Evolver 303 Dual Purge Robotic Atomizers - Maintenance
SERVICE
Because we want to provide our users with the most
up-to-date technology possible, we are constantly
seeking to improve products. If a change in product
configuration occurs after it is on the market, we will
implement that technology in future production and,
if practical, make it available to current users. The
following service information is based on standard
specifications and procedures for this product. If you
find some minor deviations between this information
and your equipment because of design or manufac-
turing changes, contact your Ransburg representative
to resolve the difference.
> As the spray head is removed from the valve
manifold assembly, a certain amount of residual
fluid may be present. Care must be taken not
to allow this fluid to drain into the high voltage
terminal rings or air passages.
> Eye protection should be worn while servic-
ing applicator.

> An electrical discharge or spark may create an
electrical and/or fire hazard during maintenance.
Do not service the spray applicator with the
power supply on. Verify that the power supply
on/off switch has been turned off.
> Unexpected robot movement can be hazard-
ous. Do not adjust or repair the spray applicator
when the robot is operating or waiting to start.
The robot must be locked out and tagged out
per OSHA prior to removing the applicator from
the robot manifold assembly.

Before performing any work on the spray applicator,
always flush the fluid passages, blow dry with push-
out air, and wipe the spray applicator clean. Refer to
"Applicator Cleaning" in the "Maintenance" section
for instructions on how to properly clean the spray
applicator. Depressurize all fluid and air passages
before removing the applicator from its manifold.
Always work in a clear, clean space to minimize part
loss and damage.
SPRAY HEAD ASSEMBLY
> Disassemble the spray head only
enough to remove and replace defective
parts. For instance, if only replacing the
front electrode it is not necessary to remove
the fluid nozzle.
NOTE
> At assembly, apply a small amount of
dielectric grease to grooves in spray head
and valve manifold to reduce high voltage
breakdown. Excessive grease will not allow
spray head [5] to seat fully against mounting
block assembly [3] (see Figure 15).
> To prevent damage, always lubricate
the o-rings located on the underside of the
spray head.
