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 • Tools (not provided):

– Appropriate wrenches for stem extensions, lock nuts, packing nuts, and brackets – Appropriate screwdriver for actuator mounting screws – TOOL-37, 1-5/8" open-ended wrench with a ma

• Training: Installer must be a qualified, experienced technician

Caution:

• Install the unit in accordance with the National Electric Code Article 500 and all

applicable local codes.

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

• Install all two-way valves so that they close against the flow. An arrow on the valve body

or a tag indicates the proper flow direction.

• Always install three-way mixing valves with two inlets and one outlet.

• Always install three-way diverting valves with one inlet and two outlets.

• The actuators can be mounted in any position above the centerline of the valve body.

For steam applications where the ambient temperature approaches the limit of the actuator, the valve stem should be mounted 45° from vertical. When selecting a location, allow sufficient room for accessories and for service of the product.
