Operation
3.
Install a condensate trap if Unitel is mounted below the max.
liquid level in the tank or in a place where condensate may col-
lect.
4.
Push connector onto capillary tube.
5.
Insert capillary line into connector and push in to the stop.
6.
Tighten pressure screw gently.
7.
Connect standpipe to capillary line, using for instance a hose
connector.
Unitel provides a semi-permanent indication. The built-in pump clos-
es off the measuring line when it reaches the end of its travel, the
pointer stays temporarily at its last reading and then drops back very
slowly. As a result of this the gauge mechanism is protected by an
air cushion.
Do not operate gauge during a tank filling operation as the gauge will
not give a stable reading.
1.
Pull out pump plunger to its stop and then release.
2.
Repeat this process until the indication is stable.
3.
Read tank contents on the dial of the gauge.
If the capillary measuring line has been installed absolutely airtight
the pointer of the gauge will continue to show the last reading over a
long period of time. In order to obtain an accurate up-to-date reading
we recommend that you operate the pump everytime before a read-
ing is taken.
The reference pointer can be adjusted manually. When set to the
latest reading it serves for consumption control purposes.
