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. 1. 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
instructions to determine which port (A or B) should be
connected to the coil bypass.
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
쐃 Use new, properly reamed pipe, free from dents or
corrosion.
쐇 Place the valve on 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.
쐋 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
System 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.
쐃 Disconnect the power supply before connecting the
wiring to prevent electrical shock or equipment
damage.
쐇 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.
쐋 Drain the water from the system.
쐏 Remove the old powerhead from the valve body
(Fig. 10):
a. Place the manual opening lever (normally closed
models only) on the old powerhead in the MAN.
OPEN position (see Fig. 10A).
b. Remove the cover (Fig. 10B).
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. 10C).
e. Remove the O-ring from the top of the valve body.
쐄 Install 40003918 Conversion Kit (Fig. 11):
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.
쐂 Install new powerhead (see Fig. 12):
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 with the manual opening lever
or slot for lever 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.
쐆 Turn on the power.
