Flushing
I.When to flush.
DBefore the first time use
DWhen changing colors
DBefore fluid can dry or settle out in a dormant system (observe the recommended fluid pot life on catalyzed fluids)
DBefore storing the system
7.Open the pressure pot air shutoff valve (17b).
8.Set the pressure pot air regulator to 20 psi (138 kPa, 1.4 bar).
9.Open the gun fluid shutoff valve (18).
10.Hold the gun against and aimed into a grounded metal waste pail. Trigger the gun slowly. When fluid flows freely, release the gun trigger.
II.How to flush.
See Fig. 9.
1.Relieve pressure.
2.Remove the air cap before flushing. Clean it separately.
3.Remove the pressure pot cover. Remove the tank liner, if used. Pour in 1 gal. (4 liter) or place a
1 gal. (4 liter) metal pail of compatible solvent in the pressure pot. Install the cover and tighten the
4.Make sure the pressure pot and gun air regulators (33, 36) and the master air valve (A) is closed.
5.Be sure the air relief valve (7) is closed (clockwise).
6.Open the master air valve (A).
11.For a
For flushing after spraying fluid: trigger the gun and flush with solvent until the system is thor- oughly cleaned. Repeat with clean solvent if necessary.
12.Release the gun trigger, close the pressure pot air shutoff valve (17b).
13.Relieve pressure.
14.Open the tank and clean the inside of the tank and its suction tube.
15.You are now ready to prime the system with another fluid or to store the system. Relieve pres- sure if you are storing the system.
