Foreword
Installation manual for the contractor
Dear contractor,
Thank you for purchasing the fresh-r®On-The-Wall or the fresh-r everywhere® On-The-Wall .
This manual is intended for professionals and contains all the necessary installation information.
To install the fresh-r®correctly and safely, it is essential that you read this information carefully
and familiarize yourself with the fresh-r®before you start. The fresh-r requires a fused 230 V
mains electricity supply and must be connected by a qualied electrician.
Other information relating to the target group can be found in chapter 2.
The information in this manual is important for the correct and safe installation of the fresh-r®.
With the table of contents you’ll be able to nd the right information in the manual quickly.
This is the installation manual. Besides this manual there is also an user manual available.
NOTICE
This manual covers two fresh-r systems:
1. fresh-r®On-The-Wall
2. fresh-r everywhere®On-The-Wall
Therefore some illustrations might dier from the actual model you have purchased.
Details about the fresh-r everywhere®On-The-Wall are to be found in appendix 15.2.

1. Intended use
The fresh-r®On-The-Wall is a decentral ventilation unit with heat recovery. The fresh-r®takes
heat from the stale air it expells and uses it to warm up the fresh air it brings in from outside.
It improves air quality for a healthy indoor air quality and at the same time reduces your energy
bill. No ducting is needed for this unit, which makes installation easier than a conventional HRV
system. The fresh-r®is equipped with CO², RH and temperature sensors and has an intelligent
control system and other than conventional HRV’s the fresh-r®also works ecient at sub zero
temperatures.
The fresh-r®On-The-Wall may only be installed on a wall.
2. Target group
The manual describes how to install the fresh-r®. The installation must be done by contractors
who are familiar with local building regulations.
Connecting the fresh-r®to the mains electricity supply must be done by a qualied electrician.

2 Prepare the wall
You will need two round holes (Ø 160 mm) in the outer wall of the building, for the air
pipes; the lowest hole needs to have a slope of 2 degrees. You also need four holes in
order to attach the fresh-r®on the wall with four screws 6 x 120.
For ecient ventilation place the unit centrally in the room, ideally at least at 80 cm from
the oor level, but not too high. You must be able to see the controls easily.
Mark the openings using the cardboard wall-cut/drilling template supplied. See g. 3 and g. 4.
Draw the holes
To draw the holes, do the following:
1. Place the template against the outer wall, make sure it’s vertically leveled.
2. Tape the template on the wall. Use removable tape in the corners.
Make sure “UP” is visible and is pointing upwards.
3. Mark the centres of the big holes by tracing the four notches around the hole.
Use a pencil and a ruler to make two crosses. The crosses mark the centres of the
holes.
4. Mark the centre of the four corner holes.
5. Remove the template.
Check the centre distance of the two big holes.
The centre distance should be 897 mm.

The big holes
To drill the lower big hole (160 mm), do the following:
1. Drill through the outer wall(s) at a downward angle of 2 degrees.
This is to allow the condensate to drain towards outside.
To drill the upper big hole (160 mm), do the following:
1. Drill straight through the wall(s).

g. 5 Make sure the wall is well prepared
2. Remove dust and other materials from the holes.
3. Get a duct pipe (this is the blue PVC pipe) with EPP cover (this is a foam tube) and
try if it ts the holes.
The four corner holes
To drill the four corner holes, do the following:
1. Check the dimensions as shown in g. 6.
2. Drill the four corner holes. Use a 8 mm masonry drill.
3. Place plugs into the four corner holes.
You’ll nd the plugs in bag A.

3 Cut the duct pipes
NOTICE
Make sure if you cut the duct pipes, the part you want to keep has a lip.
To cut the duct pipes, do the following:
1. Remove the EPP covers.
2. Cut the upper duct pipe (input fresh air) to the total width of the
wall (D1) + 15 mm.
Tip: Use a wide tape or two paper sheets taped together to mark the duct pipes and get a
perpendicular cut.
3. Cut the lower duct pipe (output stale air) to the total width of the
wall(s) (D1) + 55 mm.
4. Deburr the duct pipes. Use a deburring tool, such as a le.

