Note: The actuator must be removed when soldering near
the valve. High heat may cause damage to the
actuator's plastic body/mechanisms. The actuator can
be removed from the valve by loosening the bolt going
through the top of the actuator. When reinstalling the
actuator, do not over tighten. Tighten bolt to 13.5 in-lb.
