1 It is critical that these systems receive water virtually free from sediment and these constituents. Make certain that water is properly filtered and preferably softened before it enters these systems. IMPORTANT: Each system should have an in-line flow control installed after the unit to restrict service flow rate.
2 Capacity varies by unit and should be calculated.
