Docking the indoor unit
Docking the climate system
The refrigerant pipes must be installed between the L
Split outdoor unit and the HM 6Split / HM 12Split indoor
unit. Installation must be carried out in accordance with
the current standards and directives.
Limitations
• Maximum pipe length on either side, L 6Split, L
8Split, L 12Split, (L): 30 m.
• Maximum height difference (H): ±7 m.
Removing condensate
Connecting the refrigerant pipe
(not included)
NOTE
It is absolutely necessary for the appropriate safety
valve to be fitted directly on the cold water supply pipe
to the HW tank, to protect the tank against an exces-
sive pressure increase.
NOTE
The outdoor unit, filled with refrigerant at the factory, al-
lows for the use of refrigerant pipes (size L) between the
outdoor unit and the indoor unit measured with a pipe
length of L = 15m. The maximum permissible length of
the refrigerant pipes can be 30m, however this requires
topping up the system with refrigerant.

• The connection of the outdoor unit to the indoor
unit must ensure the free flow of the rerigerant.
To properly top up the refrigerant, see the section “Filling
the system with refrigerant”.
The pipe connections of the climate system are made
from the top of the appliance except safety assembly.
• All required safety devices and shut-off valves
must be fitted as close to the HM 6Split / HM
12Split unit as possible.
• Vent valves must be installed where necessary.
• The safety valve with the pressure gauge and air
vent on the central heating circuit, must be fitted
to the appropriate connection XL 11. To prevent
air pockets from forming, the overflow pipe must
be inclined in its entire length from the safety
valve and must also be frost proof.
• When connecting to a system (where all radia-
tors / underfloor heating circuits are equipped
with thermostatic valves or solenoid valves), ap-
propriate hydraulic solutions (e.g. excess-relief
valve, low loss header, buffer in parallel or open
heating loops). Remember to always keep the
minimum required flow and volume of the sys-
tem - see the sections “Minimum system flow”
and “Buffer vessel”.
The HM 6Split / HM 12Split is equipped with conden-
sate hose draining it off the drip tray placed in the
lower part of HM 6Split / HM 12Split. Hose should
be connected to the WM1 stud. This enables draining
off all condensate away from the device, minimising
the risk of damage. The hose can be extended or re-
placed, if needed.
