INSTALLATION

FIXING THE CASSETTE Select a place of installation where there can be a clearance of a least 140 cm around the appliance. Make sure that the installation does not interfere with existing electric wiring or plumbing. Establish the position and size of the hole in the ceiling using the cardboard mounting template.To fix the unit to the ceiling, use chains or steel lanyard and suitable screw an- chors as shown in picture (material not included in the supply).

Use a spirit level, to make sure that the unit is level and check that it is securely fixed to the ceiling. In high humidity environments, metal  supports must be insulated using adhesive insulating material.

FIXING THE PANEL After installation of the unit, mount the grille using the 4 screws provided.
ATTENTION: It is very important to fix the grille in the right position for correct connection of the receiver panel to the unit.

• To fix the panel only use the 4 supplied screws. Do not use other kinds of screws or you could damage the condensate drain pan.
• Do not bend or narrow the unit piping.
• Do not remove the cap from the unit piping until immediately before connecting the pipes.
• To prevent deformation of the air intake grille, do not overtighten the screws.

CHANGE OF AIR AND RECIRCULATION SYSTEM

• Side knockouts allow connection of a duct for fresh air intake and for conditioning an adjacent room.

FRESH AIR RENEWAL

Remove the knockout holes and the insulation. The ducts may be in flexible polyester (with steel spiral core) or in corrugated aluminium lagged with anti-condensate material. Upon completion of installation, surfaces that have not been insulated may be covered with anti-condensate insulating material (e.g.: 6 mm thick expanded neoprene).

WATER CONNECTIONS

STANDARD WATER CONNECTION TO HEATING/ COOLING SYSTEM
ATTENTION! IT IS COMPULSORY TO INSTALL THE VALVE!
The following reasons explain why it is necessary to install the 3-way valve:

– Cassettes with a control board onboard

1. If the water flow is not closed via the valve when the room temperature is reached, the air sensor installed in intake mode is conditioned by  the heat exchanger that cools it or heats it via natural convection. The result is that the unit will not adjust the temperature correctly or it will not go on.

2. The unit has a protection system that intervenes by closing the water flow via the valve in cases such as:
   a) Where there is a condensate discharge problem (if the valve does not close the water flow, the battery will continue to condense, causing the condensation basin to overflow).  b) The user inserts the incorrect function on the remote control: hot as opposed to cold.
   c) The water temperature rises to 70 °C (which damages the main condensation basin)

3. The unit has been developed to heat and cool the environment by means of water flow control: this allows for optimal adjustment inside the room where it is installed.
   – Cassettes with and without a control board onboard

4. If the unit remains turned off for a long time in cooling mode and the water flow is not closed, droplets of condensation may form at the air outlets, which will subsequently lead to a dripping unit.

ATTENTION!
– Always use suitably sized wrenches to fix or slacken the water pipes.
– It is essential to insulate pipes, valves and connections correctly in order to avoid the formation of condensation, which could drip into suspended ceilings causing considerable problems.
The water connections are fixed to the unit body to avoid damage when pipes are connected. It is advisable to tighten the connection with a wrench. The upper coil connection is fitted with an air valve and the lower connection with a drain valve, suitable for a 10 mm wrench or screwdriver. (The coil is only partially drainable; it is advisable to blow air into the coil for complete drainage)

INSTALLATION OF AUXILIARY DRAIN PAN

a) Remove the plastic cap from the condensate drain outlet on the water cassette. Do NOT push the cap into the cassette.
Fit the nozzle into the hole (auxiliary condensate drain pan outlet).
b) Fix the auxiliary drain pan to the unit using the relative screws provided in the kit, ensuring that the condensate pan is level.

CONDENSATE DRAINAGE

ATTENTION!
CONDENSATE DRAINAGE IS FUNDAMENTAL FOR GOOD OPERATION OF THE WATER CASSETTE.
LAG THE PIPES SUITABLY AND CORRECTLY.
To ensure a correct flow of the condensed water, the water drainage pipe must have a slope of 3% without obstructions. Install a trap at least 50 mm deep in order to avoid unpleasant
smells.
To drain the condensate at a higher level, install condensate drain pump with collecting tray and float valve (not included in the standard accessories).
A float valve is recommended to stop the flow of water in the event of pump failure.
When several units are installed near to each other and only one condensate drain hose is used, make sure that the capacity of the hose is sufficient and that it is positioned on a slightly lower level than the appliance.
The condensate drain hose should be fixed using intermediate mounts to prevent deformation of the hose. The drain hose should slope slightly downwards to encourage drainage of
the condensed water.
The drain hose is bent or points upwards.
Keep difference in height between the drain hose and the unit.

