KL 1500 HAL / KL 1500 H - Operating instructions
The KL 1500 HAL emits high intensity visible light. As light absorbing materials have the physical
property of converting incident light into heat, damage may occur to heat sensitive or flammable
light absorbing materials. To avoid such thermal damage and the potential danger of fire or burns,
please adhere to the following instructions:
 Never cover up the light guide exit (danger of fire!)
 Never cover up the open of the light guide exit with your hands or other parts of your body
(danger of burns!)
 When illuminating heat sensitive or flammable light absorbing objects (e.g. in microscopy),
special care must be taken to keep an appropriate distance between the light guide and object.
Also to select a suitable lamp brightness level in order to avoid thermal damage to the object.
 When the light source is switched on, all light guide exists not being used in the working
procedure must always be a safe distance – at least 10 cm – away from heat sensitive or
flammable light absorbing materials (prevention of possible fire hazard). Care must therefore be
taken that each light guide exit is at the above mentioned safe distance away, for example:
dark/coloured textiles and dark/coloured wooden or plastic surfaces.
 To avoid unnecessary strain on biological tissue by illuminating with visible light, reduce the
brightness and duration of illumination to the absolute minimum level required.
 Ensure a safe earthing connection when connecting the device
Please make sure that
 your KL 1500 HAL cold light source is operated at the voltage stated on the model plate (13);
 all air vents (11, 12) are kept clear at all times. In the event of insufficient cooling, an
integrated thermo switch will cut off the instrument temporarily (see Point 5 "Troubleshooting")
 the lamp has cooled off before being replaced. A warning sign has been attached in the door
of the lamp compartment to remind you of this necessity:
(warning of hot surface)
 the filter slide and insert filter have cooled off before the insert filter is removed. The slide is
marked with a warning sign
 the filter slide is always locked in place during the operation of the light source (see Point 2.6
"Filter slide"!)
 the light guide is cooled off before being replaced.
 The light source has been developed for operation in dry rooms only! (see Point 7 "Technical
data").
 The instrument must not be used in explosive areas.
 Safe disconnection from the power supply is only guaranteed by pulling out the mains plug.
 The instrument may neither be opened nor dismantled. Technical modifications are forbidden.
Repairs must only be carried out by the manufacturer or by its authorised customer service
agencies.
 Please ensure that every user of the system has quick access to these operating instructions.
 The manufacturer is not liable for damage caused by failure to obey these instructions.
