3-5 Making Tank Piping Connections
If you have purchased the SCW Series central chilling station with the integral pump tank, please proceed with this section.
Return
Bring the chilled water returning from the process to the pump tank warm From Process side. This line is sized according to the flow rate from the process to the pump tank. See Section
Important!
Do not use the SCW Series unit to support piping.
Makeup
Connect a city water source to maintain water level in the pump tank.
Overflow
Connect the OVERFLOW outlet to an approved, trapped drain to permit excess water in the pump tank to overflow to the drain. The overflow line is sized according to the size of the pump tank.
To Drain
Connect to a 1½” line (approx. 63 mm) leading to an approved, trapped drain. You can drain the pump tank if necessary.