ATTENTION!
– Ultimately verify the smooth flow of condensate water from the basin to the discharge pipe (before blocking the dropped ceiling)!
– If the condensate drainage alarm is activated, the zone valve is closed and the fan turned off. 50

Maintenance operations can be even simpler and faster thanks to the Easy Way System above all when unit is installed in modular false ceilings, allowing an excellent accessibility to all the main components in need of ordinary or extraordinary maintenance, thanks to an easily removed side panel that allows to avoid the typical procedure to remove grill, filter and main drain pan.
Once the side panel is removed the main components such as the valves, condensate drain pump, float, main drain pan and all the electric cabling can be easily accessed.
The Easy Way System system guarantees the possibility to work on the unit from the side rather than from below, with remarkable advantages for the maintenance operator.
After maintenance operations, install the front panel.

Inspection openings
If the false ceiling is not made with modular panels (tiles) and support frames such as to allow access, inspection hatches must be made on the sides indicated in the drawing according to the model, such as to be able to reach and operate on the hydraulic and electrical connections of the unit.

ELECTRICAL CONNECTIONS

ACCESS TO THE CONTROL PANEL
The electrical connections must be carried always on the terminal board

ATTENTION! Before carrying out electrical connections, ensure that the electricity supply 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 appliance with voltages outside the above limits could cause malfunction and renders the warranty null and void. Any electrical and mechanical alterations or tampering render the warranty null and void. The motor and accessories power cables in channels or conduits should remain inside the same until they are inside the appliances. The power supply line should be fitted with at least a circuit breaker complete with residual current circuit breaker according to European standards.

UNIT WITH ECM MOTOR
Realize a dedicated power supply line to the water cassettes equipped with a class A circuit breaker.
Install a 30 mA residual current circuit breaker for every 4 cassette units.
A larger number of units connected to the same RCCB does not guarantee a correct operation.
In the RC type cassette unit, the onboard control manages the ECM motor rotation speed, the control of the water inlet valves, the control of the room temperature.
In the NC type, the control of the rotation speed of the ECM motor and the valves is entrusted to an external control / thermostat (by the customer).
The external control / thermostat must have a 0-10Vdc proportional output signal for the ECM motor rotation speed and a 230 Vac on / off signal for controlling the water inlet valves to the cassette unit.

CHANGING THE MOTOR SPEEDS OF ROTATION

UNIT WITH 3 SPEED ASYNCHRONOUS MOTOR
The water cassette motor has 6 speed settings, 3 of which are connected in the factory. To use other speeds than those wired up in the factory, the minimum, medium and maximum wires may be connected onto 3 of the 6 numbered terminals (1…6), taking into account that the speeds follow a sequence as shown in the diagram.

CAUTION! UNDER NO CIRCUMSTANCES SHOULD THE CONNECTIONS TO THE TERMINALS L, M, M BE CHANGED!

MASTER-SLAVE FUNCTION

The master-slave function is done with connections and settings of the dip switches on the print circuit board One master and up to 30 slaves.
The information that is transferred from the master board to the slave boards are:

• ON / OFF
• Operating mode (heating-cooling-fan only)
• Fan speed (max-med-min-auto)
• Room temperature setting (set-point)

NOTE

1. The window contact function is not transferred from the master board to the slave boards

2. The information is transferred from the master board to the slave boards at each: – Remote control or wall interface command.
   – Cut off the power supply.

3. The slave boards can be managed locally with the infrared remote control, but in any case resume the commands from the master board at each:
   – Command given to the master board by remote control or wall interface – Cut off the power supply.

4. The commands given to each indivi- dual slave board do not pass to the master board and neither to the other slave boards.

RS485 COMMUNICATION NEWORK
Cable definition
Use shielded twisted cables for RS485 network consists of one or two twisted pairs and screens with the following characteristics:

• Impedance 120 Ohm at 1 MHZ

• Max capacity 50pF/m
  Example:

• Belden 3106A

• Belden 9841

Wiring scheme
Connect all devices by “daisy chain” topology.
Network limitations
The network should not be longer than 300 meters (longer distances to be covered by means of repeaters). The maximum amount of units per network should be not more than 60 units.
Installation remarks

