standard filling
15 mThe refrigerant pipes' total length with
additional filling1
11. Additional filling of refrigerant can be done when the unit runs in cooling
operation:
For refrigerant pipe 1/4" - 3/8" = 15 g/m
For refrigerant pipe 1/4" - 1/2" = 20 g/m
For information about pipe dimensions, see section
"Technical Specifications" on page 16.
Condensation drain
For condensation removal, the AG-CH10 accessory of

Pump down
Pump down means retrieving all refrigerant in the
outdoor unit without losing the system's filling. This is
done when the climate unit is to be moved or during
repair of the cooling circuit.
Procedure for "Pump down":
1. Connect a manometer assembly to the low pres-
sure valve, open partially (1/4 turns). Extract air
from the manometer. Then close the high pressure
valve fully.
2. Start the climate unit in cooling mode. When the
pressure that is read out from the manometer has
dropped to a value less than 0.6 bar (absolute
pressure), the low pressure valve must be closed
fully and the climate unit switched off.
