IS-S75/S105
Wiring Instructions
!
CAUTION:
An interruption of 10 milliseconds or greater to
the power supplied to the solenoid of a solenoid operated
valve may cause the valve to shift. Provision must be
made to prevent power interruption of this duration to
avoid unintended, potentially hazardous, consequences.
NOTE:
In addition to the following instructions, follow all requirements
for local and national electrical codes.
Electrical Connection
Valves with 3-Pin male terminals should have power connected to
the parallel terminals. Ground should be connected to the
perpendicular terminal.
Override Operation
The flush non-locking manual override is located on the body of
the solenoid pilot. To operate the override, place a small screwdriver
in the slot of the override and turn approximately 45° in either
direction until the solenoid pilot actuates. The solenoid pilot will
remain actuated until the override is released. When released, the
solenoid pilot de-actuates.
Solenoid Replacement
To replace the solenoid,
remove the solenoid nut and
pull solenoid off and replace
with the correct voltage
solenoid. Replace solenoid
nut and tighten finger tight.
See Figure 1.
