set as the system will run automatically
in the appropriate mode according to the contrast between room temperature and set
temperature.
•
COOL ONLY UNITS HAVE NO HEAT MODE.
Display Fahrenheit or
Centigrade Pressing the ▲ and ▼ key simultaneously, will switch between Fahrenheit Centigrade
modes.
Error Codes •Refer to the provided installation manual.
Key lock
•Press ▲and FAN key simultaneously, all keys are locked. Press ▲and FAN key
simultaneously again, to unlock the keys.
•When keys are locked, the controller is locked out of system operation. “EE” will be
displayed.

MODE DESCRIPTIONS
COOL Mode Description
●According to the difference between room temperature and set temperature, the microcomputer will decide
if cooling mode is on or off.
●If room temperature is higher than set temperature, unit runs in cooling mode.
●If room temperature is lower than set temperature, the compressor stops and only the fan will run.
●Set temperature should be in range of 61°F to 86°F or 16°C to 30°C
HEAT Mode Description
●If room temperature is lower than set temperature, the compressor runs in HEAT mode
●If room temperature is higher than set temperature, the compressor will shut off and the fan will run.
●Set temperature should be in range of 61°F to 86°F or 16°C to 30°C.
●COOL ONLY UNITS HAVE NO HEAT MODE.
DEHUMIDIFY Mode Description
●In DEHUMIDIFY mode, if the indoor temperature is higher than temperature setting, the unit will
operate in cooling mode and the fan will run on low speed
●Set temperature should be in range of 61°F 86°F or 16°C to 30°C
FAN Mode Operation Procedure
●Temperature can not be set in this operation mode.
