4. Installation and connections
4.1 Water supply
Freshwater is supplied by manually filling a freshwater can. It is not possible to connect the chamber directly
to a water pipe.
The freshwater can has a volume of 10 liters /
0.36 cu.ft.
and will be placed inside a water can support.
To guarantee humidification during 24 hours even at high humidity set-points, we recommend
filling the freshwater can daily at the end of the day.
When the freshwater can is empty, the message “Freshwater supply” will be displayed on the controller
(chap. 13.1), the buzzer sounds, and the humidification module turns off. After acknowledging the alarm,
the humidification module tries to fill up and start operating.
Emerging condensation water is collected in a collection pan below the chamber.
Regularly check the filling level of the condensate collection pan. Bringing a source of humidity
into the inner chamber may increase wastewater production.
Water consumption: The maximum is 1 liter per day. At 40 °C and 75 % r.h. without door opening: approx.
100 ml per day.
4.1.1 Types of suitable water quality
•
Deionized water from a water treatment installation already existing at the customer's site. Conductivity
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).
•
Tap water that has been treated by the optional water treatment system BINDER Pure Aqua Service
(disposable system). A reusable measuring equipment to assess the water quality is included (chap.
4.1.2).
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.
NOTICE
Danger of calcification of the humidifying system.
Damage to the chamber.

Operate the chamber with deionized (demineralized) water only.
Water intake temperature NOT below +5 °C /
41 °F
and not exceeding 40 °C /
104 °F
.
4.1.2 BINDER Pure Aqua Service (option)
The optional BINDER water treatment system (disposable system) is available to treat tap water. The life-
time depends on water quality and the amount of treated water used. The measuring equipment to assess
the water quality is reusable.
