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.

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.
