Page 6: Notes On Installation
Notes on installation Foundation Install the units and components on a surface which is smooth, level and of Caution adequate load-bearing strength. The base frames must be horizontal and the foundations must be smooth-topped KG 40-250: and horizontal. Make sure that the bottom of the frame is in full-face contact with the supporting surface: spot support is not permissible. - Page 7 Notes on installation Base frames are either secured to the unit or delivered separately (in advance). Base frames delivered in advance are in sections and must be assembled on site in accordance with the instructions enclosed with the shipment, then aligned and secured to the supporting surface.
- Page 8 Notes on installation Securing the sections Sections with angle-section frames (KG 40-250) are secured by means of M6 threaded fasteners and clip spacers. Sections with square-section tubular frames (KG/KGW 630-1000) require M12 bolts. The cubes have pre-drilled holes to accommodate the threaded fasteners. All the small items required for assembly are shipped along with the accessories packed inside a section with an inspection door (usually the fan section).
- Page 9 Notes on installation Configurations: Sections for stacked configurations are delivered to site separately and must be stacked or side-by-side secured together on site with the aid of the enclosed self-tapping screws (KG 40- 250) or enclosed accessories (KG/KGW 630-1000). The sections which make up the stacked or side-by-side configuration cannot be secured together until the various transportable units have been installed on site in their final positions.
- Page 10 Notes on installation KGW roof The weatherproofed KGW 630-1000 air-coinditioning units have a UV-resistant, weatherproof skinned roof. Fully assembled units are supplied complete with the roof pre-installed. Each section of a sectionalized unit has its own roof; the butt joints in the roof must be sealed on site once the sections are installed.
- Page 11 Notes on installation Fan section The fan shaft must always be horizontal. Caution Remember to remove the transportation locking devices of fans mounted on vibration damper springs. Locking When installing, bear in mind that the maximum permissible distance between the devices connecting flanges is 100 mm, in order to ensure that the sailcloth adapter has full freedom of movement.
