After receipt of the laser check if all parts are there and inform IPG immediately for missing or damaged part. In case of any supposed or apparent damage, do not try to install or run the laser. Keep the package for later transport or storage of the device. The transport of the laser happens on a euro-pallet with help of a forklift. On the upside of the laser transport eyes are fixed. With lifting equipment the laser can be lifted from the pallet. The laser can be moved with casters. Transport without the euro-pallet is not permitted. The Laser can be moved with fixable casters to the final place of installation if the subfont is appropriate to it. The laser must become brought in such a position that doors and side panels can be reached for service. The length of supply and control lines must be arranged in a way that laser can be moved 1m. The supply and control lines should be passed in order not to snap off. At laser installation in the laser cabin the general health and safety regulation of the operator have to be followed. The casters at the bottom side of the laser cabinet have to be fixed at the place of final installation. A rugged installation has to be assured. Consider the weights at higher places of installation. If needed laser and chiller has to be equipped with appropriate intercepting tanks against leaking water. The laser is lockable and should be secured after work against unauthorized use. The seal of the external cabinet secures power supply and laser modules against environmental dust. The in the laser cabinet (power supply) produced waste heat becomes derived trough installation of an internal heat exchanger. Thereby water chilled lasers do not need an additional fan.
