• Run the fi lling pump until the pipe (8) is completely purged.
• Close the air bleed on the heat pump.
• Close the valve (7) and pressurize the glycol water circuit to
between 1.5 and 2 bar using the pressure gauge (6).
• Close the valve (5) and stop the fi lling pump.

The glycol water level may reduce during the fi rst
month after commissioning the installation. It can
also vary according to the temperature of the heat
source.
Any residues of glycol water must be stored in an appropriate
