Water-quality information:
– Use only fresh drinking water to supply the appliance. It is not permissible
to supply the appliance with water from open water courses,
because of the high germ count (microorganisms).
– We recommend the use of a demineralization system, (e.g. a reverseosmosis
system) when the water is very hard (mineral-rich).
Caution! Fully demineralized water (VE water) from a reverseosmosis
system is aggressive. In this case all lines and connectors of
the water installation (supply and drain) must be made of stainless steel
(minimum requirements according to DIN 1.4301) or plastic.
Note: Base exchangers (water softeners) are not suitable for watertreatment
purposes because they do not reduce the quantity of minerals
dissolved in the water. Phosphate cartridges are also unsuitable because
they increase the minerals dissolved in the water.
– Do not add disinfectants to the water. These are discharged into the
ambient air during the atomization process and may cause mucousmembrane
irritation or allergies.
Please consult your Defensor dealer if you have questions concerning
water treatment.
Water drain line
Basic units SU11 and DU11 with automatic flushing
Via a siphon trap, connect the drain of the basic unit (inner Ø= 40mm)
to a drain line of the building (inner Ø >40mm). Use rigid plastic pipe
(min. inner Ø= 37mm) for the connection and route the pipe with a
downward pitch of at least 10°. To ensure that the entire reservoir
content can be discharged when the appliance is emptied, the connecting
pipe should not be shorter than:
– for the SU11 base unit: about 1m – for DU11 base unit: about 2m Use a hose clip on the drain connection to fasten the installed line.
Notes:
– It is advisable to use steel piping (min. requirements according to
DIN 1.4301 if VE-water is used) for the drain line in exposed locations.
– For safety reasons, do not use flexible tubing for the drain line.
Base units SU21 and DU21 with automatic level security device
The drain connections on base units SU21 and DU21 are closed with a
drain pipe with a threaded cap. The drain cap is not installed when the
appliance is delivered. To install the drain pipe, proceed as follows:
• Insert the drain pipe into the drain connection until it comes to a stop,
then secure it with the hose clip.
