2 / ABOUT THIS DEHUMIDIFIER
2.1 INTENDED USE
Intended use of dehumidifier
The dehumidifier is designed for dehumidifying/conditioning atmospheric air only.
The air is filtered with a G4 filter.
The dehumidifier must be placed horizontally on the floor or on a table, and it should rest on the four rubber
supports.
The unit is intended for use in residential, commercial and industrial environments.
Operating conditions
NOTE
The operating conditions of the dehumidifier must be respected.
For process air supplied to the dehumidifier the following limit values must be respected:
Max. humidity ............................... 100% RH
Min./Max. temperature ............. -20°C/40°C
Max./min. pressure ..................... ambient +/- 300 Pa
Foreseeable misuse
Unless specifically stated in the user manual or in a separate agreement with Cotes or a Cotes Partner,
this dehumidifier must not be used for the following purposes:
Conditioning of gases other than atmospheric air at ambient pressure.
Conditioning air contaminated with any chemical or other aggressive/corrosive elements including salt
(sodium chloride).
Conditioning explosive or flammable air –including using the dehumidifier in ATEX-classified zones.

2.2 THE PRINCIPLE OF OPERATION
The effect of Cotes adsorption dehumidifiers basically stems from the action of two flows of air.
In this case the air is controlled by one fan, and the air is departed later in the drying process.
The drying process
The incoming moisture-laden flow of air enters one side of the cabinet and gets filtered by an air filter. The air
then passes through a slowly turning rotor whose inner surfaces are coated with desiccant silica crystals that
attract the water molecules passing through. When the moist air passes through the rotor, water molecules are
adsorbed and lodge in the pores on the surface of the silica gel. This means the air leaves the rotor containing
less moisture (humidity) than when it entered. And because the adsorption process releases energy to the air,
the temperature increases during the process. The air is then departed in to two separate airflows –Process air
and Regeneration air. Process air is the dry air.
The regeneration process
The regeneration air is then heated by heating element to reduce its relative humidity. On its way through the
rotor, this heat evaporates the moisture previously adsorbed by the silica crystals in the rotor. The resulting
water vapour now leaves the dehumidifier in the outgoing regeneration air.
The two air flows are fixed, and the rotor turns - this gives an automatic process of simultaneous water
adsorption and water extraction

3 / HANDLING AND STORAGE
Incoming goods inspection
Cotes recommends that customers:
•Inspect incoming goods for visible damage
•Photograph goods with obvious or suspected damage
•Verify that the incoming goods comply with either the delivery note or sales order
•If the delivery is found to be non-compliant, a written objection must be made immediately to the
delivery driver and the delivery company
•The delivery driver must countersign any objection letter
•Provide a copy of any objection letters to the delivery driver and keep the original.
If you do not inspect the delivery, but accept and sign the transporters receipt, then you will be liable to any
product damage or missing products.
If you do not sign the transporters receipt, but still are accepting the transporters unloading of his deliveries,
you are also liable to any product damage or missing products.
Handling
When ordering multiple dehumidifiers, they can be delivered on a pallet.
If the dehumidifiers have been delivered on a transport pallet, they can be moved using a forklift
Cotes dehumidifiers are built to be very durable so there is no need for any special handling other than normal
reasonable care and attention.
Do not stand on it or use it as a stool/staircase!
Storage conditions
NOTE
The storage conditions of the dehumidifier must be respected.
For storing the dehumidifier, the following conditions must be respected:
Relative humidity 0–90%
Temperature -25°C to 55°C
It is only possible to deviate from these ranges if such deviations were specifically mentioned when the order
was placed, and special considerations have been incorporated into the unit in order to deal with this.
Removing the packaging
The packaging must be disposed of in accordance with applicable regulations.
Please dispose of this packaging responsibly and recycle it if possible.

4 / INSTALLATION AND COMMISSIONING
4.1 HOW TO INSTALL THIS DEHUMIDIFIER
Safety precautions
NOTE
Electrical work should only be carried out by an authorised electrician,
and in accordance with national wiring regulations.
Electrical fuse size in the connected electrical installation:
Min. 10 A / Max. 16 A.
Any duct connections to and from the dehumidifier should only be carried out by authorised ventilation installer.
Also only use appropriate power cable and accessories made for this dehumidifier.
Where to mount this dehumidifier
NOTE
The dehumidifier must be placed indoors in stationary installations
and protected against rain and water on the cabinet.
The dehumidifier should be installed indoors, placed on a horizontal based surface.
It should be placed on the four rubber supports underneath the cabinet.
Also the dehumidifier must not be mechanically affected by other adjacent structures.
Minimum distance to other structures: 10 cm
Installation above sea level: Max. 3000 meter.
Where not to mount it
Unless it has been arranged with Cotes and special considerations have been made, the unit should not be
placed outdoors.
The unit should not be placed inside an office or in other locations where the sound pressure level must be kept
to a minimum.

Connections needed –electrical
NOTE
Make sure power is switched off before installing and servicing.
First, make sure that the selector switch is in position 0.
Now the power cable can be connected to the mains.
Connections needed –ductwork
NOTE
To ensure low pressure drop and low sound pressure levels,
please request assistance from a company that specializes in ventilation
systems.
NOTE
The regeneration air outlet duct should be directed at least a few degrees
downwards to allow for drainage of the condensed water.
If this is not possible, drill a ø6mm hole in the lowest part of the duct.
The main air to be dried is normally drawn from the room and through the main air filter. As standard, the
dehumidifier is delivered with a frame covering the filter.
If the installation is for normal room dehumidification at 50 - 100% RH, it is acceptable for the dehumidifier is
free blowing (no regulation). If lower dew points are desired, the dry air flow must be adjusted with a damper.
The regeneration air inlet should be equipped with a Ø80mm duct and a built-in filter. The regeneration air
outlet should be equipped with Ø80mm duct directed at least a few degrees downwards to allow for drainage
of the condensed water. If this is not possible, a Ø6mm hole should be drilled in the lowest part of the duct.
In order to adjust the regeneration air flow a damper must be installed on the regeneration air outlet.
If not, the regeneration air flow will –in most cases –be too high, making it impossible to reach the desired
temperature for the regeneration air and thus making the unit less efficient.
In general, ducts of the same size or larger as those placed on the dehumidifier should be used.
