Step 3: Evacuation
 Connect the vacuum pump on the maintenance valve (with
Schrader).
 Run the vacuum pump until the relevant vacuum is
reached. An absolute pressure of at least 0.2 mbar must be
achieved during evacuation. Pressures below 0.2 mbar are
advisable, however.
 Close the vacuum pump and start filling immediately.
Step 4: Filling
Once the leakage tightness test and evacuation have been car-
ried out correctly, open the maintenance valves on the indoor
unit. For refrigerant lines > 7.0 m, top up the refrigerant accord-
ingly.
The heat pump is now ready for use.
