1.5.8. Maximum Speed
Excessive turbine speed can result in serious damage to the turbine and loss of connection
between the bell cup and turbine, presenting a risk to persons and equipment. The speed must
not exceed 45,000 rpm.
WARNING : The guarantee does not cover damage resulting from a rotation speed greater than
45 000 tr/min.
1.5.9. 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 essen-
tial to correct them. Excessive unbalance may damage the turbine resulting in failure to oper-
ate or even loss of the bell cup / turbine connection, presenting a risk for persons and
equipment.
WARNING : The guarantee does not cover damage caused by unbalance of the rotating parts.
1.5.10. Bell Cup / Turbine Fitting
The bell cup must be correctly fitted on the turbine, a snap must be heard; the two cylinders
must fit on top of each other without any foreign matter between them. If fitting is incorrect, the
connection may be lost and the bell cup thrown out still spinning, presenting a risk for persons
and equipment.
1.5.11. O-ring Seals
Use the seals recommended in this manual. For solvent-based products, seals in contact with
the product must be chemically inert seals resistant to swelling or chemical attack. The PPH 308
is only guaranteed to operate correctly if it is used with seals whose size and material conform
to this manual.
1.5.12. Ventilation
Do not begin applying paint with the PPH 308 before starting up the ventilation system in the
spraying booth. 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.
1.5.13. 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 leadto component
damage and expose personnel to serious injuries. Paint or solvent dispersion may also lead
topoisoning or irritation.
