The installation shown is only a guide for selecting and installing system components. Contact your Graco distributor
for assistance in planning a system to suit your needs.

The remote filling station pump stalls (dead-heads) when the reservoir is full. If the pump does not stall
(dead-head) there is a leak in the system.

lecting excess fluid that drains during pressure relief
must
be
installed in an easily accessible location between the remote
filling station pump (L) and the Auto-Fill Shut Off (N). This
pressure relief valve is used to relieve pressure in the refilling
line and to reset the Auto-Fill Shut Off.
