The Eurovac HV leak detector generates a constant vacuum in the
interstitial space of the tank and triggers an alarm if the vacuum
drops.
Eurovac HV contains the following elements in an impact-resistant
plastic housing: display elements and controls, a vacuum pump, a
pressure switch, a printed circuit board with the electronic compo-
nents for processing the output signal, a filter and three hose con-
nections for the pneumatic connection to the interstitial space of the
tank.
The green LED “Supply ON” lights up when mains voltage is avail-
able. The alarm is indicated visually and audibly and is made avail-
able via a voltage-free relay contact (1 changeover contact).

Product description
3.1 Function
Via the suction line, the vacuum pump installed in the leak detector
generates a vacuum in the interstitial space of the tank. The pres-
sure switch measures the pressure in the interstitial space via the
measurement line and keeps it at a constant level together with the
vacuum pump.
If a leak occurs in the tank's wall or in the leak protection lining (in
the inner or outer wall of the tank) either above or below the level of
the stored liquid or the ground water, and if this leak is greater than
the pump's suction capacity, the vacuum will drop. When the alarm
threshold is reached, the red LED “Alarm” and the audible alarm are
activated and the relay is energised. The audible alarm can be
muted with the button “Mute”.
3.2 Operating modes
Eurovac HV is equipped with an output relay to transmit the alarm
signal to additional external devices. If no error condition is present,
the relay is de-energised. In the case of an alarm, the relay is ener-
gised.
Eurovac HV can be operated with or without additional external de-
vices. The following types of additional devices can be used: visual
and audible alarm units, telecommunication devices, building control
systems, building automation systems, etc.

6 Mounting and commissioning
The leak detector may only be installed and commissioned by a spe-
cialised company, see chapter 2.4, page 6.
6.1 Preparing the tank
Tanks whose interstitial space is still (partially) filled with leak
detection fluid
1. You need a collecting container (bucket with a capacity of at
least 10 l), a vacuum pump (min. capacity 1.5 m³/hour) to re-
move the liquid from the interstitial space and a carboy with a
capacity of at least 10 l.
2. Disconnect the connection line of the leak detection fluid con-
tainer from the tank.
3. Collect the escaping leak detection fluid in the bucket.
4. Dismount the test valve, the connection line and the container
for the leak detection fluid with the plug-in probe.
5. Clean the 1" threaded sockets for the leak detection fluid con-
tainer and the test valve and mount/seal suitable adapters and
hose connection pieces so that the suction hose and measure-
ment hose of the Eurovac HV can be connected.
6. Insert two hoses into the carboy neck and seal them (suction
hose pump, suction hose tank). Leave the hose connection for
the measurement line open for the time being so that air can be
admitted.
7. Suck the leak detection fluid from the interstitial space into the
carboy until the liquid column becomes unstable and air is with-
drawn. Remove the maximum possible volume of liquid from the
interstitial space, but at least the following volume:
Eurovac HV 13

Mounting and commissioning
Table 2: Minimum volume to be withdrawn
Tank capacity Minimum volume to be withdrawn
1-5 m³ 5 l
7-13 m³ 10 l
16-30 m³ 15 l
40-60 m³ 30 l
80-100 m³ 35 l
8. Connect vacuum gauges to the measurement connection.
9. Keep withdrawing at a vacuum of -0.5 to -0.8 bar.
10. It is absolutely indispensable for the top area of the tank to con-
tain air. When the pumped volume decreases, interrupt the
pumping process several times so that additional liquid can flow.
If the suction volume becomes too small, alternating withdrawal
via the measurement connection may prove to be more suc-
cessful.
11. Always make sure to withdraw the maximum volume possible,
but at least the volume specified in table 2so that a sufficient air
volume is created above the remaining liquid.
12. Dismount the pumping equipment.
6.2 Preparing mounting
Basic vacuum
The vacuum pump of the leak detector must not exceed the pump
capacity of 100 l/h.
 Generate a vacuum of approx. -400 mbar in the interstitial
space. Use an installation pump with a greater capacity for this
purpose.
Leak test
 Check for leaks in the interstitial space.

A slight pressure drop in the first hour is unavoidable. After that,
there should be no noticeable pressure loss.
Adaptation
 Reduce the vacuum in the interstitial space to -370 mbar.
If the vacuum is greater when the leak detector is connected,
the measuring system may be damaged or destroyed.

