FASTENING THE HYDRAN 201TI'S COVER

Replace the H201Ti's aluminum cover as soon as the installation is completed.
1. Ensure the rubber washer is present on the central post.
2. Slide the cover over the H201Ti.
3. Fasten the cover by tightening the knob. The breathing membrane must be facing
down (at the "6 o'clock" position) if the H201Ti is installed horizontally.
If connected to a Hydran 201Ci Controller, the H201Ti will later be used to test this
Controller.

COMMISSIONING

1. Wait at least two hours for the Hydran 201Ti to stabilize. The Hydran 201Ci
Controller(s) can be installed during this time.
2. Verify the H201Ti's accuracy by comparing its readings with a recent dissolved gas
analysis (DGA).
3. If necessary and with the permission of the user, set the alarm set points again, this
time according to the current level of dissolved gases in oil. See Section 10.4.1 on
page 10-9.
The installation of the H201Ti is now completed. If properly installed and maintained, the
H201Ti provides many years of trouble-free service.
