INSTALLATION Inspection Inspect the package for damage. If damaged, notify the appropriate carrier immediately.

If undamaged, open the package and inspect the device for obvious damage. Return damaged products.

Requirements • Job wiring diagrams.

• Tools (not provided):

– Digital Vo lt-ohm Meter (DVM). – Appropriate drill and drill bit for mounting screws. – Appropriate screw drivers and wrenches. – TOOL-12, Wrench for adjustment of auxiliary switch. – TOOL-19, Spring compression tool for AV-600. – TOOL-37, 1-5/8" (41 mm) open-ended wrench.

• Training: Installer must be a qualified, experienced technician.

Warning:

• Disconnect power supply before installation to prevent electrical shock and equipment

damage.

• Make all connections in accordance with the wiring diagram and in accordance with

national and local electrical codes. Use copper conductors only.

Caution:

• Static charges produce voltages high enough to damage the electronic components.

Follow static electricity precautions when installing or servicing the device(s). Discharge any static electricity you may have accumulated by using wrist straps, or by touching a known, securely grounded object.

• Do not exceed the ratings of the device(s).

• Do not apply power to the unit unless the damper linkage and/or the valve assembly

have been installed.

• Avoid locations where excessive moisture, corrosive fumes, or vibration is present.

• Do not install insulation on any part of the actuator.

Mounting Do not twist or exert any force on the actuator housing during installation. Either turn the

base by hand or, if necessary , use a 1-5/8" (41 mm) open-ended wrench (TOOL-37) on the flats provided on the actuator base or the valve body mounting nut. Refer to

Figure-2 Housing and Base Location.

Dampers

The actuator is not position sensitive. It can be mounted in any position in a 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 o n 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.

Figure-2.

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 Power Leads

The low voltage (24 Va c) power leads may be connected to a Class 2 circuit if routed separately from Class 1 circuit wiring. The line voltage (120 and 240 Vac) leads must be connected to a Class 1 circuit. Refer to

Refer to T able-4 for the maximum length of run for the power leads, for the given wire size(s). T o determine the allowable maximum power lead run when wiring multiple actuators, divide the maximum run shown in for further details.
