3.1.1 Installing a compact version

The pH transmitter can be easily installed
in pipes using our specially designed fitting
system. Remove protective cap from the
sensor and keep it for storage.
1. The fitting 4 must be installed into the
pipe according to the installation speci-
fications in section 3.1.
2. Insert plastic nut 3 into fitting, and let
plastic ring 2 snap into guide bush 5.
3. Carefully insert the pH transmitter 1 into
the fitting. If installed properly, the trans-
mitter cannot be rotated.
4. Tighten transmitter housing to fitting with
plastic nut 3.
Plastic nut must only be tighte-
ned by hand!
