11. Protect the sensor’s membrane by placing the supplied plastic cap over the
sensor’s threads (see Figure 4)
5.4 Installing the Brass Adaptor onto the Valve
1. Wipe the inside of the transformer valve.
2. Cover the adaptor’s threads with PTFE tape; see Figure 12.
Use only PTFE tape to seal the threads of both the adapter and
the Hydran 201 sensor. Wrap at least 4 to 5 layers of tape
around the threads.
Always wrap the tape counter to the treads.
3. Screw the adaptor onto the valve and tighten it using a pipe wrench. Ensure
two of the screw holes of the adaptor (used to fasten the Hydran 201Ti’s
heating plate) are level (horizontal).
5.5 Installing the Hydran 201 Sensor
1. Cover the adaptor’s threads with PTFE tape; see Figure 12.
2. Slightly loosen the sensor’s bleed screw, using the supplied 5/32-in Allen key.
3. Screw the sensor manually onto the adaptor.
4. Tighten the sensor using General Electric’s Hydran 201TW tube wrench (see
Figure 8) or a strap wrench. Do not use a pipe wrench. Do not use excessive
force when tightening the H201 sensor onto the valve.
Note: If the H201 sensor is installed horizontally, ensure the bleed screw is on top
(at the “12 o’clock” position); see Figure 13.
5. Ensure the bleed screw is in place. Do not tighten it now.
