NOTICE
Risk of damage to property due to foreign bodies (e.g. shav -
ings, dirt), sealants and lubricants
Valves can be damaged and their function be impaired by foreign
bodies, greasing agents or oil.
f Do not use any greasing agents or oil for the installation.
f Flush any dirt particles or grease or oil residues out of the
pipework before installing the product.
f Consider the latest technical status (e.g. VDI 2035) when
choosing the operating fluid.
f Install a strainer in the supply pipe to avoid contaminated
operating fluids (VDI 2035).
6.1 Protection cap
The thermostatic valve is supplied with a plastic protection cap. It protects
the valve stem and can be used for setting of the flow rate during the con -
struction period.
f Turn the protection cap clockwise to close the valve.
f Turn the protection cap anticlockwise to open the valve.
NOTICE
Risk of damage to the valve
Do not use the protection cap for permanent shut-off of the
thermostatic valve against system pressure. The restoring force
of the valve stem may cause damage to the protection cap and
water may escape.
f
Protect the valve outlet with a metal cap.
6.2 Installation
1. If required, cut the pipe to the required length at a right angle to the
tubular axle.

pipes.
