12 It is strongly recommended to use lifting straps to lift
the actuator/valve assembly.
13 If an actuator/valve assembly should be lifted, it is
strongly recommended to connect the lifting straps
in such way that the actuator and valve is sup-
ported.
1.4 WARNINGS.
1 Do not attempt to install or repair any electric device
without shutting off incoming power.
2 Do not operate valve without rst setting limit
switches and checking direction of motor rotation.
3 Release torque before disassembling gear train
components or the actuator from the valve.
4 Do not adjust torque switch settings. (these are fac-
tory set and need no adjustment)
5 Do not use a cheater or extension bar on the hand
wheel. (This could result in damage to the valve
assembly or cause physical injury)
6 Do not alternately start and stop motor to seat
or un-seat a valve. If properly sized, the running
torque of the actuator should seat the valve in
normal operation.
