* CONTACT HWH WHEN REPLACING ONE OF THESE POWER UNITS ON A 610 PUMP/MANIFOLD. IN MIDYEAR 1992 THE PRESSURE AND RETURN PORTS ON TOP OF THE PUMPS WERE CHANGED FROM 0.438" DIA. HOLES TO 1/4" NPT (.54" DIA.) THREADED HOLES. THUS THE O-RING SPOT FACES ON THE BOTTOM OF THE MANIFOLD WERE CHANGED FROM 5/8" DIA. TO 11/16" DIA. TO ALLOW LARGER O-RINGS TO COVER THE LARGER PUMP PORT. REPLACEMENT PUMPS HAVE THE 1/4" NPT PORTS THUS THE MANIFOLD MUST BE CHECKED TO DETERMINE IF IT HAS THE 11/16" DIA. SPOT FACES. IF THE MANIFOLD DOES NOT HAVE THE 11/16" DIA. SPOT FACES IT MUST BE RETURNED TO HWH FOR RE-SPOT FACING.
