Power Supply
Prior to performing the electrical installation in line with
local requirements, check whether it is possible for even
a temporary power overload to cause an impermissible
undervoltage.
To connect the units, the line cross-sections are to be
placed in such a way that they do not caused the burner
voltage to lower to an impermissible level when the fan
is started.
When connecting the units in the 400 V series, make
sure that the phase sequence of the rotational field is
correct. The fan could rotate in the wrong direction if this
connection is not correct.
An easily accessible emergency switch must be at-
tached in the setup room, but not close to hazardous ar-
eas.
G
All generally accessible switches must be
protected against damage and unauthorised use!
Outside Setup
Units that are set up outside must be adequately pro-
tected from weather conditions so that they do not have
any harmful effects or cause any unreasonable annoy-
ances during operation.
The units may only be equipped with armatures and
control devices that are suitable for outside use. If not,
the control devices and switches must be protected ac-
cordingly.
Wall Assembly
The wall where the unit is to be assembled may not be
made of flammable materials. Its load-bearing capacity
must be tested and, if necessary, reinforced.
Consoles must be anchored firmly to the wall and the
units attached here. There must be adequate room to
perform maintenance work on the heat-exchanger,
burner, fan and exhaust system.
You must observe the following.
à Operating mechanisms for the unit and the combus-
tion air supply must be able to be operated from the
ground.
à Tools needed for monitoring, service and repair work
must be supplied by the operator.
Assembling Suspended Units
The units may only be attached to sturdy structures or
ceilings that are made of non-flammable materials and
have adequate load-bearing capacity.
Sturdy mounts fixed on the unit are used to attach it. In
addition, the requirements listed in the section “Wall As-
sembly” must be observed.
Fuel Supply
Particularly for heating oil lines, make sure that the
cross-section of the lines corresponds to the suction
height, the total line resistance and increased viscosity
at lower temperatures and, if necessary, it is possible to
connect an oil transport device.
The lines must be placed in such a way that they are
easily ventilated and are protected from corrosion and
mechanical damage.
G
The measured pressure of the suction line should
not exceed -0.3 bar. It may be a maximum of -0.4 bar.
Annual Inspection and Service
The operator must have the unit checked and serviced
as necessary, at least once a year, by a representative
of the manufacturing company or another authorised in-
dividual in accordance with the operating conditions.
The units must be checked for operational readiness,
functional safety, efficiency and compliance with emis-
sion limits.
The operator must be informed if defects are found. He
must then have the unit serviced immediately or its
components replaced.
The following applies:
Maintenance work on limiting devices, self-
adjusting devices and flame monitoring devices as
well as on other safety mechanisms may only be
performed by the respective manufacturer or his
representatives.
On the other hand, the individual contracted to
service the unit may only replace components or
assemblies with those provided by the manufac-
turer or his representatives.
G The units are intended to be used exclusively for
industrial and commercial purposes. They are not
intended to heat residences or similar rooms.
