Installer Manual Evolio 255 - Installation
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.
NOTE
Plumbing codes do not allow a direct connection into any sanitary or storm drain, sewer line
or trap. Waste connections or the drain outlet shall be designed and constructed to provide
connection to the sanitary waste system through an air-gap of at least 5 cm This is usually
required so sewer backup will not be back-siphoned into the softener.
CAUTION
When running the drain line to a floor drain, the area around the drain may become wet
during the regeneration process. Keep floor drain area clean at all times to prevent any
damage.
