The fan is not blowing or does not stop blowing.
An electrical part has failed.
Contact a qualified service technician.
The compressor cycled off because the mode was changed.
The compressor will cycle back on three minutes after the
mode change.
The mode icon is flashing.
The compressor cycled off because the target temperature
was exceeded by 1 °F (0.6 °C) or more.
The compressor will cycle on once the cabin temperature no
longer exceeds the set point.
The filter warning displays. The timer setting to clean or replace the air filter has been
reached.
1. Clean or replace the air filter.
2. On the Parameter menu, use the Filter Hours Reset func-
tion to reset the timer.
Fault: Return Air Sensor Failure An electrical connection or part has failed.
Contact a qualified service technician.
Fault: Suction Temp Sensor Failure An electrical connection or part has failed.
Contact a qualified service technician.
Fault: Discharge Pressure Transducer Failure An electrical part has failed.
Contact a qualified service technician.
The flow of seawater is obstructed or blocked.
1. Verify that the seacock is open and water if flowing to the
pump.
2. Clean the seawater strainer.
3. Check for a strong, steady flow from the overboard dis-
charge.
The seawater pump may be be airlocked.
1. Verify that the seawater plumbing is installed according
to the instructions in the installation manual included with
the air conditioner.
2. Remove the hose from the pump discharge to purge air
from the line, then place the hose again.
The seawater pump is not running.
1. Ensure the pump is not damaged from being run dry.
2. Verify that the pump is receiving voltage.
3. Check that water is flowing strongly out of the overflow.
The condensing coil is dirty.
Clean the condensing coil.
The seawater temperature is too high during heating opera-
tion.
Seawater temperature directly affects the unit's efficiency. For
the unit to heat (if the reverse-cycle option is available), the wa-
ter temperature must be less than 65 °F (18.33 °C).
Fault: High Discharge Pressure
There is insufficient return airflow.
1. Remove any obstructions in the return air stream.
2. Clean the air filter and the grille.
3. Check for crushed or restricted ducting.
The ducting must be as straight, smooth, and firmly sup-
ported as possible.
The return air pressure is too low during cooling operation.
The ambient temperature directly affects the unit's efficien-
cy. For optimum cooling, the air temperature must be 65 °F
(18.33 °C) or higher.
The return air is restricted.
1. Remove any obstructions in the return air stream.
2. Clean or replace the air filter and grille.
The seawater temperature is too low during heating opera-
tion.
Seawater temperature directly affects the unit's efficiency. For
the unit to heat (if the reverse-cycle option is available), the wa-
ter temperature must be 40 °F (4.44 °C) or higher.
Fault: Low Suction Pressure
The system has lost refrigerant
Contact a qualified service technician.
The supply voltage is too low.
1. Verify the voltage is correct at the power source.
2. If the problem persists, contact a qualified service techni-
cian.
Fault: Compressor Start Failure
An electrical part has failed.
Contact a qualified service technician.
Fault: Low Superheat A blower or expansion valve has malfunctioned.
Contact a qualified service technician.
Fault: Low Suction Temperature A blower or expansion valve has malfunctioned.
Contact a qualified service technician.
Fault: Clock Board Fault or Not Connected An electrical part has failed.
Contact a qualified service technician.
Fault: AC Low Voltage The supply voltage is too low.
1. Verify the voltage is correct at the power source.
2. If the problem persists, contact a qualified service techni-
cian.
