fitting (5). Thread the 90°fitting (5) into the drain hole
on the underside of the recovery tank.
(Refer to FIG. 2)
13.Apply ’No more leaks’ to the end of the 90°fitting (6).
Thread the 90°fitting (6) into the end of the solution
pump (4). Thread the 90°fitting (5) into the open end
of 90°fitting (6), using ’No more leaks’ to seal the
fittings. Thread the straight fitting (7) into the top side
of the solution pump (4), using ’No more leaks to seal
the connection. Connect one end of the 8” braided
hose (10) to the 90°fitting (5) with a hose clamp (11).
(Refer to FIG. 2)
14.Mount the solution pump (4) to the rear of the

tank with a hose clamp (11). (Refer to FIG. 2)
16.Connect one end of the 36” long braided hose (12) to
the straight fitting (7) in the top of the solution pump
(4) with a hose clamp (11). (Refer to FIG. 2)
17.Disassemble the straight fittings securing the mesh
filter in the bottom of the solution tank. Insert the 45°
plastic fitting (13) between the straight fittings, so the
mesh filter will sit level when the solution tank is
remounted. (Refer to FIG. 2)
18.Remount the solution tank back onto the machine
frame with set aside mounting hardware. (Check that
the 0.62 in Æhose is routed through the frame
opening).
