GNR5C with Threaded Connectors:
•
Mount the top and bottom shut-off valves to the
threaded connectors at the tank using suitable sealing
materials.
•
Insert the 11 x 12 x 5 mm silicon discs into the shut-off
valves.
•
Push the hose clamps for fastening the impact guard
and the sleeve nuts, along with the silicon rings (which
have been snapped into place inside the nuts), over
the standpipe (see figure 2).
•
Insert the standpipe between the shut-off valves
making sure that is square.
•
Check the length of the glass tube! The tube must fit
flush against the silicon discs. Correct if necessary.
•
Push the sleeve nuts up to the shut-off valves and
tighten (46 mm open-end wrench).
Tighten the sleeve nuts.
•
Attach BSM 500 W… bistable switches if used (the
cable gland must always point down).
•
Mount the transparent impact guard (see figure 2).
•
After the vessel has been filled, check all fittings for
leaks!
Maintenance:
If used for its intended purpose, the GNR5C is
maintenance-free.
However, the magnetic float accumulates any magnetic
particles which may be present in the medium over a
period of time. In order to prevent operating errors, the
float should be cleaned to remove magnetic particles at
regular intervals.
In order to clean the float, close both shut-off valves and
empty the medium from the glass tube by opening the
stopcock.
Check the condition of the seals during reassembly and
replace if necessary.
