Dampers
The actuator is not position sensitive. It can be mounted in any position in an NEMA Type 1 location.
Valves
Allow 3" (76 mm) of clearance above the actuator valve assembly for the removal and reattachment of the actuator to the installed
valve.
1. Install all two-way valves so that they close against the flow. An arrow on the valve body or tag indicates proper flow direction.
2. Always install three-way mixing valves with two inlets and one outlet.
3. Always install three-way diverting valves with one inlet and two outlets.
Caution: For steam applications only, mount the actuator above the valve body at 45° from vertical.
4. Actuators can be mounted in any upright position above the centerline of the valve body.
Wiring Requirements
Control Leads
The control leads may be connected to a Class 2 circuit if routed separately from Class 1 circuit wiring. Refer to Figure-8.
Refer to Table-4 for the maximum wire run of the control leads.
Caution:
• Use three-conductor, twisted, shielded wire when it becomes necessary to install the control leads in the same conduit with
power wiring or when RFI/EMI generating devices are near.
• Do not connect the shield or conduit to earth ground.
Table-4 Control Wiring Data.
Power Leads
The low voltage (24 Vac) power leads may be connected to a Class 2 circuit if routed separately from Class 1 circuit wiring. Refer
to Figure-8. Line voltage power leads must be connected to a Class 1 circuit.
Refer to Table-5 for maximum length of run for given wire size(s). To determine the allowable maximum power lead run for
multiple actuator wiring, divide the maximum run shown in Table-5 by the number of actuators on the run.
