REMKO VRS-C Series
Mounting on the ground
The units must be set down stably
on a non-combustible surface
away from traffic zones - by crane,
for example.
To protect the units from damage
in commercial premises, for
unhindered maintenance and
repair on the unit and burner, and
for unhindered
air intake and exhaust, a protective
zone of 1 m around the unit must
be kept clear.
This protection zone shall be
marked by a sign with the
following inscription:
Fixed demarcation is recommend-
ed for frequently used areas.
Wall installation
The wall intended for installation
must also consist of non-
flammable materials. Its load
capacity must be checked
(reinforcements must be installed
when necessary).
The brackets must be sufficiently
anchored to the wall and the units
must be securely fastened to them.
Sufficient clearances for
maintenance of the heat
exchanger, burner, fan and flue gas
system must be provided.
■
It must be possible to actuate
control elements for the units
and fuel supply from the
ground
■
If auxiliary equipment is
required for monitoring,
maintenance and repair work,
this must be provided by the
operator
Mounting hanging units
The units may only be mounted on
stable structures or ceilings made
of non-flammable construction
materials and with sufficient
bearing capacity.
The fastening must take place with
suitable anchors, which are to be
securely fastened to the unit.
The requirements listed in the
“Wall mounting” section must also
be observed.
Room heating
Fan-assisted heaters may only be
operated in closed rooms and halls
via a room thermostat.
Fuel supply
The fuel supply must be installed
in accordance with DIN 4755 for
oil-fired warm air heaters, DVGW
Code of Practice G 600 for gas-
fired warm air heaters and TRF for
liquid gas.
Particularly in the case of heating
oil pipes, care must be taken to
ensure that their cross-section is
sufficiently large.
The suction lift, the total line
resistances and increased viscosity
at lower temperatures must
be taken into account in the
determination.
Appropriate separate oil
production units may need to be
provided.
The lines must be laid in such a
way that they can be easily bled
and are protected against corrosion
and mechanical damage.
Electrical installation
Ensure that an impermissible
undervoltage due to a mains
overload is not possible, even if
this is only temporary.
For the connection of the units,
use cables with cross-sections that
do not cause an impermissible
drop in voltage even when the fan
starts up.
When connecting the units in
400 V version, ensure the correct
phase sequence of the rotating
field (right).
An incorrectly made connection
can lead to the fan turning in the
wrong direction.
An emergency switch must be
fitted in an easily accessible place
in the room where the unit is
installed for units with a rated heat
power of 50 kW or more.
Protection zone
Keep a distance of 1 m

CAUTION
The measured pressure of the
suction pipe should not exceed
minus 0.3 bar and must not
exceed minus 0.4 bar.
CAUTION
All switches, if generally ac-
cessible, must be protected
against damage and unauthor-
ised use!
CAUTION
The electrical connection of
the unit must be carried out
by authorised specialists in ac-
cordance with DIN EN 60335-1
and DIN EN 50156-1.
