IMPORTANT MAINTENANCE INFORMATION
The fancoil is connected to the power supply 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 surrounding 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. incubation).
AIR THE ROOM
Periodically air the room in which the fancoil has been installed; this is particularly important if the room is occupied 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 fluctuations between indoors and outdoors greater than 7 °C during sum-
mer.
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 tempera-
ture, 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).
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 (otherwise 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.
During heating operation a light rustling sound may be perceived near the fancoil.
Sometimes the fancoil can give off unpleasant odours due to the accumulation of substances present in the room: air the
room and clean the filter more often.
OPERATING LIMITS
Maximum water inlet temperature
80 °C
Maximum working pressure
8 bar
Minimum average water temperature
To prevent the formation of condensation on the exterior of the unit while the fan is operating, the average water temperatu-
re 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 circu-
lates through the coil while the fan is off for prolonged periods of time, so it is advisable to fit the additional three-way
valve.
