  • Page 5 In case of damage or suspected damage, this must be specified on the shipping note by the recipient and countersigned by the forwarder. The recipient must relay the respective details directly to WOLF. Units may only be transported in their fitting position.
  • Page 6 The whole underside of the equipment frame must be in contact with the supporting surface; gaps underneath the frame are not permissible. WOLF base frames are supplied either pre-fitted to the unit or as separate modules (shipped in advance). Separately supplied base frames are supplied as individual sections and must be assembled, aligned and fixed to the installation surface on site, according to the instructions supplied with the base frame.
  • Page 7 Installation information Gigant For units with washers, a base frame or foundation base must be used for KG and KGW units, as the washer protrudes from the bottom of the unit. The required height of the base frame depends on the type of washer and will be separately specified during the design of the housing.
  • Page 8: Installation Information

    Installation information Gigant Unit connection The cubical unit sections are connected to one another with M8 screws. For this purpose, the cubes contain bore holes at respective locations. All small assembly parts and loosely supplied accessory are packed in a component fitted with an inspection door (preferably fan component).
  • Page 9 Installation information Gigant The joints between two unit cubes are covered, as far as possible, with a double frame capping section. In some instances, however, double frame capping sections cannot be used for design reasons. In these cases, single frame capping sections are used and the gap remaining on all sides, is covered with a plastic cover strip or a plastic sealing section.
  • Page 10 Installation information Gigant Piggyback units For piggyback units, where the top and bottom units are supplied separately, the units must be secured to each other on site. The manufacturer makes provisions for the connections to be made with self- tapping screws. The required number of self-tapping screws are supplied with the air-conditioning unit.
  • Page 11 Installation information Gigant The fan shaft must remain horizontal at all times. Fan section Caution Remove transportation fastening from fans seated on anti-vibration struts. Transportation fastening Remove transportation fastening. Canvas couplers When installing, it should be noted that the gap between the connecting flanges is permitted to be up to 100 mm, thus enabling full movement of the canvas couplers.
  • Page 12 It is not permissible to join several drain sections onto a common drain trap. WOLF supplies the drain trap as an accessory. The required drain trap height must, in this case, be determined on site. If the drain trap is provided by the customer, the drain trap height must be determined according to the adjacent illustration.
  • Page 13 Electrical connection Gigant Electrical connection The electrical connection may only be carried out by a qualified electrician in accordance with the valid regulations (VDE, EVU, etc.)! In case of switch-off or breakdown o the supply or exhaust fan, all control valves, the warm/cold water and the washer pump must be shut off automatically! Only use control valves which are closed, when contact is interrupted, and frost protection thermostats without reclosure preventing...
