8 - IMPORTANT NOTES
8.1 - INSTALLATION IN THE ENGINE COMPARTMENT (only for SPLIT models)
The air-conditioner use can cause the going off of sparks (switches, relays, etc...) To avoid the risk of explo-
sions, it is necessary to start the smoke-exhauster 10 minutes before switching on the air-conditioning system
and they must suck up the smoke as long as the air-conditioner runs.
8.2 - TROUBLESHOOTING
Only the qualified staff can execute the troubleshooting respecting the safety regulations.
8.3 - MULTIPLE INSTALLATION
It is necessary to space out the switching on delays of the air-conditioners at least of 5 seconds one from
another.
9 - MAINTENANCE
For an efficient functioning of the air-conditioner, follow these advices about checks and maintenance.
Intervention times can change according to the installation place, the pollution and the installation use.
"
Clean the sea water filter every week.
"
Clean the air filter every month.
"
Clean the condensation outlet pipe every four months.
"
Clean the condensation collection tray every year.
"
Clean the water intake every year (operation to be executed in shipyard).
"
Change the batteries (only for Vega MK II with remote control device) every year.
These operations must be executed only after having switched off the air-conditioner and only by the qualified
staff.
Don’t check the electrical circuit if none can bring help in case of accident.
"
Check hydraulic connections every year.
"
Consult also “Installation Manual”.
9.1 - CONDENSATION WATER AND ITS OUTLET
During the cooling cycle air-conditioners produce much condensation water, above all when it is damp. Check
periodically that there are no leaks or obstructions on the condensation outlet and that the condensation water
drains regularely. Pour in the condensation tray some water and check that it flows currently. If the condensa-
tion water drains to the bilge, it is better to let it flow towards a limited space and let it drain continually to avoid
stagnation that can cause unpleasant smells.
9.2 - AIR FILTER
The filter on the exchanger air outlet must be periodically cleaned and/or substituted. This filter avoids the
obstruction of the air-conditioner exchanger. The maintenance frequency depends on the running hours num-
ber and above all on the air pollution. We suggest to clean the filter every month. An obstructed air filter can
cause a decrease of the system efficiency in cooling mode (COOL). In the heating cycle (RC models) in sy-
stem with reversal cycle, it can block the system because of the high pressure; in EH models with electrical
resistance it can block the system because of the intervention of an internal safety device.
