this User’s manual may lead to an injury or property damage and will lead to loss of warranty. To
prevent injury or property damage the following instructions must be followed:
3.1 ELECTRICAL SAFETY
The device operates at dangerous electrical current.
Only authorized person with particular electro-technical qualification can manipulate with unit.
Danger of electrical shock.
For proper and optimal operations of the device is it necessary to maintain the air
temperature in the swimming pool room / hall 2-3°C higher than actual water temperature
in the pool. It is also necessary to keep the air temperature in the swimming pool room / hall
in operational temperature range of the dehumidifier (specified in Technical data section).
Higher temperatures than operational temperature range may cause damage to the unit
resulting from overheating of the unit.

Do not climb up on or sit on the unit.
Do not place any objects on the top of the unit (e.g. boxes, flower vases, etc.).
Do not hang any objects on the unit.
Do not spray any flammable substances into the equipment; this might lead to fire.
Do not clean the equipment with aggressive cleaning agents, this might lead to damage or deformations.
When cleaning plastic parts do not use any cleaning agents unsuitable for the cover of the dehumidifier
(household cleaning agents, solvents, bleaching agents, benzene, diluents, rough cleaning powder, cresol,
chemical agents). Instead, sweep the dehumidifier cover with a soft cloth or a sponge.
Never throw or insert any objects into any hose or opening.
The cover of ceiling unit is made from acryl. The cover of compressor unit is made from powder coated
metal. Do not manipulate with lighted cigarette, cigarette ashes, or any other kind of fire in vicinity to this part.
Use this device exclusively for the intended purpose, as described in the attached instruction manual. Do not
use parts which are not recommended.
Do not drink or use the condensate water drained from the unit. Do not return the water back to the
swimming pool. The water may be contaminated with bacteria.
Children are not allowed to operate, touch or play with the unit.
Children are not allowed to manipulate with packaging, plastic / bubble foil. Risk of suffocation!
Prevent the children from injury or harm caused by any manipulation with the unit, its parts or its
packaging. Small parts like screws may be swallowed and cause suffocation or harm to health.
Do not leave the children in the swimming pool hall unattended.
The dehumidifier should be sized correctly and run max. 18 hours a day, optimum max. 12 hours a day. In
the case it runs more than 18 hours a day in long term it may fail, malfunction or get damaged. Warranty does
not cover such damages as the machine is considered undersized if running longer than 18 hours a day.

3.3 HANDLING PRECAUTIONS
Leave the compressor unit in vertical upright position for at least 2 hours before the installation. This will
level the oil inside the compressor.
Transport of the compressor unit in lying position or turning the compressor unit over may harm the
compressor and will lead to loss of warranty.
The device must be handled with care and special attention avoiding any mechanical damage.
It is forbidden to apply any improper mechanical force onto the unit. This may cause mechanical damage to
the device.
It is forbidden to let the device fall freely onto the ground or any solid surface resulting in hard impact.
Please notify your reseller or distributor if you suspect that the unit was delivered damaged. Unit may seem
to work well at start but small damage can make the unit go out-of-order in short time. In such case the unit
must be inspected and approved for further use by your reseller.
Please notify your reseller or distributor if directly after installation you suspect that unit is not working in
perfect order.
In the case of device failure resulting from improper handling or mechanical damage (impact, hit, fall, etc.),
the manufacturer reserves the right to evaluate the continuity of warranty.

6. INSTALLATION –CEILING UNIT
Ceiling unit is designed for an installation at the ceiling or at lower ceiling. Typically the ceiling unit is
fixed into the concreted structure of the upper floor or wooden roof. Please make sure that the
material into which the ceiling unit is to be fixed is suitable for such installation. Manufacturer is not
responsible for damages or losses caused by an incorrect installation or inappropriate concrete or
wood type. Ideally it should be installed above the evaporation source. It should be installed on easy
accessible spot to allow maintenance and service.

6.1 BASIC MANIPULATION
The unit is designed to be located on the ceiling. We, at Microwell, had to ensure a perfect balance
between weight and long-term durability with focus on reliability of the product. It is thus necessary
to mind below manipulation information and comply with them. Non-compliance may lead to
product damage, malfunction or failure. Manufacturer is not resosonsible for incorrect manipulation
or for manipulation not compliant to this User’s manual.
Ceiling unit is delivered in a box with polystyrene support from the bottom at sides.

SWIMMING POOL DEHUMIDIFIER DRY SIREN
Do not place ceiling unit on side. The unit is not designed to stand on its side. Main cover damage
may occur in such position.
Do not place ceiling unit on the ground. Do not put the unit on an object or support holding the unit
in the center.
Do not place any objects such as drill tools, boxes, vacuum cleaners, etc. on the top of the ceiling
unit.
Do not hold ceiling in areas where forbidden (bluetooth speaker, LED lamp, air outlet). For
manipulation hold the unit on the side which is supported by metal structure. Do not hold in places
where plastic cover does not have metal support.

DO NOT INSTALL THE CEILING UNIT IN BETWEEN THE WOODEN BEAMS OR SIMILAR
OBJECTS. Air flow on the outlet will be reflected from the object (wooden beam) and
redirected back to the unit. Thus the water collection process will be dramatically
reduced and the unit will be exposed to the risk of overheat.

concrete and 9mm bit by wood beam. Drill
2 holes (Lifting mechanism –Part number
13 and 16). Please refer to needed drilling
depth –section 6 INSTALLATION –CEILING
UNIT –table Concrete types and strength.
For wood we advise to drill completely
through. Please mind that wooden beam
must be statically resistant to hold weight
of DRY SIREN unit (53kg) and it must be
possible to drill 9mm hole through it
without changing the static conditions of
the wooden beam
4. By concrete insert 4 fasteners into the
holes for threaded bars. Fastener is part
number 5. Use small hammer or
appropriate.
