Safety Notes

Prior to assembly and commissioning to avoid injury of persons and

damages of the devices, it is absolutely necessary to carefully read and observe these instructions.

Necessary assembly, start-up, and maintenance work must be performed only by qualified, trained and authorized personnel.

Prior to assembly and maintenance work on the controller, the system must be:

- depressurized,

- cooled down,

- emptied and

- cleaned.

Please comply with the instructions of the system manufacturer or system operator.

Definition of Application

The controller is used for differential pressure relief control of water and water glycol mixtures for heating, district heating and cooling systems. The technical parameters on the product labels

determine the use.

Assembly Admissible Installation Positions ❶

Medium temperatures up to 100 °C:

- Can by installed in any position. Medium temperatures > 100 °C:

- Installation permitted only in horizontal

pipelines with the actuator oriented downwards.

Installation Location and Installation Scheme ❷

AVPA by-pass mounting

Valve Installation ❸

1. Clean pipeline system prior to assembly.

2. The installation of a strainer ① in front of the

controller is strongly recommended.

3. Install pressure indicators in front of and

behind the system part to be controlled.

4. Install valve

• The flow direction indicated on the product

label ② or on the valve must be observed ③.

• The valve with mounted weld-on tailpieces

may only be spot welded to the pipeline ④.

The weld-on tailpieces may be welded only

without the valve and seals! ⑤⑥

If these instructions are not observed, high

welding temperatures may destroy the seals.

• Flanges ⑦ in the pipeline must be in parallel

position and sealing surfaces must be clean and without any damage.

Tighten screws in flanges crosswise in 3

steps up to the maximum torque (50 Nm).

5. Caution: Mechanical loads of the valve body by the

pipelines are not permitted ⑧.

Insulation ❹

For medium temperatures up to 100 °C the pressure actuator ① may also be insulated.

Start-up ❺

The valve is closed without pressure . The valve opens when the d ifferential pressure ① rises above the adjusted set-point.

Filling the system, first start-up

1. Slowly open shut-off devices ② in the flow pipeline.

2. Slowly open shut-off devices ③ in the return pipeline.

Leak and Pressure Tests

Pressure must be gradually incre ased at the +/- connection ①.

Non-compliance may cause damages at the actuator or the valve. A pressure test of the entire system must be carried out in accordance with manufacturer’s instructions. The maximum test pressure is:

1.5 × PN

PN - see product label !

Putting out of operation

1. Slowly close shut-off devices ② in the flow pipeline.

2. Slowly close shut-off devices ③ in the return pipeline.

Settings ❻ Differential Pressure Setting

The diff. pressure setting range is indicated on the product label ①.

Procedure:

1. Start system, see section “Filling the system, first start-up“.

Completely open all

shut-off devices in the system.

2. Start pump operation ②

3. Adjustment Observe pressure indicators ③ or/and alternatively see handle scale indication.

Increase the setting ④ (stress the spring):

PN16 turn to the right (clockwise), PN25 turn to the left (counter-clockwise).

Decrease the setting ⑤ (relieve the spring):

PN16 turn to the left (counter-clockwise), PN25 turn to the right (clockwise).

Seal ❼

The set-point adjuster can be sealed by a seal wire ①, if necessary.

Sikkerhedsnoter

Disse instruktioner SKAL læses omhyggeligt forud for montering og

indkøring samt respekteres for at undgå skader på personer og udstyr. Nødvendigt monterings-, opstart- og vedligeholdelsesarbejde må kun udføres af faglært og autoriseret personale.

Forud for monterings- og vedligeholdelsesarbejde på regulatoren skal systemet være:

- trykløst,

- nedkølet,

- tømt og

- rengjort.

Systemproducentens eller -operatørens instruktioner skal overholdes.

Anvendelse

Regulatoren anvendes til styring af differenstrykaflastningen af vand og vandglycolblandinger til varme-, fjernvarme- og kølesystemer. De tekniske parametre på produktetiketterne

fastlægger anvendelsen.

Montering Tilladelige installationsstillinger ❶

Medietemperaturer op til 100 °C:

- Kan monteres i alle stillinger. Medietemperaturer > 100 °C:

- Må kun installeres i vandrette rørledninger

og med aktuatoren hængende nedad.

Installationsplacering og installationsplan ❷

AVPA by-pass-montering

Ventilinstallation ❸

1. Rengør rørledningssystemet før montering.

2. Det anbefales stærkt at installere et filter

foran regulatoren ①.

3. Installer trykvisere før og efter den

systemdel, der skal reguleres.

4. Installer ventilen

• Den flowretning, der vises på

produktetiketten eller på ventilen, skal respekteres ②③.

• Ventilen med monterede svejsestudser

må kun klemmes fast til rørledningen ④. Svejsestudserne må kun svejses uden ventil og pakninger! ⑤⑥

Høje svejsetemperaturer kan ødelægge

pakningerne, hvis disse instruktioner ikke overholdes.

• Flanger ⑦ i rørledningen skal være placeret

parallelt, og pakfladerne skal være rene og uden skader. Krydsspænd skruerne i flangerne i 3 trin til maks. moment (50 Nm).

5. Forsigtig:

Rørledningerne må ikke belaste ventilhuset mekanisk. ⑧

Isolering ❹

Ved medietemperaturer op til 100 °C kan trykaktuatoren ① også være isoleret.
