9.1 Installation advice
The portable pump was developed in accordance with the standards
EN1028 or EN14466.
According to EN11466 the maximum permissible ambient temperature of
the portable pump is 35 °C. The propulsion engine output is reduced at
higher ambient temperatures. If the intake air temperature rises above 52°
C, the propulsion engine output is also reduced (see Information screen
page).
Installation of the portable pump in a vehicle does not comply with the
EN14466. standard. Additional measures must therefore be observed with-
out which damage to the portable pump and the vehicle may occur
Note the following when selecting the installation position of the portable
pump:
• Allow unrestricted access for service work.
• The hot exhaust air flow from the propulsion engine may not be sucked
back in.
• The air intake of the engine cooling and the air intake of the propulsion
engine must be arranged in such a way that the fan and the propulsion
engine can always suck in sufficient fresh air.
Fresh air must be drawn in over the entire air intake cross-section
of the engine cover.
• The air intake cross-sections must be sufficiently large over the entire
air flow to avoid a reduction in output due to overheating of the propul-
sion engine.
• External air inlets must not be relocated, sealed or draw hot air from
any other source before commissioning.
• When installing without the fresh air intake described above, a dis-
tance of at least 1 m must be maintained between the rear side of the
portable pump (air intake opening) and the nearest partition wall.
• The air inlet between the runners of the portable pump may not be dis-
placed or obstructed to allow heat radiation from the exhaust system
to escape.
• The exhaust gases must be discharged into the open air via an addi-
tional elastically mounted exhaust pipe.
The exhaust gas temperature can reach up to 800 °C.
The exhaust pipe, diameter 50 mm (2 in) may not exceed a length
of 1500 mm (59 in).
A reduction of the diameter is not permitted
A maximum of two 90° bends with a radius of 250 mm (9.84 in)
may be used to discharge the exhaust gases.
When designing the exhaust pipe, there must be no backflow of
exhaust gas to the portable pump.
• The suction and discharge lines to the portable pump must be elasti-
cally supported.
