Section 3 – Operation
The aim of the Komfort Evap Cooler is energy efficient, quiet and safe air cooling of the residence. Its
indirect cooling function is to cool the fresh air-supply without affecting the humidity. When there is
sufficient suction of air, the yield will increase as the outside temperature rises,
Relatively high residence humidity will negatively impact the appliance operation, as it is cooled through
a evaporation principle.
3.1 Principle operation
The Komfort Evap Cooler can easily be placed on the return air of the MVHR. The warm air from the residence
area transports through o a humid matrix. This cools down the air to almost the wet bulb temperature of the air,
for instance 29C/30% cools down to 20C/75%. The adiabatic cooler has an efficiency of 80%.
The cooled air is stored in the MVHR, which makes the heat-exchanger a cool-exchanger. The warm outdoor air
flows through the cool-exchanger and is cooled before blown into the residence area.
BEWARE: the effect on the room temperature is limited to the limited airquantity.
Application
The Komfort Evap Cooler can be applied to all MVHR systems, where during the warmth exchange, no humidity
transfer took place between the airsupply and airreturn. Application on the enthalpy exchanger is possible, this
will increase the humidity in the air supply.
3.2 Safety
The SHC80 duct sensor supplied also measures the relative humidity and temperature in the duct after the cooler.
This position guarantees the best efficiency and safe operation, no condensate in ducts under the normal
conditions of use of our design.

Section 4 – Use
4.1 Description of the components
The main components of the cooler are:
The housing
The housing of the cooler is made of EPP (expanded polypropylene). The advantages of this material are its low
weight, good water tightness, good air tightness and recyclability. The housing consists of an upper and a lower
part that are fixed to one another by two Mounting rings. At the bottom is the compartment there is a water valve,
controller board and transformer located. These are protected by an EPP cover bearing safety symbols. On left
and right side the duct connection is located, diameter 200mm internal and 250mm outside
Internal construction
The internal construction has been developed to provide an optimum air flow that is safely humidified. It consists
of a cassette in which the matrix is fixed. The supply water humidifies the matrix. The air supplied passes through
the matrix and is humidified by contact with the wet surface. Surplus water is drained.
Humidity and temperature sensor (SHC80)
The SHC80 duct sensor also supplied measures the relative humidity and temperature in the duct after the
cooler. This position guarantees the maximum operation and condensate-free ducts under the normal
conditions of use of our design.
The control
The cooler is controlled by a (wireless) control panel.
This control panel fitted with batteries (4xAAA) is linked uniquely to the cooler. See separate Controller manual.
Operation
As soon as the temperature sensor in the control panel measures a higher temperature than the setpoint it
activates the cooler. The software has been developed to achieve an optimum output and minimum water
consumption, at the lowest energy costs.
Safety
The control is fitted with a Legionella flushing program, in addition the control has a number of other built-in
safety devices and indication functions.
The necessary reports are also transferred to the display.

Section 6 – Installation
6.1 Order of operation
1. Choose the location of the cooler in the air return duct as close as possible to the MVHR unit. The
minimum distance after a bend is 150mm.
2. It is important that during installation sufficient space is available so that the unit can be rotated at time of
doing service = replacing matrix cassette. At least 200mm from the ceiling.
N.B.! Unit must be mounted level in all directions
3. Keep at least 100 millimetres clear space at the bottom.
4. Install the cooler horizontally between the ducts or air hoses.
The unit must hang level to guarantee good water drainage.
5. Use brackets with M8 thread connection to mount the unit.
6. Connect the black 4mm hose with the ¾” adapter to the mains water supply, for this use a ¾” washing
machine tap with check valve
7. Make sure that the water pressure is between 1.5 bar and max. 3.5 bar.
8. The cooler is supplied with a 16 millimetre drain hose with a length of 50 centimetres.
N.B.! The drain hose must be connected to the sewer depressurized and
with sufficient fall! NO water may remain in the hose!
9. The water consumption is a maximum of 1l/min in case of a pipe fracture or faulty water supply valve,
normal use max 2l/hour. The minimum diameter of the drain must be 25 millimetres.
10. Fit the humidity and temperature sensor (SHC80) as close as possible after the unit in the air duct to the
dwelling, maximum distance 100 centimetres.
N.B.! The sensor(s) may not be damaged or get wet!
11. Open the water supply tap and check for leaks in the water supply and the drain.
12. Insert the plug into the socket. Check the voltage, green power LED comes on and the service LED will
go on for 5 sec and off for 5 sec. This means that the test cycles is started. The valve will open for 90 sec
and the heater will go on for 30 sec.
13. Check the drain again for correct operation after 1 hour.
14. The cooler is now ready for operation.
15. Open the packaging of the control panel.

Section 8 – Maintenance
The cooler is equipped with a removable cassette in
which a matrix is fitted. The matrix cannot be cleaned.
The cooler cassette must be replaced at least every
year to guarantee safe and healthy humidification. A
service message is triggered that is visible by a LED
coming on (next to the lock symbol) at the bottom of
the cooler.
8.1 Procedure for replacing cassette
1. Remove the plug from the socket.
2. Disconnect the water supply.
3. Make sure that the drain hose is free and can move with the movement that is necessary to gain access
to the top.
4. Make sure that the water supply hose has sufficient room to move with it, or disconnect from the tap.
5. Undo the screws on the side of the brackets so that the cooler can be turned in the bracket. Use a
crosshead 2 or 3 screwdriver.
6. Turn the cooler 90° so that the cassette is accessible. Take into account any leakage water from the
side of the unit!
7. Disconnect the cassette from the water supply by pushing in the ring of the knee joint (on side of the
housing) and sliding the whole knee off of the black hose. In this way the cassette is disconnected and
can be removed.
8. Pull/slide the cassette out of the cooler.
For this use the tool supplied with it or water pump pliers!
9. Clean the inside of cooler with a soft cloth if necessary.
Do NOT use a cleaning product!
10. Remove the new cassette from the packaging.
11. Push/slide this into the unit.
12. Push the black hose of the new cassette into the knee joint.
13. Turn the cooler again such that it hangs level.
14. Tighten the brackets.
15. Open the water supply duct
16. Insert the plug into the socket.
17. Your cooler is again safe, reliable and ready for a new period!
NB: The whole used cassette can be disposed of with the residual waste.
