Start- up

Preparations for Initial commissioning

The compressor has undergone trials in the factory and all functions have been tested. 

There are therefore no special running-in instructions.

Before starting up, check the compressor for any signs of transport damage!

To protect the compressor from intolerable operating conditions, high- and low-

pressure pressostats. Comply with the accident prevention regulations!

Tightness test

 

Perform the tightness test of the refrigeration plant according to EN 378-2 (or a 

corresponding safety standard) 

without inclusion of the compressor

 (preferably 

dried with N2). 

 

Do not mix any artificially refrigerant (e.g. R134a, R404A,... ) with the testing 

medium, since otherwise shifting the ignition limit into the critical range is 

possible.

Since significantly greater standstill pressures than permitted for the compressor 

may arise, depending on the ambient temperature and refrigerant filling amount, 

suitable measures must be taken on site to limit the standstill pressure in the 

compressor to the permissible values (e.g. storage material, equalising reservoir, 

pressure-keeping refrigeration system, pressure relief devices).

Inbetriebnahme

Vorbereitungen zur Inbetriebnahme

Vorbereitungen zur Inbetriebnahme

Der Verdichter ist im Werk probegelaufen und auf sämtliche Funktionen geprüft worden. 

Besondere Einlaufvorschriften müssen daher nicht beachtet werden.

Vor Inbetriebnahme Verdichter auf Transportschäden kontrollieren!
Um den Verdichter vor unzulässigen Betriebsbedingungen zu schützen, sind 

Hoch- und Niederdruck-Pressostate zwingend erforderlich.

Unfallverhütungsvorschriften beachten!

Da in Abhängigkeit von Umgebungstemperatur und Kältemittelfüllmenge deutlich 

höhere Stillstandsdrücke wie für den Verdichter zugelassen, auftreten können, 

müssen anlagenseitig geeignete Maßnahmen ergriffen werden, die den Still-

standsdruck im Verdichter zuverlässig auf die zugelassenen Werte begrenzen 

(z. B. Speichermasse, Ausgleichsbehälter, Druckhaltekälteanlage, Druckentla-

stungseinrichtungen).

Druckfestigkeitsprüfung

Druckfestigkeitsprüfung

Der Verdichter wurde im Werk auf Druckfestigkeit geprüft. Sofern zusätzlich die gesamte 

Anlage einer Druckfestigkeitsprüfung unterzogen werden soll, ist zu beachten:

● 

Kältekreislauf gemäß EN 378-2 (oder einer entsprechenden Sicherheitsnorm) prüfen.

● 

Druckfestigkeitsprüfung vorzugsweise mit  trockenem Stickstoff durchführen.

● 

Verdichter in keinem Falle mit Luft abpressen.

●  Dem Prüfmedium kein künstliches Kältemittel 

(z.B.

 

R134a,

 

R404A

 etc.) beimischen, 

da sonst die Verschiebung der Zündgrenze in den kritischen Bereich möglich ist.

Gefahr! Während des gesamten Prüfvorgangs darf der maximal 

zulässige Betriebsdruck des Verdichters nicht überschritten werden 

(siehe Typschildangabe)!

Dichtheitsprüfung

Dichtheitsprüfung

  Dichtheitsprüfung der Kälteanlage

Dichtheitsprüfung der Kälteanlage gemäß EN 378-2 (oder einer entsprechenden 

Sicherheitsnorm)

ohne Einbezug des Verdichters

(vorzugsweise mit N

2

 getrocknet)

durchführen.

Dem Prüfmedium kein künstliches Kältemittel (z.B. R134a, R404A etc.) beimischen,

da sonst die Verschiebung der Zündgrenze in den kritischen Bereich möglich ist.

To protect the compressor from intolerable operating conditions, high- and low-

pressure perssostats are required. Comply with the accident prevention regulati-

ons!

).

Evacuation

  Firstly evacuate the plant, 

then include the compressor

 in the evacuation process.

- Pressure relieve the compressor

- Open suction and pressure shutoff valve.

- Evacuate with the vacuum pump on the suction and high pressure side.

- Vacuum < 1.5 mbar with shutoff pump. 

- Repeat the process several times if necessary.

Do not start the compressor in vacuum. Apply no voltage – also not for test 

purposes (may be operated only with refrigerant). 

In the vacuum the spark-over and creepage current distances of the terminal board 

connection bolts shorten, this can lead to winding and terminal board damage.

 

Firstly evacuate the plant, 

then include the compressor in the evacuation process. 

Check the compressor for any signs of transport damage!

Pressure strength test

The compressor was tested in the factory for pressure strength. If the entire plant should

be subjected in addition to a pressure strength test, then observe the following:

  Test the cold circuit according to EN 378-2 (or a corresponding safety standard). 

  Perform the pressure strength test preferably with dry nitrogen (N

2

). 

  Do not mix any refrigerant with the testing medium (N

2

), since otherwise shifting the 

ignition limit into the critical range is possible.

By no means the compressor may be pressure tested with oxygen or other 

industrial gases!

The maximum permissible operating pressure of the compressor may not be 

exceeded during the entire testing process (see name plate information)!

 

Do not mix any artificially refrigerant (e.g. R134a, R404A,... ) with the testing 

medium, since otherwise shifting the ignition limit into the critical range is 

possible.
