INSTALLATION
When Installing This Product...
1.
Read these instructions carefully. Failure to follow
them could damage the product or cause a
hazardous condition.
2.
Check the ratings given in the instructions and on
the product to make sure the product is suitable for
your application.
3.
Installer must be a trained, experienced service
technician.
4.
Always conduct a thorough checkout when
installation is completed.
5.
While not necessary to remove the actuator from the
body, it can be removed for ease of installation. The
actuator can be installed in any of the four
orientations to suit the most convenient wiring
direction. Actuator latching mechanism works only
when the lengths of the actuator and the valve body
are parallel to each other.
6.
An extra 1” (25 mm) head clearance is required to
remove the actuator.
CAUTION
Disconnect power supply before connecting
wiring to prevent electrical shock and equipment
damage.
Never jumper the valve coil terminals, even
temporarily. This may damage the thermostat.
PLUMBING
The valve may be plumbed in any angle, including vertical
piping, but preferably not with the actuator below the
horizontal level of valve body. Make sure there is enough
room around the actuator for servicing or replacement.
For use in diverting applications, the valve is installed with
the flow water entering through bottom port AB, and
diverting through end ports A or B. In mixing applications
the valve is installed with inlet to A or B and outlet through
AB.
Mount the valve directly in the tube or pipe. Do not grip the
actuator while making and tightening up plumbing
connections. Either hold valve body in your hand or attach
adjustable spanner (38 mm or 1-1/2") across the
hexagonal or flat faces on the valve body. (Fig. 4).

COMPRESSION MODELS
For compression fitted models, tighten the compression
nuts enough to make a watertight seal.
TAKE CARE NOT TO OVER TIGHTEN.
Maximum torque limit is 45 Nm (33 ft-lb) for the 22 mm
compression fitting, and 65 Nm (48 ft-lb) for the 28 mm
compression fitting.
SWEAT MODELS
On sweat fitted valves, the cartridge is shipped loose to
avoid being damaged during the solder operation.
1.
Remove valve actuator from body and solder the
connecting pipes in accordance with normal
soldering practices.
2.
After soldering and valve has cooled, remove
cartridge assembly from plastic bag, insert into the
valve body and tighten down with enclosed wrench
(part# 40007029-002) until it bottoms out.
DO NOT OVER TIGHTEN (maximum torque is
4.5 Nm [40 in-lb]). The top surface of the cartridge
will be flush with the top edge of the body casting.
3.
Replace valve actuator.
