The inbuilt humidistat is located in the cover of the device. It reads the humidiy of the incoming air, and depending on the set value,
switches on the compressor. In indoor swimming pool halls, the optimal air humidity level should range between 55% and 65 %.
Decreasing the level of humidity under the above mentioned range is not desirable, considerating the physiological aspects as well
as the aspects of providing building protection. Moreover, it increases the consumption of electrical energy. The humidistat can be
controlled by the user.

In case the control circuit reacts too
slowly, reduce the hysteresis. In case the
control circuit is unstable (switches on and
off alternately), increase the hysteresis.
The correction function is used in case of
difference between the currently shown
value and the real exact value (detected
by etalon, e.g.)

Condensed water is drained from the device by the force of gravity. It is necessary to locate the device in a way that enables
sufficient condensed water gradient. The condensate must be delivered through a siphon into the sewer or into the outside
environmemt. It is strictly forbidden to deliver the condensate back into the swimming pool, as it may be bacterially contaminated.
There is a tube for condensed water delivery located at the bottom of the device, on the left side. This tube must be plugged into
a sewerage pipe with an internal diameter min. 18 mm.

The cover can be disassembled by releasing of two screws located at the side parts of the device. Release the screws, pull the
bottom part of the cover toward yourself and then, by lifting it shortly, rake down the cover from the rear plate. The unit installation
is performed in an adverse way.
6.3. Dismounting and mounting of the cover
The unit must be installed in compliance with the local installation and electrical installation regulations !
6.1. Unit location
The unit is intalled on the floor. It is essential to ensure good air circulation by keeping the space free in front of equipment and
at least 200 mm above it. For the purpose of maintenance, it is further necessary to allow at least 200 mm of free space on both
sides of the unit.
6. INSTALLATION GUIDE
The equipment has a self-supporting construction and is very easy to install.
There is an elevated adjustable stand included in the equipment accessories.
6.2. Equipment fixation
The compressor´s operation starting is for securing its protection, delayed by min. 3 minutes. Depending on the humidity of
environment, it may last even longer. The user must not manipulate with the setting element of a time relay.
3.3. Compressor regulation
It is necessary to make sure that the intake and exhaust outlets are not covered. It is forbidden to place towels or other clothes
on the exhaust outlets to dry them. Cleaning of the device´s cover is allowed only by using non-abradant cleaning agents. In case
there is a water dripping from the equipment, please check whether a condensate pipe is not obstructed.
At least once a year, it is necessary to have the unit checked and cleaned by a service specialist. This is necessary in order to secure a
long operational life of the device. Cleaning the interior parts of the device by a user is not recommended, as this may lead to a
damage on the unit. The device contains mobile elements as well as elements under electrical pressure, therefore the interior parts
can be cleaned only by a certified electrician with an appropriate knowlegde of refrigerating technology.

EN - WALL-MOUNTED SWIMMING POOL DEHUMIDIFIER - USER´S MANUAL
The unit´s connection into the mains and its protection must meet the requirements of relevant norms. The connection
requirements are the following: 220-240 V/50Hz, 16A protection secured by a current protector with a nominal differential shut-off
current not exceeding 30mA. There is a terminal board for connecting the unit to the main, located on the left hand side of the
device. The master switch of the device must be located outside the swimming pool hall and it must be bipolaric and with L and N
conductors´ disconnecting. The dehumidifier must be inbuilt to a steady point for disconnecting the appliance from the mains with
a minimum 3 mm distance between the contacts for all the poles and in a switched off status.
The dehumidifier´s connection to the mains must be performed only by a qualified professional.
The dehumidifiers are simply adapted also to installation behind the wall into the adjacent room. In such case, only two grids are
visible in the swimming pool area. In the configuration for installation behind the wall, conduit adapters are screwed onto
the dehumidifier´s backside sheet. The adapters are delivered for passage through the wall of the length of 400 mm. In the place
of installation, they are shortened from the side of the swimming pool as necessary.
Flanges on the direct pieces are slipped on, so they can be cut into appropriate sizes directly in a place of assembly. Afterwards
the flanges are rivetted. The set also includes sealing band and screws for flanges´ connection.
