Declaration of conformity 19
To maintain a healthy indoor environment closely-controlled
ventilation is essential. There are many pollutants that will
affect the indoor air quality: human body waste products
in shape of CO2, dead skin, perspiration and moisture.
Add to this the waste product of cooking (cooking-smells),
showering (moisture), gases from building-materials and
the waste products of pets.
Without proper ventilation this environment would be perfect
for the growth of mould and subsequently damage to the
decoration and fabric of a dwelling.
The HRC unit is fitted with two fans: The exhaust fan ensures
that warm damp and polluted air as near as possible to
the source will be extracted. The exhausted air must be
replaced with fresh air and so the HRC heat recovery unit
has not only an exhaust fan but is also fitted with a supply
fan and air filters.
The supply air, which in winter is colder than the inside air, is
heated in the heat recovery unit using the heat of the exhaust
air by means of the heat-exchanger. This heat exchanger
has an efficiency of 97%, so a minimum loss of heat takes
place and the supply air temperature is at an acceptable
and comfortable level.
In the summer, when heat-recovery is not desirable, the air
does not go through the heat exchanger, but is diverted by
way of a bypass-valve. By doing this during the night, with
relatively cool supply air to ventilate the dwelling, a cooler
dwelling temperature is possible. This is automatically
detected and controlled by the unit electronics.
The electronics also ensures, that in winter, when ice-formation
in the exchanger is possible, the exchanger is defrosted, at a
time that is most comfortable to occupants of the dwelling.
Further the fan speed will automatically switch up to a
higher setting when a 5% increase in relative humidity is
detected within a 2 minute period (usually during showering
or cooking). After a preset period the unit will return to the
lower set speed. The fans are energy-low by the use of EC-
motors with a constant (adjustable) air volume.
The filters in the unit ensure that the fresh supply air is clean
as it enters the dwelling. Also the extract air from the property
is filtered, so that the pollution of the heat exchanger is
minimised.
These filters have to be cleaned every month, depending
on the pollution. The electronics in the unit is fitted with a
timer for filter cleaning which automatically indicates when
it is time to clean the filters. The maximum period between
replacements of the filters will be a year.

2.1 General
The Orcon HRC is a complete heat recovery unit, which is
fitted with an intelligent electronic control system to ensure
optimum efficiency and protection under all conditions.
The unit can easily be set up for left- or a right-handed opera-
tion. By changing the position of a module at the top of the
unit it can quickly be configured to accomodate the ducting
to outside on either the left or on the right side of the unit.
With the screws and plugs supplied fit the unit horizontally
to the wall. A standard the unit is delivered complete with a wall
mounting frame, fitting instructions, fixing kit and a condensate
discharge trap. A wireless remote control is an optional extra.
2.2 Fitting HRC in brief
A Mounting frame: Mounted by means of the screws and plugs
supplied horizontally to the wall. Use the fixing points on
the drawing attached to the mounting frame. When the frame
is mounted horizontally to the wall, the ducting runs can be
completed. Remember that both ducts to and from outside,
will be fitted to one side of the unit and the ducts to and from
the house are attached to the other side of the unit. Also
the condensate discharge under the unit can be fitted at
this stage.
B When the ducting runs are completed if an appropriate
electrical supply is present, the installation can be com-
pleted. Now the heat recovery module can be attached to
the frame. Ensure that the “tree” on the left/right module
corresponds to the side of the unit with the ducts to and
from outside and the “house” is on the internal side. On
the central PCB (3.1) adjust the air volume of the fans for
low, middle and high speed. Both fans are adjusted to the
same airflow to guarantee a balanced airflow. Push the heat
recovery module fully to the back of the mounting frame
and turn the handles at the bottom 180° to lock the unit
in place. Also the condensation trap under the unit can be
securely fastened with the wire clip supplied.
C The cover of the unit can now be replaced and secured with
the two screws and the power-supply can be connected. The
unit will start-up immediately and begin to run but must be
calibrated as described on page 13 in the start-up-procedure.
When there are no failures during the start-up, the unit is
ready and fully commissioned.
For further information about the operation, adjustment, failures
and maintenance of the unit, read the next pages carefully.

3.1 Mounting frame
The mounting frame of the HRC can be fitted directly to the wall
with the delivered screws and plugs. The distance between both
mounting-holes will be 53 cm. Under the mounting frame
ensure there is at least 50 cm for the condensate discharge
to be connected. On the mounting frame is a drawing, which
indicates where to fit the condensate discharge. The position
of the electrical power supply (an earthed wall socket or fused
switched spur) is also indicated. The unit must be secured
horizontally. Ensure sufficient angle for the condensate
discharge. The installation must be in a frost-free room.
Make sure there is a free space of at least 80 cm at the front of the
appliance for cleaning the filter and carrying out maintenance
on the appliance.
3.2 Important instruction
The HRC unit must be installed in accordance with all relevant
Building Regulations and Health & Safety requirements and the
fitting instructions of the HRC 300/400 4B(P/RH)
Connect mains after mounting the ducts!
3.3 Connecting ducts
When the mounting frame is fitted, the ducts can be fitted.
On one side of the unit the duct to and from the dwelling, on
the other side the ducts from and to outside.
To prevent condensation on the outside of the exterior air,
the inlet duct and the air outlet duct from the HRC must be
insulated.
It is recommended that the ducts from and to the dwelling
and to the appliance use flexible ducting with a minimum
length of 150 cm and flexible connections of the ducts to and
from the outside to the appliance use flexible ducting with
a minimum length of 50 cm. Flexible ducting should be fully
extended but should not place any strain on the terminal or
fixings.
Remember when sizing the ducts that this part of the installation
will affect energy efficiency. So remember that energy will be
wasted, during the passage of the air through the ductwork,
if the ducts are too small. If possible ensure that the total
resistance of the inlet- as well as the exhaustsystem does not
exceed 100 Pascal.

