Vaillant VPS R 100 1 M Notice D'installation Et De Maintenance page 75

Caution.
Risk of material damage caused by corro-
sion
Due to non-diffusion-tight plastic pipes in the
heating installation, air gets into the heating
water. Air in the heating water causes corro-
sion in the heat generator circuit and in the
product.
▶
If you use non-diffusion-tight plastic pipes
in the heating installation, ensure that no
air gets into the heat generator circuit.
1. Attach a drain cock at the lowest point in the installa-
tion.
2. Depending on your installation, connect the circuits in
accordance with the basic diagrams shown below.
Applicability: VPS R 200/1 B
▶
Connect a drain cock to the drain connection on the

▶
If you do not connect a drain cock, attach the drain

cylinder.
