Controller for desired air humidity
The desired level of humidity in the room can be regu-
lated by using the control switch (2). A higher num-
ber increases the dehumidification level of the air. This
means that a dehumidification level of approx. 95% rela-
tive humidity will typically result at setting '1' (always
dependent on ambient conditions!), approx. 35% rela-
tive humidity can typically be attained at setting '5' and
dehumidification will continue at "Cont" position without
a shut down by the hygrostat (with interruption during
"Defrost" mode). The "OFF" setting means that the con-
tact of the moisture meter is open and that the device is
not operational.
CAUTION:

Whenever the power plug is connected the electrical
components in the device are live.
What should I do if the dehumidifier does not switch on or does not dehumidify?
First, make sure that the red "POWER" control light is switched on. This indicates that the device is being supplied with
power; otherwise check to see if the power plug has been plugged in correctly and whether the socket itself is actually
being supplied with power. Make sure that the green "FULL" control light is switched off. If this is not the case, check
whether the container is full or the rocker switch on which the tank is located is blocked by foreign bodies.
Check whether the red "WORKING" control light lights up, which means that operation is required by the moisture
meter (hygrostat Figure 2).
If the device switches back on after a break (because the desired humidity level has been reached or if the canister has
been emptied), the red "DEFROST" control light lights up in addition to the "Working" control light. During this defro-
sting phase, which lasts approximately 5 minutes, only the fan is operational; the compressor itself is shut down. This
cycle is repeated once approximately every 45 minutes in order to enable defrosting of the evaporator.
If the device is operating normally and the two middle red control lights for "Power" and "Working" are illuminated but
only a little or even no water is given off, check whether the relative room air humidity is less than 40 - 45 %.
If the red "DEFROST" control light illuminates, the defrosting phase is in operation.
The hot gas defrost function works as follows: every 45 minutes the compressor shuts down for 5 minutes (while the
fan remains in operation). After this period has lapsed the compressor switches back on again. A drop in temperature
below 0° C is registered by a temperature sensor; in such a case the electronic circuit board activates a solenoid val-
ve in the refrigeration circuit so that the path of the refrigerant and the hot gas now flows via the evaporator, thereby
melting the ice. When the temperature of the evaporator increases, the defrost process is ended and the valve switches
back to its original position. The fan is switched off during this process.
Condensate drain port
The High-Dry 650 can be connected directly to a flexible drain hose. Remove the canister for this. The ¾" hose con-
necting piece is located above the position of the canister inlet opening. Fasten a standard hose connecting piece with
¾" female thread (e.g. GARDENA or GEKA - not in scope of supply) for this. The hose can be passed outwardly
through a hole that is located in the base of the device.
ATTENTION: Please note that the drain hose should be laid at ground level without any kinks and that the
outlet end is always located deeper than the connecting piece. The device light have to be positioned higher. Only use
as little hose as necessary. The hose connecting piece must be removed for operation with the collecting vessel.
