must be installed as close to the HT 6Split / HT
12Split module as possible.
• Where necessary, install the vents.
• Safety valve with a nanometer at the central heat-
ing circuit and the safety valve at the hot water
system must be installed on relevant conductors
XL 11 and XL 4. In order to prevent air sockets,

Conden-
sate hose
Condensate elimination
The HT 6Split / HT 12Split module is equipped with a
condensate hose in the heat exchanger section. The
hose drains all condensate away from the device to
minimize the risk of damage. If necessary, the hose can
be extended.
Connecting refrigerant pipes
(not supplied)
Refrigerant pipes must be installed between the ex-
ternal module LSplit and HT 6Split / HT 12Split .
The installation must be executed according to the
applicable standards and directives.
CAUTION
the use of refrigerant pipes (dimension L) between the
outdoor unit and the indoor unit measured with a length
of L = 15m. The maximum permissible length of the re-
frigerant pipes can be 30m, but this requires topping up
the installation with a refrigerant.
Limitations
• Maximum pipe length, L6Split, L8Split, L12Split
is L=30 m.
