Quality of heating water

Use the correct fill water that is suitable for the components
of your heating system. We recommend fill water prepared
according to Guideline VDI 2035-2.
A high pH value and low electrical conductivity in the fill
water will reduce to a minimum the risk of corrosion to iron
and copper materials, as long as there is also a low oxygen
content. This will also minimise scaling (calcification).
Fill water characteristics
pH value at 25°C
Electrical conductivity at 25°C
Oxygen content
Chloride
Water hardness
Material damage
Unsuitable fill water can damage your system due
to scaling and corrosion.
»
If necessary, ensure that the fill water is pro-
fessionally softened and desalinated.
9.3.3

Heating system safety valve drain

Note
The indoor unit has an internal safety valve (DHW,
heating).
»
Observe national and regional regulations re-
garding the design of the drain and prescribed
regular operational tests.
If the valve is activated, the water is drained off via a hose
on the rear of the indoor unit.
»
Size the safety valve drain so that the water can drain
freely via an open and readily visible waste water
drain.
»
Install the hose with a consistent fall to the drain.
Avoid kinking the hose.
»
Secure the drain hose to prevent movement when
water is running out.
WARNING: Burns
The water that escapes when it is triggered is hot
and can cause scalding on contact with skin.
»
Implement the safety valve drain in such a
manner that there can be no contact with the
water escaping from the machine.

Filling the heating system

Note
To protect the potable water supply, a heating sys-
tem with an AIR FALCON C11B T201 must be filled
in accordance with the UK Water Supply (Water
Fittings) Regulations 1999, Section 8 G24.
»
Fill the heating system with suitable fill water using
the drain and fill valve.

»
Vent the pipework.
Note
For easier filling, the 3-way switching module is
set to a position suitable for filling at the factory.
The cable from the 3-way switching module to the
controller has been disconnected at the factory.
»
After filling, plug the connector into the 3-way
switching module.
