4.1 Wastewater connection for humidifying system
Fasten the wastewater hose to the wastewater connection “OUT” (17) (Figure 8) on the rear of the unit
(olive ∅ 14 mm). Observe the following points:
•
You can use a part of the supplied tap water hose as a drainage hose. In case another hose is used, it
has to be permanently resistant against at least 95 °C / 203 °F.
• Mount the wastewater hose with a maximum positive inclination of 1 m and a maximum total length of
3 m.
• Protect both ends of the drainage hose with two of the four supplied hose clamps.
Wastewater is collected in an internal can with a volume of approx. 0.5 liters. It is pumped off
only when required, thus there is no continuous wastewater flow.
Protect the wastewater supply at both sides with the supplied hose clamps.
4.2 Freshwater supply for humidifying system
Connect the wastewater pipe before connecting the unit to a freshwater pipe or filling the wa-
ter can.
You can supply the unit with freshwater via a water pipe or by manually filling the internal water can. It is
not necessary to switch between both possibilities. When connecting to a water pipe, the water can is
automatically filled.
Water intake temperature NOT below +5 °C / 41 °F and not exceeding 40 °C / 104 °F.
CAUTION
Calcification of the humidifying system.
Damage to the unit.

Operate the unit with deionized (demineralized) water only.
Types of suitable water quality
•
Deionized water from a water treatment installation already existing at the customer's site. Conductivi-
ty from 1 µS /cm up to a maximum of 20 µS/cm. (Water, which is in equilibrium with the CO
2
in the air,
and has a conductivity below 1 µS/cm (ultrapure water), may cause acid corrosion due to its low pH.)
• Water treated by the optional water treatment system BINDER Pure Aqua Service (disposable sys-
tem). A reusable measuring equipment to assess the water quality is included (chap. 16.6).
BINDER GmbH is NOT responsible for the water quality at the user’s site.
Any problems and malfunctions that might arise following use of water of deviating quality is
excluded from liability by BINDER GmbH.
The warranty becomes void in the event of use of water of deviating quality.
