Commissioning
The air dehumidifier must have been properly installed and connected (refer to
chapter 5, from page 12) 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.
1. Connect the hot condition coupler of the power cable included in the delivery
to the socket on the air dehumidifier.
2. Connect the power cable to the power outlet.
3. Ensure that the water tank is installed in the air dehumidifier or a drain hose
(option) has been properly fitted and laid to a collecting vessel or an outlet.
4. Turn the hygrostat to position "I“ and switch the air dehumidifier on via the
"On / Off switch" (Fig. 5, item 1).
If the air dehumidifier has been correctly connected and the existing humidity
is higher than the set humidity value the air dehumidifier will start to work.
Operator control
1. Select the desired humidity on the hygrostat (Fig. 6) and switch the air
dehumidifier on via the On / Off switch (Fig. 5, item 1).
If the existing humidity is higher than the set value the air dehumidifier will
start to work. If the existing humidity is lower than the set value the air
dehumidifier will not start to work.
The On / Off switch lights when the air dehumidifier is switched on.
The fan can be operated at two speeds (Fig. 5, item 5).
During operation condensate is produced. This condensate can either be fed
directly to an outlet via the condensate drain hose or collected in the water tank.
When the water tank is full, it will actuate the rocker by its weight and the air
dehumidifier will switch off. The pilot lamp (Fig. 5, item 2) will light up.
2. Switch the On / Off switch on the air dehumidifier off and empty the water
tank. After re-inserting the water tank into the air dehumidifier switch the air
dehumidifier on again.