4 Place the duct pipes in the Unibody
NOTICE
Use the provided EPP glue for the lower duct pipe. The lower duct pipe is the condensate
drain and needs to be water tight. Apply PVC glue to the last 3 cm of the duct and to
the white ring. Make an airtight connection: the air in the ducts can be very cold. No
warm, moist indoor air may reach the cold ducts.
1. Put PVC glue on the white ring which is located in the inside of the stale air output
socket (see g. 9). Do not put PVC glue on the freh air input tube.
g. 9 Put PVC glue in the stale air output socket on the white ring only
2. Place the duct pipes into the Unibody.
Make sure the lips are pointed towards the bottom side of the Unibody.
These are needed to mate with the outside wall grills.

5. Put EPP glue around the edges of EPP covers of the upper duct pipe and the lower
duct pipe.
NOTICE
The connection of the lower duct pipe and the upper duct pipe to the Unibody needs to be
airtight because air leaks can create unwanted condensation.
g. 13 Put EPP glue around the edges of the covers
6. Cut the Epp covers. They need to cover the whole duct pipe.
The lips need to extend beyond the covers.

1. Remove the four corner bolts (don’t remove the middle bolts).
g. 16 Remove the four corner bolts
2. Put expanding foam around the edge of both EPP covers. Make sure the expanding
foam insulate the whole edge of the EPP covers in order to prevent air leaking
(regarding the inner wall).
g. 17 Put expanding foam around the edge of both EPP covers.
3. Place the Unibody in vertical position and open the door as far as possible.
4. Press the two storm ap levers to ensure they are open.
DON’T remove the
two middle bolts

g. 18 Press the two storm ap levers
The following steps need to be done by two persons.
First read step 5, 6 and 7 so you are well prepared. Then perform the actions.
CAUTION
Be carefull with the door. Giving too much pressure can damage the door or it’s hinges.
g. 19 Be carefull with the door
DON’T apply force to
the the door, when
raising the fresh-r®.

5. The rst person:
Hold the Unibody as shown in g. 20. Place the Unibody with the upper duct pipe
and lower duct pipe in the wall. See g. 21.
CAUTION
Hold the Unibody till it’s mounted with the four 6 x 120 screws.

g. 20 Hold the Unibody as shown in this
gure
g. 21 Place the Unibody on the wall
6. The second person:
Mount the 6 x 120 screws in each corner of the Unibody (4 ×). Use a screw driver.
CAUTION
The ducts and the holes must have an air tight seal. To establish this, it’s critical that all
four screws are properly functioning. Make sure the fresh-r®is pushed rmly to the wall
when attaching it.
NOTICE
When you are installing the fesh-r everywhere®, now use the extract ducts to make a
connection to your in-house ventilation system. See for more information Appendix 15.2.

7. Seal between the EPP cover and the outer wall with outdoor silicone kit. Make sure
you use enough expanding foam . Make sure the connection between the pipes and
the outer wall is airtight. This will prevent air leaking.
g. 22 Seal between the EPP cover and the outer wall with outdoor silicone kit
6 Connect the fresh-r®electrically and test its functionality
DANGER
• Connecting the fresh-r®to the mains electricity supply must be done by a qualied
electrician.
• Risk for electric shocks or electrocution. Turn o the mains electricity supply in the
distribution box before connecting the fresh-r®electrically.
Do the following:
1. Turn o the main electricity supply in the distribution box before attempting to wire
in the fresh-r®.
2. Make the electrical connection while the fresh-r®is turned OFF.
The electric cable location is on the left hand top.
g. 23 Location of the electric cable
(outside of the house)

18
3. Turn the main electricity supply ON again at the distribution box.
4. Turn the fresh-r®ON and wait for approximately 1 minute while the unit boots up.
If you see three illuminated lights and notice fans running, the unit is properly
functioning.
If not:
Check the main electricity supply. If the product still does not work, turn the unit
OFF and contact your supplier.
7 Place the grilles assembly (nd the content in Bag B)
Do the following:
1. Mount the grilles on the outer face of the outside-wall.
2. Place the covers.
NOTICE
The lip of the lower duct pipe should overlap with the edge of the grilles cover so
condensate water is guided from the outer wall.
g. 24 Place the grid assembly

19
g. 25 Lip should overlap with the edge of the grilles
