COMMISSIONING / INSTALLATION
1.0. INSTALLATION / Connection (only be conducted by a qualified erson)
(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 se arator, which corres onds to the ca acity (full disconnection with
3mm contact clearance, near to the device and easily gettable);
- the electrical rotection is aligned to the nominal current.
- no (warm air) back ressure develo s;
- the device is not ositioned 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 su ly.
2.0. AIR SUPPLY
2.1. To rotect the device and heating element the minimum air volume must flow. Never exceed the max.
tem erature. (Measured at the hottest oint 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 equi ment.
2.2. Air heaters WITH electronics may only be su lied with su ly air u to a maximum of 50°C/122°F, air heaters
WITHOUT electronics with a maximum of 80°C/176°F (s ecial versions Ty e L62 and Ty e XL92 u to a maximum
of 100°C/212°F su ly air tem erature).
Exce tions are the air heaters PH62 and PH92, which can be su lied with tem eratures u to 180°C/356°F (see
technical data and s ecial designs)!
2.3. Pay attention at the direction of air flow!
Air heater Type XS20, P and PN10:
(as s ecial versions also the series S, M, L and XL)
Air heater Type XS21, S, M, L, XL and P :
(as s ecial versions also with com ressed air connection)
2.4. When using com ressed air, a ressure reduction
valve and an oil and water se aration unit must be
in the su ly.
2.5. The air flow can be adjusted by means of an air
flow regulator.
2.6. As an air su ly,
blowers should be used, as
o timum results can be achieved ( ay 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 roblem exists
(e.g. metal, electrically charged or dam dust)
s ecial 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 ressure-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 age 6 – 14).
3.3. Allow the blower to cool the unit after using.
!!! CAUTION: The device may NEVER be operated without air supply !!!
