Ensure cleanliness of the sealing areas. Remove protective packaging only just before mounting.
In case of damaged sealing areas replace the unit or the adapter.
5.5.1 Installation LMT01A (hygiene-compliant)
The seal is formed by the flush front of the PEEK sealing cone (2).
u
If required: Slide the supplied seal (black O-ring), (1) over the thread onto the sensor and/or check
for correct position. It seals the gap on the back between the sensor and the adapter to protect
against the ingress of contamination in the thread area.

The seal between the housing and the process connection (1)
can compensate for variable insertion depths but not for the
system pressure.

If required: Lightly grease the thread using a suitable lubricating paste which has been approved
for this application.

Screw the sensor into the respective process connection and tighten it.
Maximum tightening torque: 20...25 Nm

After installation check the tank / pipe for ingress resistance.
5.5.2 Installation LMT03A and LMT04A
The unit can be adapted for hygienic zero-leak via two sealing versions: Flush mount zero-leak using
metal-to-metal sealing (fig. LMT seal, metal-to-metal), or via insertion of an additional PEEK gasket
(fig. LMT seal, PEEK).
The PEEK sealing ring is not supplied with the unit. It can be ordered separately (E43323).
The PEEK sealing ring has been rated for ifm adapters with end stop towards the medium.
If the sealing between the housing and the process connection ((1) in fig. LMT seal, metal-to-
metal) is to withstand the system pressure, no end stop for the flush mount sealing area exists.
u
In this case, the PEEK sealing ring must not be used.
Flush mount hygienic zero-leak using metal-to-metal sealing (2):
