According to the installation design, prepare the
gas supply line and the electric system as per values
shown in the data sheet.
When you have chosen the exact TERMOSPLIT
KONDENS .14 installation position, follow the
instructions below:
- Set the cardboard template onto the wall, at the
desired height and perfectly levelled; the template
in Fig. 5 shows the layout of the holes to be drilled;
- Remove the external unit plastic cover by
unscrewing the two xing screws "A" on both sides.
Remove the front casing by loosening the four clips
xing it to the frame (Fig. 6).;
- Measure the wall thickness at the Ø 85 mm hole
and cut the plastic Ø 80 mm pipe (5 cm longer)
provided, place it in the hole as shown in Fig. 7
and seal it with cement or silicone ash with the
internal wall;
- Place the external unit using proper anchors
and connect the two hoses to the threaded pipe
ttings located on the bottom left side, matching
the colours (Red and Blue), installing the seals
provided. (Fig. 8)
N.B.: The part to be connected to the external unit
is the one with the union elbow.
POSITIONING OF THE APPLIANCE
Before installing the appliance, you have to take
note of the minimum clearances necessary for the
TERMOSPLIT KONDENS .14 installation.
In addition to what shown in Fig. 4, you should also
be borne in mind that:
- Installing the appliance far higher than the
minimum required height is not advisable as it
makes difficult carrying out maintenance and
would require special equipment to work in safe
condition (e.g. scaffold or basket), moreover the
hot air tends to stratify towards the top;
- If the installation minimum required clearances
(shown next) are not met, removing some of the
components could be difcult.
EXTERNAL UNIT INSTALLATION
We suggest to install a destratication fan “MIXER”
to improve thermal comfort and reduce energy
consumption in high premises.

If a standard installation is not feasible as it is not
possible to drill a connection hole between internal
and external unit as per the cardboard template,
you can guide the two connection pipes and the
electrical cable through the bottom removing the
pre-cut slot (see Fig. 9).
You will have to use more ttings (not provided) and
a pipes and cable conduit for protection against
UV and weathering.
N.B.: Pay attention to the ow direction (delivery
and return).
TERMOSPLIT KONDENS .14 is already tted with a
condensate trap to avoid the combustion products
entering the environment it is installed in.
The boiler's connection to the condensate line must
be inspectable and must drain into the household
waste-water drainage system with a minimum fall
specied by applicable regulations. There must be
no points where standing water can form and no
narrowing which could impede the ow.
An open type connection must be used to ensure
that any formation of ice in the drainage system
does not impede the condensate ow. Fig. 10
shows how to connect the trap to the household
drainage system.
Reference standard UNI 11071.
The installer shall be responsible for installing a
condensate neutralisation system if necessary.

EXHAUST FUMES AND AIR INTAKE SYSTEM INSTALLATION
The external unit TERMOSPLIT KONDENS .14 comes
with exhaust fumes and air intake system on the
top (wall-mounted exhaust) (A).
If it is not possible a wall-mount exhaust or you
prefer a roof-mount exhaust (for exhaust pipes
max. length see Table on page 4) you need to do
the following:
- Remove the cover "D" from the external unit by
unscrewing the two xing screws located on the
side (D1);
- Drill, in the position shown in Figure 11, a hole with
a diameter suitable for a Ø 80 pipe;
- Remove the metal sheet "C" releasing it from
exhaust "A";
- Remove the plug "B" from the exhaust "A"
loosening the two side screws (Fig. 12);
- Reinstall the exhaust "A" by xing it with the metal
sheet "C" and replace the cover "D";
- Install a rubber rosette "E" onto the Ø 80 pipe;
- Insert the Ø 80 pipe in the exhaust "A" until it
reaches the stop. The standard front outlet will
close and the fumes will go out through the inserted
vertical pipe;
- Check the pipes for proper installation to prevent
rainwater inltration in the appliance;
- Reinstall the two side screws.

