P1.1, P1.1E
Before installing the replacement part remove any rust residue on the motor shaft and coat with non-resinous oil.
Reinstall the set screw with a drop of medium-strength threadlocker. When tightening the set screw, be sure it is seated in the
locking hole on the shaft. Once it touches the bore, tighten the set screw 90° more.
6.6 Assembly of the sample gas pump
If the sample gas pump was removed, install in reverse order. Be sure the sealing surfaces of the below and pump head are clean
and aren’t scratched (even minimal grooves can cause leaks). First evenly tighten the 4 Torx screws M4x18 at 1 Nm. Then tighten
the screws to 3 Nm.
CAUTION! Tighten each screw only once at 3 Nm. The bellow and pump body material (PTFE) is very weak and has high flow
properties.
Check the sample gas pumps for tightness and proper function.
