INSTALLATION

Inspection

Inspect the package for damage. If package is 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)

— Wrench 1 to 1-5/8" (if threaded valve)

— Soldering equipment (if sweat fit) or flare

• Training: Installer must be a qualified, experienced technician

• Other accessories as appropriate

Precautions

General

T W A R N I N G

• Electrical shock hazard! Disconnect power before installation to

prevent electrical shock or equipment damage.

• Make all connections in accordance with the electrical wiring

diagram and in accordance with national and local electrical

codes. Use copper conductors only.

• All conductors shall be provided with insulation rated for the

highest voltage motor and end switch circuits.

T C A U T I O N

• Avoid locations where excessive moisture, corrosive fumes,

explosive vapors, or vibration are present.

• Avoid electrical noise interference. Do not install near large

conductors, electrical machinery, or welding equipment.

• When making lead connections within the actuator, use caution

not to put leads or connectors below the motor.

Mounting

The valves can be mounted in horizontal or vertical piping. When

installed in horizontal piping, the actuator must be above the valve

body. Refer to Figure-5. When installed in horizontal piping the

actuator can be tilted left or right but it must not be tilted below 85°

from vertical.

N O T E

• Make certain there is no overhead water source that may drip

onto valve actuator.

• In normal service, some condensation may occur on or around

the valve. A drip pan may be necessary or the valve body may

be insulated.

Piping

These valves must be piped so the paddle closes against the

direction of flow. Flow is from B to A. Refer to Figure-6a to

Figure-6f. When installing the actuator to a normally closed valve,

the actuator must be placed in the manually open position by using

the manual operating lever. The first time the valve is operated

electrically, the manual operating lever of the actuator will transfer

to the automatic position. The manual operating lever can be used

to allow flushing of the system after installation. The valves are

designed for application in closed hydronic heating and cooling

systems. High levels of dissolved oxygen and chlorine found in

open systems may attack the valve materials and result in

premature failure. Install over a drip pan if condensation in chilled

water applications occurs.

T C A U T I O N

Use in systems which have substantial make-up water (open

systems) is not recommended. Follow proper water treatment

practices and system procedures. Refer to document F-26080-1

for Water and Steam EN205 Guidelines.

N O T E

• Three-way valves always require a normally closed actuator.

• Three-way valves are always closed at the B port when no

power is applied to the motor.

• On power-up the valve closes to A port on three-way valves.

• Orient the three-way valve body as needed for normally open or

normally closed flow through coil.
