2.1 Importantinformaon
ATTENTION!!
The use and the maintenance of the KITA - AIR Templari®
heat pump, are subjected to the juridical ordinances of the
desnaon country. Depending on the amount of refrigerant you
need to check and note the ghtness of the heat pump at regular
intervals referring to qualied personnel.
• During transport it’s possible lt the external unit not over
45° (in any direcon).
• Transport protecon must be removed before to
commissioning.
• Don’t cover or reduce the sucon area.
• Comply with the building regulaons specic to individual
countries.
• If the heat pump is installed near the wall, be careful to the
inuence of building physics factors. Make sure that there
aren’t windows in the fan discharge area.
• If the heat pump is installed near a wall, there is a higher
risk of deposit of impuries. Besides, external air moved
by the heat pump must escape in order to not increase the
building thermal losses.
• It Is not allowed the installaon of the external unit or of
the monoblock in niches or in interior courtyards, because
the cooled air accumulates on the ground and in the case
of prolonged funconing would aspirated again by the heat
pump.
• The frozing limit can change depending on climate region.
Respect the regulaons of the countries concerned.
• Observe correct rotaonal direcon: in case of incorrect
wiring the start of the heat pump is hindered. The unit
presents a phase monitoring that indicates the correct
connecon.
• The heat pump could stop operaons in case of too low
external temperature. In case of long me power cut,
please see the commissioning procedure explained
forward.
• Before opening the device, make sure to switch o all the
electronics.
• Only qualied sta of the customer service can operate on
the device.
2.2 Proper use
KITA - AIR Templari® heat pump is homologated only for the
expected use, and it must be used as described by this manual.
A dierent ulizaon mode is considered non-compliant. Any
modicaon of the device is forbidden.
2.3 Regulatory
This device, in accordance to the 1st arcle of the 2006/42/ CE
Direcve, must be use only in residenal environment, and hence
is subjected to the 2006/95/CE Direcve (Low voltage supply).
For design and realizaon of the heat pump all the CE direcves
and all the DIN and VDE have been observed.
The electric connecon of the heat pump must be made in
accordance with the VDE, EN and DIN specicaons. Besides, the
specicaons for the electrical connecons xed by the supplier

diseases or lack of experience can’t use the device in safe,
mustn’t use the device without an expert guide. Make sure that
children don’t play with the heat pump.
2.4 Energecsaving
KITA Templari® contributes to environmental saving. To properly
ulize the thermal energy contained in the air, make sure of a
correct disposion of energy sources and plant. In order to
obtain an high energy eciency is necessary to reduce as much
as possible the temperature dierence between the external
air and internal air. For this reason a correct sizing and design
of the plant is recommended. Foratemperaturedierenceof
1°Chigher,itmeansanincreaseinconsumponof2,5%. Avoid
to place the internal unit inside dusty ambients. The dust may
accumulate on the heat exchanger decreasing its eciency. The
same in the case of corrosive volale substances.
3 Expected use of the heat

NOTE: the parameter equivalent lenght has to consider the
curves too. Each 90° curve in the circuit has to be counted as
a 1 m straight poron. Each 180° curve in the circuit has to be
counted as a 2 m straight poron. Each oil trap in the circuit has
to be counted as a 4 m straight poron.
8.2 Preparaonforinstallaonand
refrigerantpipelinesinstallaon
The coolant pipes connecons must be sealed to prevent
leakage of the coolant and the consequent malfunconing of the
heang pump. The connecon pipes must be insulated and have
diameters specied in the following table.
Gas (mm) Liquid (mm)
KITA AIR Ø 28 Ø 16
For the preparaon of the pipes for installaon, proceed as
follows:
• Measure the distance between internal and external units,
and perform all necessary installaon curves..
• The laying of the pipes must include the minimum number
of bends, because each curve increases the pressure drop
of the circuit and reduce the machine performance.
• Cut the pipes to a length slightly greater than that
measured.
• Completely remove smudging from the cut secon, holding
the pipe downward and blowing air into the pipe.
• Respect the safety measures that are indicated into the
table, or add the request quanty of refrigerant.
• Weld the provided manufacturer’s anchors at the end of
the connecon pipe. Weld the inner side female anchors
and the outer side male anchors. Where is possible,
perform welding in nitrogen atmosphere. Otherwise at the
end of welding operaon blow the nitrogen braise points..
• Insulate carefully the refrigerant anchors and connecons.

8.3 Vacuum procedure
• We recommend to run a leak test with nitrogen to 40 bar
pressure to check the quality of the welding connecons
• For the vacuum perform, connect the pump charging
vacuum connecon procedure (1/4) inside the external
unit.
• Perform the vacuum unl reaching 0.4mbr pressure
(duraon of procedure for about 1 h for 15m total length
connecon. If the length increases as result will increase
duraon of the vacuum perform).
• At the end of the procedure remove the pump and open
the valve to pour out the refrigerant liquid.

