Drain Line Connection - Pentair FOLEO 5800 XTR Installer Manual

4.5.7. Drain line connection

NOTE

Standard commercial practices are expressed here. Local codes may require changes to
the following suggestions. Check with local authorities before installing a system.
CAUTION
The drain line plastic elbow must always be hand-tighten without using the elbow as a lever.
CAUTION
The drain plastic elbow is not designed to support the weight of the tube. The tube has to
have its own support.
CAUTION
Do not overtighten the tube on the drain line plastic elbow.
If available, use a floor drain or sump drain, but it is also possible to use a sump pit, dry well, clothes
washer drain, laundry tube or sanitary sewer line with sink type trap.
The drain line should be as short as possible and the unit should not be more than 12.2 m from the
drain. Use an appropriate adapter fitting to connect a 12.7 mm (½") plastic tubing to the drain line
connection of the valve if the drain line is shorter than 6 m. Use a 19 mm (¾") tubing if the drain is
longer than 6 m or if the backwash flow rate is greater than 22.7 L/min.
Use appropriate fittings to connect the 19 mm (¾") tubing to the drain connection on the valve.
Where the drain line is elevated but empties into a drain below the level of the valve, form a 18 cm loop
at the far end of the line so that the bottom of the loop is level with the drain line connection. This will
provide an adequate siphon trap.
Where the drain empties into an overhead sewer line, a sink-type trap must be used.
Also select a firm hose that will not soften and collapse or shrink at high temperature, at suspension
points or at sharp bends. Clamp the drain line securely to a rigid surface to prevent it from moving
during regeneration.
