The basic quattro may only be operated:
• Indoors;
• Up to an altitude of 2,000 m [6,500 ft] above sea
level;
• At an ambient temperature of 5 - 40°C
[41 - 104°F]
;

• At a maximum relative humidity of 80% at 31°C
[87.8°F], decreasing linearly to 50% relative humidi-
ty at 40°C [104°F]
;
*)
• With a mains power supply where current fl uctua-
tions do not exceed 10% of the nominal value;
• Under level 2 contamination conditions;

relative humidity of up to 80%. At temperatures between
31 - 40°C [87.8 - 104°F], the humidity must decrease
proportionally in order to ensure operational readiness (e.g., at
35°C [95°F] = 65% humidity; at 40°C [104°F] = 50% humidity).
The unit may not be operated at temperatures
above 40°C [104°F].

3. Safety Information

• Always disconnect the unit from the
compressed air and power sources prior to
beginning any maintenance work.
• When working on the tank (fi lling up, clea-
ning, maintenance) wear protective glasses
for protecting your eyes.
• Any residue of abrasive material on the
gasket may lead to leakage and early wear of
the gasket. After fi lling up clean the thread
and the gasket and close the lid properly.
• Solvents and tensides can create micro-
cracking in the plastic (danger of explo-sion!).
Clean the tank and the lid only with a dry
cloth. Do not write or stick something on the
tanks.
• Check the tanks and the lids regularly on
damages and replace them in case of doubt.
