WARNING!
Always disconnect and lockout all electrical power and pneumatic
(i.e. compressed air) sources prior to servicing or cleaning any
HydReclaim product, including all OS/OA Series blending
systems. Failure to do so may result in serious injury or death.
WARNING!
Air line reversal. If air lines are removed from the switch itself, be
sure they are re-installed on the proper parts. If they are reversed,
you will hear air leaking out of the switch and the safety system
will be bypassed.
