Remove the cap

from the tubing at point 2.

Disconnect the

pump discharge line from the tubing

at point 4 and

connect it to the tubing at point 2.

Cap the tubing

at point 4.

Disconnect the pressure equalizer

solenoid

valve

plug P9 from receptacle J9.

Energize the pressure equalizer solenoid valve by

applying 24 volts dc across pins A and B of plug P9.

Start the pump and flush the line for

approximately

10 minutes, then turn the pump off.

Remove the cap from the tubing at point 5.

Remove the pump discharge line from the tubing at

point 2 and connect it the tubing at point 5.

Remove the recovery line from the valve at point 6

and connect it to the tubing at point 2.

Close the

valve at point 6.

Start the pump and flush the line for

approximately

10 minutes, then turn the pump off.

De-energize the pressure equalizer solenoid valve

removing the voltage source from pins A and B of

plug P9.

Disconnect the discharge and recovery lines from

the

tubing and remove all caps from the tubing.

(k) Refer to figure 5-22 and purge the system

with

nitrogen

Make sure caps are off the tubing at all points and

that the suction and discharge line service valves

are open.

Connect the nitrogen line to the tubing at point 1

and release nitrogen into the system for

approximately 5 minutes or until moisture ceases to

be discharged from the system.

Energize the bypass solenoid valve by applying

volts dc across pins A and B of plug P8.