Mounting and commissioning
6.3 Installation site
 Choose an installation site that is as close as possible to the
tank to be monitored. The ambient temperature specified must
not be exceeded.
 Mount the leak detector to an even, rigid and dry wall at eye
level.
 The leak detector must be accessible and easy to oversee at all
times.
 The leak detector must not be exposed to water or splash water.
 Do not mount the leak detector in damp rooms.
 The leak detector must not be installed in hazardous areas or in
access chambers of underground tanks.
 If the case of outdoor applications, the leak detector must be
mounted in a protective housing with IP 55 protection. If the leak
detector is installed in a protective housing, an additional
weather-proof audible alarm must be installed outside of the
protective housing. See chapter 11, page 27 for accessories.
 If the leak detector is installed below rooftops or in rooms that
are only partially closed, protect it against direct atmospheric in-
fluences or use a protective housing as mentioned above.
6.4 Installing the leak detector
1. Fasten the leak detector the wall (use Aor B),
a drilling template is included.
Eurovac HV 15

Mounting and commissioning
2. Open the leak detector.
3. Connect the unit electrically as described in chapter 6.5 on
page 16.
4. Close the leak detector.
6.5 Electrical connection

Mains voltage is interrupted and cannot be switched on by acci-
dent.
 Connect the leak detector directly to the supply network without
a switch and without a plug!
 If you want to route the mains or relay cable trough the top of
the housing, replace the rubber grommet at the top of the hous-
ing by the enclosed cable gland.
 Close any cable glands at the bottom of the housing that are not
used by means of the enclosed plugs.

Power supply
Connect the leak detector to mains by means of a permanently in-
stalled cable such as NYM-J 2 x 1.5 mm².
1. Route the mains cable through the upper or bottom cable gland
into the leak detector.
2. The phase must be connected to terminal L1, the neutral con-
ductor to terminal N. The leak detector supply cable must have
a separate fuse (max. 16 A).
Output
The output signal of the leak detector is made available via a volt-
age-free relay contact (1 changeover contact).
 Permanently install the relay cable, route it through the upper or
bottom cable gland into the leak detector and connect it to the
terminals with the corresponding designations.
 Safely isolate the relay cable. The isolation characteristics of the
relay cable must at least comply with IEC 60227 or IEC 60245.
If no error condition is present, the relay is de-energised. In the case
of an alarm, the relay is energised.
Eurovac HV 17

Mounting and commissioning
CAUTION
Destruction of the switching contact and adverse effects on the
function of electrical systems due to voltage peaks when induc-
tive consumers are switched off.
 Use commercially available standard RC combinations such as
0.1 µF/100 Ohm for inductive consumers.
9 V battery for alarm in the case of power failure
If a standard 9 V battery is connected, an alarm sound is activated in
the case of a power failure. The alarm sound cannot be muted; it re-
mains on until mains power is available again. When mains power is
available again, the device immediately resumes operation. If a leak
has occurred in the meantime, this is indicated.
6.6 Hose connections
Hoses from the leak detector to the tank to be monitored, see also
fig. 3, page 10.
1. Use pressure-proof, oil- and water-resistant plastic hoses
6 x 2 mm for the measurement hose (red), the suction hose
(transparent) and the exhaust hose (green).
When the leak detector of existing systems is replaced, you may
also use 4 x 2 mm provided such hoses had been used before
the leak detector is replaced.
The hose connection pieces of the device are designed for
18 Eurovac HV

Mounting and commissioning
4 x 2 mm and 6 x 2 mm hoses.
2. The hoses must have the full cross section over the entire
length, there must be no bends and indentations.
3. The hoses should have a steady gradient from the device to the
tank.
In the case of outdoor tanks, install the hoses with a steady gra-
dient of 4 %.
4. If a steady gradient to the tank cannot be maintained, install a
condensate trap at the lowest point.
5. Do not fit any shut-off elements.
6. In the case of underground or outdoor installation of the hoses,
route the hoses through impact-resistant and weather-proof pro-
tective pipes.
7. Connect the measurement hose to the measurement connec-
tion of the tank.
8. Connect the exhaust hose to the tank vent pipe.
If an AFRISO Euroflex withdrawal system is used, the exhaust
hose can be directly connected to the Euroflex return connec-
tion in the case of single-line operation.
9. Connect the suction hose to the suction connection of the inter-
stitial space. A liquid barrier must be installed in the suction
hose. The liquid barrier must be mounted vertically, e.g. at the
manhole cover.
10. Secure all transition and connection points of the hoses by
means of hose clamps that have contact around the entire cir-
cumference of the hoses.
