2.5 Mounting and dismounting
The following instruction is to be used when it is necessary to mount or dismount the
OPTIPROBE measuring sensor (model B only !).
Dismounting
1. Make sure that the safety chain is correctly installed to secure the OPTIPROBE
2. Loosen the bolt
1
in picture below, until the unit can be slided out of the gland. Be aware that
if the pressure is sufficiently high the unit can slide out without pulling, or even force out when
pressure in the installation is high.
3. Slide out the OPTIPROBE unit as far as possible (allowed by the chain).
4. Close the valve. Remind that the volume above the valve is still pressurized.
5. Loosen the bolts
2
in picture below, to release pressure.
6 Dismount the chain and remove the OPTIPROBE.
Mounting the OPTIPROBE
1. Loosen the bolt
1
in picture above, until the unit can be slided in the gland.
2. Loosen the bolts

4. Tighten the bolts
2
in picture above. Be sure the safety chain is attached and the bolts are
tighted !
5 Carefully open the valve.

pressure in the installation.
