TM 5-4120-339-14

(e) Start the pump and flush the line for approximately 10 minutes, then turn the pump off.

(f) Refer to figure 3-13 and disconnect plug P10 (3) from receptacle J10 (4) on the junction box.

(g) Energize the liquid line solenoid valve by applying 24 volts dc across pins N and M of plug P10.

(h) Start the pump and flush the line for approximately 10 minutes, then turn the pump off.

(i) Switch the pump lines so that the discharge line is connected to the valve at point 3 and the recovery

line is connected to the tubing at point 1.

(j) Start the pump and flush the line for approximately 10 minutes, then turn the pump off.

(k) Close the suction pressure service valve and move the discharge line from the valve at point 3 to the

tubing at point 2.

(l) Start the pump and flush the line for approximately 10 minutes, then turn the pump off.

(m) De-energize the liquid line solenoid valve by disconnecting the dc voltage source from pins N and M

of plug P10.

(n) Start the pump and flush the line for approximately 10 minutes, then turn the pump off.

(o) Uncap the tubing at point 4 and 5.

(p) Disconnect the pump discharge line from the tubing at point 2 and connect it to the tubing at point 5.

(q) Disconnect the recovery line from the tubing at point 1 and connect it to the tubing at point 4.

(r) Cap the tubing at points 1 and 2.

(s) Start the pump and flush the line for approximately 10 minutes, then turn the pump off.

(t) Move the pump discharge line from the tubing at point 5 to the valve at point 6. Cap the tubing at

point 5.

(u) Open the discharge pressure service valve.

(v) Start the pump and flush the line for approximately 10 minutes, then turn the pump off.

(w) Switch the pump lines so that the discharge line is connected to the tubing at point 4 and the recovery

line is connected to the valve at point 6.
