to prevent injuries from scalding always drain
system before unlatching valve assembly from
body.
Be sure that bayonet lock securely latches mounting
plate to body. Failure to do so could allow valve head
to separate from body and result in scalding injuries
and/or water damage.
3. Be sure that any excess solder, flux, or other foreign matter
is thoroughly removed from the valve bore.
4. With valve body mounted in the line, remove the head
assembly from the carton, and carefully wipe stem with a soft
cloth to remove any dust or grit.
5. The valve head may now be assembled to the valve body.
With valve head positioned as shown in figure 5, insert valve
stem into valve bore, push downward, and turn valve head
until it locks to valve body.
6. Support piping with a pipe hanger on each side of valve. The
valve is now ready to be wired.
All wiring should be done according to local and national electrical codes
Do not attempt to wire two or more zone valves in
parallel to operate from a single thermostat. (If valves
are wired in parallel, the motors may run continuously,
due to feedback between the motor holding circuits.)
For best connections, use #18 Thermostat wire. #16 will also
work satisfactorily.
Make connections to screw terminals according to wiring dia-
gram.
NOTE: To check motor operation without thermostat con-
nected, jumper 2 and 4 to open valve; remove jumper
to close valve.
If the boiler manufacturer recommends a wiring diagram, follow
his instructions. If none are available, the following diagrams
show suggested circuits for Type 1361 Water Valves in conjunc-
tion with two-wire thermostat (.2 Amp. anticipator) and other
related controls.
A 40 VA transformer will handle up to four (4) water valves. A
20 VA transformer will handle a maximum of two (2) 1361 series
valves.
