This applies also to installation and setting of safety devices and
hydrant, as well as welding at supporting parts.
1.2.4 Dangers when handling the hydrant
Our hydrants are designed to the state of the art and according
to the approved safety rules. However, these hydrants can
constitute a danger for persons and property especially when
handled by untrained staff in an unskilled manner or when
they are not used in accordance with their proper purpose. This
may cause danger to life and limb of the user or third parties or
damage to the hydrants and other property.
Access to the danger zone shall only be possible when the hydrant
is out of operation and when it is ensured that the conveying units
and the following units are shut down, in order to avoid danger to
the operating and maintenance staff.
Whoever, in the user’s facilities, is engaged in mounting,
dismantling or remounting, operation and service (inspection,
maintenance, repair) of the hydrants, must familiarise
themselves with the applicable regulations in force locally.
Work at the hydrant site (as e.g. control, maintenance and repair
work) shall only be carried out when the area has been secured
and shut down and when power at the area has been switched
off.
Before removing safety devices and/or carrying out work on the
hydrants, the pipe section must be made pressureless to avoid
risk. Unauthorized, erroneous or unexpected operation, as well
as dangerous movements caused by stored energy (compressed
air, pressurized water, hydraulic system), must be avoided.
A copy of the operating and maintenance instructions must
always be available on site and must be protected against oil and
grease.
If necessary, or as specified by the rules, use suitable personal
protective equipment!
Any instructions concerning safety and dangers at the working
area must be observed and a written copy must be maintained
in legible condition and periodically renewed or replaced, if
necessary.
During operation, protective gloves must be worn.
In the event of changes to the hydrant or its operating
performance which might affect safety aspects, operation must
be stopped immediately and the problem reported to the relevant
department/person!
Before any maintenance operation on the hydrant, the network
section where the hydrant is installed must be isolated upstream,
and depressurized in order to relieve the hydrant free from
pressure. Failure to comply with this recommendation will lead
to a situation of danger to persons and property.
When maintenance and repair work at the hydrant has been
finished prior to commissioning of the hydrant, check whether all
safety devices and equipment have been remounted and make
sure that they are operative.
If work is carried out in the vicinity of the hydrant that may lead to
soiling (e.g. concrete work, masonry, painting, sandblasting) the
hydrant must be covered effectively.

Each product is individually tested on the production line before delivery. The strength and tightness of the gate valves are tested in the
manufacturing factory according to DIN EN12266, DIN EN14339 and DIN EN1074-6.
HALIOSTM and HALIOSTM Premium DIN Underground Fire Hydrants are only suitable for “OPEN – CLOSED” duty. Their main purpose is
the access and withdrawal of water in order to extinguish fires.
They comply with European standards DIN EN14339, DIN EN1074-6 and the relevant DVGW requirements W 386 (P), and they have
DVGW approval for drinking water as well as the CE mark according to European Construction Products Directive 89/106/CEE.
These hydrants are designed with a one-piece body. The stem bearing is trapped in the flange bearing without contact with the medium.
A safety interlock prevents ejection of the inner trim during dismantling work for maintenance. The cams at the outlet-claw prevent the
ejection of the standpipe under vibration conditions. The automatic drainaged device, placed on both sides, limits the amount of residual
water to a value below the requirement of the DIN standard.
They are proposed in Single Shut Off version (UHA) or Double Shut Off version (UHAD), and are available in STANDARD or PREMIUM
level of finish.

