7.4.3 Evacuation
1) Connect the end of the filling hose mentioned above to the
vacuum pump to pump the pipework and indoor unit
empty. The levers "Lo" and "Hi" on the multi-way valve
must be open. Start the vacuum pump. The duration of the
pumping empty process varies with different lengths of
the pipework and the pump output. The following table
shows the time required for pumping empty.
Time required for suction with a vacuum pump 0.11 m/hour.
Length of the pipework
less than 10 m
30 min. or longer
0.6 mbar or less
2) Close the levers "Lo" and "Hi" on the multi-way valve at the
desired vacuum pressure and switch off the vacuum
pump.
Finally
1) Open the valve handle on the liquid side completely in an
anti-clockwise direction with a maintenance valve key.
2) Open the handle of the valve on the gas side completely in
an anti-clockwise direction.
3) Loosen the filling hose connected to the air side slightly
from the maintenance connection to reduce the pressure,
then remove the hose.
4) Tighten the screw nuts and caps on the air side mainte-
nance connection again with an adjustment key. This pro-
cess is very important to prevent leaks on the system.
5) Position the valve caps on the air and liquid side mainte-
nance valves again and tighten. The purging with the vac-
uum pump is complete. The split heat pump is now ready
for test operation.

Commissioning

8.1 General

To ensure that commissioning is performed correctly, it should
only be carried out by an after-sales service technician author-
ised by the manufacturer. This may be a condition for an addi-
tional warranty (see "Warranty service").

8.2 Preparation

The following items must be checked prior to commissioning:
All of the indoor unit connections must be installed as de-

scribed in Cap. 6.1 on page 13.
 All of the outdoor unit connections must be installed as de-
scribed in Cap. 7 on page 17.
All valves which could impair the proper flow of the heating

water in the heating circuit must be open.
The air intake and air outlet paths must be clear.

The settings of the heat pump manager must be adapted

to the heating system in accordance with the manager's
operating instructions.
The heating water circuit, domestic hot water cylinder and

buffer tank of the indoor unit must be completely filled and
purged.
Ensure that the condensate drain functions properly.

 The outflow from the heating water pressure relief valve
must also function correctly.
Purging the heating system:

Ensure that all heating circuits are open, purge the system
at the highest position and refill water if necessary (comply
with static minimum pressure).
The hydraulic network must be flushed correctly before in-

stalling the heat pump. This includes the supply line to the
heat pump. Only when flushing is complete can the heat
pump be hydraulically integrated.
 The dirt traps present as standard or included for assembly
must be inspected between 4 and 8 weeks after the heat
pump is commissioned or changes made to the heating
system and cleaned if necessary. Further maintenance in-
tervals must be scheduled depending on the level of soil-
ing, which must be defined and carried out by a suitably
qualified person.
