10 Inspection and Main-
tenance
WARNING
Evaporator fins can be damaged.
The evaporator fins can be easily bent. When install-
ing, make sure that bent fins are correctly aligned
again to ensure proper air feed.
It is recommended that a number of routine checks be carried out
at regular intervals and when switching on the air-conditioning
system so that the system continues to function properly and
maintains its performance level for many years.
At least once per month:
Check the operation of the air conditioning system.
Switch on the self-contained air-conditioning unit
The self-contained air-conditioning unit must run for at least 10
minutes.
10.1 Air filter
At least once per year:
Check the air filter on the evaporator of the air conditioning unit
and clean if necessary:
Pull the air filter upward out of the guide rails.
Clean the air filter with a vacuum cleaner and use water to flush
it if necessary.
Reinsert the air filter into the self-contained air-conditioning
unit.
10.2 Sea water circuit
The operation of the sea water circuit must always be checked,
especially after a longer absence.
Every time it is switched on, immediately
Check whether sea water flows out of the sea water outlet.
At least once per week
Check the sea water strainer for cleanliness.
Clean if necessary.
At least once per month
Check the entire sea water circuit from the through-hull fitting
to the sea water outlet for leaks.
At least once per month
Check the condensate outflow from the condensed-water tray
for free passage and leaks.
Check the condensed-water drain line for free passage and
leaks.
Once per year
Note
The sea water circuit is only to be cleaned by an ex-
pert (installer or Webasto Service Centre).
Clean the sea water circuit, including the condenser of the
self-contained air-conditioning unit.
The time interval depends on the degree of biological fouling (by
shellfish etc.).
Soiling of the sea water circuit reduces the sea water flow rate,
which decreases the heat dissipation and can result in high-pres-
sure switch-offs.
If the condenser is soiled, the cooling or heating capacity of the
system decreases.
10.3 Electrical wiring
At least once a year, the electrical connections must be checked
for corrosion of the contacts and firm seating. Also check the me-
chanical strain relief of the lines.
