Observe the following points when using the direct steam humidifica-
tion:
The direct steam humidification only works actively in one direc-
tion. It only humidifies; it does not dehumidify.
The direct steam humidification is optimised for operation at
temperatures up to 40 °C.
If the direct steam humidification is used in combination with
the LED illumination, the heat radiating from the LEDs can result
in the desired humidity not being reached. In addition, there can
be significant condensation in the incubation chamber.
The
Temperature
parameter must be activated.
4.2.2
Connection Conditions
To commission the direct steam humidification, it must be connected
to an unpressurised water tank or to a pressurised water supply. The
inlet pressure must not exceed 0.3 bar.
The connection for water supply for the direct steam humidification is
located at the bottom of the casing and is designed for hoses with a
diameter of 6 to 7 mm.
ATTENTION
Using tap water can quickly lead to limescale in the vaporiser of
the humidification unit, which would affect correct functioning.
Ultra pure water (WFI, water for injection purposes) must not be
used either as this is highly corrosive and thus damages the device.
Adding detergents, disinfectants or similar chemicals to the water
for the direct steam humidification can damage the device. Only
use water without additions, in accordance to the specification
(see chapter 12.5.3 "Direct Steam Humidification", page 148).
