OPERATING MANUAL
Hot-Air Blower COMPACT
SAFETY
Danger to life when opening the tool, as live components and connec-
tions are exposed. The device must be disconnected from the mains sup-
ply before opening. Electric work shall only be operated by qualified
personal (according to TRBS 1203).
Danger of fire and explosion if the hot air blower is installed and used
incorrectly, particularly near flammable materials and explosive gases.
Not suitable for hazardous locations! The minimal air flow must not be
undercut.
Danger of burns
Do not touch heating element pipes and nozzles 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. Tools with a fix connection must be connected to a
separator (e.g. mains switch).
Special connecting conditions ac-
cording to IEC/EN 61000-3-11;
Zmax = 0,039Ω+ j 0,025Ωfor short
time rating (30 minutes);
Zmax = 0,026Ω+ j 0,016Ωfor con-
tinous operation.
Consult your local electricity supplier if necessary.
GFCI/RCCB: for personal protection on building sites we strongly rec-
ommend to connect the tool to a GFCI (Ground Fault Circuit Interrupter)
or to a RCCB (Residual Current Circuit Breaker).
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 LIABILTY
Warranty and liability apply from the date of purchase (documented by the in-
voice/delivery note) according to the currently valid general terms of business
from BAK. BAK refuses to honour any warranty for devices which are not in
their original condition. BAK devices may never be reconfigured and/or modified.
BAK reserves the right to deny any responsibility if this is ignored. No liability
can be assumed by BAK for incorrect installation and/or use as well as natural
wear and tear of components (e.g. heating elements).
Note:
This operating manual must be available to the installation and operating person-
nel at all times. Read these operating instructions carefully before installing and
using the device.

CONVENTIONAL APPLICATION
This BAK hot air heater is a modular unit which creates process heat in industrial
environments. The device is suitable for continuous operation. The blower can be
used as hand tool, bench tool or can be built into machines and installations.
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 (MRL) must be guaranteed.

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. Connection for model 400VAC:
- L1 = black
- L2 = brown
-N = blue
1.2. When installing the tool, ensure that:
- the electrical protection is aligned to the nominal current.
- only cold air up to a max. of 50°C / 122°F is fed to the device.
- no (warm air) back pressure develops.
- the air intake (9) is not covered and the tool can take in the air with
no problems.
- the device is not positioned within the hot air jet of a different device.
1.3. When built in vertical (Blow off opening downwards) it is important that
the device cannot suck in hot air.
1.4. Protect the device from vibration and shock. For mechanical movements
use absorber against the impacts.
1.5. When fixing, the thread inserts M5 (11) on the underside of the device
should be used.
1.6. At high foaling of the intake air (e.g. textile factory) a BAK-stainless steel
filter should be used.
2.0. OPERATION
2.1. Make sure that the hot air can flow freely. Warmth backflow can occur
damage on the device (risk of fire!).
2.2. Allow the blower to cool the unit after using.
STANDARD DESIGN
The hot air blower is equipped with a control electronic to control the temperature
and the speed level. It is also provided with a built-in potentiometer as well as an
integrated heating element and device protection.
