4.1 Requirements to the installation site
CAUTION
Equipment damage
Protect the equipment, particularly gas connections and gas lines, from dust, falling ob-
jects, as well as external blows.
Lightning
On principle, the operator must meet all applicable standards with respect to preventing
damage to the equipment due to lightning, which could result in equipment damage.
CAUTION
Avoid vibrations and resonances
The operator is responsible to mount the pump in a way that vibrations and resonance
do not cause premature failure resulting in creating an effective ignition source.
Mounting, installation and demounting the pump must be carried out in non-hazardous area and with pump cooled down.
Air ventilation must not be obstructed and exhausted air - including air from adjacent units - must not be sucked in directly.
Motors with mains voltage
110 - 120 V or 220 - 240 V
are suitable for ambient temperatures from
-20
°
C to +50
°
C
and altitude of
height ≤ 1000 m above sea level. Motors with mains voltage from
380
–
420 V
must be operated only in ambient temperature
range between
-20
°
C to +40
°
C
.
When mounting the pump without brackets, leave enough space between motor and rear wall. Please refer to the data sheet at-
tached to this manual for further information about ambient parameters at the installation site.
