4.4 instaLLatiOn Of the f02 unit OntO
a VaLVe
Move the valve to the completely open position.
Manually bring the f02 to the completely open
position (verify the local mechanical indicator)
and check the rotation direction of actuator
and valve. the actuator should be mounted
for counter-clockwise rotation to open and
clockwise to close.
the f02 unit can be installed onto the valve in
two different ways:
direct mounting:
insert the valve shaft into the actuator bottom
flange, taking care to correctly connect the
insert. fix the screws on the valve flange to the
actuator coupling block.
Bracket mounting:
install the bracket and the adapter onto the
valve; then insert the valve shaft into the
actuator bottom flange, taking care to correctly
connect the insert.
fix the screws between the bracket and the
valve flange and the actuator coupling block.
Warning
Never lift the valve/actuator assembly without
securing slings to both the valve and the actuator.
Never use the handwheel to lift the actuator.
Warning
Do not manually operate the actuator with devices
other than the handwheel. Using cheater bars,
wheel wrenches, pipe wrenches, or other such
devices on the actuator handwheel may cause
serious personal injury and/or damage to the
actuator or valve.

Manual operation.
4.5 ManuaL OperatiOn
f02 electric actuators are supplied with a
handwheel for manual override as standard, to
operate the actuator in case of power supply
failure or during setting.
the handwheel is always engaged. for safe
operation, the handwheel does not rotate
during electric operation.
turn the handwheel clockwise to close and
counter-clockwise to open.
During manual operation, check the actuator
manoeuver on the local mechanical indicator.