Installation of TERMOSPLIT KONDENS .14 is complete
when the two units are connected by means of
the electric cord and the delivery and return pipes.
Proceed as follows:
- connect the two pipes shown in Figure 15 to the
two valves "A" and valve "B", making sure to match
the relevant colours; open the two shut-off valves.
N.B.: In order to obtain a leak proof joint insert
the relevant TEFLON gaskets (included). Even
the slightest leak could prevent operation of the
TERMOSPLIT KONDENS .14 in a short time.
- You must now connect the two units using the
power cord built-in in the external unit.
N.B.: The two units can installed be as much as 30
metres max apart from each other (over 20 metres
a booster pump is required). The pipes size shall be
adapted accordingly and the uid relled (see the
technical data table on Page 4). The connection
cable can be ordered according to the required
length (max. 30 m.).
CONNECTION OF THE TWO UNITS
INTERNAL UNIT INSTALLATION
When you have chosen the installation position
of the TERMOSPLIT KONDENS .14 internal unit and
veried the corrected clearances as shown in Fig.
5 on page 6, you'll have to do the following:
- Remove the appliance from the packaging;
- Remove the two plastic sides;
- Following the guidelines on the cardboard
template, define the holes needed to fix the
TERMOSPLIT KONDENS .14;
- Position the cardboard template (see page 6);
- Drill the holes according to the anchors diameter
used;
- Screw a counter-locknut between the wall and
the mount bracket, then hang up the internal unit
and lock with a self-locking nut.
CAUTION: To avoid damaging the mount bracket,
do not over tighten the locknut if you don't have
inserted the counter-locknut.

CONNECTION TO THE TANK
In addition to the standards for the connection to
the methane gas network, you have to conform
to the following:
- Use only Teon or suitable sealant for ttings (do
not use hemp);
- Install a pressure reducer at the LPG tank
outlet calibrated to 1.5 bar and, before using
the appliance, install a second stage reducer
calibrated to a 30 mbar pressure for commercial
butane. When the installation is complete, always
check the seal as per UNI-CIG 7131 standard.
CONNECTION TO THE METHANE GAS NETWORK (G 20)
- According to the installation design, prepare the
gas supply line as per values shown in the data
sheet (see page 4).
- Connect the methane distribution network using an
appropriate pipe for the TERMOSPLIT KONDENS .14
consumption (see Figure 6 on page 7).
- Always install a shut off ball valve upstream of
the appliance.
- Check the inside of the pipe for contaminants
and, when the installation is complete, the tightness
as per UNI-CIG 7129 standard.
CARRIER FLUID FILLING
This activity must be carried out by the installer
during the appliance installation according to the
following instructions:
- Connect a loading pump to the valve;
- Open the valve;
- Ensure the automatic air vent valve plugs on both
units are open; Leave them open so the air in the
circuit comes out automatically. In the top part of
the unit there is also a manual bleed valve;
Fig. 16 Fig. 17
Once the installation is complete, and before
mounting the side panels of the internal unit, check
the circuit for uid leaks and that its pressure ranges
between 1.8 and 2.0 bars.
- Load the uid provided (pre-mixed 75% water +
25% glycol) until you reach about a 2 bar pressure;
- Close the valve and disconnect the pump.

TERMOSPLIT KONDENS 70 - I.S.P.E.S.L. SAFETIES
TERMOSPLIT KONDENS .14 70 is supplied complete
with all I.S.P.E.S.L. safety-related components, pre-
installed and certied, but the (mandatory) On/
Off valve.
The choice of this valve is at the discretion of the
installer, who shall provide the external mounting
of the device as shown in Figure A.
Each TERMOSPLIT KONDENS .14 70 comes with
the specic pit for installing the fuel On/Off valve
capillary (suitable to the CALEFFI valve mod.
541050).
N.B.: Certificates for the approved I.S.P.E.S.L.
components are included in the appliances
technical documentation.
CARRIER FLUID FILLING/TOPPING UP BY SELF REFILLING KIT
Relling the carrier uid is performed automatically
during the rst start-up of the appliance. In order to
do this, once the internal unit is installed, open the two
connection valves between the units (making sure no
leaks are present), pour the content of the included
uid can in the machine relling tank and power the
appliance On.
In case the pressure of the uid is lower than 0.9 bar,
the loading pump will start automatically, increasing
the pressure up to 1.8 bars within 5 minutes maximum.
In case the required pressure is not reached within 5
minutes, the pump will stop.
You must now verify the circuit for leaks and the relling
tank for full, then cycle power to the system for reset;
now the system should restart the automatic relling.
The automatic refilling process is set to start
automatically any time the internal circuit pressure
drops below 0.9 bars.
In case of failure of the loading pump or if you need
emptying the system, use the manual unloading/
loading valve provided.
Once the installation is complete, and before
mounting the side panels of the internal unit, check
the circuit for uid leaks and that its pressure ranges
between 1.8 and 2.0 bars.

