2 .5 Installation of the external unit
The maximum length of the connection lines to the internal unit
must be 50 m in each sense (for lengths greater than 30 m it will
be necessary to top up the R410A load with 40 g for each metre).
Furthermore, the maximum difference in height between the in-
ternal and external unit must not exceed the figures indicated in
the “Connection” table .
The installation site must be chosen with extreme care in order
to ensure adequate protection of the device against impact or
possible consequential damage.
2 .5 .1 Cautions
Mount the external unit in a position which is capable of sup-
porting the weight.
Choose a place that is adequately ventilated and in which the
external temperature in cooling does not exceed 40°C.
Leave sufficient clearance around the device in order to avoid
recycling and to facilitate maintenance operations.
Prearrange a layer of gravel for the drainage of the defrosting
water underneath the device.
When installed in a location with high snow fall, mount the
support of the device at a height which is greater than the
maximum level of snow.
Use concrete or a similar material to make the base, and en-
sure good drainage. In this case, prearrange vibration damp-
ing blocks in order to prevent the transmission of the vibra-
tions.
Ordinarily, ensure a base height of 5 cm or more.
We recommend always using a condensate collection tray
and drain pipe, or in regions with cold winters, ensure a
height of at least 15 cm from the feet on both sides of the
unit.
(In this case, leave clearance below the unit for the drain pipe,
and to prevent freezing of drainage water in cold weather).
