• In order to protect the device and 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 specifications). If the minimum air volume is fallen below, the heat output must
be interrupted immediately.
• Observe direction of air flow.
• Leister blowers must be used as an air supply (observe direction of rotation and compression preheating).
• When operating with compressed air, the maximum air pressure must not be exceeded (see technical specification)
• If the air contains dust, use a Leister stainless steel filter on the blower air intake. In the case of particularly
hazardous dusts (e.g. metal, electrically conductive or damp dusts), special filters must be used to avoid
short-circuits in the device.
• The LHS air heater must be connected by qualified personnel.
• A suitable device for full disconnection from the mains must be provided in the mains connection!
• 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.
• The device must be connected in accordance with the connection diagram and the terminal arrangement
on pages 7, 8, 9, 10 (Wiring Diagram) and page 11 (Interface) of the operating instructions:
– Carry out wiring in the
connection housing (2)
.
•
ATTENTION:
check dip switch settings of the LHS SYSTEM air heater (see chapter Operation).
• Mount
connection housing cover (2)
with the
screws (3).
• Connect LHS air heater to the electrical mains.
• Mount corresponding nozzle, if required.
• 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 as per technical data.
• Switch on mains.
• Allow device to cool down after heating mode.
LHS CLASSIC
• For operation with permanent maximum heat output (must be adapted to the air volume supply)
• For operation with external power control (for example with semiconductor relay, SSR).
• Note:
– Different wiring requirements for working with SSR or without . See wiring diagramm page 7 and page 9.
– The device must be disconnected from the mains via a suitable external circuit if the overheating detection is
activated.
LHS PREMIUM
• Infinitely adjustable heat output via red potentiometer on the device.
• The device is fitted with an integrated heating element and device protection).
