Hot Air Distribution
The units are equipped with a high-performance axial
fan. This fan has been designed to transport the hot air
directly and effectively.
It is preferable to distribute air by means of pipes or
special hot air hoses. Warm air may only be distributed
in accordance with the fan capacity of the unit in opera-
tion. Please follow these instructions when attaching
warm air hoses:
à Use only warm air hoses approved by our company.
à The internal overlapping at the seams must point at
air direction.
à Make sure that the hoses and/or pipes are securely
attached to the unit’s air outlet connection.
à To prevent heat from building up, the pipes and
hoses may not have sharp kinks and bends.
à Counter pressure may not be allowed to build up
when using hoses to heat closed rooms.
à If suction temperatures increase or if there is resis-
tance on the air output opening, the forced-air burner
can be switched off at short notice by the tempera-
ture monitor (TW) in heating mode.
When the temperature falls, the burner restarts auto-
matically.
à If the intervals are too short, the length of the warm
air hoses should be checked.
à Avoid starting the burner in frequent cycles.
Under 5 min.
G If the motor protection relay is operated when set to
“Automatic Reset“, the motor may be damaged.
This is not covered by the guarantee!
Important hint about the motor protection relay
The motor protection relay made only be operated when
set to “Manual Reset“. The relay may not automatically
switch on again after cooling off.
Directing the incoming air.
There are three optional modes for unit operation: fresh air
mode, mixed air mode and circulation mode. The following
information is applicable, when the unit is installed outside
of the room to be heated.
Fresh air mode:
Air is suctioned in through the two air suction grilles fit-
ted at the factory
Mixed air operation:
To operate the unit with mixed air, it is necessary to
mount an air suction connection instead of an air suc-
tion grille. This connection can be purchased as an ac-
cessory. To ensure an adequate air supply, make sure
that the second air suction grille is not covered.
Circulation mode:
To operate the unit in 100 % circulation mode, it is nec-
essary to mount air suction connections (can be pur-
chased as accessories) instead of the air suction grille
supplied with the unit.
G
When the temperature is too high on the unit’s
outgoing air side, the heating-operation is inter-
rupted automatically by the STB!
Paraffin accumulation at low outside temperatures
A sufficient amount of heating oil must be able to flow
freely even when temperatures are low.
à Paraffin can accumulate even at temperatures below
5 °C.
à Appropriate measures must be taken to prevent this.
Use winterised heating oil or winter diesel.
G
Flexible fuel tubes must be protected from being
damaged, e.g. from forklifts, animals, etc.
Before Starting
Prior to initial operation, check the unit for any visual de-
fects on the control and safety devices, that the unit has
been installed correctly and that it has been properly
connected to the mains.
Observe the following points:
à Install the unit in a stable position.
à Make sure that air is supplied for combustion and
avoid overpressure and underpressure in the room
where the unit has been installed.
à Make sure that the air can be sucked in and be ex-
hausted freely.
à Make sure that enough fuel is supplied.
à Please note: the multifilex oil preheater will only func-
tion properly if voltage is supplied to the unit for a
longer time prior to initial operation.
à Use only clean heating oil or diesel.
Do not use bio diesel.
à Note that the cross-section of the fuel line must be
designed in accordance with the total line resistance,
the suction height and increased viscosity at lower
temperatures.
In some cases, an oil transport aggregate must be
used.
à Tightly seal the suction line at the bottom of the tank
with a foot valve.
à The waste gas values of the oil-burner are to be
checked and properly adjusted by authorised per-
sonnel to ensure compliance with local require-
ments.
G
Air lines attached to the air intake side must always
have a form-resistant (no unstable hoses) design.
