2 or 4-pipe system Five types of configurations are available, defined according to the position of the primary air connection with regard to the water connections (with the water connection viewed from the front), namely: 1. Lateral primary air connection on left side, (-LI) type 2. Lateral primary air connection on right side, (-LD) type 3. Primary air connection at top, (-S) type The 900 to 1800 sizes are manufactured with one primary air connection inlet. The beam width measurement (595) listed corresponds to the ceiling-mounted design using a T-section with a width of 25 mm. For...
