Low pressure regulator Type FL 90-4, Type FL 91-4
part no. 05 004 52 b
5 / 12
Filter screen in the inlet connection of the pressure regulator
LPG may contain foreign matter, such as dirt particles. Over a certain size, these particles are
trapped in the filter screen in the inlet connection. If the LPG is not filtered, wear and tear of
the LPG system is increased up to complete failure. See TROUBLESHOOTING.
Test connector option
A leak tester can be connected to the test connector
for pressure and leak tests. First, loosen the set
screw in the test connector. When you have used it,
tighten the set screw again and check for leaks again.
See LEAK CHECK.
Insect protection with sieve
Insert in the breather on the 8 mm vent socket or screw into the female
thread G 1/8.
Check regularly that the sieve is not blocked. A blocked sieve can increase or
lower the outlet pressure and cause the safety overpressure shut-off valve (OPSO) to
respond. Clean or replace it as required.
