SeaMach Reverse Cycle <strong>Air</strong> Conditioners<br />
Dehumidification Screen<br />
Defrost Screen<br />
Defrost - Under certain conditions in the cooling mode, ice may form on the indoor coil. A dirty filter or<br />
restricted air flow can cause ice to form on the coil. To prevent excessive ice formation, the fan will<br />
continue to run, but the compressor will automatically turn off until the temperature of the coil rises to<br />
the factory set temperature. When this temperature is reached, the SeaMach unit will automatically<br />
resume normal operation.<br />
Alarms<br />
In addition to controlling the temperature, the Mach<strong>Air</strong> OLED controller also monitors the operation<br />
of the SeaMach unit and will display fault conditions. If a problem is detected, a message will be<br />
displayed on the screen. Once an alarm has been detected, it is necessary to turn power off to the<br />
SeaMach unit at the breaker and then restore power to the unit to clear the alarm.<br />
Low Voltage - The display will show Low Voltage if low voltage is detected for 10 seconds. For 115<br />
volt units, the low voltage threshold is 93 volts; for 230 volts the threshold is 185 volts. These limits are<br />
factory set and cannot be changed.<br />
Sensor INT - The display will show SENSOR INT when the built–in sensor in the Mach<strong>Air</strong> OLED<br />
display is defective. If this display persists, contact <strong>Marvair</strong> or your local SeaMach service center.<br />
Sensor OPT - The display will show SENSOR OPT (optional) when the remote sensor is defective or if<br />
the remote sensor was selected in the <strong>Air</strong> Sensor set up, but a remote sensor is not connected. If this<br />
display persists, contact <strong>Marvair</strong> or your local SeaMach service center.<br />
