harmful interference if not installed and used in accordance with the instructions. Even
when instructions are followed, there is no guarantee that interference will not occur in a
particular setting—Which can be determined by turning the equipment off and on—the user
is encouraged to try to correct the interference by one or more of the following measures:
•
Reorient or relocate the receiving antenna.
•
Increase the separation between the equipment and receiver.
•
Connect the equipment to an outlet on a circuit different from that to which the receiver
is connected.
•
Consult the dealer or an experienced radio/television technician for help.

Note: This Class B digital apparatus meets all requirements of the Canadian Interference-
Causing Equipment Regulations.
Cet appareil numerique de la classe B respecte toutes les exigences du Reglement sur le
material broilleur du Canada.
European Standard EN 55022
Warning: This is a Class B digital (European Classification) product. In a domestic
environment this product may cause radio interference in which case the user may be
required to take adequate measures.
Caution: Avoid locations where excessive moisture, corrosive fumes, vibration, or
explosive vapors are present.
•
Mount the linear actuator directly on the valve in locations that clear the maximum
dimensions of the actuator case (see Figure-12).
•
Ensure that the valve body is installed correctly. The arrow must point in the direction
of flow. With three-way valves observe stem position (stem up or stem down) for proper
flow characteristics. See Table 3.
•
It is preferable that the actuator is mounted above the valve body. This will minimize the
risk of damage to the actuator in the event of condensation or a valve leak. Refer to
Figure-10.
Changing Control Function (proportional units only)
These actuators are equipped with a jumper to control the function of the signal as received.
See Figure-9. Factory setting is for direct acting. Remove cover to change jumper setting.
