The average length of the refrigerant connection between the devices is 7.5 m.
The external device is
factory filled for connections of up to 15 m.
For longer connections, it is necessary to supplement
the refrigerant according to the table below.

Example 1:
When installing the external device and accompanying internal device with the distance of
30 m, it is necessary to supplement the system with additional refrigerant. The quantity of the refrigerant
is calculate with the following equation:
(30 m – 15 m) x 30 g/m =
450 g
In the given example, it is necessary to supplement the system with
450
g
of refrigerant
R410 A.

Example 2:
When installing the external device and accompanying internal device with the distance of
30 m, it is necessary to supplement the system with additional refrigerant. The quantity of the refrigerant
is calculate with the following equation:
(30 m – 15 m) x 60 g/m =
900 g
In the given example, it is necessary to supplement the system with
900 g
of refrigerant
R410 A.
NOTE
In case of installing an internal device which is higher than the external device and when
the height difference is 4 m or more, a qualified person has to manufacture oil siphons for
every 4 m of height difference to enable adequate oil transport.
In case the external device is higher than the internal device, oil filters are not necessary.
WARNING
The device contains the refrigerant HFC which is classified as a greenhouse gas according
to the Kyoto protocol. This is why operating the device is only allowed to persons authorised
for working with the refrigerant as defined by the national legislation in force. While
performing works on the device it is necessary to prevent the refrigerant to leak into the
atmosphere.
