TRÖ DIN 4755, TRÖl or supply systems according to TRöL (Austria) for fuel oil consumer

installations according to DWA-A 791 (TRwS 791-1, draft),

 an anti-siphon device according to EN 12514-2: 2000-03,

 a shut-off device in terms of VAwS that prevents siphoning,

 a safety device as "protection against siphoning" according to worksheet DWA-A 779 for

liquid substances that are hazardous to water,

 a construction product according to Building Rules List A Part 1 (edition 2012/1) No. 15.41

with attachment 15.14 with the general technical approval Z-65.50-492,

 an odour free fitting, quality label PROOFED BARRIER

SAFETY DEVICE AGAINST SIPHONING

There is a risk of liquid fuels escaping while the burner/pump is not operating due to the

pressure of the fuel column in the suction line if:

 the minimum liquid level in the tank is above the lowest point in the suction line (∆H),

 a feed line is below the highest level of the operating tank of a pump unit.

This is described as siphoning. A safety device against siphoning prevents this.

Pos: 27 /Anleitungen A5/ Öl/Hebersicher ung/Wirkungsweise @ 0\mo d_1304585519256_817.d ocx @ 11208 @ @ 1

PRINCIPLE OF OPERATION

 If the feed system is not operating, the suction line is blocked by the spring-loaded valve in

the HS-V.2.

 This valve opens with the vacuum generated when the pump unit starts up.

 If there is a leak in the suction line when the burner is not operating, the HS-V.2 remains

closed and thus prevents fuel escaping.

 The HS-V.2 is equipped with an integrated safety device against excess pressure – known

as a pressure relief valve. If, while the system is not operating, the pressure rises due to a

rise in temperature, for example, the valve opens towards the tank in relation to the safety

level that is set, approx. 0.2 ÷ 2 bar.

Pos: 48 /Anleitungen A5/ Öl/Hebersicher ung/Montage/Einbau Dom schacht / Förderaggregat @ 0\ mod_1304599874132_8 17.docx @ 11419 @ @ 1

Installation in a dome

Install the product horizontally so that the top with the ventilation opening for the membrane

faces downward. This allows any condensation that forms to run out.

Recommendation: Install a filter.

NOTE

Installation behind pump units with an operating tank.

The actual height difference ∆X is the difference between the installation position of

the HS-V.2 behind the pump unit and the lowest point in the suction line.

Pos: 49 /Anleitungen A5/ Öl/Hebersicher ung/Montage/Auswah l HA Punkt 1-3 @ 0\mod_130459581 8473_817.docx @ 11374 @ @ 1

Adjusting the anti-siphon device - HA according to the actual height difference X

For the height setting HA of the HS-V.2, the actual height difference X is decisive. If the

height X is greater than HA, the pressure of the fuel column behind the anti-siphon device is

higher. The opening pressure p

o,o

must therefore be higher than the pressure of the fuel

column for the HS-V.2 to function properly.

NOTE

Operating safety: Adjust HA so that the actual height difference X is just

safeguarded.

Higher HA values lead to greater opening pressures p

o,o

and, consequently, to higher

vacuums in the suction line and increased formation of gas bubbles.

1. Measure the height difference X between the installation position of the anti-siphon

device and the lowest point of the suction line – generally, the hose on the floor in front of

the point of consumption.

The setting for the safety level according to Points 3 and 4 applies for fuels with a

maximum density of ≤ 860 kg/m³, e.g., fuel oil EL.

2. Set the correct safety level from the measured height difference X:

3. Set measured height difference X ≤ HA on the scale using the handwheel (see

OPERATION).

NOTE

4. If the density of the operating medium is greater than 860 kg/m³, a conversion to

the corrected height setting HA is required. A higher vacuum is generated in the

liquid column p

o,g

. The density of the stored operating medium must be known.

Ask your mineral oil merchant. If the safety level is not corrected, there is no

protection against siphoning.

Set the safety level HA as follows:

in kg/m³

NOTE

If the density of the operating medium is less than 820 kg/m³ the setting for the

safety level can be reduced when HA* has been determined. This is beneficial in case

of larger height differences to reduce the vacuum in the suction line.

5. To check the anti-siphon device, refer to FUNCTION CHECK.*)

NOTE

When the specified closing moment is reached, the handwheel can be turned

freely.

When the supply system is running, the product may not be operated at the following

positions:

"Ventilate": The anti-siphon device is deactivated, the suction line is not protected.

"Block": The anti-siphon device is blocked and does not open in case of a vacuum. This

position enables maintenance work to be carried out on the suction line, for example.

NOTE

Never start the burner pump in the "block" position.

The burner pump may be damaged or it can become too hot and malfunction.

1. Make sure that the burner pump runs only in the "operation" position.

Check HS-V.2 at appropriate intervals, at least every 5 years:

 Proper installation position (see Figure 1).

 Check that the safety level HA matches the actual height difference ∆X.

 Switch the pump on an off several times. While doing so, make sure that the anti-siphon

device closes and opens.

 Carry out a FUNCTION CHECK.

REPAIRS

If the measures explained above under START-UP and OPERATION do not result in regular

START-UP, and if there is no dimensioning problem, the product must be sent to the

manufacturer for a check. Our warranty does not apply in cases of unauthorised interference.

Pos: 64 /Anleitungen A5/ Öl/Hebersicher ung/Instandsetzung / Reparatur @ 0\mod_130460714 0347_817.docx @ 11554 @ @ 1

The product may be cleaned and maintained only by companies such as those

described in INSTALLATION.

If the burner malfunctions during operation  carry out a check:

 Check for leaks at the connection elements of the anti-siphon device:

Is the o-ring in a good condition?

In copper pipes, is the compression fitting with reinforcing ring okay?

 Choose the correct inside diameter of the piping:

Choose the inside diameter to suit the actual flow rate.

 Measure the suction pressure at the burner pump with the specification pPump  - 400

mbar.

Is it > 400 mbar?

 Check for leaks and/or check the height setting HA

 Reduce any excess heights in the piping (max. 4 m)

 Reduce pressure loss in the suction line, e.g. with different fittings, elbows, etc.

 Check for contamination in the complete suction line, rinse if necessary

 Height setting HA corresponds to the actual height difference ∆X.

The anti-siphon device must be replaced with a new one:

 after flooding,

 if fuel escapes from the anti-siphon device.

In the event of inadmissible operating pressures > 10 bar caused by temperature-related

changes in volume, the membrane is destroyed, which, in turn, destroys the anti-siphon

device.

Replacement

According to DIN 4755, membrane-controlled components, such as safety fittings against

siphoning, must be replaced every 10 years at the latest. Replacement is not necessary if it is

confirmed that the product still functions properly.

NOTE

In case of flooding, the anti-siphoning protection is reduced.

For each metre of water column above the membrane-controlled anti-siphon device

HS-V.2 the protection against siphoning is reduced by 1.50 m on average.

No safeguard is guaranteed then.