2.2 Functional description and allowable operation
The sintgle shut-off underground fire hydrant is composed of:
• A vertical tubing (7) having in the lower part a horizontal
inlet flange (1) to connect to the water network, and in the
upper part an outlet claw 75 (R. 11).
• A shut-off valve made with of a cone (4) encapsulated in
elastomer, and closing on the coated seat (2) at the bottom
part of the body. This cone (4) is linked to the operating
stem (9) in the upper part by a tube (6) having a nut (8). The
operating system is operated through a square cap (10) .
• A double automatic drainage device located on both side
of the bottom part, above the seating area of the cone (3).
The rotary motion, in the anti-clockwise direction, on the
square cap (10), in the upper part of the hydrant, moves the
shut-off cone (4) in a downward direction in order to release
the passage around the seat. Upon opening, the water passes
around the shut-off cone in the cone chamber (5) and rises
through the vertical tubing (7) to emerge at the outlet claw
(11). During the downward movement of the shut-off cone (4),
its two guiding lugs close the two drainage orifices (3).
The rotary motion in the clockwise direction on the square
cap (10) , in the upper part of the hydrant, moves the shut-off
cone (4) in an upward direction in order to close the passage.
Upon closing, the flow stops. At the end of the upward
movement of the shut-off cone (4), its two guiding lugs open
the two drainage orifices (2) in order to empty the hydrant.
In the case of the double shut-off underground fire hydrant,
there is a floating ball (12) located in the cone chamber (5).
This floating ball follows the movement of the shut-off cone,
and allows secure closing.
Closing/Opening direction are indicated on the products.
Operation of our fire underground hydrants must be
performed with the appropriate operating Key «C» according
to DIN 3223, for square cap 32. The appropriate operating
Key «C» should only be used for the recommended torque
values according to Table 4, otherwise the hydrant might be
damaged.

2.4 Intended use
HALIOSTM and HALIOSTM Premium are for "OPEN - CLOSED"
operation only.
By virtue of its design, and its different material options, they
might be used for potable water or raw water.
Before installation, check the configuration of the material in
order to control the compatibility of the hydrant with the fluid
that is going to flow both inside and in the external environment.
If used with technically clean fluids (e.g. drinking water,
depending on allowable operating pressure) flow speeds up to 4
m/s are allowed in permanent conditions of use (see table 2 for
limits), when the wedge is in fully opened position.
In case of fire protection use, maximum flow rate should not
exceed 1.5 times the Kv-value for cavitation safety reason.
Temperature of the medium shall not exceed max. 50°C (see
table 3 for limits).
European Standard DIN EN1074-6
Maximum Temperature 50°C
Maximum Flow Velocity in
permanent conditions of use 4 m/s (PFA16)
Table 2: Maximum temperature and flow velocity
Installation conditions can be outdoors, buried in the ground, in
a valves‘ room.
All deviating operating instructions and deviating fields of
application are subject to the manufacturer’s approval.
As we do not have any control or prior knowledge of the quality
and properties of the water, we recommend the installation of
our hydrant with enamel coating when the water tends to form
deposits or encrustations.
2.5 Unacceptable operation
Do not use the shut-off cone of the hydrant in an intermediate
position to restrict water flow. Continuous operation in a flow-
restricting position can cause cavitation and major wear of the
products that will lead to leakage and malfunctions. This type of
underground fire hydrants is suitable only for “OPEN-CLOSED”
operation.
Negative pressure levels (cavitation) are to be avoided at all costs.
Extending the operating elements, e.g. with levers or similar
devices is not allowed.
Do not exceed temperature limits for the flow media.
Do not exceed permisable operating pressure. The closed valve
may only be loaded up to the allowable operating pressure.
For the version with the cone fully encapsulated in EPDM, the
EPDM parts must not be allowed to come into contact with
any medium containing oil or grease, as EPDM swells in those
circumstances.
Whatever the materials that constitute it, it is absolutely
forbidden to use our underground fire hydrants with gaseous
fluids such as propane, butane, natural gas or with hydrocarbon
fluids like petrol, diesel, etc.
2.6 Marking

