direction of the gas flow.
Mounting position
To ensure perfect regulator operation, regulator
should be assembled horizontally. They can
however be installed in different positions up to an
angle of 90
°
.
Mounting location
Contact between the regulator and walls or a floor is
not permitted. Maintain a distance of at least 50
mm.
Note: In case of the HUPF Series, the distance
between the bottom and the ground must
be at least 400 mm, to facilitate filter
cleaning and inspection.
Main gas connection threaded regulators
•
Take care that dirt cannot enter the gas regulator
during handling.
•
Ensure the gas flow in the same direction as the
arrow on the housing of the gas regulator.
•
Use a sound taper fitting with thread according to
ISO 7-1 (BS21, DIN 2999) or a piece of new,
properly reamed pipe, free from swarf.
•
Do not thread or tighten the pipe or pipe fitting too
far. Otherwise regulator distortion and malfunction
could result.
•
Apply a moderate amount of good quality thread
compound to the pipe or fitting only, leaving the
two end threads bare. PTFE tape may be used as
an alternative.
•
In order to tighten the pipe in the regulator, do not
use the sleeve of the upper cover as a lever but
use a suitable wrench operating on the wrench
bosses.
