RECOMMENDATIONS FOR INSTALLATION
Before installing the unit, ensure that:
1) The place of installation has sufficient space for carrying out installation as
well as routine and extraordinary maintenance work (see Pic. 3). If the unit is
installed behind a suspended ceiling, an access should be provided;
2) There are no obstructions for air intake and delivery;
3) The water fittings are of the sizes, in the position and spaced apart as required by the unit;
4) The system pressure does not exceed 8 bar for the water-filled versions;
5) The electricity supply corresponds to the data on the unit rating plate and that
there is a circuit breaker switch readily accessible to the user to cut off the power
supply whenever necessary;
6) The circuit breaker is in the OFF position so that there is no voltage on the
unit supply line.
Drill the holes in line with the relative slots for the 6 unit screw anchors (Pic.
4). Inject thermosetting resin into the holes and then insert the screw anchors
(Pic. 5).
Fix the threaded rods of the correct length to the screw anchors (Pic. 5) and
insert them into the relative slots (Pic. 6). After having created a slope (max. 3
cm/m) in the direction of the condensate outlet, lock the threaded rod with a nut
and check nut. To prevent possible noise being created by vibrations from the
unit, it is advisable to insert a vibration-damping joint.
Note: the screw anchors, threaded rods and whatever else is necessary
for accomplishing the installation are NOT included in the supply of the
air treatment unit.

HYDRAULIC CONNECTION
MAIN HYDRAULIC CONNECTION
CAUTION! Always use a wrench and counter-wrench for connection of the
coil to the pipes (pic. 25). If the valve is installed, suitably insulate the valve
body with insulating material (pic. 26).
Connect the water inlet and outlet pipes, observing the indications given on the
side of the unit. Correctly insulate the water supply pipes to prevent dripping
during the cooling mode of operation. A shutoff valve should be inserted on the
water supply pipe and a balancing valve on the outlet pipe. The valve body and
balancing valve should also be properly insulated to prevent dripping. It is the
installer’s responsibility to insulate properly and the manufacturer cannot be held
liable for any insulation work.
NOTE: It is always advisable to install the valve. In the heating mode of
operation the valve reduces consumption because upon reaching the set
temperature the circulation of water is stopped to avoid wasting energy
(the fan coil would otherwise continue to heat like a radiator, even with the
motor at a standstill). In the cooling mode of operation the valve stops the
circulation of water when the set temperature is reached, this stopping the
internal exchanger from continuing to condense water with possible
undesirable dripping onto the floor. It also reduces chiller operation with
consequent energy saving.
CONDENSATE WATER DRAINAGE
The condensate drain pipe should slope downwards by at least 3 cm/m and
should not have ascending or throttled sections in order to ensure a regular flow
of water. It is advisable for a trap to be fitted. The condensate drain pipe should
be connected to a rainwater drainage system. Do not use sewage systems to
avoid possible rising of smells in the event of evaporation of the water in the
trap. Upon completion of work, check that the condensate flows out properly by
pouring water into the tray. The condensate water drainage system should be
fabricated in a workmanlike manner and should be periodically checked.
The manufacturer cannot be held liable for any damage caused by dripping in
the absence of a valve or of periodic maintenance of the drainage system.
ELECTRICAL CONNECTIONS
RECOMMENDATIONS!
Before carrying out electrical connections, ensure that the electricity supply to
the supply line has been cut off, checking that the on-off switch is in the OFF
position.
- Only qualified electricians should carry out the electrical connections.
- Check that the mains supply is single-phase 230 Vac/1/50 Hz (± 10%).
- Operating the unit with voltages outside the above limits could cause malfunction and renders the warranty null and void.
- The power supply line should be fitted with at least a switch isolator in conformity with European standard EN60947-3.
- Make sure that the electrical system is suitable for providing not only the working current required by the unit, but also the necessary current for powering
household and other electrical appliances already in use. Any electrical and
mechanical alterations or tampering render the warranty null and void.
The cables should be sufficiently long so that they are not permanently taut or
create throttling or compression on metal parts.
The power cables should be sufficiently long so that in the event of accidental
tugging the active wires are subjected to stress before the earth wire. Connect
the earth wire to the relative terminal marked with the symbol . Comply with
the safety regulations in force in the country of installation.
CONNECTIONS TO THE TERMINAL BOARD
The electrical connections should be made to the terminal boards on the side of
the appliance. Each terminal is identified by the label to be found on the terminal
boards.
CAUTION! FAILURE TO COMPLY WITH THE INDICATED CONNECTIONS
MAY CAUSE MOTOR BURNOUT!

TURNING THE COIL
CAUTION
The fan wheels may reach the speed of 1,000 rpm. Do not insert objects into the
electric fan and certainly not hands. The motor becomes hot during operation;
wait for it to cool before touching it. During the heating mode of operation the
exchanger and the connecting pipes may become very hot (80°C). Wait for the
exchanger to cool before touching it or protect hands with suitable gloves. The
heat exchange water coils are suitable for working up to a maximum pressure
of 8 bar.
To turn the coil, proceed as follows:
1. Disconnect the terminal board (6) from the side of the unit.
2. Remove the condensate collecting tray (2).
3. Remove the coil fixing screws (5).
4. Take out the coil (3), being careful not to be cut by the fins and not to damage them.
5. Remove the knockouts (1) on the opposite side of the unit (using a screwdriver) to allow the coil connections to pass through.
6. Position the coil, turning it without tipping it upside down, so that the fittings
are in line with the holes left by the knockouts.
7. Fix the coil using the previously removed screws (5).
8. Shift the terminal board (fixing it to the side opposite the water fittings) and
the motor cables, fixing them with their clamps. Ensure that the cables pass
through the hole in the side of the unit, protecting them with the relative grommet. If it proves easier to carry out this operation by separating the wires from
the terminal board, mark the positions of the wires to avoid making mistakes
when reconnecting.
9. Reconnect the wires to the relative terminal board (6), taking care that they
are correctly positioned.
10. Replace the condensate collecting tray (2).
CLEANING AND MAINTENANCE
CAUTION
Before carrying out any cleaning or maintenance work, disconnect the
unit from the mains electricity supply!
ROUTINE MAINTENANCE
The user is duty bound to have all maintenance operations carried out by trained and qualified personnel only. If the unit has to be dismantled, protect hands
with work gloves.
Monthly checks:
- Ensure that the fan impellers are clean. If they are dirty, clean them by suction
so as not to damage them.
- Check the whole of the electrical part and in particular that the electrical connections are tight.
Yearly checks:
- Check the whole of the electrical part and in particular that the electrical connections are tight.
- Check the tightness of all the bolts, nuts and whatever else may be loosened
by the constant vibrations of the unit.
- Check the motor for dust, dirt or other impurities. Periodically check that the
motor works without unusual vibrations or noise and that the fan inlet is not obstructed, which could otherwise leading to overheating of the windings.
- Check the fans for dirt or any foreign matter.
CLEANING THE AIR FILTER
The unit is fitted with an air filter on the fan inlet. During normal operation the
filter holds back impurities in the air.
The filter should be cleaned periodically to keep its filtering properties and the
airflow to the fan unchanged.
It is advisable to clean the filter at least once a month, proceeding as follows.
1. Take out the filter.
2. Place the filter on a flat, dry surface and remove the accumulated dust with
a vacuum cleaner.
3. Wash the filter with water and detergent (no solvents).
4. Leave the filter to dry in a ventilated place in the sun.
5. Replace the filter when it is perfectly dry.
Please clean the air filter every working season of the unit or more frequently considering the unit activity.
NOTE: the filter may also be taken out from the side or from the top.
