- Bring the probe heads of the T probe (10) and RH probe (11) together as shown below. Insert the screw sleeve (7) over the probe heads and connect the probe cables together with the sealing rubber (6).
- Insert the first tube (5) over the probe heads and tighten it to the screw sleeve (7). Insert the small white plastic support (4) to the cable at the base of the RH probe head. Route the cable of the T probe head so that it rests in the cutout of the support. Push the screw sleeve so that the support goes inside the tube.
- Tighten the RH measuring tube (3) over the RH probe head. This is the tube with most holes on the sides.
- Insert the grommet (1) to the hole at the end of the T measuring tube (2). Then push the T probe head through the grommet and tighten the tube.
