Motor Position
The motor position must be set for the volume mix ratio
of the system.
NOTE: Changing the motor position does not change
the mix ratio.
Check Motor Position
1. Verify that the correct pumps are mounted for your
volume mix ratio. See the Models chart on page 10.
2. Verify that the motor position is adjusted correctly
for that volume mix ratio. If not, perform the
following
Change Motor Position procedure.
Change Motor Position
There are specific motor positions for each mix ratio
setting. To Adjust the position of the air motor:
1. Verify that the XP-hf motor air valve (CA) is closed.
2. Perform the Check Motor Position procedure. If
the position is incorrect, continue to the next step.
3. Loosen the eight fasteners and remove the two
pump guards.
If your sprayer is intended for hazardous locations, a
qualified electrician must connect the explosion-proof
heater wiring. Ensure wiring and installation comply
with local electrical codes and regulations.
Improperly installed or connected equipment may
result in fire, explosion, or electric shock. Follow all
local codes and regulations.
