Spray With The Isolation System - Graco HydroShield WMBL00 Instructions - Parts Manual

Operation
Spray with with the the Isolation Isolation System
Spray Spray with the Isolation
Contact with the charged components of the spray
gun will cause an electric shock. Do not touch the
gun nozzle or electrode or come within 4 in. (102
mm) of the front of the gun during operation or
until performing the Fluid Voltage Discharge and
Grounding Procedure, page
Follow the Fluid Voltage Discharge and Grounding
Procedure, page 29 when you stop spraying and
whenever you are instructed to discharge the
voltage.
1. Prime the isolation system. Follow
Prime the Isolation System, page
2. Set the gun fluid and air settings. See
Adjust the Gun Fluid and Air Settings, page
3. Put the system into Spray mode
The isolation fluid pump automatically fills. The
light tower indicates the fluid level in the pump
as it fills or dispenses.
These set points can be customized in the
system settings on Pump Screen 1. See
Pump Screen 1: Pump Volume, page
Light Definition
Light Light Definition Definition
Green (solid) The pump is 50% full or more.
Yellow (solid) The pump is less than 50%
full but more than 10% full.
Red (solid) The pump is less than 10%
full.
Note
To enter Spray mode, you must first be
in either Prime or Standby mode. You
cannot enter Spray mode directly from
Purge mode.
If color change is enabled, the system
remembers if it still has flush material
in the pump. The system will not allow
Spray mode to be entered until the pump
has been emptied in either Purge or
Prime mode.

4. Turn the electrostatics on at the gun. Verify
that the ES indicator or Hz indicator is green.
Adjust the gun air pressure if needed. See gun
manual for details. Adjust the gun fluid pressure
according to the Gun Setup procedure in your
gun manual.
5. When the gun is triggered:
• The control interface displays the voltage
building in the system.
• The system raises the ground rod (N) in
the cabinet. When the ground rod symbol
disappears and the charge symbol appears,
the system is capable of building a charge.
See Home Screen, page
6. When the trigger on the gun is released and
the ground rod delay time has elapsed, the
ground rod (N) drops and discharges the system.
Release the gun trigger at any time to refill the
system.
Tips:
• Trigger air only to fully charge the system
before spraying
• To maintain a higher spraying voltage,
increase the ground rod delay time as far as
practical. However, increasing the ground
rod delay time also slows the fill time. See
System Screen, page
7. When approaching the end of painting, activate
the Do Not Fill button
preventing the isolation fluid pump from filling
unnecessarily.
8. When finished painting, release the trigger, turn
the electrostatics off at the gun, and put the
system in Standby mode
9. At this point, you may perform any of the following
actions:
• Supply more paint to the system. See
Prime the Isolation System, page
• Flush and clean the system. See
Flush the System (Systems without Color
Change), page 31.
• Shut down the system. See
Shutdown, page