• When pulling the cable, do not use force that may stretch the cable and distort its insulation and transmission properties.
• Do not allow the cable to kink, knot, snag, or fray when rolling it out or securing it.
• Do not splice cable segments. Use continuous runs of cable from one devi- ce to another.
• Do not cinch cables ties too tightly. Do not crush cables when securing them with staples or supports.
• Maintain the color-coding of all cabling throughout your system.
• Maintain wire twisting and run the cable jacket as close as possible to the termination point.
• Install cables and controllers to minimize the possibility of accidental contact with other, potentially hazardous and disruptive power and lighting cables. Do not run communication cables in the same conduit of electrical cables and if you cross an electrical cable, cross at a 90° angle.
• Do not place communication cables near other bare power cables, lightning rods, antennas, transformers, steam or hot water pipes, in any conduit, box, channel, duct or other enclosure containing power or lighting circuits of any type. Keep communication cables and controllers at least 2 meters from large inductive loads (power distribution panels, lighting ballasts, motors, etc.).

Addressing
Use the “MAC ADDRESS SW2” table to define the network addresses of the devices.
Termination
First and last devices in the communication line should be terminated with a 120 Ohm resistor to prevent signal reflection. When applicable, use the “end of line” jumper JP2 for this purpose.
Grounding
Connect one end of the shield (at the end of the communication line) to a tested ground (earth). Leave the other end of the shield not connected (floa- ting).

WARNINGS
Read the precautions carefully and carry out the procedures correctly:

• In case of failure or malfunction, always apply to authorised service personnel. Any attempt to remove parts, or to maintain the appliance can expose the user to danger of electrical shock. The cassette does not contain parts on which maintenance can be carried out by the user.
• In case of relocation, apply to service personnel authorised to carry out this operation as well as the new installation.
• Do not insert fingers or objects of any kind into airflow outlets or air intake grilles. There is a fan inside the appliance, which turns at high speed and could cause severe personal injury. Pay particular attention to children. – Do not allow the cold airflow to blow on you directly for long periods of time. Direct and prolonged exposure to cold air can be dangerous for your health. Pay particular attention to rooms where there are children, aged or sick people.
• In case of air conditioner malfunction (e.g. smell of burning), stop appliance operation immediately, release the dedicated automatic switch and apply to authorised service  personnel. Prolonged use of the appliance in these conditions can cause fire or electrocution.
• During installation of the appliances, avoid letting children or disabled have access to the working area. Accidents can occur.
• Install the appliance and the remote control at least two meters away from television or radio units and from lamps that could irradiate them directly. Any optical and radio interference can cause operating problems.
• Do not block or cover the airflow intake and delivery grilles. The obstruction of these openings causes a reduction of the operating efficiency of the water cassette, with consequent possible failure or damage.
• Do not use the water cassette for applications such as the storage of foods, plants, precision equipment or works of art. The quality of the objects that are stored could deteriorate.
• Do not expose animals or plants to the direct airflow from the appliance. Prolonged direct exposure to the cold airflow from the water cassette can have a negative effect on animals and plants.
• Do not direct the airflow of the air conditioner towards fireplaces or other heating appliances. An airflow directed towards the fire can cause incorrect combustion and fire.
• Do not allow the air conditioner to come into contact with water. The electrical insulation could be damaged with consequent possible risk of electrocution.

RECOMMENDATION

• Check installation conditions in order to identify possible damage.
  After prolonged use, apply to specialised service personnel to control the installation conditions of the air conditioner.

• Do not use flammable gas near the air conditioner.

• Always use the appliance with the air filter installed. Using the air conditioner without the air filter can cause an excessive accumulation of dust or deposits inside the unit, with consequent possible malfunctioning.

• Release the “automatic” switch if the unit is not going to be used for long periods of time.

• Remove the batteries from the remote control if it is not going to be used for a long period of time. Remove the batteries in order to prevent possible problems caused by loss of electrolyte. In case of accidental contact of the battery liquid with the skin, eyes or mouth, wash the affected part immediately with plenty of water, and see a doctor.

• During normal operation please shut off the unit ONLY using the ON/ OFF switch (infrared or wall-mounted remote control).

FAILURE TO COMPLY WITH THE INSTALLATION INSTRUCTIONS GIVEN IN THIS MANUAL RELIEVES THE MANUFACTURER OF ALL AND ANY LIABILITY. INCORRECT INSTALLATION COULD CAUSE MALFUNCTIONING OR FAILURE OF THE APPLIANCE. IT COULD ALSO REPRESENT A HAZARD FOR THE USER.

Run the timer

• Press 4 times the [Select] button – TIMER will blink
• Select TIMER ON ( ) or OFF ( ) using the [+] or [-] buttons.
• Press the [On/Send] button to send the information to the unit.

