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.
