MOUNTING

The valve can be mounted in any position on a vertical line. If the valve is mounted horizontally; the powerhead must be even with or above the center line of the piping. Make sure that enough room is provided above the powerhead to remove the cover for servicing.

Fig. 2. Mounting positions.

Mount the valve directly in the tube or pipe. Make sure that the flow through the valve is in the direction indicated by the arrow stamped on the valve body.

On diverting valves, the three fittings or ports are labeled on the bottom of the valve body casting. See Fig. 3. Port AB is the inlet port and is open at all times. Port A is closed when the valve is de-energized; port B is open

when the valve is de-energized. Refer to the equipment manufacturer’s instructions to determine which port (A or B) should be connected to the coil bypass.

Fig. 3. Inlet and outlet ports on straight-through and diverting valves.

FLARE FITTING MODELS

Use new, properly reamed pipe, free from chips. The valve body is threaded for standard 5/8 in. OD copper, 45 degree SAE flare fitting nuts. These nuts are not furnished with the valve and must be obtained separately.

SWEAT COPPER MODELS

1.Use new, properly reamed pipe, free from dents or corrosion.

2.Place the valve onto the pipe. Set the manual opening lever to MAN. OPEN position before applying heat. This protects the plug inside the valve by removing it from the seat.

3.IMPORTANT: Take care not to burn the plastic portion of the composite adapter plate when soldering.

4.Sweat the joints, keeping the outer surface free from solder. DO NOT use silver solder because of the high melting temperature required.

To Install Replacement Powerhead

SYSTEMS WITH OLD STYLE VALVE BODIES (SERIES 1-5)

To install a replacement powerhead in a system with an old style body (series 1-5), the valve body must be converted to accept the new powerhead using Part No. 40003918 Conversion Kit. The kit includes a metal plate with a driveshaft and rubber plug, O-ring, and four screws.

IMPORTANT

Converting the valve body for use with the new powerhead does not require removal of the valve body from the pipeline. However, it is necessary to drain the water from the system before beginning the conversion.

A

V4043, V4044 VALVES; V8043, V8044 ZONE VALVES

1.Disconnect the power supply before connecting the wiring to prevent electrical shock or equipment damage.

2.Disconnect the leadwires to the powerhead at the terminal block or conduit connection. Remove the conduit or cable connector if fitted. Label each wire for rewiring later.

3.Drain the water from the system.

4.Remove the old powerhead from the valve body (Fig. 4)

a.Place the manual opening lever (normally closed models only) on the old powerhead in the MAN. OPEN position (see Fig. 4A).

b.Remove the cover (Fig. 4B).

c.With the cover off, remove the four screws securing the powerhead to the valve body.

d.Lift the powerhead off the valve body (Fig. 4C).

e.Remove the O-ring from the top of the valve body.

5.Install 40003918 Conversion Kit (Fig. 5)

a.Insert the new O-ring in the valve body.

b.Place metal plate with the rubber plug on top of the valve body. Make sure the guide pins on the underside of the metal plate fit into the recesses on the valve body.

c.Secure the metal plate to the valve body with the four screws (two sets) provided. One set of screws has heads with recessed threads to

insert screws for mounting the new powerhead; insert this set into the larger screw openings. The other set has domed heads; insert this set into the smaller screw openings. Each set of screws must be inserted in opposite corners of the metal plate so the screws sit flat on the plate. Make sure the guide pins on the plate fit into the recesses on the valve body.

a. Place the manual opening lever (normally closed models only) on the new powerhead in the MAN. OPEN position.

b. Fit the powerhead onto the valve body, ensuring that the shaft seats correctly. The powerhead should be aligned so that the manual opening lever or slot for lever is at the port A end of the valve body.

c.Secure the powerhead to the valve body with the two screws provided.

d.If fitted, reconnect the conduit or cable. Reconnect the leadwires at the powerhead.

e.Replace the powerhead cover.

7.Turn on power.

SYSTEMS WITH NEW STYLE VALVE BODIES (SERIES 6)

IMPORTANT

On a new style valve body that has been converted to accept the new powerhead, it is not necessary to drain the system if the valve body remains in the pipeline.

1.Disconnect the power supply before connecting the wiring to prevent electrical shock or equipment damage.

2.Disconnect the leadwires to the powerhead at the terminal block or conduit connection. Remove the conduit or cable connector, if fitted. Label each wire for rewiring later.

3.Remove the old powerhead (see Fig. 7):

a.Place the manual opening lever (normally closed models only) on the old powerhead in the MAN. OPEN position (Fig. 7A).

b.Remove the screw securing the cover to the powerhead (Fig. 7B).

c.Lift off the cover from the powerhead.

d.Remove the two screws securing the powerhead to the valve body (Fig. 6).

e.Lift the powerhead off the valve body.
