The working temperatures are given for an ambient temperature of 20ºC.
The couplings to the tank must be aligned and perpendicular.
Flange bolts should be tightened progressively in a criss-cross sequence to avoid causing
stress.
With threaded connections, they should be tightened progressively and together.
For the LT models (with a glass tube), it is recommended to remove this tube before
mounting the level to the tank.
4 RECEPTION
The series LT level gauges are supplied conveniently packaged for their protection during
transportation and storage, together with their instructions manual for installation and
operation.
All the instruments have been verified in our facilities, ready for installation and operation.
LT level gauges are supplied with the float blocked in its bottom position by means of a stop
introduced into the lower side coupling.
Before mounting on the tank, this stop must be removed.
5 HANDLING
It must be done carefully and without blows.
