Installation, use and maintenance manual SITALI SF 150 S1
Read this manual carefully before using the product and keep it in a safe place for reference.
This product was constructed up to standard and in compliance with regulations relating to electrical equipment and must be installed by
technically qualified personnel.
The manufacturer assumes no responsibility for damage to persons or property resulting from failure to observe the regulations contained
in this booklet.
PRECAUTIONS FOR INSTALLATION, USE AND MAINTENANCE
• The device should not be used for applications other than those specified in this manual.
• After removing the product from its packaging, verify its condition. In case of doubt, contact a qualified technician. Do not leave
packaging within the reach of small children or people with disabilities.
• Do not touch the appliance with wet or damp hands/feet.
• This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities
or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way
and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by
children without supervision.
• Do not use the product in the presence of inflammable vapours, such as alcohol, insecticides, gasoline, etc.
• If any abnormalities in operation are detected, disconnect the device from the mains supply and contact a qualified technician
immediately. Use original spare parts only for repairs.
• The electrical system to which the device is connected must comply with regulations.
• Before connecting the product to the power supply or the power outlet, ensure that:
- the data plate (voltage and frequency) correspond to those of the electrical mains
- the electrical power supply/socket is adequate for maximum device power. If not, contact a qualified technician.
• The device should not be used as an activator for water heaters, stoves, etc., nor should it discharge into hot air/fume vent ducts
deriving from any type of combustion unit. It must expel air outside via its own special duct.
• Operating temperature: -20°C up to +50°C.
• The device is designed to extract clean air only, i.e. without grease, soot, chemical or corrosive agents, or flammable or explosive
mixtures.
• Do not leave the device exposed to atmospheric agents (rain, sun, snow, etc.).
• Do not immerse the device or its parts in water or other liquids.
• Turn off the main switch whenever a malfunction is detected or when cleaning.
• For installation an omnipolar switch should be incorporated in the fixed wiring, in accordance with the wiring regulations, to provide a full
disconnection under overvoltage category III conditions (contact opening distance equal to or greater than 3mm).
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a
hazard.
• Do not obstruct the fan or exhaust grille to ensure optimum air passage.
• Ensure adequate air return/discharge into/from the room in compliance with existing regulations in order to ensure proper device
operation.
• If the environment in which the product is installed also houses a fuel-operating device (water heater, methane stove etc., that is not a
"sealed chamber" type), it is essential to ensure adequate air intake, to ensure good combustion and proper equipment operation.
• Install the product so that the impeller is not accessible from the air outlet side as verified by contact with the Test Finger (test probe "B"
of the norm EN61032) in compliance with the current safety regulations.
INTRODUCTION
SITALI SF 150 S1 is a single alternate flow decentralized (single point) residential heat recovery unit, also called «push&pull» unit, designed
to ensure adequate ventilation in enclosed environments without energy losses.
It is recommended that two units are installed in a pair: when one unit is pulling, the other is pushing.
The pair of units can be installed in the same room or in different rooms (i.e. living-room and bedroom). The unit is suitable for installation
on an outside wall.
When heat exchange is not useful (for example in mid-seasons when indoor and outdoor temperatures are similar), or when heat
exchange is not recommended (for example with the option "summer free cooling"), it is recommended to set the unit in "extract-only"
TECHNICAL SPECIFICATIONS
• Design front cover (A) removable for cleaning without the use of tools.
• Inner ventilation unit (B) and wall support base (D) made of high quality, impact and UV-resistant ABS, colour RAL 9010.
• Integrated multi-colour led (C ) to obtain a visual feedback of the unit status.
• Smart humidity control.
• Integral temperature sensor for the automatic management of the inversion time (comfort mode).
• Automatic anti-frost protection to prevent frost building up on the heat exchanger.
• Wall support base (D) provided with a magnet "coupling/uncoupling" system which allows the ventilation unit to be removed from its
base during maintenance.
• Back-up touch button (E) at the side of the ventilation unit.
• Unique design winglet-type impeller, providing enhanced aerodynamic properties, low noise and increased efficiency.
• High efficient reversible EC motor with integral thermal protection, mounted on sealed for life high quality ball bearings. Designed for
continuous reversible running.
• Telescopic pipe (F) adaptable to the wall thickness.
• Antimortar cap designed to be used also as template during the installation of the wall support base.
• Regenerative heat exchanger with ceramic core (G) with high thermal efficiency, equipped with washable anti-dust filters (H).
