Issue:
Should I use inlet water strainers on an open loop system?
Resolution:
Inlet water strainers are required for all inlet pipe connections. Clean out tees should be included to prevent disturbance in waterflow.
Per the IOM to prevent evaporator damage, pipe strainers must be installed in the water supplies to protect components from water borne debris. Trane is not responsible for equipment-only-damage caused by water borne debris. The field needs to furnish and install strainers ahead of all pump and automatic modulation valves and at the inlet of the evaporator.
Failure to provide proper barrel protection may and can result in warranties being voided.
