Installation information Foundation A level, horizontal and load-bearing surface is required to site and install the Please note units and unit components. Base frames must be levelled horizontally; foundation plinths must also be KG 40-100: level and horizontal. The entire lower unit frame must sit on the foundation; point loads are not permissible. - Page 7 Installation information KG 15-100 Sealing tape KG 40-100 Only with recirculation air damper with self-tapping hexagon screws Ø 8x25 Sealing tape Unit arrangement: Stacked units are delivered separately and must be linked together on site stacked or adjacent using the unit connectors and drilling screws provided. Upper and lower or adjacent unit sections cannot be fitted together until the various transport units have been assembled at the final installation site.
- Page 8 Installation information Version for disassembly The units are delivered fully assembled. To facilitate handling, they can be (on request) taken apart and reassembled in the installation room. KG 40-100 With the version for disassembly, the frame sections split in the centre and are secured with a flat steel bar or angle bracket (secured with screws).
- Page 9 Installation information On-site cooler installation: Remove casing and mist eliminator with condensate pan (mist eliminator is placed in the guide rails for shipping). Apply sealant to the mist eliminator frame and secure to the cooler bank. Please note The condensate drain apertures in the mist eliminator must be facing downwards. Direction of air flow Depending on the direction of the air flow, the removable cover panel must be fitted at the air intake on the collector side of the cooler bank.
- Page 10 Installation information Ball siphon In order to drain away the condensate reliably, join a ball siphon to the condensate drain connector onto the drain pan for the cooler/direct evaporator and onto the KGX/KGXD plate heat exchanger pan. Please note that a siphon must be fitted to every condensate drain connector. It is not permissible to join several drains to a common siphon.

Page 14: Commissioning
Commissioning In accordance with DIN EN 1886, the unit must be opened with tools. Wait for the fan to come to a complete standstill before opening the inspection doors. When the doors are opened, negative pressure may draw in loose objects, which could destroy the fan or even cause a risk to life if items of clothing are drawn in. - Page 15 Commissioning Louvre damper The louvre dampers may need to be insulated on site against both sound (accessory) emission and the formation of condensate. In the case of louvre dampers, follow the separately supplied installation instructions for the damper servomotor. Louvre damper drive shaft: 15 x 15 mm If louvre dampers are located on the pressure side, open them fully before commissioning the fan.
