Operation and Maintenance Instructions
Recirculated Water System – Routine Maintenance
Suction Strainer in Cold Water Basin
The pan strainer should be removed and cleaned monthly or as often as necessary. The suction strainer is the first line of defense
in keeping debris out of the system. Make certain that the strainer is properly located over the pump suction, alongside the anti-
vortexing hood.
Cold Water Basin
The cold water basin should be flushed out quarterly, and checked monthly or more often if necessary, to remove any accumulation
of dirt or sediment which normally collects in the basin. Sediment can become corrosive and cause deterioration of basin materials.
When flushing the basin, it is important to keep the suction strainers in place to prevent any sediment from entering the system.
After the basin has been cleaned, the strainers should be removed and cleaned before refilling the basin with fresh water.
Operating Level of Water in Cold Water Basin
The operating level should be checked monthly to make sure the water level is correct. Refer to Table 3 for unit specific levels.
