General notes
• It is essential to observe the instructions for installation and
operation! Non-observance can lead to injury or damage to
the system! During electric installations, the national rules
and safety regulations in effect regarding the dealing with
electrical devices must also be adhered to!
• Do not exceed the permissible electrical voltage, operating
pressure and compressed air temperature (see Technical
Data)!
• Carry out installation works only when the system is pres-
sureless, deactivated and cooled down! De-pressurise the
system and disconnect the device from the mains voltage!
If there is a leak in the compressed-air supply or discharge
line at the compressed-air heater, first deactivate the com-
pressed-air system. Only then may the leak be eliminated.
Leaks at the compressed-air heater itself require complete
replacement of the device!
• The compressed-air heater must not be repaired by oneself
but returned to the manufacturer.
• The compressed-air heater will only function when voltage is
applied.
• Installation and electrical connection must only carried out
by suitably qualified personal.
• The device is to be installed with the compressed air inlet
azt the top and the elctrical connection at the bottom (see
functional diagram).
• Only use temperature- and pressure-resistant components
(tubing, seals, sealant....)
• Use only suitable material for thermal insulation of the de-
vice (392°F).
• Avoid chemically aggressive environments or cleaning with
aggressive agents!
• Protect device during operation against the external impact
of drip or splash water!
• A pre-heating phase of approx. 10 minutes prior to the actual
employment should be taken into account, as the heating-up
process is regulated by the electronic circuit and deliberately
undertaken slowly.
• Do not touch the device and pipes near the device during
operation! Although the device is equipped with an inter-
nal thermal overload protection, temperatures may rise to
176°F during standstill (no compressed-air withdrawal)! You
may need to protect the device against accidental con-
tact (see recommended accessories). At short intervals
compressed-air withdrawal / standstill, the compressed-air
temperature may, for a short period of time, exceed 140°F.
• Pull out the connector plug during longer standstill periods
of the plant or de-energise the device. The socket for con-
necting the device plug should therefore be easily acces-
sible. Ensure that the device's connecting cable cannot
come into contact with the housing of the compressed
air heater!

• Check the device regularly to ensure correct functioning and
avoid damage!
- Check the device regularly for damage to the container
and the cable. Replace it, if required.
- For the point of installation, the following needs to be tak-
en into account
- No strong vibrations via tubing or fixing
- Good ventilation to prevent heat accumulation
- No direct contact to or insufficient distance from inflam-
mable materials
Function
The filter heater consists of a CLEARPOINT housing, in the
container (2) of which a compact screw-in part (3) with a heat-
ing element (4) is installed at the bottom. The screw-in part (3)
also contains a pressure-resistant shielded temperature sen-
sor (5). An internal sleeve (6) is fixed centrally between head
(1) and screw-in part.
At the bottom part of the device is the electric housing (7), into
which the voltage supply (standard connecting cable with a
plug connector) and a printed circuit board (8) are integrated.
A potentiometer (9) is installed on the circuit board which can
be adjusted via a lever (10) protruding laterally at the bottom.
With this, the maximum temperature of the leaving com-
pressed air is adjustable (adhesive labels with limit values, see
also "Technical data"). The electric housing is equipped with
an excess pressure protection (11), in case leaks between the
container (2) and the electric housing (7) should exist.
The compressed-air entering at the filter head (1) is distrib-
uted and flows downwards in the container (2). Heating-up,
which is measured continuously with the temperature sensor
(5), is implemented via contact with the heating element (4).
Via the centrally installed internal sleeve (6), the heated com-
pressed air flows towards the outlet at the filter head (1) and
then towards the compressed-air application.
The temperature sensor (5) and the electronic control which
are integrated into the printed circuit board (8) guarantee the
observance of the maximum surface temperature. Due to the
minor thermal mass of the heating element and to exact regis-
tration of the compressed-air temperature, fast adjustment of
the heating power within the performance curve of the device
is possible.
