DANGER

Potentially explosive atmosphere

Explosion hazard if used in hazardous areas.
The device is not suitable for operation in hazardous areas
with potentially explosive atmospheres.
Do not expose the device to combustible or explosive gas mix-
tures.
CAUTION
Tilting risk
Damage of the device
Secure the device against any sudden translocation during
maintenance.
CAUTION
Hot surface
Burning hazard
According to the product type and operation conditions, the
temperature of the housing may exceed 50 °C during opera-
tion.
Depending on the conditions at the installation site it may be
necessary to provide these areas with appropriate warning
signs.
3 Transport and storage
The products should be transported only in its original pack-
aging or a suitable replacement.
When not in use, protect the equipment against moisture and
heat. Keep it in a covered, dry and dust-free room at a temper-
ature of -20 °C to +40 °C (-4 °F to 104 °F).
Outdoor storage is forbidden. As a matter of principle, the op-
erator must regard all applicable standards according preven-
tion of damage due to lightning, which may otherwise dam-
age the sample gas pump.
The storage room must not be equipped with any ozone-pro-
ducing devices like fluorescent light sources, mercury arc
lamps, electric high voltage devices.
Before restarting the pump after long-term storage or an ex-
tended standstill period, the insulation resistance of the wind-
ing phase-to-phase and phase-to-ground must be measured.
Moist windings could cause leakage current and flash-over.
The insulation resistance of the stator windings must be at
least 1.5 MΩ, measured at a winding temperature of 20 °C
(68 °F). For lower values, drying the winding is required.
The motor shaft should be rotated in regular intervals to en-
sure sufficient lubrication of the bearings in long term.
To do this, unscrew the three cross-head screws of the housing
cover and remove the cover (see fig. 1, fig. 2). The crankshaft is
now visible.
CAUTION
Contusion hazard
Contusion of the fingers
Don't have your fingers caught between eccenter and slide.

4 Installation and connection
Check the equipment for damage before installation. Among
other things, this could be a damaged housing, supply cables,
etc.. Never use equipment with obvious damage.

4.1 Requirements for the set-up location

CAUTION
Equipment damage
Protect the equipment, particularly gas connections and gas
lines, from dust, falling objects, 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.
The ventilation must be unobstructed and the exhaust air –
and from the adjacent units as well – must not be directly re-
siphoned.
The motor is rated for ambient temperatures between -20°C
and +60°C and for installation altitudes ≤ 1000 m above sea
level.
If installed without the mounting bracket, there must be suf-
ficient spacing between the motor and the rear wall. The fur-
ther environmental parameters for the set-up location can be
found in the data sheet at the end of the operating and in-
stallation instructions.

4.1.1 Outdoor installation

The sample gas pumps were not specifically designed for out-
door setup. The operating and environmental conditions are
crucial for the required types of protection and any additional
measures required, such as:
