Function
Dehumidier A 155
The A 155 is a condensation dehumidier, and is
based on the principle that air moisture condenses on
cold surfaces.
The cold surfaces are created on the evaporator
(AEV) when the compressor (M2) transfers heat from
the evaporator to the condenser (KD).
The dehumidier is equipped with a fan (M1) that
transports the air through the dehumidier.
The air rst passes through the evaporator (AEV),
where the moisture condenses and is deposited on the
evaporator.
The condensate collects in a trough located
underneath the evaporator, is transported away.
The air then passes through the fan (M1) and the
condenser (KD). In the condenser, the air is warmed
up and the condenser is simultaneously cooled.
After this, the air can be heated by the auxiliary
heating system (E) before being released from the
dehumidier.
Pipe system
The pipe system has two functions: it distributes the
air and is used for hanging washing on. The diameter
of the drying pipes is(Ø60 mm) (3) prevents clothes
from creasing whilst drying.
Dry air from the dehumidier is blown into the pipe
system and distributed to the drying pipes (3) via the
base pipe (4).
Dry air is blown downwards through holes in the
drying pipes, and is distributed between the items of
laundry.
This dries the laundry evenly, even in the places that
are least exposed.
All tubes are made of extruded, anodised aluminium,
making them highly durable and corrosion-resistant.

Function
Instructions on connecting the control unit/timer can
be found under “Installation”.
When the timer (S1) is activated, the following occurs:
1. The contactor (K1) is activated and starts the fan
(M1) and the auxiliary heating (E).
2. K2 is activated via GT5 and starts the compressor
(M2).
3. When the temperature has risen to the set value,
GT1 cuts off the power to the auxiliary heating (E).
4. The temperature is regulated by the thermostat
(GT1), which, if necessary, connects the heating coil
(E) according to the set value.
5. When the temperature of the evaporator sinks,
there is a risk of ice crystals forming. If ice forms, LP
breaks the current to K2 and the compressor stops.
6. When the timer cuts out, the dehumidier stops
running.
Compressor (M2)
e compressor has two separate external motor
guards (GT6 and GT7). e motor guard function
(TK) is also built into the motor windings, stopping
the motor if it overheats. e function resets
automatically when the temperature returns to
normal.
Termal overload relay (QF1)
Protects the compressor from overload (Set value:
2.5A). It breaks the current to the whole machine if it
is activated.
Low pressure control(LP)
Breaks the current to the compressor if the
temperature is too low or if the refrigerant runs out.
Fan (M1)
The fan motor has no separate motor guard.
Instead, it is equipped with a thermocontact switch
(GT4). The thermocontact switch is located inside
the motor winding, and breaks the current if the
motor overheats. The thermocontact switch resets
automatically when the temperature returns to normal.
A capacitor is used to ensure correct fan function.
Thermostat (GT1)
GT1 controls the auxiliary heating (E) and can be set
from 0-9 (equivalent to approx. 0-40°C).
Overheating protector A 155F (GT2:1
and GT2:2)
GT2:1 and GT2:2 are two thermocontacts inside
the heating coil (E). GT2:1 and GT2:2 break the
current at 90°C. They must be reset manually when
the temperature has dropped. See the section on
maintenance.
Overheating protector A 155F (GT3)
GT3 is an overheating protector inside the heating
coil. It breaks the current to C3 at 70°C. GT3 resets
automatically when the temperature has dropped.

General advice on drying
Dehumidiers without a pipe system can have a pipe
system added later. A pipe system offers the following
drying advantages:
• The wide diameter of the tubes prevents creases
from forming on the laundry while drying.
• The dry air is blown underneath the drying pipes.
The air is distributed evenly through the laundry,
including the parts that are hard to reach, drying
the laundry from the inside out.
• Faster, cheaper drying.
• The drying pipes are stable and xed into place.
No drying room lines that hang down or risk
breaking
DRYING
- 15 -
OBSERVERA!
• Spin washing for at least 5 minutes before
hanging it to dry. The higher the spinning
speed, the shorter the drying time. Avoid
slow spinning if you have limited time for
using the drying room dehumidier.
• Distribute the washing evenly when hanging it
in the drying room.
• Keep doors and windows closed to prevent
damp air from entering the room.
5 min