EMERGENCY ON/OFF BUTTON
The IR receiver contains an [On/Off] emergency button which can be used for turning the system ON and OFF when the IR remote control is not in hand. The [On/Off] button should be pressed for more than 3 seconds and until the unit beeps (but not more than 10 seconds). Once pressed, the unit will turn ON or OFF. When turned ON using the emergency button, the unit will operate in Auto change over mode using preset set-point temperatures for heating (21°C) and cooling (24°C). The fan will run in medium speed.

AIR TEMPERATURE SENSOR RECALIBRATION
Use the offset feature in stand alone configuration, when there is no wall panel, usisng the I.R. handset.
The technician will measure the actual room temperature (according to which he would like to make the offset for T1).
In order to update the offset, the following steps must be followed:

• with the unit ON press and hold the emergency button [located on the receiver] for more than 15 seconds. The system will enter to a “Calibration” mode. In this mode the beeper will beep each 5 seconds, and both blue and red LED’s will flash together and beep sound will continue until out of the calibration mode.
• Once the system is in “calibration mode” the technician will adjust the set point in the remote control as the measured actual room temperature, and send to the IR receiver [SEND].
• This temperature will be read, and the difference form the actual T1 measurement will be calculated into an offset of T1 = “Return Air Sensor Calibration”, and accordingly the parameter will be updated.
• If no information is sent from the remote control, after 2 minutes from the start of “calibration mode”, the system will automatically return to normal operation mode.
• After the technician has sent the “calibration temperature ”for the permanent saving of the data, switch OFF and ON, from the remote control, the unit.

FINS POSITIONING
AUTOMATIC POSITION
The unit (model RC only) automatically placed the blades according to the mode of operation. In cooling mode the blades remain in parallel position to exploit the benefits of the Coanda effect; in heating mode are positioned with an opening of 30° in order to exploit the effect of anti-stratification.
In the event that the automatic mode (marked by the symbol in the remote control) has been modified in manual mode (symbol ), to return to the standard defined by the manufacturer proceed as follows:

• Press the [Select] button 5 times (the icon will flash).
• Press the [-] button to select auto swing ( ).
• Press the [On/Send] button to send the  information to the unit. In this way the blades will set the automatic position established by the manufacturer.

INVERTED POSITION
If there is the need to change the inclination of the blades manually, to change the air flow differently from the standard position set in automatic way, proceed as follows:

• Press the [Select] button 5 times (the icon will flash).
• Press the [+] button to select manual swing ( ).
• Press the [On/Send] button to send the information to the unit. In this way the blades will reverse their position respect to automatic version.

BATTERIES REPLACEMENT

When the batteries are low, the display of the remote control will decrease. If the batteries will not be replaced the display will turn off completely.

Batteries replacement:

• Pull the batteries cover down to reveal the batteries.
• Remove the old batteries.
• Wait for 10 minutes before installing the new batteries.
• Install two new AAA batteries – Pay attention to the polarity.
• Return the batteries cover to place.

To prevent liquid leakage, take out all batteries when the remote controller is not going to be used for a long time.

ORDINARY MAINTENANCE

We always recommend to clean the air filter and the auxiliary drain pan at the end of the first start of the system, this is usually because the filter and the basin has accumulated dusts from the construction site. Thereafter, the frequency of cleaning should be established according to the work environment.

ATTENTION!
Turn off the automatic circuit breaker before carrying out any cleaning operations. Use a cloth dampened with lukewarm water (max 40°C) and mild detergent to clean the cassette. Do not use solvents or harsh detergents.

AIR FILTER MAINTENANCE
REMOVING THE FILTER
Opening the panel

1. Open the panel by unscrewing the two screws.

2. Pull the panel downward, without forcing the hinges that fasten it to the appliance.

3. Remove the “stop-filter” seal with a screwdriver.
   IMPORTANT!
   Place again the “stop-filter” seal when the filter comes reinstalled on the unit.

4.  Extract the filter pushing up the tab.

N.B.!
NEVER OPERATE THE CASSETTE WITHOUT THE AIR FILTER!

FILTER CLEANING
The filter must be clean with vacuum cleaner and wash with lukewarm water and mild detergent. Make sure the filters are dry before replacing them in the appliance.

ATTENTION!
Do not expose the filters to sunlight!

END OF SEASON MAINTENANCE

• Clean and replace the filters.
• On a sunny day leave the cassette running in fan mode for a few hours to allow the inside of the unit to dry completely.
