7.2 Coaxial multi jet meter with M77x1.5 connection
To mount the Supercal 739 coaxial multi jet with M77x1.5 connection in the EAS
base, the following steps must be respected:
Flush the installation pipes out carefully in compliance with the
DIN/EN standard specification.
Close the shutoff valves before and behind the meter.
Open the drainage valve to reduce the pressure and discharge the
water contained in the pipe between the two shutoff valves.
Consider the direction of flow circulation (EAS base). Check the
flow direction with the arrow figuring on the flow meter.
Remove the blind cover or the old meter from the EAS base using
an installation spanner. Be careful! Water may escape.
Remove the pre-formed gasket then clean the contact surfaces and
the thread.
Place the new o-ring in the EAS base. Make sure that the o-ring is
correctly positioned.
Lubricate the external thread (M77x1.5’) of the metering capsule
with a fine silicone coating.
Remove the protection cap from the metering capsule and position
the capsule in the base. Important! Make sure that the blind hole in
the metering capsule is correctly positioned in the base.
Screw the measuring capsule down firmly by hand, then tighten as
far as the mechanical end stop using a mounting tool.
Install the temperature sensor.
Turn the display into desired position for reading.
Check the waterproof of the meter when it is under pressure.
Seal the measuring capsule and temperature sensors.
