1. Introduction and safety
What is this unit for?
The Comfofond-L is a uid geothermal exchanger,
also known as a terrestrial heat exchanger. The
Comfofond-L heats or cools the outdoor air using
terrestrial heat. The heated or cooled outdoor air is
then led into the dwelling.
Function
1. Brine loop
2. Comfofond-L
3. ComfoAir Luxe
Brine loop pipes are laid in the ground and
connected to the dwelling. In the winter the cold
outdoor air is preheated, ensuring the ventilation
system continues to operate effectively even at low
temperatures. In the summer the warm outdoor air is
precooled.
The Comfofond-L is specially developed to operate
in combination with a Zehnder ventilation system
of type ComfoAir 350 Luxe or ComfoAir 550 Luxe.
The required pump control for the Comfofond-L is
integrated in this ventilation system as standard.
The ventilation unit installation manual covers
in greater detail ventilation issues and how the
ventilation system works. A copy of this manual can
be obtained from Zehnder.

3. Installation conditions and
dimensional sketches
In order to determine whether the Comfofond-L can
be installed in a certain area, the following aspects
must be taken into account:
• The Comfofond-L must be installed according
to the general and locally applicable safety
and installation regulations of power and water
companies, as well as the instructions in this
manual;
• The system must be tted to allow sufcient
room around the Comfofond-L and ComfoAir
Luxe for the air connections and brine loops as
well as for carrying out maintenance activities;
• The room must offer the following provisions:
- Air duct connections.
- 230V electrical connection.
- Provisions for the condensation drain.
- Brine loops for the pipe system.
• The Comfofond-L must be installed in a frost-free
space;
The fluid in the system may not freeze.
Irreversible damage will be caused to the
machine if the fluid freezes.
• The condensation must be drained off frost-free,
at a gradient, using a siphon;
• We recommend that the Comfofond-L is not
installed in spaces with a higher average
humidity (such as a bathroom or toilet). This is
to prevent the formation of condensation on the
outside of the Comfofond-L.
• An outer valve is a requirement if the system is
used in areas where the temperature is lower
than -15ºC. This valve must shut off the supply
air in the event of a power failure. The system
can be damaged during a power failure at
temperatures lower than -15ºC, this is why an
outer valve is a requirement.

4. Installation
4.1 Connecting the air ducting
Take account of the following factors when mounting
air ducting:
• Only use the supplied connecting material
between the Comfofond-L and ComfoAir Luxe;
• Insulate the outdoor air supply duct between
the roof-/facade duct and the Comfofond-L
vapour-proof. This prevents the formation of
condensation on the outside of the ducts;
• The air outlet on the Comfofond-L must be
connected to the outdoor air connection on the
ComfoAir Luxe;
• The air outlet on the Comfofond-L 350 is on
the side of the Comfofond-L at the top.
• The air outlet on the Comfofond-L 550 is on
the upper side of the Comfofond-L.
• The outdoor air must be connected to the air
inlet on the Comfofond-L. The air inlet on the
Comfofond-L is on the side of the Comfofond-L
at the bottom.

4.2 Wall mounting
Mount the Comfofond-L against a wall with a
minimum mass of 200 kg/m2. The Zehnder base
frame (optional extra) must be used for other walls.
This reduces contact noise as much as possible.
Comfofond-L 350 Comfofond-L 550
Make sure to leave a minimum space of 110 cm in
front of the Comfofond-L in view of the necessary
maintenance work.
Where necessary, reposition the ComfoAir
Luxe documentation to make sure it is still
accessible following the installation of the
Comfofond-L.

4.3 Connecting the condensation drain
Take account of the following factors when tting the
condensation drain:
• The condensation must be drained off frost-free,
at a gradient, using an appropriate siphon;
• Connect the condensation drain (air-tight) via a
pipe or a hose with a siphon (with a water seal of
at least 60mm) to the sanitary pipework;
• Position the upper edge of the siphon at least 40
mm underneath the condensation drain of the
Comfofond-L.
Comfofond-L 350
Comfofond-L 550
The condensation drains of the
Comfofond-L and the ComfoAir Luxe must
always be connected with a siphon.

