COMMISSIONING / INSTALLATION
1.0.
INSTALLATION
/
Connection (only be conducted by a
qualified person)
(thermal security class 1 according to EN 60519-1, paragraph 10.6)
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! At mechanical movements
damping must be used
.
1.3.
Decommissioning:
De-energize the device, disconnect the mains supply.
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.
Air heaters WITH electronics may only be supplied with supply air up to a maximum of 50°C/122°F, air heaters
WITHOUT electronics with a maximum of 80°C/176°F (special versions Type L62 and Type XL92 up to a maximum
of 100°C/212°F supply air temperature).
Exceptions are the air heaters PH62 and PH92, which can be supplied with temperatures up to 180°C/356°F (see
technical data and special designs)!
2.3.
Pay attention at the direction of air flow!
Air heater Type XS20, PH and PN10:
(as special versions also the series S, M, L and XL)
Air heater Type XS21, S, M, L, XL and PH:
(as special versions also with compressed air connection)
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.
2.6. As an air supply,
HERZ
blowers should be used, as
optimum results can be achieved (pay attention at
the direction of rotation and the electrical
connection).
2.7. 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.
2.8. The air flow can be adjusted by means of an air flow
regulator.
NOTE:
The air heaters of the series XS21, S, M, L and XL are
NOT
pressure-resistant!!!
3. 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 (see page 6 – 14).
3.3.
Allow the blower to cool the unit after using.
!!! CAUTION: The device may NEVER be operated without air supply !!!
