IMPORTANT!

Please read before installation

This air conditioning system meets strict safety and operating

standards.

For the installer or service person, it is important to install or

service the system so that it operates safely and efficiently.

For safe installation and trouble-free operation, you must:

• Carefully read this instruction booklet before beginning.

• Follow each installation or repair step exactly as shown.

• Observe all local, state and national electrical codes.

• Pay close attention to all warning and caution notices given in

this manual.

•The unit must be supplied with a dedicated electrical line.

This symbol refers to a hazard or unsafe practice which can result

in severe personal injury or death.

This symbol refers to a hazard or unsafe practice which can result

in personal injury or product or property damage.

If necessary, get help

These instructions are all you need for most installation sites and

maintenance conditions.

If you require help for a special problem, contact our sale/service

outlet or your certified dealer for additional instructions.

In case of improper installation

The manufacturer shall in no way be responsible for improper

installation or maintenance service, including failure to follow the

instructions in this document.

SPECIAL PRECAUTIONS

• During installation, connect before the refrigerant system and

then the wiring one; proceed in the reverse orden when removing

the units.

When wiring

ELECTRICAL SHOCK CAN CAUSE SEVERE

PERSONAL INJURY OR DEATH. ONLY A QUALIFIED,

EXPERIENCED ELECTRICIANS SHOULD ATTEMPT

TO WIRE THIS SYSTEM.

• Do not supply power to the unit until all wiring and tubing are

completed or reconnected and checked, to ensure the grounding.

• Highly dangerous electrical voltages are used in this system.

Carefully refer to the wiring diagram and these instructions when

wiring.

Improper connections and inadequate grounding can cause

accidental injury and death.

•Ground the unit following local electrical codes.

• The Yellow/Green wire cannot be used for any connection

different from the ground connection.

• Connect all wiring tightly. Loose wiring may cause overheating

at connection points and a possible fire hazard.

• Do not allow wiring to touch the refrigerant tubing, compressor,

or any moving parts of the fan.

• Do not use multi-core cable when wiring the power supply and

control lines. Use separate cables for each type of line.

When transporting

Be careful when picking up and moving the indoor and outdoor

units. Get a partner to help, and bend your knees when lifting to

reduce strain on your back. Sharp edges or thin aluminium fins on

the air conditioner can cut your fingers.

When installing...

... In a ceiling or wall

Make sure the ceiling/wall is strong enough to hold the unit-weight.

It may be necessary to build a strong wooden or metal frame to

provide added support.

... In a room

Properly insulate any tubing run inside a room to prevent

"sweating", which can cause dripping and water damage to walls

and floors.

... In moist or uneven locations

Use a raised concrete base to provide a solid level foundation for

the outdoor unit.

This prevents damage and abnormal vibrations.

... In area with strong winds

Securely anchor the outdoor unit down with bolts and a metal

frame. Provide a suitable air baffle.

... In a snowy area (for heat pump-type systems)

Install the outdoor unit on a raised platform that is higher than

drifting snow. Provide snow vents.

When connecting refrigerant tubing

• Keep all tubing runs as short as possible.

• Use the flare method for connecting tubing.

• Apply refrigerant lubricant to the matching surfaces of the flare

and union tubes before connecting them; screw by hand and

then tighten the nut with a torque wrench for a leak-free

connection.

• Check carefully for leaks before starting the test run.

NOTE:

Depending on the system type, liquid and gas lines may be either

narrow or wide. Therefore, to avoid confusion, the refrigerant

tubing for your particular model is specified as narrow tube for

liquid, wide tube for gas.

When servicing

• Turn the power OFF at the main power board before opening

the unit to check or repair electrical parts and wiring.

• Keep your fingers and clothing away from any moving parts.

• Clean up the site after the work, remembering to check that no

metal scraps or bits of wiring have been left inside the unit being

serviced.

• Ventilate the room during the installation or testng the refrigeration

system; make sure that, after the installation, no gas leaks are

present, because this could produce toxic gas and dangerous

if in contact with flames or heat-sources.

5.FUNCTION

5-1 System operation control

The inputs to the systems come from indoor and outdoor sensors. The outdoor unit is the system

MASTER while the indoor one is the SLAVE.

Communication between units is made with a 2 poles RS485 bus

The indoor units receives the user input (fan speed, flap position etc) through remote controlle

which sends signal every time a button is pressed and in any case, automatically, every 5 minutes

5.1.1 control specification

During operation compressor speed can be subjected to change due to thermal load variations

or protection activations but in any case:

• The minimum time interval between an OFF and a ON operation is not lower than 3 minutes

• The minimum operating time is not lower than 3 minutes

• The maximum acceleration/deceleration rate is fixed at 20rpm /sec

• During the start-up compressor speed increases according to a defined rule which is

independent from the thermal load calculation.

5-1.2 Multisplit available modes

If the unit is a part of a multisplit system, there could be some mode combination not available

(example: unit A - heat mode and unit B - cool mode).

In this case the system automatically stops, leds TMR and STB blink while led OPR is on

●= LED blinking

●= LED on
