IMPORTANT MAINTENANCE INFORMATION

WARNING: the filter may only be removed from the sea-

led box and fitted to the unit at the time it will be used for

the first time. The electrostatic charge when functioning

normally runs out after around two years from the opening

of the sealed box. After this date the filter maintains its

mechanical function. You are advised to substitute a new

electrostatically pre-charged filter that you can find at our

assistance centres.

WARNING: The fancoil is connected to the power sup-

ply and a water circuit. Operations performed by persons

without the required technical skills can lead to personal

injury to the operator or damage to the unit and surround-

ing objects.

POWER THE FANCOIL WITH SINGLE-PHASE 230 V ONLY

Use of other power supplies could cause permanent damage

to the fancoil.

NEVER USE THE FANCOIL FOR APPLICATIONS FOR

WHICH IT WAS NOT DESIGNED

Do not use the fancoil in husbandry applications (e.g. incu-

bation).

AIR THE ROOM

Periodically air the room in which the fancoil has been

installed; this is particularly important if the room is occu-

pied by many people, or if gas appliances or sources of

odours are present.

CORRECTLY ADJUST THE TEMPERATURE

Room temperature should be regulated to ensure maximum

comfort to persons present, particularly in the case of the

elderly, infants and invalids. Prevent temperature fluctua-

tions between indoors and outdoors greater than 7 °C during

summer.

Note that very low temperatures during summer will lead to

greater electricity consumption.

ORIENT AIR FLOW CORRECTLY

Air delivered by the fancoil should not be oriented directly

at people; even if air temperature is greater than room tem-

perature, it can cause a cold sensation and consequently

discomfort.

DO NOT USE HOT WATER

When cleaning the indoor unit, use rags or soft sponges

soaked in warm water (no higher than 40°C).

OPERATING LIMITS

Maximum water inlet temperature 80 °C

Maximum working pressure

The assembly site must be chosen in such a way that the

maximum and minimum ambient temperature limits are

respected 0÷45°C (<85% U.R.).

Minimum average water temperature

To prevent the formation of condensation on the exte-

rior of the unit while the fan is operating, the average water

MINIMUM AVERAGE WATER TEMPERATURE

Wet bulb temperature °C

Do not use chemical products or solvents to clean any part

of the fancoil.

Do not splash water on interior or exterior surfaces of the

fancoil; danger of short circuit.

PERIODICALLY CLEAN THE FILTER

Frequent cleaning of the filter will ensure more efficient unit

operation.

Check whether the filter requires cleaning; if it is particularly

dirty, clean it more often.

Clean the filter frequently. Use a vacuum cleaner to remove

built up dust. Avoid water or detergents if possible since

they greatly accelerate loss of the filter's electrostatic charge.

After cleaning and drying the filter, fit it on the fancoil by

following the removal procedure in reverse order.

SPECIAL CLEANING

The removable drip tray and fan volute ensure thorough

cleaning of the unit (by specifically trained personnel),

essential for installations in venues subject to crowding or in

those with special hygiene requirements.

DURING UNIT OPERATION

Always leave the filter on the fancoil during operation (oth-

erwise dust in the air could soil the surface of the coil).

IT IS NORMAL

During cooling, water vapour may be present in the air

delivery of the fan coil.

In the heating function it might be possible to hear a slight

hiss around the fan coil. Sometimes the fan coil might give

off unpleasant smells due to the accumulation of dirt in the

air of the environment (especially if the room is not venti-

lated regularly, clean the filter more often).

During the operation, there could be noises and creaks

inside the device, due to the various heat expansions of the

elements (plastic and metallic), but this does not indicate

any malfunctioning and does not cause damage to the unit

unless the maximum input water temperature is exceeded.

WARNING

Avoid that the device is used by children or incompetent

8 bar

temperature should not drop beneath the limits shown in

the table below, determined by the ambient conditions.

These limits refer to unit operation with fan at minimum

speed. Note that condensation may form on the exterior of

the unit if cold water circulates through the coil while the

fan is off for prolonged periods of time, so it is advisable to

fit the additional three-way valve.

unit should not be used by children as a game.
