Before installing the fittings, check the technical and commercial documentation, i.e. application for
media and operation parameters of the pipeline, in which they are to be installed.
Note! If the product is damaged mechanically, do not install it in the pipeline.
Any change in the operating conditions must be consulted with the hydrant's manufacturer beforehand.
The device is equipped with a draining device to protect the device's column against defrosting. This protection
operates automatically provided that the drain hole has not been clogged during installation and operation of the
product and that a drainage was provided around the hole with applicable capacity, made of gravel or other
permeable material, see diagram. To ensure better water outlet from the drain, place a plastic hose on the outlet
pipe to distribute water in the gravel bed.
