Operating weight is for the tower with the water level in the cold water basin at the overflow. 2. When the flow rate for units exceeds 25 l/s the quantity of the coil connections will be double. When the flow rate for -Q units exceeds 57 l/s, connections of ND200 will be used (1 x inlet; 1 x outlet). 3. Inlet and outlet connections are beveled for welding.. Standard make-up, drain and overflow connections are MPT. 5. Dimensional drawings show standard (right hand) arrangements. Left hand arrangements can be furnished by special order. 6. All -models will be shipped in two sections: upper and lower section. 7. -units have standard Low Noise Fans. For units with optional Whisper Quiet Fans, a W is added at the end of the model name.

More can be found at The recommended support arrangement for units consists of parallel I-beams running the full length of the unit, spaced as shown in the following drawing. Besides providing adequate support, the steel also serves to raise the unit above any solid foundation to ensure access to the bottom of the unit. To support units in an alternate steel support arrangement, consult your BAC Balticare Representative. Units with and without Sound Attenuation 1. Unit Outline, 2. Air Intake, 3. Mounting Holes,.

All support steel must be level at the top. 3. Beams must be selected in accordance with accepted structural practice. Maximum deflection of beam under unit see table.. If vibration isolation rails are to be used between the unit and supporting steel, be certain to allow for the length of the vibration rails when determining the length of the supporting steel, as vibration rail length and mounting hole locations may differ from those of the unit.
