(1) - Filling the installation:
Remove the plugs from the side
valves and connect the hose unions.
Close the ball valve and open the side
filling valve and draining valve.
Directions for the use of the flowmeter to fill the installation:
(2) - Starting the installtion working:
Open the ball valve and close the side
filling and draining valves. Remove the
hose unions and screw again the plugs.
to avoid any casual opening of the side
valves, it is better to stop the levers in
the close position, as shown here aside.
(3) - Regulate the flow rate using the
regulation rod until the right flow rate
is shown.
N.B. The flow rate is shwon taking
as reference the lower edge of the
sliding cursor. (see picture).
The vent air is a device that divides continually the air
that can be in circulation together with the fluid. The
air goes to the upper part of the vent air and it can be
eliminated through the special drain while the installation
is working. unscrew of 360º the knurled metal ring lock.
This operation ahs to be done at intervals.
Danger of burns - To avoid any leakage of the
fluid, taking into consideration the very high working
temperature, we recommend to fasten a pipe to the
end of the drain