FIRST IGNITION
GENERAL INSPECTION
Before performing the rst ignition (also known as
"rst ignition test") the local T.A.C. shall check the
appliance for correct installation. This check is
specically aimed at those conditions that could
endanger the safety and functionality of the
appliance. Therefore, it's quintessential that the
installation meets the minimum required height and
obstacles clearance, as shown in Figure 1 on page
6 and dened by UNI-CIG standards 7129/7131, Law
46/90 and CEI 648 standard.
Furthermore, you must check that the installation
has been performed as described in the AIR
CONTROL manual. In case the T.A.C. detects
any potential problem that may affect the
safety or functionality of the appliance, the
commissioning shall not be performed and the lack
of compliance communicated to the installer and
the manufacturer.
IMPORTANT: the first ignition MUST be solely
performed by an AIR CONTROL Authorized
Technical Assistance Centre.
ANALYSIS - CHECKING AND REGULATING COMBUSTION
The boiler comes already calibrated and tested for the
requested type of gas, however it is advisable to check
that the type of gas supplied in the mains and the supply
pressure are correct. If this should not be the case, follow
the procedures described in this section.
Using a pressure gauge connected to the gas valve"P"
pressure port (Fig. 31), check that the measured pressure
matches the values shown in the technical data table.
MAXIMUM POWER:
• Cut power to the equipment using the power switch
and open the instrument board by loosening the
cover 4 "A" screws (See Fig. 28).
• Set the A and B JUMPERS to ON (see Fig. 29) so that
the boiler ramps automatically to max. power at
restart.
• Close the instrument board, apply power, switch the
boiler On and set the fan in manual mode at max.
speed. Wait a few seconds for the ignition phase
to nish and the boiler to reach automatically the
max. power.
• Insert the combustion analyser probe in the
inspection outlet provided in the ue (Fig. 30). After
the boiler has been running for 2-3 minutes, run the
analysis and check that the CO2 measured by the
analyser corresponds to the value indicated in the
table for maximum power.
• If the CO2does not correspond, regulate with screw
"N" (Fig. 31) of the ratio adjuster until the specied
CO2 value is obtained. Turn clockwise to decrease
the CO2, value, anticlockwise to increase it.
MINIMUM POWER:
• Cut power to the equipment using the power switch
and open the instrument board by loosening the
cover 4 "A" screws (See Fig. 28).
• Set the A and B JUMPERS to OFF (see Fig. 29) so
that the boiler ramps automatically to min. power
at restart.
• Close the instrument board, apply power, switch the
boiler On and set the fan in manual mode at max.
speed. Wait a few seconds for the ignition phase
to nish and the boiler to reach automatically the
min. power.
• After the boiler has been running for 2-3 minutes, run
the analysis and check that the CO2 level measured
by the analyser corresponds to the level shown in
the table at minimum power.

CHANGING THE SUPPLY GAS
• If the CO2 level does not match, adjust it using
the screw "M" (Fig. 31) of the ratio adjuster, after
removing the protective cover "L" until the specied
CO2 level is reached. Turn clockwise to increase the
CO2, value, anticlockwise to decrease it.
Once the adjustments are complete it's advisable to
move the "A" and "B" JUMPERS to Off position (open);
screw in place the "L" protection cover; check if the
pressure outlet screw is tightened and the ue line is
perfectly leak proof. Restore the desired condition for
the fan.
It may be necessary to repeat the maximum and
minimum adjustment twice to obtain correct regulation.
