INSTALLATION MANUAL
The dehumidifier
has been designed and produced
to give many years of faultless operation,
but like every mechanical system
a correct installation and
regular maintenance are vital.
We reserve the right to change our products
without prior notice.
We can never be held responsible
for any errors and/or omissions in this manual.

The units are separately packed in cardboard boxes, on one pallet tied with tape.
To prevent damage to the unit, it is recommended that the unit is transported to its final destination IN its packing.
When the unit is stored temporarily, it must be stored in a dry place until transport to its final destination
T

Smaller units can usually be moved by manpower and/or using a trolley.
To move larger units, a forklift should be used.
The units are always supplied on a pallet: please leave this in place until the final destination.
To prevent damage, note the following:
When using a forklift, ensure that the forks are long enough to reach to the end of the pallet.
When using a forklift the unit should only be lifted with the pallet or reinforcement under the unit.
Pushing with the forklift is permitted only if a rigid plank or reinforcement is applied over the complete length of
the unit.
The units should always be transported the right way up. Although under some circumstances they have to be
transported flat, e.g. to clear a narrow passage, they should never be placed flat for transport in trucks or for long
term storage (> 12 hours).
If the units must be moved in another way, other precautions must be taken to prevent damage to the housing.

Supporting material must be sufficiently strong
To prevent resonance, make best use of sound insulating material – see wall mounting kit.
Fitting or attaching the unit to wooden floors or walls is not recommended. This requires special precautions
(anti-rumble materials).
The units must always be levelled.
The units may only be installed one way up in a way that the compressor is always upright.
The suction of the unit should be at least 2,5 m from the water surface (protection volume – directions ARAI).

The condensation drain is connected via the bottom of the unit.
The condensation outlet is a 22 mm Ø flexible hose which must be connected to a PVC outlet pipe ∅32 mm, ideally
fitted with an odour trap (siphon).
To prevent water splashing into the unit and any undesirable odours, the connection must be made airtight to
prevent the intake of air via the outlet.
If the unit is placed below the drain level, the condensation pump may be used with a collector tank and float to
evacuate the water: flow 2 l/min and 3 m conveying height.

Used to keep the ambient area to temperature or bring this to temperature depending on capacity.
The hot-water battery (LPHW) is fitted on the pulse side of the unit.
The connection of the LPHW is on the right of the unit.
The LPHW must be connected to the CH boiler by a registered installer. The unit is not fitted with a circulating
pump. This must be fitted by the CH fitter and adapted to the capacity of the LPHW. The incorporated control can
be used to control the circulating pump and/or the CH boiler.
The unit can also optionally be equipped with a three-way valve 
HYDRAULIC CONNECTIONS
Fitted with ½” nipple connection to the LPHW.
The optional three-way valve is ½” external.
On the LPHW, the IN and OUT are marked LPHW IN and LPHW OUT
CONTROL
ELECTRICAL CONNECTIONS/ SEE DIAGRAM
The LPHW is controlled independently of the CH via the built-in 24V = control. When the dehumidifier functions, the
fan also moves air over the LPHW.
The thermostat (TH) or hygrothermostat (HYTH) orders the unit control to provide heat. The fan and circulation
pump are controlled by the PCB. A non-return valve should be fitted in the hydraulic circuit.
In order to prevent hot water flowing through when the swimming pool area is on temperature, one can apply a
built-in three-way valve.
ADVANTAGE: on heat demand, the three-way valve opens and water flows directly through the LPHW,
immediately providing heat.
