INSTRUCTIONS FOR USE
3.1.
Humidity regulation with an inbuilt digital humidistat located in the cover of the equipment
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.
Luminous point
signals, that the
humidity is shown on
display.
Luminous point indicates
that the regulator gives
signal to heat the air. This is
applicable if LPHW and
Solenoid valve are installed.
Not illuminated point
indicates that the requested
air temperature is lower than
actual.

By keeping the “set” button pressed for longer than 5 secs, the setting gets finished and you return to a mode of current
humidity display.
In case of inactiveness for longer than 30 secs, this is done automatically.
3.2.
Humidity regulation with a back-up mechanical humidistat located in the electronic box
In the electronic box there is a back-up mechanical humidistat, which is set on the value of 70 % RH. This humidistat has a back-up
function in case of digital humidistat failure. User should not perform any regulation of this humidistat.

3.3.
Compressor regulation
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.
4.
MAINTENANCE INSTRUCTIONS
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.
5.
SERVICING THE UNIT
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.
6.
INSTALLATION GUIDE
The unit must be installed in compliance with the local installation and electrical installation regulations !
6.1.
Unit location
The unit is to be installed on the floor or on the wall. To ensure the right operations of the dehumidifier and its maximum efficiency in
terms of humidity control, it is necessary ensure proper air circulation into and from the dehumidifier. This requires the actual unit
placement appropriately into the swimming pool hall respecting basic prerequisites of air circulation and air flow. It is strictly
forbidden to install the unit just below the ceiling. At least 200mm of a free space must be kept above the unit. Each swimming pool
hall is individual thus a special care needs to be taken to choose a proper dehumidifier placement. It is also strictly forbidden to block
the air inlet and outlet with any objects (canoe, buckets, ceiling beams, etc.). For maintenance purposes please keep free space of
200mm on both sides of the dehumidifier.
6.2.
Equipment fixation
The equipment has a self-supporting construction and is very easy to install.
There is an elevated adjustable stand included in the equipment accessories.
6.3.
Dismounting and mounting of the cover
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.
6.4.
Condensate drain
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.

Connecting the device to the mains
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.
6.6
Mounting behind the wall - to order
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.

6.7.
LPHW heater element - to order
The LPHW heater elements are supplied only to order. Connection of the hot water heater element onto the LPHW plumbing is
carried out similarly to the installation of radiators. On the feeder pipe, it is connected by a control valve and on the return pipe by a
closing screw joint. The LPHW is not supplied with a control valve and a screw joint; these are supplied by the supplier of the
heating.

Attachment of the heater element to the distribution of the heating water
After installing the LPHW plumbing and leading the LPHW into the element under pressure, it is necessary to bleed the heater
element. The bleeding valve is located on the feeder pipe of the LPHW heater element. To secure that the LPHW heater element
works always at full heat output, blowing onto the unit by a fan must be provided even when no dehumidification is being
performed. Therefore, when using the LPHW heater element, the switch of fan operation must be switched into the position of
continuous operation.
