AND MAINTENANCE GUIDE
WATER CASSETTES
Fig. 49
Fig. 50
TIPS FOR BEST USE
- Connect the cassette to a dedicated power socket protected by a
magnetothermal circuit breaker of suitable capacity for the electrical
input of the appliance.
-
When the water cassette starts or stops, especially in the heating
mode, creaking sounds may be heard. This is caused by thermal
expansion of the unit parts.
-
Mist may sometimes be produced by the cassette for a few seconds
in the cooling mode. This is quite normal and is caused by the
difference in temperature between the air flowing out of the appliance
and the air in the room.
-
Do not place heat sources near to the cassette as this could deform
the plastic parts.
-
Do not insert objects into the air intakes or outlets when the cassette
is in operation.
-
Do not place objects in a position that may obstruct the passage of
the air into the unit as this could affect appliance efficiency.
ENERGY SAVING
-
Do not open or close doors and windows too often. Constant
exchange of heat with the outside affects the working of the appliance.
-
Do not set too high a temperature (in the heating mode) or too low
(in the cooling mode).
-
Do not install the appliance where it is exposed to direct sunlight.
-
Use the
TIMER
for the timed switching on of the appliance, to avoid
the cassette operating needlessly while you are out of the house.
-
Use the
SLEEP
function during the night.
ROUTINE MAINTENANCE
!
ATTENTION!
Turn off the automatic circuit breaker before carrying out any
cleaning operations. Use a cloth dampened with lukewarm water
(max 40°C) and mild detergent to clean the cassette. Do not use
solvents or harsh detergents.
