User guide

When installing flared tubing to the
flow controller, the flared tube is
pushed over the valve’s fitting until
the fitting reaches the smaller tube
diameter. The amount of torque
required to tighten the nut is depen-
dent upon the size of the fitting.
Care should be taken when installing
the flow controller to avoid fluid
leaks. Do not use excessive torque or
subject the unit to high heat during
installation. The unit and base
bracket assembly must be mounted
to a solid surface to ensure stability.
Verify the body and the electrical
cable are free from mechanical stress
from the surrounding equipment.
Electrical Connections
Connect cable to flow controller
The cable mounting receptacles are
physically “keyed”, making it impos-
sible to insert the connector improp-
erly. Press it into the mounting
receptacle and rotate the outer
coupling ring to lock the connector
in place. To remove the connector,
rotate the coupling ring in the
opposite direction.
Power Cable
Cable materials are constructed
with 22 AWG wire and a PVC jacket.
The connector is a 4-pin, 12 mm,
male type.
