TO PREVENT POTENTIAL INJURY OR DAMAGE TO PROPERTY, READ THIS MANUAL CAREFULLY AND COMPLETELY.
IMPORTANT SAFETY INSTRUCTIONS
Basic safety precautions should always be followed, including the following: Failure to follow instructions
can cause severe injury and/or death.
This is the safety-alert symbol. When you see this symbol on your equipment or in this manual, look
for one of the following signal words and be alert to the potential for personal injury.
WARNING warns about hazards that could cause serious personal injury, death or major property
damage and if ignored presents a potential hazard.
CAUTION warns about hazards that will or can cause minor or moderate personal injury and/or
property damage and if ignored presents a potential hazard. It can also make consumers aware of
actions that are unpredictable and unsafe.
Notice:
A notice indicates special instructions that are important but not related to hazards.
WARNING - Read and follow all instructions in this IOM manual and on the equipment. Failure
to follow instructions can cause severe injury and/or death.
WARNING – Risk of Electric Shock. All electrical wiring MUST be in conformance with applicable
local codes, regulations, and the National Electric Code (NEC). Hazardous voltage can shock, burn,
and cause death or serious property damage. To reduce the risk of electric shock, do NOT use an
extension cord to connect unit to electric supply. Provide a properly located electrical receptacle.
Before working on any electrical equipment, turn off power supply to the equipment.
WARNING – To reduce the risk of electric shock replace damaged wiring immediately.
WARNING – Ground all electrical equipment before connecting to electrical power supply.
Failure to ground all electrical equipment can cause serious or fatal electrical shock hazard.
WARNING – Do NOT ground to a gas supply line.
WARNING – To avoid dangerous or fatal electrical shock, turn OFF power to all electrical
equipment before working on electrical connections.
WARNING – Failure to bond all electrical equipment to system structure will increase risk for
electrocution and could result in injury or death. To reduce the risk of electric shock, see installation
instructions and consult a professional electrician on how to bond all electrical equipment. Also,
contact a licensed electrician for information on local electrical codes for bonding requirements.
CAUTION – Potential pinch point. Equipment connected to or driven by this device may start
unexpectedly and may cause personal injury or entrapment in linkage systems.

ECP SERIES OPERATIONAL CONCEPTS
ECP Series multivoltage electric actuators are motor powered, gear driven actuators for valves, dampers, and
other applications. They can be used with any power supply 24VAC/VDC – 240VAC and feature manual override
handwheels, easily visible position indicators, and a status LED.
All ECP Series actuators rotate CW to CLOSE the OUTPUT shaft out the bottom of the actuator when viewed
from ABOVE. This includes the direction of rotation of the internal cam shaft when viewing with the cover and
indicator removed.
All ECP Series actuators are designed to rotate between 0° and 90° (standard) or between 0° and 180° (option). When
using the manual override system, be sure the yellow position indicator is situated in the correct quadrant before
returning to automatic operation to prevent erratic operation of the actuator under power (see page 6).
Available options for the ECP Series include: Proportional Control with digital feedback, Battery Backup, or Rotation
Options (0°–45°, 0°–90°, 0°–180°). Not all options are available in all combinations for all products in the series.
This IOM is supplied with ECP Series actuators that may have been shipped separately or as an assembly of the
actuator and a Hayward ball or buttery valve. If this actuator was provided as part of the Hayward assembly, a
separate IOM for the valve should be included in your shipment.
Notice: ECP Series actuators are fully assembled, calibrated and tested prior to leaving our factory. In most cases, after
you have mounted the actuator to your device, you should be able to operate the actuator from fully CLOSED (CW) to fully
OPEN (CCW) and back again, and nd that no adjustments are needed. The assembly can be put into service immediately
and should afford the end user years of service without incident. However, should it be necessary to make adjustments to
the end-of-travel positions to overcome any device related issues (i.e. valve shaft incorrectly timed to the drive stem), the
procedures outlined on the page numbers referenced below should be followed to put the assembly into service.

WIRE SIZING CHART
Wire sizing data is provided in the table below to assist in the selection of the proper wire size for Hayward ECP Series
actuators using various wire sizes over distance. Make sure to reference the correct voltage and do not exceed the
indicated length of the wire run for each model.
WARNING – Hayward assumes no responsibility for improper wire selection or improper
wiring. Wire selection and installation is the ultimate responsibility of the
user, and must follow local code requirements.
WARNING – To avoid dangerous or fatal electrical shock, turn OFF power to all
electrical equipment before working on electrical connections.

ACTUATOR HANDLING AND INSTALLATION
SHIPPING AND HANDLING
1. This actuator arrives in the FULLY OPEN (CCW) position. The yellow position
indicator (see photo) shows full CCW (90°) position.
2. Storage: This unit should not be stored outside unless it is powered up and
has proper electrical terminations. When not powered up, it should be stored
in a clean, dry environment at all times.
3. This 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 ECP series actuators have NO mechanical stops to limit rotation.
Do not operate with a rotation greater than 90° unless it has been properly
calibrated to do so.
5. Notice: Protect the actuator from moisture by supplying power to the unit to
keep the internal heater warm at the time of installation.
• For On/Off actuators, in order to keep the 3.5W internal condensate
heater powered up, the actuator needs to receive a continuous OPEN or
CLOSED command at all times.
• For modulating actuators, power on terminals 1 & 2 at all times provides
the required power for the heater.
The actuator is shipped (assembled to
a valve) from the factory in its fully CCW
(90° OPEN) position. The YELLOW stripe
indicates the position of the actuator.
INSTALLATION NOTES
• There are no mechanical stops on the ECP series. Use caution when
operating the manual override. Rotating the drive beyond its intended
rotational angle will cause erratic operation under power. Keep the yellow
stripe between the established rotation angles – in most cases 0° to 90°.
• 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).
• Notice: Use the DIN connectors supplied with the actuator for eld wiring.
• Use supplied DIN connectors and gaskets during installation to protect
the IP67 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 and cable sheath diameter to prevent actuator
failure (see Wire Sizing Chart on page 4 for proper wire sizing).
• Notice: Parallel wiring of multiple on/off actuators is permissible on the
ECP Series.
• ECP Series On/Off actuators utilize two DIN EN 175301-803 connectors
for power and control to simplify eld wiring and testing. ECP Series
Proportional actuators utilize three DIN EN 175301-803 connectors.
The manual override handwheel (ECP3/5
shown), allows a user to position the
valve or damper with or without power.
The arrow molded in the handwheel
cover shows the direction you must turn
the handwheel to close the actuator
and attached device (ECP8 is reversed).
DIN Connectors
Removable DIN EN 175301-803
connectors facilitate ease of eld
wiring and testing.
WARNING – To avoid dangerous or fatal electrical shock, turn OFF power to all
electrical equipment before working on electrical connections.
