INSTALLATION

IMPORTANT IMPORTANT
Take care that installer is a trained experienced
service man.
Turn off gas supply before starting installation.
Disconnect power supply to prevent electrical shock
and/or equipment damage.
Do not remove seals over inlet and outlet until the
device is ready to be installed.
Take care that dirt cannot enter the gas control during
handling.
Mounting position
The gas control can be mounted 0 to 90 degrees in any
direction from the upright position (from the position when the
operators are on top).
Main gas connection
Gas controls with internal thread
• Take care that dirt cannot enter the gas control during
handling.
• Use a sound taper fitting with thread according to ISO 7-1
or a piece of new, properly reamed pipe, free from swarf.
• Do not thread or tighten the pipe or pipe fitting too far (see
table below). Otherwise 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.
• Tighten gas control using the right open end wrench. fig. 3
.
• Ensure the gas flows in the same direction as the arrow on
the bottom of the gas control.

for each flange.
