Installation
The instrument can only be installed by trained personal.
Check tread of the pressure ports and fittings before installation and make sure they
are clean and not damaged.
Tapered NPT treads usually are screwed in together with Teflon tape to protect against
galling and to improve sealing. It is important that no remains of the tape are able to
get into the interior of the pressure limiting valve.
• If the pressure limiting valve is used is a pressure system and is attached to tubing,
attach the pressre limiting with a M5 screw to a frame, bracket, etc to relief the weight
of the pressure relief valve on the tubing.
• Connect the supply port with 1/4 NPT male coupling.
• Connect the outlet port with 1/4 NPT male coupling or manometer.
Be careful when you are working with high pressure.
