Pressure Control Adjustment - Graco EM 5000 Instructions-Parts List Manual

Pressure Control Adjustment

Use extreme caution when performing this calibra-
tion procedure to reduce the risk of a fluid injection in-
jury or other serious bodily injury, which can result from
component rupture, electric shock, fire, explosion or
moving parts.
This procedure sets the sprayer to 18.0–20.7 MPa,
182–207 bar Maximum Working Pressure.
Perform this procedure whenever the pressure control
assembly is removed and reinstalled, or replaced, to be
sure the sprayer is properly calibrated.
Improper calibration can cause the sprayer to over–
pressurize and result in component rupture, fire or ex-
plosion. It may also prevent the sprayer from obtaining
Service Tools Needed:
NEW 15.2 m, 21.0 MPa, 210 bar, flexible nylon, airless spray hose, p/n 223–541
0–350 bar fluid–filled pressure gauge, p/n 102–814
NEW spray tip, size 0.025 to 0.029
3/8 in. ignition wrench or nut driver
5 gallon pail and water or mineral spirits
Swivel, p/n 156–823
Nipple, p/n 162–453
Tee, p/n 104–984
WARNING
the maximum working pressure, resulting in poor
sprayer performance.
NEVER attempt to increase the fluid outlet pressure by
performing these calibrations in any other way. Never
Exceed 20.7 MPa, (207 bar) Maximum Working Pres-
sure. Normal operation of the sprayer at higher pres-
sures could result in component rupture, fire or explo-
sion.
ALWAYS use a new 50 foot (15.2 m) spray hose, rated
for at least 20.7 MPa, (207 bar) Maximum Working
Pressure, when performing this procedure. A used, un-
der–rated hose could develop a high pressure leak or
rupture.
