1.3 Do
1 Keep motor compartment clean and dry.
2 When applicable connect the compartment heater.
3 Check unit wiring and ensure it coincides with the
proper wiring diagram.
4 Power supply should be free from excessive
voltage transients (spikes).
5 Control lines should be shielded properly.
6 CAUTION: Shut off incoming power before
installing or repairing any electrical device.
7 Check motor nameplate to be certain that the
actuator voltage is the same as your incoming
voltage.
8 Schedule a periodic maintenance check of all El-
O-Matic actuators to prolong life and ensure
proper performance (we suggest check for correct
opening and closing once a month).
9 Set open and close limit switches manually, in
accordance with instructions.
10 Be sure and lubricate unit during reassembly. (see
LUBRICATION)
11 Check limit switch setting prior to motor operation
if the actuator has been repaired or disassembled.
1.4 Don't
1 CAUTION: Do not attempt to install or repair any
electric device without shutting off incoming power.
2 Do not operate valve without first 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
factory set and need no adjustment)
5 Do not use a cheater or extension bar on the
handwheel. (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. f properly sized, the running
torque of the actuator should seat the valve in
normal operation.
