3. It is recommended to mount the Hydran 201Ti horizontally. Ensure the bleed
screw is on top (at the “12 o’clock” position); see Figure 13 below.

4. If no horizontal valve is available, a vertical installation may be acceptable;
contact General Electric Customer Service (contact information can be found
at the bottom of page 2). If the H201Ti is installed vertically, note the
following points:
• The sensor’s threaded extremity must be oriented upward.
•
The oil temperature at this location must always be below 30°C (86°F).
• It is recommended to set the temperature set point (Temp SetPoint
parameter in the Temperature submenu) of the H201 sensor to 45°C
(113°F).
Do not use a 90° elbow to convert a vertical installation to a
horizontal installation.
5. Always mount the H201 sensor on a full-bore gate or ball valve where there is
sufficient convective oil flow. The H201Ti is installed on a valve with a 1.5-in
nominal diameter (NPT female threads). If necessary, use a reducing bushing.
The body of the valve must be grounded
Note: To ensure sufficient oil flow past the sensor’s membrane, the nominal
diameter of the valve should never be less than 25 mm (1 in). Furthermore, to
ensure optimum performance of the H201Ti, the diameter should not exceed
76 mm (3 in).
