Outdoor installation
■
Operation of the units
must not present a hazard
or unreasonable discomfort
■
The unit operator must
ensure that it is not possible
for unauthorised persons
to manipulate either the unit
or the power supply
■
Precipitation such as rain or
snow can be sucked in through
the supply air fan.
For this reason suitable weather
protection should be provided
Exhaust gas ducting
It is also possible to operate
the units outdoors or in open halls
without special-purpose exhaust
ducting.
To protect individuals against
inconvenience and to prevent
precipitation from penetrating
the combustion chamber, a 1 m
exhaust pipe with an integrated
rain hood (accessory) should
always be fitted to allow for safe
removal of exhaust gases.
If the unit is installed indoors
(enclosed halls), exhaust ducting
must be fitted in accordance with
the applicable regulations.
NOTE
In order to avoid the combustion
chamber being damaged due
to moisture (condensate) from
the exhaust ducting, make
sure that the exhaust system
is correctly installed with
a condensate trap.
NOTE
Paraffin formation can start
at temperatures below 5°C.
To avoid this appropriate
preventative measures must
be implemented, e.g. winter
Diesel.
Fuel supply
An adequate fuel supply
that makes use of suitable and
approved safety tanks and suitable
pipelines must be provided
by the customer.
The suction line in the base of
the tank must be fitted with a foot
valve as a matter of principle.
It must also be ensured that
the line cross-section is suitable for
the total line resistance, the suction
height and increased viscosity
at low oil temperatures.
Under certain circumstances,
it may be necessary to use an oil
feed unit.
The respective local regulations
and the TRbF 20 regulations must
be adhered to at all times.
Even at low temperatures,
an adequate supply of flowing
heating oil must be ensured.
■
The factory-fitted oil pre-
heating system is only active
if the unit is connected to
a functional mains socket
and the ambient temperature
is lower than 10°C
■
It is not possible to rectify
paraffin separation that has
already occurred using the pre-
heating system.
If paraffin has already formed
it is necessary to clean out
the complete fuel system
Electrical connection
■
The units are operated with
400/3N~/50 Hz three-phase
current
■
The electrical connection
is made using a built-in mains
cable with a 16A CEE plug
■
The mains cable must
be selected based on
the connection power
of the unit and the cable length
while also taking the local
circumstances into account
■
Cable extensions must be
suitable for the application
and may only be used in fully
unreeled or reeled off condition
NOTE
The electrical connection for
the units must be made at
a separate feed point with a residual
current device in accordance with
VDE 0100, Section 55.
ATTENTION
Work on the electrical
installation must be performed
exclusively by authorised
specialists for safety reasons.
ATTENTION
All cable extensions must only
be used in fully un-reeled
or reeled off condition.