3 -TRANSPORT,
HANDLING AND
LIFTING
The hydrant must be transported in the proper packaging to
guarantee protection against external damage and bad weather.
In case of severe climate conditions, special plastic-sealed
packaging with desiccant products must be used.
Transport must be carried out carefully in order to avoid shock
and any kind of damage, especially to the coating. Careless
handling may cause damage to the hydrant. Prior to mounting,
such damage is to be repaired in an appropriate manner.
During the transport, the hydrant is delivered in the closed
position.
Check the weight of the hydrant, in this document, (table 3)
before commencing any operations. Hydrants too heavy to be
handled manually must be transported by means of a lifting
device suitable for the weight involved (e.g. broad belts). Avoid
use of chains and ropes, in order to protect the hydrants from
coating damage. The lifting device must:
• be placed securely around the body , respecting the center of
gravity,
• using the special lifting lug on the body of the hydrant.
It is forbidden to attach the lifting gear to the square cap, the
outlet claw or in the flange holes, as this would be contrary to the
relevant safety regulations.
WARNING
Follow the applicable safety
regulations and wear the required
personal protective equipment.
WARNING
Failure to use suitable load
carrying devices for transport and
installation of hydrants can be
dangerous to health and safety.

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 installation, refer to
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.
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:

• Set up the bolts,
• Tighten them by hand,
• Tighten bolts gradually in a star-shaped pattern (see figure
6 – order from 1 to 8).
• At the end, tighten the connecting bolts evenly, without
distortion and crosswise, under a torque between 100 and
120 Nm. The value must not exceed 70% of the limit of
tightening torque of the bolts used.
Once the hydrant is assembled, the threads of the bolts/rods
should be greased with a brush or spray. MOLYCOTE or a similar
graphite based waterproof grease should be used to prevent
corrosion and facilitate subsequent dismantling operations.
After installation and before backfilling the trench and the
hydrant, perform a pressure test and functionality test (open and
close the hydrant) under pressure.
During backfilling of the hydrant, an adequate and sufficient
draining area must be established directly all around the hydrant
at the level of the two drainage devices, in order to allow the
emptying of its water volume. It may consist for example of an
adequate volume of pebbles, packed gravel, crushed rock or
any other appropriate means. When complete installation of
the hydrant is finished check that the drainage of the hydrant is
working perfectly by verifying that the hydrant empties after an
operation of opening/closing.
6 - COMMISSIONING
AND OPERATION
WARNING
Before installation, refer to technical
leaflet W331 from DVGW for deployment,
installation and implementation.
Before the hydrant is commissioned and installed, it must be
subject to a visual check. After installation, the hydrant must
be checked for movement of the inner valve: turn the square
cap over the total stroke (OPEN-CLOSE).
Each hydrant must be operated in respect of the operating
torque by a key according to DIN 3323-C.
Over-torque on the hydrant is strictly prohibited. According to
DIN standards, you will find in the table below the Maximum
Operating Torque (MOT) and Minimum Strength Torque (MST)
in Nm for gate underground fire hydrants to be operated by
key according to DIN 3323-C (see table 4). Operation by other
means or "Ring key and bar" is strictly prohibited.
Closing or opening operation of the hydrant must be done
under a torque that do not exceed the MOT stated in the table
below. In any case it is recommended to:
- turn 1/4 turn back after a complete opening operation,
- turn 1/4 turn back after a complete closing operation.

WARNING
Excessive torque may damage the hydrant body and
result in uncontrolled water leakage of up to 16 bar. In
this case, further work on the hydrant must be stopped
immediately and a safe distance to the hydrant must be
maintained, especially directly above the hydrant. The
isolating valve installed upstream of the hydrant must be
closed immediately in order to stop the supply of water.
If the torque necessary to close the hydrant is above
MOT values, plan a maintenance phase on the hydrant.
In case of over-torque applied to the hydrant, a proper
maintenance must be done including replacement of
the damaged components.

