Great Plains 1700TT Dual Valve - Manual (Page 4)

9) Use the 42” hose (21) that you removed from the rear of the machine to connect the
elbow (14) at the rear of the new valve (3) to the tee (17) that you inserted into the
return line at the rear of the old valve (2).
10) This should complete the installation. Double check the hose routing with the
schematic and then tighten all fittings and hoses. After tightening, slowly try to fold
the unit while watching for leaks. If no leaks occur, fold and unfold machine several
times to purge the air from the system. You are now ready to set the down pressure.
Refer to the instructional page for the proper procedure for setting the down pressure
with multiple valves.
