–   The gas meter marked with 

 must be in-

cluded in the equipotential bond when being 
installed in a potentially explosive atmosphere, 
e.g. by connecting it to a grounded pipeline. 
Installation must be carried out in accordance 
with EN 60079-14.

–   The gas meter marked with 

 must be pro-

tected from falling parts.

 

  If the calibration seal has been damaged or re-

moved, the gas meter is no longer approved for 
measurements which are subject to statutory 
testing. 

 

If the gas meter is stored or installed outdoors, 
protect the site against rain. Condensing humid-
ity is permitted.

    

Remove protective caps.

 

Installation in the horizontal position: connectors 
must be pointing upwards.

 

Note direction of flow (arrow).

 

The gas meter must not be in contact with ma-

sonry or other parts.

 

Ensure that there is sufficient installation space.

 

Ensure unobstructed view of the index.

 

The seal faces on the screw unions must be 

clean and damage-free.

 

For the compression of seals and the resulting 
tightening torques for the screw unions, the seal 
manufacturers’ specifications must be observed.

 

 Tightening torques for the recommended flat 

seals in conjunction with screw connectors 
pursuant to DIN  3376-1 and  3376-2, see

 Secure each of the temperature sensors using 

the capstan screw provided.

Connecting the pressure measuring 
line

 WARNING

In order to ensure that the gas meter is tight:

–   The pressure test nipple must not be twisted, 

bent, or otherwise manipulated.

–   When installing, always secure the pressure test 

nipple using a suitable spanner.

 

Functional safety and reliability are ensured only if 
the material combination of the screw connector 
and the pressure line are inter-matched.

 

Only use the olive and the attached union nut 
supplied. The olive is secured to the sealing 
sleeve.

 

When re-ordering, use original Parker EO pro-
gressive ring fittings PSR/DPR.

Use corrosion-resistant, seamless precision steel 
tube pursuant to DIN EN 10305-4 (external di-

materials, use a suitable adapter and note the 
Parker/EO recommendations.

 

Install pipes free of mechanical stress.
