When installing the units,
the regulations and ordinances
applicable to the respective federal
state must always be observed.
It should also be noted:
■
The units must be installed in a
stable position
■
The units must be placed on
the floor in a safe and stress-
free manner, preferably on a
separate vibration-damped base
■
Make sure that the fan power
(nominal pressure) is adapted
to the respective air-side
resistances
Measure nominal
current!
■
Check that the inlet and outlet
are free
■
The supply of sufficient
combustion air must be ensured
■
If overpressure or underpressure
or significant air impurities
occur in the installation room, a
separate burner fresh air intake
(accessory) must be installed
■
If significant air pollution is to
be expected in the installation
room, the recirculation air
drawn in should be drawn in via
appropriate filters (accessories)
The resistance on the suction
side must be observed and the
fan power must be adjusted
accordingly!
Room thermostat connection
The room thermostat (accessory)
must be placed in a convenient
location for temperature control.
The thermostat probe must not be
located directly in the warm/cold
air flow and must not be mounted
directly on a cold base.
The same procedure must be
followed when installing an
automatic day/night temperature
control or other temperature
controls available as accessories.
Installation and assembly
Exhaust gas connection
The design must comply with DIN
18160 Part 1, the dimensions with
DIN EN 13384 Part 1.
■
Proper exhaust gas routing
must be ensured
■
The flue gas connection must
be carried out professionally in
accordance with the applicable
regulations
■
The flue gas connection may
only be made to a previously
approved flue gas system
Electrical connection
The electrical connection of the unit
must be carried out by authorised
specialists in accordance with DIN
EN 60335-1 and DIN EN 50156-1.
■
An emergency switch must be
fitted in an easily accessible place
on units with a nominal heat
power rating of more than 50 kW
■
The emergency switch must be
protected against unauthorised
operation
CAUTION
The transport pallet or timbers
must be removed before
installation.
NOTE
The air intake may only take
place via the intake openings
provided.
If the bottom of the unit is not
designed as an intake variant,
it must always be closed to
prevent false air intake.
NOTE
All connection terminals of
the electrical wiring are to be
checked for firm seating and
tightened as necessary.
