38 Installation
– If the conduit length between the water conditioning unit and the central unit of the Condair DL exceeds
20 m, the supply conduit must be equipped with a suitable pressure damper (overow valve, surge
tank, etc.). Furthermore, the supply conduit must be properly fastened according to the regulations
– The RO water must meet the following requirements:
– Fully demineralised water from a reverse osmosis system
– Conductance of the supply water: 0.5 ... 15.0 µS/cm
– Working pressure at maximum humidication capacity: min. 3 bar
– Maximum admissible inlet temperature: 45 °C
– No additives (such as chlorine, disinfecting agents, ozone, etc.) , except such approved by
Condair.
– Max. germ count at the water inlet on the Condair DL: 100 cfu/ml
Water drain line
The drain hose (rubber hose 1m, included in the delivery) is feed into the central unit via the correspond-
ing feed through and connected to the water jet pump using the hose clamp supplied.
The drain hose is fed from the central unit with a constant downslope (min 2%) down into an open
tundish connected via a siphon to waste water line of the building. Prevent the drain hose from slipping
out of the tundish by fastening it with appropriate means right above the tundish (without reducing
the diameter of the hose).
Important: for hygiene reasons it is not allowed to guide the drain water hose into a drain pipe equipped
with a bore!
