5.Open recirculation valves (AC, AD) for respective pump dispense side. Run pumps until the A and B reservoirs are empty. Salvage the material in sepa- rate, clean containers.
Empty and Flush Entire System (new sprayer or end of job)
9.Close recirculation valves (AC, AD) and open mix manifold valves (AH, AJ). Dispense fresh solvent through mix manifold valves and out gun.
AC 
NOTE:
AD
AC | AD |
AE | AF |
AH | AJ |
When priming or flushing the pumps, it is normal to get cavitation or pump runaway alarms. Clear the alarms
, and press 
again as necessary. These alarms prevent excessive pump speeds that can dam- age pump packings.
6.Wipe reservoirs clean, then add solvent to each. Move circulation lines to waste containers.
7.Repeat Step 4 to flush through each side until clean solvent exits recirculation hose.
8.Press 
. Move recirculation hoses back to reser- voirs. Continue recirculating until system is thor- oughly flushed.
10.Close mix manifold valves (AH, AJ).
11.Slowly open sampling valves (AE, AF) to flush sol- vent through until clean. Close sampling valves.
Press 
.
12.Follow Park Fluid Pump Rods, page 38.
13.Remove pump fluid filters, if installed, and soak in solvent. Clean and replace filter cap. Clean filter
14.Close main air valve (E).
NOTE:
Fill A and B pump packing nuts with TSL. Also, always leave some type of fluid, such as solvent or oil, in the system to prevent scale build up. This build up can flake off later. Do not use water.
