Unit description
The units are portable, directly
fired fan-assisted heaters (WLE)
with heat exchanger and exhaust
gas connections exclusively for
commercial applications.
The units can be directly fired with
EL heating oil or diesel fuel and
may be operated with or without
an exhaust gas duct.
The units are equipped with a
4-part fuel filter system, highpressure atomisation burner
with optical flame monitoring,
low-maintenance axial fan, room
thermostat socket and mains cable
with earthed safety plug in IP 67
design.
The filler cap is equipped with
a surge-resistant venting valve.
This generates a negative pressure
in the fuel tank during operation
(slight hissing when opening
the filler cap).
The units conform to the
fundamental health and safety
requirements of the appropriate EU
stipulations. The units are reliable
and easy to operate.
The units may be used for the
following (inter alia) :
■
Heating tents/marquees
■
Spot heating workplaces
in open, non-flammable
manufacturing facilities and
halls
■
Temporarily heating enclosed
and open spaces
■
De-icing machines, vehicles and
non-combustible warehoused
goods
■
Maintaining the temperature of
frost-sensitive goods
Operating sequence
The supply air fan switches on
once the units are switched on in
heating mode or if heat is required
(fully automatic unit operation
with room thermostat).
The solenoid valve opens the fuel
supply to the oil nozzle following
burner pre-ventilation.
The fuel atomised under high
pressure is enriched with a
quantity of oxygen appropriate to
the heating capacity and ignited by
an electrical spark.
As soon as a flawless flame has
been generated, the automatic
burner begins optical flame
monitoring.
Warm air is blown out after a short
period of time.
The automatic burner executes all
unit functions fully automatically
and ensures reliable monitoring.
In the event of malfunctions or an
unstable or extinguished flame,
the automatic burner switches
the units off.
The unit's fault lamp will light up
in this case. The units can only be
restarted after manually resetting
the automatic burner.
After switching off the units via
the operating switch or the room
thermostat, the supply air fan runs
to cool the combustion chamber
for a certain time and then
switches off automatically.
Depending on the heat
requirement, the operating
sequence described is repeated
fully automatically when in
thermostat mode.
Safety temperature limiter
(STB)
The heating function is
permanently interrupted by
the safety temperature limiter
(STB) in the event of the units
overheating or malfunctioning.
In the event that the STB is
triggered, a fault shutdown of
the automatic burner occurs.
A manual reset of the STB can only
be implemented after the units
have cooled down.
ATTENTION
If the safety temperature
limiter has been triggered,
the cause of the malfunction
must be identified and rectified
before a reset is performed.
The resetting of the STB is
implemented by actuating
the reset key 2.
1. Unscrew the protective cap 1.
2
1
2. Carefully press in the reset key
2 with a suitable tool.
3. Screw the protective cap 1 back
on again.
4. Reset the automatic burner.
NOTE

exceedance of the triggering
temperature the operating
conditions of the unit should
be checked before resetting
the STB.
ATTENTION
Safety devices must not be
bypassed or disabled.
