4 - STORAGE
The Hydrants should be stored in a location that protects them
from any pollution or contamination. Do not store the hydrants
out of doors. During the storage period, the hydrants must be
protected (e.g. by covering them with a tarpaulin) against outside
influences and impurities like:
- Humidity and rain, to avoid corrosion,
- Wind and sand, to avoid the penetration of solid particles that
could damage the guiding area and seat,
- Sunshine and heat, to prevent oxidation of the elastomer and
coating due by ultraviolet light.
Take into account also that long storage under severe conditions
can cause damage to the coating, elastomer and seals.
Leave the shut-off cone in the closed position in order to avoid to
damage it.
Take care to not damage the coating. Ensure that the hydrants
is stored in a stable position. Store hydrants lying in a stable
horizontal position.
If long-time storage is required, the place of storage should be
selected in such a way that the following conditions are met:
frost-protected - cool - dry - dust-free - dark (for elastomer
UV-light is inadmissible). If it is impossible to comply with these
conditions, the hydrants must be packed to meet the above
mentioned requirements (e.g. they must be sealed inside dark
plastic sheets).
The protective flange covers or packing should be kept up to the
assembly phase.
The valves are designed for a storage temperature of – 20°C to
+50°C.
5 - INSTALLATION
INTO THE PIPELINE
WARNING
Before
technical leaflet W331 from DVGW
for deployment, installation and
implementation.
5.1 Location of installation
Warning! After installation, it is important that all around the
hydrant there is free access for operation and maintenance.
installation,

to
The technical data and performance may be modified
without prior notice depending on the technical advances.
5.2 Assembly positions
Our hydrants are designed to be installed and assembled only in
the vertical position.
5.3 Installation
Prior to installation:
• Remove all packing material from the hydrant, as well as
the protective flange covers.
• Check configuration of the material in order to control the
compatibility of the hydrant with the fluid that is going to
flow inside and with the external environment.
• By turning the operating square cap anti-clockwise, and
clockwise open and close the hydrant to check its integrity
and ensure that it works properly. If it does not, or if any
damage is observed, inform us immediately.
• Clean off any dirt which may have settled on the sealing
surface during transport or storage. Check if there are
foreign bodies that could prevent correct operation.
• Check that pipeline is free from impurities and foreign
matter. If necessary flush and clean the pipeline in order to
evacuate all foreign matter. Foreign matter, residue or dirt
might damage the shut-off cone or affect the operation of
the hydrant and even block it.
• Check that the gaskets' seats on the duck foot bend (N-piece)
and that the gasket of the hydrant flange are perfectly clean
and free from stripes, which may prevent watertight sealing.
If necessary, clean the flange of the duck foot bend (N-piece)
to remove any particles or dirt which may have been deposited
there.
• Check that the flanges of the duck foot bend (N-piece) are
drilled in accordance with the same standards as the hydrants.
• The mating flange of the duck foot bend (N-piece) must be in
the horizontal plan position.
When connecting the hydrant to the pipe, avoid the transmission
of stress from the pipe to the hydrant body. Make sure that the
distance between the top of the operating square cap and the
Ground level is between 90 to 220 mm (as requested in technical
leaflet W331 from DVGW / see figure 5).
As the hydrant is delivered with a built-in inlet flange gasket
(which is reinforced by a composite insert) , do not :
• Use an extra flange gasket to connect the hydrant to the
network.
• Remove the built in inlet flange gasket to replace it by a
standard flange gasket.
It is required to install an isolation valve on the pipe, upstream of
the inlet of the hydrant, in order to isolate it from the network for
maintenance work.
For stability, the duck foot bend (N-piece) must be sufficiently
anchored by means of a concrete block or by any other appropriate
means.
For assembly, 8 bolts with size of M16 are necessary. For each
flange's hole, washers shall be placed on both sides of the
flange's assembly:
