OPERATING MANUAL
Air heater Type XS, S, M, L, XL, PN10
1
SAFETY
Danger to life when opening the air heater, as live components and connections are
exposed. The device must be fully disconnected from the mains before opening. Electric
work shall only be operated by qualified personal (according to T BS 1203).
Risk of fire and explosion if air heaters are installed and used incorrectly, particularly
near flammable materials and explosive gases. Not suitable for hazardous locatio s!
The minimal air flow must not be undercut.
Risk of burns! Do not touch heating element pipes and nozzles used when hot. Let the
device cool down. Do not point the hot air jet at persons or animals.
The mains voltage specified on the device's type plate must correspond to the mains
voltage. Air heaters with a fix connection must be connected to a separator ( e.g. mains
switch).
Special connecting conditions Zmax = 0.039 Ω + j 0.025 Ω for short time rating (30 min.)
according to IEC/EN 61000-3-11; Zmax = 0.026 Ω + j 0.016 Ω for continuous operation
Consult your local electricity board if necessary.
Device in protection class I should be earthed using a protective conductor
Device in protection class II
The device must be supervised when in operation. The heat can reach flammable
materials that are out of view.
Protect the device from damp and wet!
WARRANTY AND LIABILITY
Warranty and liability apply from the date of purchase (documented by the invoice/delivery note)
according to the currently valid general terms of business of BAK AG.
BAK refuses any warranty for devices that are not in their original condition.
No liability can be assumed by BAK for incorrect installation and/or use as well as natural wear and
tear of the device (e.g. heating elements).
BAK – devices may never be converted and/or modified.
BAK reserves the right to deny any responsibility if this is ignored.
Note:
This operating manual must be available to the installing and operating personnel at all times. Please
read this operating manual carefully before installing and commissioning the device.

CONVENTIONAL APPLICATION
Air heaters are modular units which create process heat in industrial environments.
Their installation and the working process shall only occur after observance of every safety
arrangement for the provided place of installation and application. The accordance with the effective
edition of the equipment and operations safety (GPSG) and the machine standards (M L) must be
guaranteed.
The air production, which is necessary for the application, shall be produced by an appropriate
BAK blower.
INSTALLATION
1.0. INSTALLATION / Connection (only be conducted by a qualified person)
(thermal security class 1 according to EN 60519-1, paragraph 13.8)
1.1. When installing the tool, ensure that:
- the electric connection directs above a separator, which corresponds to the capacity
(full disconnection with 3mm contact clearance, near to the device and easily
gettable);
- the electrical protection is aligned to the nominal current.
- no (warm air) back pressure develops;
- the device is not positioned within the hot air jet of a different device .
1.2. Protect the device from vibration and shock! Use absorbability at mechanical motion.
2.0. AIR SUPPLY
2.1. To protect the device and heating element the minimum air volume must flow. Never exceed
the max. temperature. (Measured at the hottest point 3mm from the air outlet)
The heater must be switched off, if the inlet air falls below the minimum. This function should
be included into the safety circuit of the equipment.
2.2. The max. temperature of the inlet air for the air heater may not exceed 50°C / 122 °F.
2.3. Pay attention at the direction of air flow!
Air heater Type XS a d PN10: Air heater Type S, M, L a d XL:
2.4. When using compressed air, a
pressure reduction valve and an oil
and water separation unit must be in
the supply.
2.5. The air flow can be adjusted by
means of an air flow regulator.
2.4. Use BAK blowers for air supply (pay attention at
the direction of rotation and the electrical
connection).
2.5. For use in a dusty environment clean the filter of
the blows regularly. When a critical dust
problem exists (e.g. metal, electrically charged
or damp dust) special filters must be used to
avoid short circuiting in the tool.
3.0. OPERATION
3.1. Make sure that the hot air can flow freely. Warmth backflow can occur damage on the
device (risk of fire!).
3.2. CAUTION: Pay attention to the minimum air volumes according to the technical data.
3.3.
Allow the blower to cool the unit after using .
C UTION: The device may NEVER be operated without air supply!!!

Note for type L/XL:
After activating the tool protection trips, the air heater switches the power stack off. The build-in relais
delivers a dry change-over contact at the clamps 1-3 (see connection diagram). A restart of the power
stack is only possible after a reset (disconnection of the tool from the mains power).
Measures whe activati g the heati g eleme t or tool protectio trips:
Disconnect the device from the mains power, after 3 seconds the device restarts automatically. Check
air supply (air pressure, flow and filter), reconnect the device to the mains power.
