Usage specification

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.

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/50 Hz, 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.

The dimensions of building slots are quoted.
6.6.1 Installation outside
When the dehumidifier is installed outside, it is equipped with special insulation to prevent condensation. The insulation thickness
is 4cm K-Flex ALCLAD ST 19 R.
Back side of the unit is equipped with special double insulation with aluminum layer on the top.
When installing the through the wall ducts, please apply insulation on revealed places to prevent condensation. Please note that
typical swimming pool has 30°C and 60% RH. Due point in these conditions is 21.4°C. Outside temperature is lower than this value
for most of the year. It is thus essential to insulate all places where condensation may occur. Manufacturer supplied 2 pieces of
extra insulation for this purpose.
When unit is placed outside the unit is equipped with Winter module and Condensate tray defrost. Winter module keeps the
compressor temperature at certain level to maintain oil viscosity. This helps overall performance of the unit and long term
reliability. Winter module activates when compressor is off (no dehumidification) and outside temperature is lower than 2°C.
Condensate tray defrost is a standard feature applied when unit is used in subzero temperatures. The unit is by standard equipped
with heated and insulated condensation hose. Please do not cut or shorten the heating element. It works automatically when there
is ice or condensate formed and outside temperature is lower than 2°C.
Should your unit be equipped with a wireless control DRY EASY 300, then the antenna is packed inside the machine. During the
installation please take it out through the air OUT ducting and keep it inside the ducting. This will improve the quality of signal
transmission.

6.8. Air filter - to order
Your dehumidifier may be equipped with an air filter on demand. Air filter is to gather dust and other mechanical particles and
prevent them entering aluminum heat exchangers. Although air filter contributes to cleanness of your dehumidifier, it has no HEPA
(antibacterial) filter functionality.
Your dehumidifier's operation is very much dependent on continuous free air supply. It is then important to keep your filter clean.
Please review simple steps below how to clean your filter. In the case filter is not cleaned it creates a barrier for air supply. This has
negative effect to your dehumidifier's operation and may result in its malfunction, damage or a complete failure. Some pools require
cleaning once a year, some once a month some once a week. Time period in which your filter needs to be cleaned is very much
dependent on actual individual conditions in your pool hall. It is then required to clean the filter at least once a month. Manufacturer,
distributor or resellers are not responsible for malfunctions, damages or failures resulting from not cleaned filter.
When exchanging the filter power supply to the dehumidifier must be cut and the unit turned off.
1. Remove the dehumidifier cover.
Please watch out for controller
connectors such as cables or
antennas!
2. Unscrew 2 screws on the right
side and slightly release 3 screws
on the left side.
3. Lift the filter and move it down-
left-ward.
4. Remove the filter from the
dehumidifier.
5. Clean the filter using vacuum machine or rinse with fresh warm water. If needed you may apply non aggressive cleaning agent. Please let the filter dry in
shade. Do not expose the filter to sun.
6. Please install the filter back by undertaking above steps in reversed 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.
6.7. LPHW heater element - to order
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.
