INSTALLATION
Before installation, check nameplates to verify actuator and
valve selected are appropriate for the application.
IMPORTANT: After actuator installation, test all functions
and check out complete system before putting actuator/valve
into service.
Positioning/Mounting
Follow the V710 Series Gas valve and/or damper
manufacturer's instructions when installing the Hydramotorr.
1. AH2D actuators can be installed to operate in any
position.
2. Position the actuator to operate the valve (and damper if
appropriate), and secure with the two mounting set screws
(Figure 2). Torque set screws to 80 ± 5 in-lbs
[9,0 ± 0,5 Nm] using a 5/32I hex key wrench.
3. For damper applications requiring the damper arm to
return upon power failure, the optional return spring and
spring plug (kit 440006) must be installed on the damper
arm. Connect linkage so that damper returns to the
desired position.
Wiring
WARNING: Electrical hazard. To prevent the
possibility of death, serious injury or property
damage, open circuit before inspection, service or
disassembly. Reassemble before operating.
Wiring must comply with local codes and the National
Electrical Code. Limit controls must conform to actuator
rating (voltage, amperage, hertz). Wire limit controls to the hot
side of power supply.
1. Remove six screws and electrical cover.
2. Route wiring through one of the conduit knockout
openings. Install appropriate electrical fittings.
3. Connect the power wiring to terminals N (neutral) and L1
(hot). A green grounding screw with a cup washer is
provided beside the terminal strip for grounding.
(Figure 3).
4. Torque terminal screws to 8-12 in-lbs [0,9-1,3 Nm].
5. Connect auxiliary or valve overtravel proof-of-closure
switch wiring to the common and normally open or
normally closed switch terminals (Figure 3).
6. Reinstall electrical cover on actuator housing.
7. Operate system through five cycles to verify proper
operation.

CAUTION: Overtravel Proof-of-closure switch
must only be used with V710 Series Gas Valves
having an overtravel seal (V22 or V25 Suffix in catalog
number).
Overtravel Proof-of-Closure Switch
The optional valve overtravel proof-of-closure switch is set at
the factory to provide both a mechanical and electrical means
of proving valve closed position interlock to the primary
control. This switch is not to be field adjusted.
