4.5 Water supply for the chamber with active humidification
Freshwater is supplied by manually filling the freshwater bag. It is not possible to connect the chamber
directly to a water pipe.
The freshwater bag has a volume of 0.9 liters / 0.32 cu.ft. and is placed behind the chamber door in a
recess.
To guarantee humidification during 24 hours even at high humidity set-points, we recommend
filling the freshwater bag daily at the end of the day.
When the freshwater can is empty, the message “Freshwater supply” will be displayed on the controller,
the buzzer sounds, and the humidification module turns off. After acknowledging the alarm, the
humidification module tries to fill up and start operating.
Water consumption at 37 °C / 98.6 °F and 93 % r.h.:
•
Without opening the door: very low.
•
When opening the door 10 times a day: approx. 70 ml per day.
4.5.1 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.
4.5.3).
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.
CAUTION
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 .
