conditions (heated product) and not on the device (frictional heat).
Ignition temperature of the coating product
Ensure that the ignition temperature of the coating product is above the maximum
surface temperature.
Ambient temperature
The permissible ambient temperature range is: 10 °C to 60 °C; 50 °F to 140 °F.
Medium supporting atomizing
To atomize the product, use only weakly oxidizing gases, e.g., air.
Surface spraying, electrostatics
Do not spray device parts using electrostatic equipment.
Cleaning
If there are deposits on the surfaces, the device may form electrostatic charges. Flames
or sparks can form during discharge.
Remove deposits from the surfaces to maintain conductivity.
Use only a damp cloth to clean the device.
