WALL-MOUNTED SWIMMING POOL DEHUMIDIFIER - OWNER´S & INSTALLATION MANUAL

The inbuilt humidistat is located in the cover of the device. It reads the humidiy of the incoming air,anddependingonthesetvalue,
switches on the compressor. In indoor swimming pool halls, the optimal air humidity level should range between 55% and 65 %.
Decreasing the levelofhumidity under the above mentioned range is notdesirable, 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 theuser.

Under the inside coverofthe unit, thereis a two-positional fan modeswitch. In the firstposition, the fan runs evenif the compressor
of the appliance has stopped continuous operation of the fan. In the second position, the fan only runs simultaneously with the
compressor periodical duty ofthe fan. The continuousoperation mode ofthe fan is preferable, since the humidity readerbuilt in the
device continuously reads humidity, and thereforea greater accuracy isreached. Atthe sametime, continuous operation ofthe fan
results in better air circulation in the room. The installation worksupplier selects the mode of the fan according to the request of the
user.

3.2. Humidity regulation with a back-up mechanical humidistat located in the electronic box

In the electronicbox there is a back-up mechanical humidistat, which is set on the value of 70 % RH. This humidistat has a back-up
function in caseof digital humidistat failure.User should not perform any regulation of this humidistat.

The compressor´s operation starting is for securing its protection, delayed by min. 3 minutes. Depending on the humidity of
environment, it maylast even longer.The user mustnot manipulate with the settingelement of a timerelay.

3.4. Compressor regulation

It is necessary to make sure that the intake- and exhaust outlet are not covered. It is forbidden to place towels or clothes on the
exhaust outlet, to dry them. Cleaning the device´s cover can be done only using grooming articles suitable for rustless steel
surfaces. In casethere is a waterdripping from the equipment,check whether a condensate pipeis not obstructed.

At least oncea year, itis necessary to have the unitchecked and cleaned by aservice specialist. This is necessary in orderto 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. Thedevice containsmobile elementsas wellas elementsunder electricalpressure, thereforethe interiorparts
can be cleanedonly by a certified electricianwith an appropriate knowlegdeof refrigerating technology.

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 wall or on the mobile stand. 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 swimmingpool 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 and at least
150mm below theunit. Each swimming pool hall is individual thus aspecial care needs to be taken to choose a proper dehumidifier
placement. It isforbidden to install theunit on the ground. Itis also strictly forbiddento block the airinlet and outlet with anyobjects
(canoe, buckets, ceiling beams, etc.). For maintenance purposes please keep free space of 200mm on both sides
of the dehumidifier.

The equipment hasa self-supporting construction and is very easy toinstall.

There is an installationbracket included in theequipment accessories, which must be fixedon the wall. The axisof the fixation slots
is 210 mmlower than the top edge of the device. The distance between the fixation slots is 420 mm (DRY 300 SILVER/METAL) and
360 mm (DRY500 SILVER/METAL). When thebracket is fixed,it is possible tohang up the device withoutdismounting its cover.
