Note: Anytime a sensor, pressure control assembly (board) or both are replaced,
the following calibrations must be performed.
PRESSURE CALIBRATION
1. Attach a 50', 1/4" airless hose, airless gun with 0.017 tip and a 5000 psi glycerin filled pressure gauge to
the pump.
2. Place the suction tube into a bucket of Airlessco Pump Conditioner and water.
3. Turn prime/pressure relief valve to the prime (open) position and prime fluid pump.
4.
Place the prime/pressure relief valve in the pressure (closed) position.
5. Slowly increase pressure using the control knob, while watching the glycerin guage. Maximum pressure
is to be 3000 psi. Adjust pressure using the set screw under label on top of pressure control knob.
Clockwise to increase pressure and counter-clockwise to decrease pressure. Trigger the gun a few times to
ensure maximum pressure is correct.
6. If pressure exceeds 3000 psi, use adjusting set screw under the label on the knob top. Turning the set screw
counter-clockwise will decrease the unit pressure.
ELECTRICAL BOARD CALIBRATION
PRESSURE CONTROL ASSEMBLY (Electrical Control Board)
1. Unplug machine's power cord.
2.
Remove four screws (Fig. 17, Item 12) from pressure control assembly.
3. Disconnect all leads from pressure control assembly.
4. Reassemble in reverse order.
PRESSURE CONTROL KNOB
1.
Unplug machine's power cord.
2. Remove four screws (Fig. 17, Item 12) from pressure control assembly.
3. Disconnect Pressure Control Knob wire from pressure control assembly.
4.
Unscrew Knob from Fluid Body fitting
4. Reassemble in reverse order, use liquid pipe thread sealer (PST) on threads, tighten to snug, then rotate 90 deg so wire is
tucked next to fluid body. Do Not Overtighten.
ON-OFF TOGGLE SWITCH
1. Lower the pressure control assembly as described above.
2. Disconnect the two wires on the switch.
3.
Use a 9/16" wrench to loosen the nut on the toggle switch shaft.
4. Reassemble in reverse order.
FUSE HOLDER
1. Lower pressure control assembly as described above.
2.
Disconnect the two wires on the holder.
3. Remove holder cover and fuse.
4. Use 11/16" wrench to remove the nut from the holder shaft.
5.
Reassemble in reverse order.
REPLACEMENT OF ELECTRICAL COMPONENTS
NOTE: Anytime the pressure control assembly, sensor or both are replaced, perform the calibrations.
Always unplug the electrical cord before servicing machine.
