4 ASSEMBLY AND INSTALLATION
4.1 INSTALLATION GUIDELINES
Above-ground fire hydrants TYPE 8003 may be installed on underground pipelines in case of horizontal
systems. The products described herein are designed for installation using flange on the pipeline acting as
medium (water) supply. The hydrant is equipped with special flanges to enable free above-ground part's rotation
(from 0
ο
to 360
ο
). Special bolts for connecting the lower part with the above-ground part, if they have been
loosened to enable rotation shall be tightened with max. torque 35Nm. Note that the system must not expose the
hydrant to bending or tensile stress from loading with the unsupported pipeline sections. A hydrant assembled
and adjusted by the manufacturer is ready for installation in the system. Any dismantling of the hydrant
components may result in loss of tightness.
