Thank you for purchasing the EcorPro DryFan® Dehumidier. The EcorPro DryFan® Dehumidier helps to monitor the humidity
and remove excess moisture from the air, keeping your living spaces, lofts, basements, boats, holiday homes, garages and
storage areas dry all day and every day.
This dehumidier can even be used for industrial processes and applications. It is designed to be
used almost anywhere, in any orientation and will even work upside down. It will perform similar to
compressor dehumidiers rated at double the capacity at normal room conditions.
Using DryFan® technology, this dehumidier will out-perform compressor dehumidiers by 3–4
times below 10 ºC. Where compressor dehumidiers stop working at 5 ºC, this unit will continue
to dry spaces and continue to work to -20 ºC making them ideal for unheated rooms and out-
buildings.
Please read this manual carefully before use to ensure proper usage and save these instructions for future reference.
The package includes:
• EcorPro DryFan® Dehumidier

PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE OPERATING.
When using electrical appliances, basic safety precautions should always be followed:
• The unit is designated for indoor operation.
• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or
lack of experience and knowledge, unless they have been given supervision or instruction concerning the use of the appliance
by a person responsible for their safety.
• Children should be supervised to ensure that they do not play with the appliance.
• Do not clean the dehumidier by spraying it or immersing it in water.
• Do not insert any object into the opening of the dehumidier.
• Disconnect from the mains before cleaning the unit or any of its components.
• Never connect to an electrical outlet using an extension cord. If an outlet is not available, one should be installed by a licensed
electrician.
• Place the dehumidier in location appropriate to the appliance IP rating (see technical data).
• Any service other than regular cleaning setting fan mode or lter replacement should be performed by an authorized service
representative. Failure to do so could result in a loss of warranty. Your dehumidier is supplied with an electrical cable (4200
mm) and an earthed plug. Should it be necessary to replace this plug at any time, you must use an earthed electrical plug.
• Never operate this appliance if it has a damaged cord or plug. If the supply cord is damaged an approved service representative
or a similar qualied person must replace it in order to avoid any hazards.
• There should be direct access to the electrical plug after connecting the power.
• Do not use your dehumidier under the following conditions:
• if the power cable is damaged
• close to heat source
• where small children may be left unattended
• where the power cable may be easily damaged
• where there is a risk of liquids falling on the unit
• where it may be damaged by chemicals
• This product is not made for DIY repair.
IMPORTANT SAFETY INSTRUCTIONS
This appliance must be earthed and should only
be connected to an earthed 220 – 240 V / 50 Hz
mains supply.
The installation must be in accordance with
the regulations of the country where the unit
is used.

HOW IT WORKS
damp air in
patented
regen heater
dry ltered
air out
wet air exhaust
patented dessicant rotor
Your dehumidier uses DryFan® technology and uses a
continuously rotating moisture absorbing patented wheel
termed a “rotor”.
A highly ecient yet low noise fan draws air into the unit
(Process Air) and forces it through a section of the rotor. As the
air passes through the rotor, the honeycomb, of hygroscopic
membranes absorbs almost all of the moisture creating an
extremely dry airstream.
Most of this airstream (approx 85%) is discharged directly
through the ‘Dry Air Outlet’.
However, a portion, (approx 15%) of this air (Regen Air) is
separated and directed through a special heater bank (Regen
Heater) where the air’s temperature is raised. This heated air is
then channelled back through a section of the rotor.
As this hot air passes through the membranes, its higher
temperature drives-out the previously absorbed moisture and
discharges it as warm wet air through the ‘Wet Air Out’ duct.
As the wheel rotates, this process of collecting and discharging
moisture is continuous.
The wet air outlet is 41 mm in diameter making it easy to
vent the moisture away using standard push t waste water
connectors.
Water is not drained away as a liquid it is vented away similar
to a tumble dryer.

PATENTED DESICCANT ROTOR
The Desiccant Rotor is the heart of the DryFan® system. It is an array of especially absorbent
membranes – patent protected – arranged as a series of corrugations (as shown in the cut-
away image) to give a vast surface area that was developed over many years, making it an
extremely ecient moisture collector.
PATENTED REGEN HEATER
A patented ceramic PTC Regen Heater. (PTC Positive Temperature Coecient) is self
regulating it never overheats. However, as triple safety we include a separate overheat smart
sensor in the dehumidier. The patented technology is both safe and energy ecient and can
never overheat to hazardous temperatures, even if vents become accidentally blocked.

CONTINUOUS FAN OR FAN ON WHEN DRYING ONLY
MODES
The DryFan® Dehumidier can be used in two modes:
Mode O – The fan is always blowing and circulating air
continuously dehumidifying at the set humidity point by the
humidistat. This has the benet of a faster reaction time to
uctuating humidity levels.
Mode I – The fan is working only when needing to dry the air. The
reaction time to humidity level change may be up to 1 hour in this
mode, but it is more energy ecient and of course quieter working
only when needed.
SELECTING FAN MODE
Modes for the fan can be changed by disconnecting the
dehumidier from the power supply by unplugging. Remove the
four screws holding the top cover in place with a screwdriver. On
the inside just under the lid is a switch. Pressing the switch will
mean mode change from one mode to the other.
Replace the cover the right way round (there is only one way for all
screws to align). Put screws back into position taking care not to
overtighten.

UNIT SETUP
POSITIONING THE DF8/DB8 DEHUMIDIFIER
The DF8/DB8 DryFan® Dehumidier have been designed for indoor use however, it can be placed inside or outside the room to be
dried.
Internal Positioning:
When positioning the unit inside the room, place it centrally, ensuring inlet and outlet ducts are clear of obstruction. If required,
ducts can be connected to the outlet and/or inlet (where tted) to direct the drying to specic areas. The ‘Wet Air Out’ MUST be
ducted outside the room.

POSITIONING THE DF12/DB12 DEHUMIDIFIER
External Positioning (Models where Outlet Duct Fitted Only):
When positioning the unit outside the room, connect ducting to the outlet to direct the dry airstream into the room to be dried.
Optionally, the inlet may also be ducted to the room to give a re-circulation eect. In this case however, because the unit uses
a portion for the inlet air for regeneration. Provision must be made in the inlet duct to draw air also from outside the room.

NOTE:
1. As the wet-air-out discharge is warm and very humid, ensure it is directed where it will have no adverse eect on the
immediate environment.
2. Wet-air-out should be declined from the dehumidier where possible if there is a risk of any condensation build up in the
exhaust duct running back into the dehumidier.
This can be avoided either with short wet-air-out duct lengths or adequately insulating the wet-air-duct to prevent
condensation. Should water be seen dripping from the dehumidier switch o the appliance immediately at the wall socket.
Allow water in the unit to dry completely.
Correct the defect in the wet-air-out ducting and reconnect to the power to start operating again.
Do not operate If there is a concern the unit is not thoroughly dry inside.
3. The wet-air-out ange outlet is 40 mm. This is the standard size of push t wasted water pipe connectors and pipes ideal for
exhaust ducting.
Decreasing the exhaust pipe diameter will decrease performance. Flexible ducting may be used on all inlets and outlets.
All ducting lengths should be kept to a minimum. Longer lengths will reduce performance.
For the longest lengths see FAN SYSTEM section (page 6). Ducting may be also supplied by your dehumidier supplier.
