9.2 Failsafe and Fault Handling Codes
When a fault is detected the Marine Climate System will display one of the
following Mnemonic fault codes:
 "ASF": Indicates Air Sensor Fault.
 "FIL": Indicates filter needs replacing (if this option is enabled).
 "HPF": Indicates High Freon Pressure.
 "LAC": Indicates Low AC voltage (if this option is enabled).
 "LPF": Indicates Low Freon Pressure (Not applicable to MCS models).
 "PLF": Indicates high water temperature in condensing coil (if this option
is enabled).
NOTE
I
"HPF" is not indicated and does not cause lockout in Heat Mode.
"LPF" has a 10 min shut down delay.
Failsafe Level 0
Only "ASF" detected and displayed.
The Marine Climate System will shut down and will not restart until the fault
is repaired.
Once the fault is repaired the Marine Climate System will restart.

Possible Reason
Seawater temperature too high
for cooling or to low for heating.
Improper air sensor location.
Cold supply air returning directly
to return air grille.
MCS6, MCS12, MCS16
Solution
Seawater temperature will
directly affect the air conditioning
unit's efficiency.
This air conditioning unit can
effectively cool your boat in water
temperatures as low as 40 °F
(4.4 °C) and heat (if reverse cycle
option is installed) in water up to
90 °F (32.2 °C).
See corresponding section in
"Control Panel Troubleshooting"
on page 27.
Redirect supply air so that it is not
directed into the return air
stream.
