observing the safety distances between units and other equipment indicated below:
7
3 - INSTALLATION
3.2 HYDRAULIC AND REFRIGERATION CIRCUITS
The installer is responsible for the correct selection and application of components according to current national
standards and as recommended below.
3.3 HYDRAULIC COMPONENTS
The hydraulic connections are made on the fittings located on the right side of machine.
The hydraulic connections are distinguished by labels that indicate the flow: WATER INLET AND OUTLET
Provide and interception tap on the water inlet, use piping with an internal diameter that corresponds to the
diameter of the condensing unit's fittings because otherwise operation problems may result (the guarantee is
voided if improper piping is used).
WARNING: ALWAYS MOUNT THE INSPECTION FILTER ON THE WATER INLET
AND ENSURE THE CORRECT POSITIONING OF THE FILTERING UNIT
RESPECT MINIMUM DIAMETERS REQUIRED ON THE UNIT, CHECK THE WATER SUPPLY FLOW.
3.4 REFRIGERATION CONNECTIONS
The refrigeration connections are made on the fittings located on the right side of the unit. The connections on
the refrigeration lines are "flare” connections.
3.5 CONNECTIONS BETWEEN THE EVAPORATOR AND CONDENSING UNITS
The indoor unit must be connected to the condensing unit via Flare connections with a refrigerator quality
copper pipe at the ends of flare nuts and insulated along the entire length. It is absolutely necessary to respect
the
diameters
provided
on
IDRA INVERTER units
otherwise
the
guarantee
will
be
voided.
If
evaporator
units
with
refrigeration fittings different than those on the IDRA INVERTER units are used, use dedicated reduction connections
(attention: mount these fittings on the evaporator unit).
3.6 PIPE PREPARATION
Use only refrigeration quality copper pipes with a suitable diameter for each model. The gas and liquid
pipes must absolutely be insulated with insulation that has a minimum thickness of 6mm.
Insert the flare nuts on the pipe ends before preparing them with a countersink tool. The pipes, separately
insulated with the relative fittings can later be bound to the condensing unit's evacuation pipe and the
electrical cables using clamps.
3.7 PIPE ROUTE
The radius of curvature of the pipes must be equal or greater than three and a half times the diameter of the
pipe axis. Do not bend the pipes more than 3 times consecutively and not make more than 10 curves on the total
length of the connection. If there is more than a 5m difference between the evaporator unit and condensing
unit, a siphon must be placed at every 3 m. The siphon must have a radius of curvature that is as narrow as
possible.
3.8 AIR EXTRACTION IN REFRIGERATION AND
EVAPORTATOR PIPES
The R410a load is only contained in the condensing unit. The inner unit contains a small quantity of neutral gas.
Therefore, after having made the connections, it is necessary to extract the air contained in
these connections and in the inner units.
WARNING: IT IS NECESSARY TO USE A COUNTER KEY TO TIGHTEN THE VALVES.

3 - INSTALLATION
3.9 ASSEMBLY PROCEDURE
The IDRA INVERTER condensing unit MUST BE INSTALLED in an accessible place that allows for safe technical interventions;
if this is not the case, the Technical Assistance Centre may refuse intervention.
THE IDRA INVERTER CONDENSING UNIT MUST NOT BE INSTALLED OUTDOORS BECAUSE DURING
WINTER MONTHS ITS HYDRAULIC CIRCUIT MAY BE DAMAGED
ALWAYS PUT AN INSPECTABLE FILTER ON THE WATER INLET (500 micron mesh).
Connect the connection pipes to the condensing unit and the internal unit.
Connect the vacuum pump to the fitting (suction), start it up, and make sure that the indicator pointer goes
down to 0.1 Mpa (-760 mm Hg). Before disconnecting the vacuum pump ensure the vacuum indicator is stable
for >15 minutes.
Close the service valve and disconnect the vacuum pump.
Remove the caps from the "GAS" and "LIQUID" valves and open them with a hexagonal key to release the
R410a contained in the IDRA INVERTER, then put the caps back on.
Check that the connections are sealed properly .To do this use an electronic leak detector or a spray solution
for leak detection.
3.10 ADJUSTING THE REFRIGERANT LOAD
Depending on the connection length of each route, it may be necessary to top up the R410a load (the condensing
units are pre-filled with a line of 5 metres). This operation must be carried out by a qualified person who is an
expert in refrigeration. The complete load is introduced via the service valve or via the condensing unit's Flare
(large fitting). If the refrigerant line is less than 5 m “discharge" the quantity of excess refrigerant. All operations
involving refrigeration circuits require observing recommendation regarding the disposal of R410a
(according to local laws in force).
*See the technical data sheet.
3.11 ELECTRICAL CONNECTIONS
A proper and effective earthing connection is mandatory
;
the manufacturer is not responsible for damages caused by inappropriate or insufficient connections.
Electrical connections must be made respecting the following:
•
Use cables which are compliant with the laws in force in the different countries.
•
Follow the order of connection for the phase, neutral and earthed conductors.
•
Install a suitable protection and electric energy sectioning device with a delayed curve, a contact opening of
•
at least three millimetres and an adequate interruption and differential protection power.

