4.3.2 Manual freshwater supply via external freshwater can (option)
If no house water connection with suitable water is available, you can manually supply water by filling a
freshwater can (option, volume: 20 liters / 0.71 cu.ft. You can attach the freshwater can on the rear of the
chamber or place it next to the chamber (chap. 19.9).
To guarantee humidification during 24 hours even at high humidity set-points with manual
water supply, we recommend filling the freshwater can (option) daily at the end of the day.
4.3.3 Connection kit for connecting the chamber to the water main
A safety kit against flooding caused by burst water hoses is enclosed with the constant climate chamber.
It consists of the following:
• Hose burst protection device
• 2 hose nozzles with screwing
• 4 hose clamps
• 6m water hose, divisible for the feed hose and drain
Protection principle of hose burst protection:
Whenever a strong water flow of about 18 l / min. occurs, e.g. caused by a burst water hose, a valve au-
tomatically cuts off the water supply, which can be heard as a clicking noise. The water supply now re-
mains shut until it is manually released.
Assembly:
Screw the hose burst protection device onto a water tap with a G¾ inch right turning thread connection.
The connection is self-sealing. Establish the connection between the safety kit and the chamber with a
part of the supplied hose. Protect both ends of the hose by the supplied hose clamps.
We recommend connecting the hose as the last step in order to avoid twisting the hose while screwing on
the safety kit.
Open the water tap slowly in order to avoid actuating the hose burst protection device.

Release of the reflux protection device:
In case the burst protection device has interrupted the water supply, first find the reason and remove it as
necessary. Close the water tap. Release the valve by a half left-turn of the upper knurled part. You can
hear the release of the valve as a clicking noise. Tighten the burst protection device against the water tap
by a right turn. Open the water tap slowly afterwards.
