Leister LE 5000 DF [12/16] Air supply

Device description

• The device may only be installed by trained personnel

• The installation must ensure that

– no excess (heat) residue builds up

– the device is not subject to jets of hot air from another device

• Protect the device from mechanical vibrations and shocks

• For installation dimensions, see pages 3, 4 (Size)

• As air supply, suitable blowers have to be used (pay attention to the direction of rotation).

• In order to protect the heating element, the specified minimum air volume must never be fallen below and the

maximum temperature (hottest point measured 3 mm in front of the heating element tube) must never be exceeded

(see technical data). If the minimum air volume is fallen below, the heat output must be interrupted immediately.

• Air Heater type DF may only be supplied with air up to max. 160 °C / 320 °F.

• Observe direction of air flow.

• For use in a dusty environment the tool should be fitted with a Leister stainless steel filter on the air intake

connection. Where a particularly critical dust problem exists (e.g. metal, electrically charged or damp dust)

special filters must be used to avoid short circuiting the tool.

• The air heater must be connected by qualified personnel.

• A suitable device for full disconnection from the mains with a contact distance of 3 mm must be provided in

the mains connection.

• The power supply cord should have the corresponding cross section area of conductor and should be fitted by a

specialist.

• The device must be connected in accordance with the connection on page 5 (Wiring Diagram) of the operating

instructions.

• Only the installed temperature-resistant special cord may be used for the electrical connection.

• It must be ensured that the power supply cord is protected against mechanical strain when routing it.

• It must be ensured that the connection lines do not come into contact with the heating element tube and are not

exposed to the hot air jet.

• Connect air heater to the electrical mains.

• It must be ensured that the hot air can flow out freely, as otherwise the device can be damaged by the excess

heat building up (risk of fire!).

• Attention: comply with minimum air volume and maximum air temperature as per technical data.

• Switch on mains.

• Allow device to cool down after heating mode.
