■
Use only new and flawless sealing
material and check the seal face
for damage.
■
Install the new flow sensor accor-
ding to the correct flow direction
and installation position.
■
Turn heat computer to desired
reading position.
Information: The best measuring
results can be achieved by moun-
ting with horizontal diallevel. Combi-
devices are, for example, used in
tight installation points without room
for the calculator on the flow sensor
or when the calculator is difficult to
read. Therefore the device still re-
mains easy to read enabling opti-
mum use of the space available for
installation of the flow meter.
Installation of the temperature
sensors
■
The installation of the tempera-
ture sensors should be preferably
symmetrical and direct installati-
on.
■
Do not remove the return sensor
if already mounted on the VMU.
This is also valid for all the safety
seals which are mounted on the
device as a standard.
