10.3 CONDITIONS OF USE

• This manual:
MUST be read carefully and understood before carrying out any operations on the unit;
MUST be strictly complied with;
MUST always be at hand in the place where the unit is used.
• Installation must only be carried out by qualified personnel.
The maximum permissible pressure differentials given in the "SPECIFICATIONS" must never be exceeded. They are valid only under
the following conditions;

as a blower:
gas intake temperature 20°C (+68°F) and atmospheric pressure 1013 mbar (abs.) (29.92 In Hg ) measured at the inlet port

as an exhauster:
gas intake temperature 20°C (+68°F) measured at the inlet port and atmospheric backpressure 1013 mbar (abs.) (29.92 In
Hg).
If the unit is used for conveying flammable gases, installation in an open place or an area with forced air change is necessary.
When installed outdoors, protect the unit against the sun and weather.
The characteristics of the blowers/exhausters can vary depending on the following factors:
- variation in the absolute suction or outlet pressure with respect to the reference conditions (1013 mbar abs.);