3.4 Connecting condensate discharge
The condensation-trap must be mounted at the bottom of the
HRC with the wire clip supplied.
Caution! Before mounting you have to fill the trap with water.
The diameter of pipework to the air-trap is 32 or 40 mm. The
position of the drain is indicated at the drawing in the mounting
frame. The condensate water must leave through the drain
pipe. Take care that the distance between siphon and air-trap
will be enough for de-mounting and cleaning.

3.5 Placing the heat recovery module
After fitting all the ducts at the mounting frame, and after fitting
the condensate discharge, the “heart” of the unit can now be
installed. Take the heat recovery module from the carton and
push it from the front into the mounting frame.
Push the unit fully to the back and secure by turning the handles
at the bottom 180°.
Figure 6: Placing the heat recovery module of the HRC
After positioning the heat recovery module, the dip switches
can be adjusted to give the desired air volume. (See § 3.9)
Ensure that the filters are correctly located.
3.6 Replacing the cover
After the heat recovery module is fixed in place the cover
can be attached. Offer up the cover with its front pointing
downwards. Hook the two brackets on the lower part of the
cover into the slots in the mounting frame. Now you can fix
the upper side of the cover at the upper side of the mounting
frame with the two screws provided. If it is difficult to push
the cover totally against the unit open the flap in the cover.
After closing the cover (and flap) the unit can be connected
to the power supply.

3.8 Overview connection HRC
The HRC can be configured either as a standard or a mirrored
unit. As a standard unit, the duct connections on the left side
of the unit will go outside and the duct connections at the right
side go to the dwelling. The turn-module will show a “tree” on
the left and a “house” on the right side.
Figure 8: Turn-module
If the unit is to be configured as a mirrored unit, you can pull
the turn-module out of the unit and turn it 180° (reverse side
to the front) and insert it b ack into position. You will see that
now the “tree” is on the right side and the “house” on the left
side. The connections at the unit have now changed. The
connections on the left side now lead to the dwelling and the
connections on the right side lead outside.
Figure 9: Turn-module (detail)
The top connection is always the suction side (suction from
outside or from the dwelling) and the bottom connections are the
pressing connections (exhaust to outside or inlet to the dwelling).
The magnets on the turn-module are used to configure the unit
for left or right-handed operation and must not be changed or
removed after the initial set up.
Attention! Keep the magnet away from creditcards and other
objects sensitive to magnetic fields.
3.9 Adjusting the air performance
The HRC is provided with constant volume fans.
The integrated electronics controls the speed of each ventilator,
to keep the airflow equal conform the settings of the dipswitches
independent of the resistance of the system. For this reason
the speed of both fans will not always be equal, because the
resistance of the inlet and exhaust system will not always
will be equal.
By means of the dip switches on motor-pcb’s at both sides of
the unit, you can easily change the airflow of the highest speed.
To change the airflow of the ventilator follow instructions
below:
1. Remove the cover from the unit.
2. The dip switches on the motor-pcb’s on both sides of the unit
are now accessible
3. Set the dip switches on both pcb’s to the desired airflow after
checking the setting on the drawing below.
4. Refit the cover and make sure that the filters in the unit are
clean.
5. Restart the unit.
Important: Before removing the cover you must disconnect the
electrical power to the unit.

5.6 Setting transmitter / receiver (RH model only)
When current is put on the device, the red LED is flashing 3x on
the receiver print.
Login for 1 remote.
Press the pushbutton on receiver print for 2 seconds. The red LED
is flashing 2x, followed by continuously burning red LED.
On the remote, press [auto] and [key 1] simultaneously. Keep
pressing until the green LED on the remote stays.
When the remote is logged in, the red LED on the receiver print is
flashing 10x, then the green LED on the remote flashes 3x. Now
the remote is ready for use.
Login of 2 remote controls.
Press the pushbutton on receiver print for 2 seconds. The red LED
is flashing 2x and goes.
On the remote, press [auto] and [key 1] simultaneously. Keep
pressing until the green LED on the remote goes.
When the remote is notified, the red LED on the receiver print is
flashing 10x, thereupon the green LED on the remote is flashing
3x. Now the remote is ready for use.
Remote 2 is logged in the same manner as remote 1.
When a third remote is notified, it will overwrite the second remo-
te. The first remote stays logged on.
To replace remote no. 1, it is necessary to erase the print of the
home ventilator. Only then it is possible to notify a new remote(s).
Logout of the remote controls.
Press the pushbutton on receiver print continuously until the red
LED goes. After releasing the button, the red LED on the receiver
print will flash 5x. The link with the remote is now erased
Battery replacement.
When the LED indication on the remote does not react when one
of the buttons on the remote is pushed, it is probably due to a
low battery. To replace the battery, you do not need to contact
your installer.
You can easily do it yourself. The battery is commercially availa-
ble (typ: 3V CR 2032).
To replace the battery, you first slide the remote in a vertical
upward direction in order to detach the remote from the holder.
At the back of the remote, you find two screws, unscrew them.
Now you can remove the back of the remote. Remove the old bat-
tery from the remote and replace it by a new one. Make sure the
positive side/plus of the battery faces you. Replace the back of
the remote and screw. Replace the remote in to the holder.
If there are still problems arising, please contact your installer.
Please do not mount the remote control under a metal cooker hood.
Mount on a flat surface with the screws and wall plugs supplied.
