Assembly of Bottom Inlet Piping
On the ATLAS tower, the inlet connection is located on the bottom as standard. Internal piping is provided that allows the process
water to make its way to the hot water distribution system. Please follow the below steps to complete field installation of the bottom
inlet after the unit is rigged.
1. On the ATLAS tower, the inlet connection is located on the bottom as standard.
2. Locate the bottom inlet assembly components, namely the riser pipes, two flexible reinforced pipe connectors per basin, four
pipe clamps per basin and the lower pipe flanged spool. These components are fastened securely in the unit’s basin prior to
shipment.
2a. Remove shipping strap under pipe.
3. Align the riser pipe assembly with the upper pipe section in the bottom of the casing section. Loosen the pipe clamp and slip
the pipe connector up over the upper pipe section.
4. Tighten all pipe clamps (4 per basin: 2 on the upper). A ratchet wrench is recommended (See Figure 7).
5. Repeat this process for each riser pipe.
6. After tower is fully installed, insert the lower pipe flanged spool with gaskets between flanges, as shown in Figure 8. Use
hardware noted in Table 2