3 - INSTALLATION
If the unit powering is three-phase, make sure to follow the exact sequence of the phases.
The supply voltage of the condensing unit must have a value between ± 10% of the value
indicated on the manufacturing data plate. If this is not followed, contact the local supplier of electric power.
In the case of three-phase power, the imbalance between the three phases should not exceed 3%.
Putting electrical connection cables inside the condensing unit in any part not approved by the
manufacturer is prohibited.
The power cable must be passed through one the holes with a rubber fairlead located on the left side of the
machine. The electrical connections are made on the terminal board located inside the components and
electrical compartment on the rear of the inspection panel.
Connect the cable to the terminals inside the electrical panel.
Absolutely avoid direct contact with metal parts.
Make sure, after the condensing unit has been operating for about 10 minutes that the screws on the power
terminal are closed.
Warning: Verify compatibility when using evaporator units NOT PROVIDED BY T.P.I.
The
connection between the
ventilation and
condensing
unit
requires
a
pentapolar
cable
(5 X
1.5
mm
q).
Power the IDRA unit with a cable suitable to the power consumption and install a properly sized general isolator
switch (in compliance with laws in force).

ADjUSTING
THE DIRECTION OFTHE
AIR FLOW
When you press the SWING vertic al bu t ton , the o sc ill ating v er ti ca l mov e ment o f the
directional flaps is enabled, when you press the SWING horizontal button ,the
oscillating
horizontal movement of the directional flaps is enabled To ensure the uniform
diffusion of
air throughout the room.
Press the AIR DIRECTION button again and the oscillating movement of the flaps stops in the
desired position and the air flow is directed in one direction only:
-we recommend you direct them upwards in cooling mode(to avoid having the direct flow of cool air).
-we recommend you direct them downwards in heating mode(as hot air tends to rise).
ATTENTION
-Unplug the appliance or switch off the dedicated switch before performing any operations
(risk of personal injury from electrocution).
-Do not direct the air flow directly towards people, artworks or animals (risk of causing
damage to things and personal injury to people’s skin)
-Do not insert or attempt to insert your fingers or various objects in the internal and external unit
air outlets and in the inlet grilles (risk of personal injury from cuts).
-Do not touch the air conditioning unit with wet hands (risk of electrocution).
ADVICE ON ENERGYSAVINGS
-Do not programme too high a temperature (in heating mode) or too low a temperature
(in cooling mode).
-Avoid installing the internal/external units in places directly exposed to sunlight(this
could prevent the appliance from operating at its best).
-Avoid opening and closing doors and windows too frequently, as the ongoing heat exchange
with the outside hinders the operation of the air conditioning unit.
-Use the “Timer” for the timed starting of the appliance to prevent the appliance from
opera- ting unnecessarily while you are out.· Use the “SLEEP” function at night.
ATTENTION
-Do not attempt to perform maintenance operations requiring the opening of the appliance
yourself: the presence of live elements and the gas contained n the cooling circuit
make these operations particularly dangerous (risk of personal injury from electrocution
and cold burns).
-When moving home, contact an authorised specialist.
Note:
-In cooling mode, you may detect a slight mist coming out of the Internal Unit for a few
seconds: this is completely normal and due to the difference in temperature between
the air exiting the appliance and the air inside the room.
-During operation, you may hear a noise similar to the flowing of water: this is completely
normal, owing to the liquid refrigerant flow ing throug h t he pipin g.
-When the air conditioning unit starts or stops, especially in heating mode, you may hear
a little creaking: this is due to the thermal expansion of the parts making up the appliance.
