Ventilation; Vibrations; Residual Pressure; Safety Devices - SAMES KREMLIN PPH 308 User Manual

1.5.10. Ventilation

Do not start painting with the PPH 308 until the spraying booth ventilation system is operating. If
the ventilation is cut, toxic substances such as organic solvents or ozone may remain in the
spraying booth, resulting in a risk of fire, poisoning or irritation.

1.5.11. Vibrations

If the atomizer vibrates more than usual, the cause is generally unbalanced rotating parts.
There may be dry paint deposits on the bell cup or rotor. If any of these situations arise, it is
essential to correct them. Excessive unbalance may damage the turbine resulting in failure to
operate or even loss of the bell cup / turbine connection, presenting a risk for persons and
equipment.
WARNING : The warranty does not cover damage caused by imbalance of rotating parts.

1.5.12. Residual pressure

Before all maintenance or repair operations, remove paint and solvent from the atomizer,
switch off the high voltage power supply and cut the paint, solvent and air supplies, then
release residual pressure in each supply system. Residual pressure may lead to component
damage and expose personnel to serious injuries. Paint or solvent dispersion may also lead to
poisoning or irritation.

1.5.13. Safety devices

During installation of the PPH 308, it is important to set up safety devices enabling high voltage
power, paint, solvent and air supplies to be cut immediately if there is a problem.
• Detection of control system faults.
• Detection of high voltage surges associated with the SAMES HV generator.
• Detection of air pressure drops.
• Detection of ventilation failure.
• Detection of fire.
• Detection of human presence.
• Detection of turbine rotation speed faults.
Failure to use such safety systems could cause a fire hazard, put operating staff at risk of serious
injury and damage the equipment.

1.5.14. Mechanical collision

The warranty does not cover damage resulting from the operating environment (e.g.: collision
with robot).

1.5.15. Ambient temperature

The atomizer is designed for normal operation at an ambient temperature of between 0°C and
+ 40°C.
To optimise the quality of application, recommended operating temperatures are between +
15°C and + 28°C.
The storage temperature must never exceed +60°C.
