1. Position on arrival:
•
A separate actuator arrives in the FULLY CLOSED (CW) position. The
red/green position indicator (see illustration) shows RED.
•
A 2 way ball valve assembly arrives in the FULLY OPEN (CCW) position
and the position indicator shows GREEN.
•
A 2 way butterfl y valve assembly arrives nearly CLOSED (5°) position
and the position indicator shows mostly RED.
2. Storage: This unit should not be stored outside unless it is powered up and
has proper conduit terminations. When not powered up, it should be stored
in a clean, dry environment at all times.
3. This quarter-turn actuator has been factory tested and calibrated to operate
between 0° and 90°. Most products will not require recalibration of these
settings. If any travel adjustment is necessary, please refer to the Adjusting
CW/CCW End of Travel section for instructions.
4. Notice:
The Series actuators have mechanical stops which limit
rotation. Do not attempt to operate with a rotation greater than 95°.
5. Notice:
Protect the actuator from moisture by installing it with water tight
EMT fi ttings and proper conduit drainage. Supply power to the unit to keep
the internal heater warm at the time of installation.
SHIPPING AND HANDLING
INSTALLATION NOTES
The actuator has a red and green position
indicator. RED color in the indicator
window means the actuator is fully
CW, while GREEN means it is fully CCW.
The manual override handwheel
allows a user to position the valve or
damper with or without power. Turn
the handwheel CW to make the output
drive move CW (when viewed from
above). Turning the handwheel CCW
makes the output drive turn CCW.
WARNING –
To avoid dangerous or fatal electrical shock,
turn OFF power to all electrical equipment
before working on electrical connections.
CAUTION –
Please follow the following guidelines for proper installation.
•
These actuators are designed to be used between a horizontal and
upright position. Do NOT mount the assembly with the actuator top
below a horizontal position (i.e. upside down).
•
When installing conduit, use proper techniques for entry into the actuator.
Use drip loops to prevent conduit condensate from entering the actuator.
•
Mechanical travel stops are factory calibrated for 90 degree operation.
These stops are NOT designed to adjust mechanical rotation by more
than +/- 3 degrees, they are for positioning the handwheel only.
•
Both EMT conduit ports MUST use proper equipment to protect the
NEMA 4X integrity of the housing.
•
The internal heater is to be used in ALL applications.
•
Do NOT install the actuator outdoors or in humid environments unless it
is powered up and the heater is functioning.
•
Use proper wire size to prevent actuator failure (see Wire Sizing Chart for
proper wire sizing).
•
All terminals accept 12-18AWG solid/stranded wire.
•
Notice:
Do NOT parallel wire multiple on/off actuators together without
utilizing isolation relays. If this is your intention, please contact
Flo-Tite
for
a multiple actuator parallel wiring diagram.