EN 10
4.4 Connecting the brine loop (terrestrial
heat collector)
Insulate all brine loops (C) on the
brine loop. This prevents the formation of
condensation on the outside of the brine loop.
The Comfofond-L uses a terrestrial heat collector
which extracts heat from the ground and transfers
this to the air that ows through the Comfofond-L.
The terrestrial heat collector is formed by a PE pipe.
The length of the pipe is subject to local conditions,
such as the type of ground and the ground water
level. Solid ground contains more energy that loose
ground. If the pipe is below ground water level, then
substantial quantities of energy can be extracted at
the base.
The pipe must be horizontally positioned in the
ground (more or less) at an ideal depth of 1.5 to 2.5
metres, but certainly no deeper than 8 meters.
When calculating the length of the pipe, the actual
length for the calculation is the length that is
physically in the ground. The length inside the house
has no further effect on the energy that the system
can extract. The required pipe length for sandy soil is
twice as long.
The correct length of pipe can be
determined using the Comfofond-L
specifications. Zehnder has special software
available for calculating the required pipe
length.
The pipe can be laid in any random form. The
preferred situation is to lay the pipe in the ground
around the house and keep the length inside the
house to a minimum. In order to increase the
efciency, a minimum distance of 50 cm between
any loops in the pipe is advised.
Use an adaptor to connect one end of the PE pipe to
the uid connection inlet (A) of the Comfofond-L.
Use an adaptor to connect the other end of the
PE pipe to the uid connection outlet (B) of the
Comfofond-L.
Both connections are ¾” conical male-threaded.

Luxe connection printed circuit board
of the ComfoAir Luxe
Fluid pump
4.5 Electrical connections
The Comfofond-L is controlled and fed by the
ComfoAir Luxe. To do so, the temperature sensor
and uid pump of the Comfofond-L must be
connected to the Luxe connection printed circuit
board on the ComfoAir Luxe. This Luxe connection
printed circuit board is on the top of the ComfoAir
Luxe.
The temperature sensor must be connected to the
clamps that are marked with the text Tge and GND.
This sensor is not sensitive to direction. Therefore, it
does not matter which wire is connected to the Tge
or GND clamp.
The uid pump must be connected to the supply
block on the Luxe connection printed circuit
board. As the Comfofond-L pump is not constantly
operational, this is connected to a power supply that
is switched by the ComfoAir Luxe. This power supply
is on the clamp marked with the text C. (The E clamp
next to this is a constant power supply that is used
for lling the Comfofond-L).

EN 12
5. Commissioning
All loose parts, including cardboard and
packaging materials must be removed from
the system before commissioning.
5.1 Filling the brine loop

5.2 Adjusting the uid pump
The fluid pump supports two user modes.
The "constant pressure" mode is always
used on the Comfofond-L.
Variable pressure. Constant pressure.
The Comfofond-L uses a
uid pump to pump the uid through the brine loop.
This uid pump must be adjusted correctly to achieve
the best possible performance of the Comfofond-L
. The uid pump setting is subject to the ComfoAir
Luxe type:
- The uid pump for the Comfofond-L 350 must
achieve a ow rate of 6-8 litres per minute.
- The uid pump for the Comfofond-L 550 must
achieve a ow rate of 8-10 litres per minute.
The pump setting is subject to:
• the total length of the terrestrial heat collector;
• the internal diameter of the terrestrial heat
collector;
• the composition of the uid mixture;
• the temperature of the uid mixture;
The correct setting for the fluid pump can
be determined using the Comfofond-L
specifications.

6. Maintenance
Failure to carry out (periodic) maintenance
on the Comfofond-L ultimately compromises
the performance of the system.
To ensure a hassle-free lifespan for your
Comfofond-L, we recommend you take out a service
agreement with an expert company.
The following maintenance may be carried out
by the user:
• Replacing the lter;
• Cleaning the condensation drain;
• Checking the system pressure.
The following maintenance may be carried out
by the tter:
• Inspecting the brine loop;
• Cleaning the internal siphon;
• Inspecting and cleaning the Comfofond-L
casing;
• Inspecting and cleaning the Comfofond-L
battery;
• Replacing the uid pump (where required);
• Replacing the expansion vessel (where required);
• Replacing the lling valve (where required);
• Replacing the pressure meter (where required);
• Replacing the de-aerator (where required);
A concise explanation of these maintenance
activities is given in the paragraphs below.
Ensure the Comfofond-L has been
disconnected from mains power before
carrying out any maintenance work. To do
this disconnect the ComfoAir Luxe from the
power supply to which it is connected.
Bear in mind that the
brine loop is pressurised.
Only a recognized cooling-technology fitter
may top up the Comfofond-L or perform
maintenance on parts of the brine loop.
A maintenance log has been included at the
rear of this manual which can be used to
note all performed maintenance.
For maintenance of the ComfoAir Luxe, please read
the instructions in the ComfoAir Luxe manual. A
copy of this manual can be obtained from Zehnder.
