Fig.3
The unit works by drawing moist air over a refrigerated coil with a small fan. The cold coil of
the refrigeration device condenses the water, which is removed, then the air is reheated by the
hot coil. This process works most effectively with higher ambient temperatures with a high
dew point temperature(Fig.3).

4.1 Installation Precautions
4.1.1 To ensure that the installation is performed correctly and that the appliance will perform
perfectly, please carefully follow the instructions indicated in this manual. Fail to respect the
rules indicated not only can cause malfunctions of the appliance but also invalidate the
warranty, hence our company shall not respond for any damage to persons, animals or
property.
4.1.2 It is important that the electrical installation is made according to the laws in force,
respects the data indicated in the technical sheet and the unit is correctly earthed.
4.1.3 The appliance must be installed in a position that allows the routine maintenance, such
as filter cleaning.
4.2 Positioning
4.2.1 Avoid installing the unit in proximity to:
-positions subject to exposure to direct sunlight;
-sources of heat;
-in places with oil fumes
-places subject to high frequencies.
4.2.2 Make sure that:
-the wall on which the unit is to be installed is strong enough to support the weight;
-the part of the installation wall does not have pipes or electric wires passing through;
-the installation wall is perfectly flat;
-there is an area free of obstacles which could interfere with the inlet and outlet air flow;
-it is preferably that there is an outside perimeter-wall to allow the discharge of condensation
outside;
4.3 Minimum Installation Distances
4.3.1 Removing the four rubber feet of the unit are suggested if hanging it on the wall.

3. Specifications
3.5.1 Ultra-low noise
With the advanced air ducting technology and the super quiet cross-flow fan, the unit can
operate with ultra-low noise.
3.5.2 Ultra-thin casing
With the ultra-thin casing of 200mm, which is the result of compact design, the unit can
save more space for you when it is compared with the common dehumidifierswith the
thickness of 400mm.
3.5.3 Fashionable appearance
With noble &fashion arc frame and elegant & graceful snow white color, the unit will be
perfectly combined with your pool house.
3.5.4 Newly design controller.
With simple operating display, the newly developed controller makes the unit operation
easier and more user-friendly.
3.6.1 The dehumidifier is controlled by a built-in hygrostat set on one side of the unit and
the target RH value can be set ranges from 30% to 90%.
3.6.2 The unit will not start to dehumidify until the actual RH is beyond the setting value.
3.6.3 We recommend that an external hygrostat should be installed to ensure a constant
measure of the humidity in the pool area.
3.6.4 The location of hygrostat is as the following (Fig.4):

2. If there is no other failures of P3~E0, and P1 & P2 still exist, please disconnect the power to
the unit and connect again after 1 hour.
3. If only P3 exists, please keep the fan running for 30min. If P3 still exist after the running,
please disconnect the power to the unit and connect again after 1 hour.

6. Maintenance
To guarantee the unit reliable and security operation for a long time, it is suggested to maintain and clean
up the unit every six months.
. Please take the following steps to clean up the strainer regularly:
6.1 Maintenance
1）Press the two red buttons and drag it down slowly（Fig.8）;
2）Seperate the return air filter screen from the units as the image shown below（Fig.9）;
3）Take away the return air filter screen and flush it with water（Fig.10）.
4）
.
Set the filter net and the air return grille to the original place and press the limiting pin.
(Fig.11)。
5）Clean up the unit outer with soft and damp rag（Fig.12） To protect the paint-coat of the
unit, please don’t use rough sponge or corrosive detergent to do these.
Warning：Cut off power supply before cleaning or maintaining the unit.