7 - MAINTENANCE
7.1 Maintenance recommendations
If they are used correctly, our underground fire hydrants are
maintenance-free. However, the performance and operating
conditions of parts of the system must be checked at regular intervals.
Visual and functional inspections and the resulting maintenance
work on the hydrant must only be carried out by qualified persons
(DVGW W400-3 (A)) and must be documented. In accordance with
DVGW leaflet W 392 / W331, monitoring of the functional capability
and tightness at MOT should take place at regular intervals, at least
≤4 years with regard to:
• Visual inspection to the maximum extent (integrity of corrosion
protection, presence of the identity disc, integrity of the claws for
the standpipe insert, complete emptying of the body, the condition
of the foreign matter deflector and / or presence and correct seat
of the cover of the claw, etc).
• Functional inspection by opening and closing the valve over an
entire stroke (easy mobility of the shut-off, complete emptying of
the body, …).
• Check for smooth operation and tightness at MOT values.
If the torque necessary to close or open the hydrant is above MOT
values, a proper maintenance must be done including changes of the
damaged components.
The operating/maintenance visits must be increased to an adapted
frequency if the gate valves are used with raw water or water that
tends to form deposits (limestone, etc) and incrustations, or in the
case of highly abrasive water, strong hydraulic conditions, strong
environmental variations.
Lubricant/grease must be approved for potable water application, and
must be appropriate to the functions it must fulfill. Recommended
lubricants for all types of maintenance (see paragraph 7.3) and for
flow medium water is: Klüber Synth VR 69-252 as unique grease
(silicone-free lubricant).
NOT ALLOWED OPERATION
Continuous operation in throttle position leads to
cavitation damage due to the high flow velocity.
An extension of the operating key by use of a lever
or similar is not allowed.
It is not permitted to open the hydrant against a
closed inspection or revision valve.
Do not exceed operating temperature limits and
operating pressure limits.
Closed valve may only be loaded up to nominal
pressure.
To avoid overpressure in the body and thus damage
to the shut-off cone insert, do not close the hydrant
against a closed standpipe or a closed outlet fitting.
The nominal pressure in the pipeline should not exceed the allowable
operating pressure that the hydrant can support.
On our hydrant, the materials and the corrosion protection are resistant
to the commonly used disinfectant products. Take care not to affect
hydrant materials when using cleaning / disinfecting products.
TO OPEN
• Carry out traffic safety procedure.
• Clean the outside street cap area of road dirt.
• Loosen the tight-fitting cover of the street cap, if necessary use a
suitable cover lifter.
• Take out the cover and swing it sideways.
• Clean the claw and the claw-cover of dirt, then lift the cover, then
rinse it without the standpipe.
• Insert the standpipe with the claw nut screwed down into the claw
and turn it to the right until fixed and tight seating is achieved.
• Fully open the outlet of the standpipe so that the air can escape
when the hydrant is opened.
• Turn the key C (according DIN 3223) slowly, anti clockwise till the
water flushes and clean the hydrant and the standpipe with the
escaping water.
• Close the outlet fitting on the standpipe and connect the hoses.
• Open the outlet fitting on the standpipe in order to get water.
WARNING
If this order is not followed, there is a risk
of polluting the drinking water.
TO CLOSE
• With the outlet fitting slightly open, close the hydrant completely
by turning clockwise till the stop. Then it`s recommended to turn
¼ turn to the left to decock the inner valve. If the outlet fitting
of the standpipe is not open at the closing process, a positive
pressure may build up. If necessary , unscrew the hoses
(uncoupling).
• Once the hydrant is closed, loosen the standpipe by turning to
the left.
• Observe whether the water level in the body drops during
emptying.
• Close the claw with his cover
• Close the street cap
• Remove traffic safety

Our underground fire hydrants are maintenance free.
However, the complete bonnet, the operating inside trim, and
the complete outlet claw (including foreign matter deflector
and cap) can be removed and installed from the road through
the street cap (see section 7.4 for composition of spare parts
set). In the event that it is necessary to replace any part of
the hydrant, follow the instructions below. Replacement of the
shut-off ball, inlet flange gasket or drain tube can be done only
if the hydrant is totally disassembled from the water network.
7.3 Replacement
WARNING
Before carrying out inspection or any repair work on the
hydrant, the pipe section in which the hydrant is installed
must be depressurized and safe, e.g. by closing the gate
valve and emptying. A built-in double shut-off and / or
closed gate valve installed upstream of the hydrant are
no guarantee that the hydrant inside is depressurized.
After maintenance works, when putting back under
pressure, it is essential to operate the hydrant very
slowly when opening because some air under pressure
might have become trapped.
