Evolver 202 Robotic Atomizers - Maintenance

Note: To check for fluid leaks, it is easiest to first remove the applicator from the test station and remove the shroud
from the applicator. Then the applicator can be remounted to the test station. Leak detector may be used at all
appropriate sources. Be certain to wipe off all residual solution using a non-conductive solvent such as Naphtha.

General Problem

Possible Causes

Corrective Action

1. Insufficient back pressure

to fluid regulator

2. Fluid regulator does not

control flow (system)

3. Diaphragm stretched from

excessive air pressure

4. Ruptured diaphragm

5. Inconsistent air pilot supply

1. Ruptured Diaphragm

1. Damaged o-ring(s) on outer

diameter of valve body

2. Damaged or worn needle

seals inside valve assembly

1. Diaphragm (screws) loose

2. Ruptured diaphragm

1. Replace fluid tube with the next smaller inner

diameter size.

2. Disassemble fluid regulator and inspect for

failed components (system).

3. Rebuild regulator.

4. Rebuild regulator.

5. Check air source.

1. Replace regulator diaphragm.

1. Replace o-ring.

2. Inspect tubing coil for scratches and replace if
