3. MAINTENANCE
For easy access to the outdoor unit to perform
small maintenance or to replace the batteries, it’s
recommended to install the outdoor unit at an accessible
spot. However, keep in mind to place it as open as pos-
sible in wind and rain.
3.1 Rain gauge:
You may unscrew the black rain collector tray by turning
it counter-clockwise for cleaning the interior of the rain
gauge. For this, please use a soft and long-haired brush.
Clean the black collector tray and remove any leaves.
Replace it onto the rain gauge (pay attention to the
3 protruding notches) and rotate the tray clockwise until
you hear a ‘click’ coming from the mechanism.
3.2 Outdoor temperature and humidity sensor:
Refer to the picture and detach the lower
4 weather vanes from the outdoor unit.
Blow into the holder containing the tem-
perature and humidity sensor and use a
soft brush with long hairs to clean the wind
guides. DO NOT USE WATER.
Replace and tighten the wind guides.
