INFORMATION
Also read the precautions and requirements in the "2 General safety
precautions"[410].
NOTICE
In case of plastic pipes, make sure they are fully oxygen diffusion tight according to
DIN4726. The diffusion of oxygen into the piping can lead to excessive corrosion.
▪ Connecting piping – Legislation. Make all piping connections in accordance with
the applicable legislation and the instructions in the "Installation" chapter,
respecting the water inlet and outlet.
▪ Connecting piping – Force. Do NOT use excessive force when connecting the
piping. Deformation of the piping can cause malfunctioning of the unit.
▪ Connecting piping – Tools. Only use appropriate tooling to handle brass, which is
a soft material. If NOT, pipes will get damaged.
▪ Connecting piping – Air, moisture, dust. If air, moisture or dust gets into the
circuit, problems may occur. To prevent this:
- ONLY use clean pipes.
- Hold the pipe end downwards when removing burrs.
- Cover the pipe end when inserting it through a wall, to prevent dust and/or
particles from entering the pipe.
- Use a decent thread sealant to seal connections.
- When using non-brass metallic piping, make sure to insulate both materials
from each other to prevent galvanic corrosion.
- Because brass is a soft material, use appropriate tooling for connecting the
water circuit. Inappropriate tooling will cause damage to the pipes.
▪ Insulation. Insulate up to the base of the heat exchanger.
