b. Remove the hose inlet from the water pump
system bypass outlet (Q) and place a hose
clean-out ball within the hose inlet. The ball
must be wetted down before inserting. If using a
1 in. whip hose, begin with the smallest
clean-out ball.
c. Reattach the hose to the water pump system
bypass outlet (Q), open the ball valve, and
press the water pump button (Z) to resume
flushing the hose.
d. The clean-out ball will be pushed out of the
hose after several minutes. Once the ball is
pushed through the hose, press the water pump
button (Z).
e. If using a 1 in. whip hose, remove the hose and
transition fitting and repeat the process using
the large clean-out ball on the remaining hoses.
Once the ball is pushed out, stop the water
pump and reattach the transition fitting and whip
hose.
f.
Upon completion, close the ball valve, remove
the hose inlet from the water pump system
bypass outlet (Q), and attach the hose inlet to
the pump outlet (L).
10. Remove the Geka fitting cap (GF) from the lower
port.
11. Press the water pump button (Z), then hold the
water prime button (Y) for several seconds. Once
water flows from the lower port, release the water
prime button (Y).
NOTE: If water does not fill the mixing chamber, see
Startup After Extended Storage, page 18, or con-
tact Graco Technical Support.

12. Add dish soap or a slicking agent to the water
through the lower port and replace the Geka fitting
cap (GF).
NOTE: When priming with water, add dish soap or a
slicking agent to help lubricate the pump. Priming
with water only may cause excessive pump friction,
Q
producing a high pitch noise and premature pump
wear.
13. Turn the speed selector knob (V) to speed 1 and
press the START button (U). If the pump does not
turn within five seconds, press the STOP button (U)
and follow the next step. If the pump turns, skip step
14 and proceed onto step 15.
NOTE: Do not run the rotor/stator pump with water
for more than five minutes at a time or premature
pump wear may occur.
14. If the pump did not turn within five seconds, perform
the steps below:
a. Press the START button (U) and quickly turn
the pump direction switch (W) between forward
and reverse.
NOTE: The pump direction switch (W) is nor-
mally in the FWD position. The switch must be
held in the REV position to reverse the pump
direction. The switch will return to the FWD
position when it is released.
NOTE: If the pump has not been broken free
after five seconds, press the STOP button (U)
or the motor control could encounter an over-
load error. After multiple attempts to free the
pump, allow the motor to cool for one minute.
b. If the rotor does not turn freely in the pump
assembly. See Troubleshooting, page 20.
15. Remove the hose inlet from the pump outlet (L) and
walk the water out of the hose.
a. Starting at the pump, raise the hose bundle
above your head and slowly move towards the
applicator end. As you move towards the appli-
cator end, the remaining water will drain from
the hoses.
16. Perform Pump Pressure Setting procedure, page
12.
17. Reattach the hose to the pump outlet (L). The sys-
tem is ready to prime with material.