9 Maintenance and cleaning
A regularly maintenance is necessary in parcular for correct
and ecient heat pump operaons, so as to reduce damages
and usury of the components. The user decides the maintenance
frequency. It depends in parcular on two factors:
• The ulizaon mode: if the operang mode during the year
is single (heat pump or chiller), an annual maintenance is
suggested; if the operang mode is double (heat pump
and chiller) during the year, the maintenance shall be
halfyearly.
• The installaon place: if the installaon is located in heavy
polluted places or in the presence of dust that could
obstruct the nned coil, it is suggested to frequently check
the nned coil condions and, if necessary, to supply a
more frequent maintenance.
WARNING!
Disconnect the device from the electric supply before every
operaon to avoid injuries due to the acvaon of some
parcular operang logics.
9.1 Finned coil cleaning
During the machine funconing it’s possible that the nned
baery will parally obstructed because presence of leaves or
incrustaons of various kinds, also provoking a malfunconing of
the heat pump. It is possible then clean the baery with a under
pressure jet of air in a parallel direcon of the ns, you should
also remove any deposits in the baery compartment keeping
an adequate distance so as not to risk to fold or damage them.
• Clean the frontal surface;
• Remove the panel on top as shown by the gure.
• clean also the internal unit nned baery, especially if it is
placed in dusty ambient
WARNING!
Don’t touch the ns to avoid to be cued. Don’t fold the ns, this
could reduce the performances. In case of folded ns, contact a
service center.
9.2 Condensate discharge cleaning
Please make sure that the condensate discharge pipe is in the
correct posion e without any obstrucon to ensure a proper
condensate ow from the nned coil ns.
9.3 Refrigerant circuit maintenance
The machine is equipped with a safety valve which ensure
the reducon of internal refrigerant circuit pressure in case of
external generaon of heat (e.g. in case of re).
To ensure proper operaon of the valve, contact the manufacturer
and make sure to replace it each 4 years.
WARNING!
The direct contact between the skin and coolant out of the safety
valve cause serious injury. Do not stand near the valve.

10 Electricconnecon
10.1 Generalinformaon
• Before starng any operaon please adopt any safety
device and make sure that the unit is in stable equilibrium
and that there isn’t any element connected to the electric
supply.
• The electric supply line must adopt safety devices suitable
for the machine characteriscs that can interrupt the
hortcircuit current.
• Refer to the electric diagram of the unit.
• At rst please connect the grounding connecon.
• Before switching the unit on, all protecons must be acve.
10.2 Operaonsoflaying
• Please install cables far from lines with dierent voltage or
from devices that can create electromagnec interferences.
• Avoid parallel laying with other cables, the arrangement is
only permied at 90 °
• Pass the power cables and the net control cable of the
machine only trough proper holes.
10.3 Externalunitconnecon
• Connect the power supply to the external unit electric
terminal by the following table named “power supply
cables indicaon“. Cables passage takes place through the
apposite holes.
• See 12.1 for the connecon of drain pan’s electric heater.
10.4 Internalunitconnecon
• For electric connecon see the following table named
“power supply cables indicaon“. See the chapter 11 the
terminal picture where to connect RS485 fan contacts (2 core
cable) and the sensor probe (2 core cable). The cable carries
low voltage control signals: nd a route far from sources of
interference, do not joints along the way, possibly using a 3
core cable + shield secon 1.50 sq mm (shield connected to
GND to indoor unit side).
• Connect the internal unit 230V fan power supply ( phase,
neutral, ground) to the terminal board of the external unit
through the tripolar cable (minimum secon 1,5 mmq).
• Pay special aenon on ground connecon: the GND
must be the same for the 2 units. ABSOLUTELY AVOID THE
CONTACT BETWEEN THE SIGNAL GND AND THE THE GND OF
POWER SUPPLY!
WARNING!
The secon of the supply cables is to be considered indicave
and relave to the last part of the line towards the machine, that
should be as shorter as possible. The external protecons, the
posion and cable secon of the previous supply line should be
sized and realized by an authorized person and according to the
technical standards of the naonal authories.
10.5 Probes and remote controller
Temperature probe B2 of internal ambient temperature must
be connected with a mulpolar cable (2x1,5 shielded) along
the shortest route and away from the power cables. Parcular
aenon should be paid to the juncons because of parasic
resistance inuence which may compromise the Control Board
value readings.
Connect the remote panel with a telephone cable to the external
unit. The remote panel and the probes cable can be laid together
with the same precauons.
WARNING!
We recommend to use a ferrite Toroid to protect the remote
panel from any external disturbance.
