APPLICATION FIELD OF “TERMOSPLIT”
TERMOSPLIT, the hot air generator device, can be used for heating large
environments where re risk activities are carried out or with relevant ow of
people.
The different models of TERMOSPLIT are composed of an external unit and an
internal unit that can be connected by a supplied kit.
The external unit provides the heat the internal unit will convey within the room
in total safety.
TERMOSPLIT doesn't need the Fire Department authorization even in case of
systems exceeding 100,000 kcal/h.

GENERAL WARNINGS
The instruction manual is an integral and essential part of the product and is supplied with every TERMOSPLIT Air Control.
Read carefully all the Warnings in the Manual as they provide important information on safe installation, operation
and maintenance.
Keep this manual for future reference.
- Installation must be carried out according to National and Local rules and laws by qualied personnel and following the
manufacturer's instructions.
- Qualied personnel refers to skilled technicians with specic expertise for the installation of heating systems for domestic use
and hot water production, as per Law No 46/90 of March 3rd 1990.
- The tasks the user can undertake are described ONLY in the chapter "USER INSTRUCTIONS".
The manufacturer does not accept any contractual or extra contractual liability for damage caused by wrong installation and
use and failure to comply with local and national applicable rules and the instructions provided.
- Always ensure the TERMOSPLIT packaging material (cardboard, nails, plastic bags, etc.) is out of reach of children as it is
potential source of danger.
- Before carrying out any cleaning or maintenance activity disconnect the appliance from the mains supply using the system
switch and/or the specic breakers.
- In case of failure and/or erratic behaviour, disconnect the appliance and avoid any repair attempt.
Only qualied personnel should perform service and maintenance on the TERMOSPLIT using genuine spare parts. Failure to
comply with such provisions may jeopardize the apparatus safety.
- In case you transfer the appliance to a new owner, please ensure to give him also the manual so he and/or the installer can
refer to it.
- The hot air generator TERMOSPLIT is only intended for the use it has been designed for. Any other use should be consider
incorrect and therefore dangerous.

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.
Fig. 12
Fig. 11
FLUE DUCT SELECTION
Similarly to all condensing appliances, TERMOSPLIT
KONDENS .14 needs approved ttings made of acid
aggressive resistance materials for fumes exhaust.
We suggest you to buy only genuine Air Control
parts.

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.
N.B.: We suggest to use anchors with threaded bar
(max M8) as shown in Figure 14.
