OPERATION AND OPERATOR CONTROL
Continuous adjustment of the hygrostat allows for easy humidity control. If very
precise setting values are required, use a hygrometer with a precise humidity
display to set the hygrostat.
Please note:
By using a condensation dryer humidity values of 40 – 45% r. h. minimum can be
reached. If lower values are required an adsorption dryer must be used.
Contact your technical advisor.
Comfortable ambient climate:
For living space, climate conditions of 20 – 25 °C and 50 – 60% r. h. are
recommended. For quick building drying the hygrostat is set to continuous
operation (Max pos.). For drying and keeping rooms with wood furnishing (e.
g. parquet flooring) or paintings, antiques etc. dry, a minimum humidity of 55
– 60% must be observed.
In case of doubt please contact your technical advisor.
External humidity control (optional):
Optionally the AD 7 series is available with connection facility for external On/Off
control, for example via a dew point sensor or an external hygrostat.
In this case the appliance will be equipped with our SensorLogic providing a
potential-free contact and a supply voltage of 24 V.
Instead of the hygrostat, an Amphenol socket is arranged in the operating panel.
With the suitable Amphenol connector (accessory) your external control can be
easily connected.
Commissioning
The air dehumidifier must have been properly installed and connected before it
can be commissioned.
Before commissioning the air dehumidifier allow it to rest in its
final position for about 15 minutes after transport. During this
time, the oil distributed in the cooling system and churned up by
transport will flow back to the compressor. This procedure will
extend the service life of the compressor.
