Tensioning the V-belt
1. Remove the two side air intake
grills.
2. Loosen the screws (size 13) [7].
The screw on the opposite side
is not shown.
3. Set the pre-tension
of the V-belt with the (size 17)
nuts [8] and [9].
4. The press-down deflection depth
for the V-belts should be ca.
10 mm, "a thumb width".
5. Counter-lock the nuts [8] and
[9] again and then tighten
the two fastening screws [7]
again.
6. Re-fit the two air intake grills.

The unit does not start
1. Check power supply.
400 V/3~N/50Hz.
2. Move the operating switch
to the "I" (Heating) position.
3. The "Operating" indicator
light on the control panel must
illuminate.
4. Check the strapping connector
or the room thermostat plug,
if fitted, is seated properly and
making good contact.
5. Check the setting of the room
thermostat.
The temperature set must be
higher than the current room
temperature.
6. Check whether the safety
temperature limiter (STB) has
tripped.
To do so, remove the protective
cap next to the control panel.
7. Before an STB reset ensure that
the causes have been analysed
and rectified.
The following causes are
possible:
- The units were not able to cool
down because the electrical
connection was interrupted.
- Too high an outlet temperature
due to incorrectly implemented
air routing when operating with
hoses.
- Air inlets or outlets are not free
or are inadequate.
8. Check whether the "Burner
fault" indicator light
on the control panel is
illuminated. If this is the case,
then reset the automatic burner.
Troubleshooting
9. Move the operating switch
to the "II" (Ventilate) position.
If the supply air fan now starts
up the fault may well be in
the burner area.
Forced-air burner and power
supply
1. Check the oil filter(s)
for contamination. Replace
contaminated oil filter(s).
2. Check whether the shut-off
cock on the oil filter is open.
3. Check the fuel tank
for sufficient fuel level.
4. Check the heating oil
for paraffin separation.
Possible from 5 °C!
5. Check the oil hoses for damage.
6. Check the safety devices'
capillary tubes and probes
for damage or contamination.
7. Use appropriate means to check
that the temperature monitor
(TW) is functioning properly.
8. Check the forced-air
burner for possible damage
to the nozzles, baffle plate,
filter etc.
The supply air fan does not
start
1. Check the fan can move freely.
2. Check the controller fuse
in the switching cabinet.
3. Check whether the motor
protection switch in
the switching cabinet has
tripped.
4. Use appropriate means to check
that the temperature controller
(TR) is functioning properly.

The press-down deflection
depth for the V-belts should be
ca. 10 mm (a thumb width).
ATTEnTiOn
Before undertaking any work
on the units, the power
plug must be removed from
