1. GENERAL SAFETY PRECAUTIONS
CAUTION:
• This manual is an integral part of the product. Keep it with care with the appliance,
and hand it on to the next user/owner in case of change of property.
• These instructions are also available from the manufacturer’s customer service and
its website.
• Read the instructions and warnings in this manual carefully, they contain important
information regarding safe installation, use and maintenance.
SAFETY WARNINGS
Do not use the appliance for any other than its specied use. The manufacturer is not liable for damage
resulting from improper or incorrect use or failure to observe the instructions given in this manual.
This appliance is not intended for use by persons (including children) whose physical, sensory or
mental capacities are reduced, or persons without experience or knowledge, unless they have been
given instructions and monitored previously when using the appliance by a person responsible for
their safety.
Children must be supervised to ensure they do not play with the appliance.
This appliance may be used by children 8 years of age or older, and those with reduced physical,
sensory or mental capacity or lack of experience or knowledge, if they are properly supervised or
if instructions for the safe use of the appliance have been given to them and the risks involved are
clear to them.
Children are not permitted to play with the appliance.
Water heated to over 50°C can cause immediate serious burns if delivered directly to the taps.
Children, disabled persons and the elderly are particularly at risk. It is recommended to install
a thermostatic mixer valve on the water delivery line.
This appliance must not be cleaned or maintained by children without supervision.
Do not touch the appliance when barefoot or if any part of your body is wet.
Do not leave ammable materials in contact with or in the vicinity of the appliance.
The appliance must be emptied when it is out of service in an area subject to subzero
temperatures. Drain as described in the appropriate chapter.
INSTALLATION CAUTION
The appliance must be installed and commissioned by a qualied technician in accordance with
local legislation and health and safety regulations. All power circuits must be shut o before you
open the terminal block.
Page 3User, Installations and Maintenance Manual
Incorrect installation can result in damage to property and injury to persons and animals; the
manufacturer is not liable for the consequences.
This product is heavy, handle with care and install the product in a frost-free room.
Ensure that the bulkhead can support the weight of the water lled appliance.
The destruction of the appliance by overpressure due to the blocking of the safety device
inactivates the warranty.
INSTALLATION WARNINGS
When installing this product in a bathroom do not use the “Prohibited space” and respect, at least,
the “Protected space” listed as shown below:
Prohibited space Protected space
This product must be placed in an accessible location.
The water heater must be xed to the ground using the xing bracket provided for this purpose and
adhesives are not considered to be a reliable xing means.
This product is designed to be used at a maximum altitude of 2000 m.
Refer to description and illustrations in paragraphs 6.1, 6.2 and 6.4.
AERAULIC CONNECTIONS WARNINGS
The simultaneous operation of an open-chamber hearth (e.g. open replace) and the heat pump
causes a dangerous negative pressure in the room. The negative pressure can cause the return of
exhaust gases into the room. Do not operate the heat pump together with an open-chamber hearth.
Only use sealed-chamber hearths (approved) with separate combustion air supply.
Seal the doors of boiler rooms that do not have the inow of combustion air in common with living
areas.
A suitable protection grille must be installed both at the air intake and outtake connections to
prevent any foreign bodies from going inside the equipment.
Refer to description and illustrations in the “Aeraulic connections.” paragraph 6.3.
Page 4 User, Installations and Maintenance Manual
HYDRAULIC CONNECTIONS WARNINGS
It is mandatory to screw on to the appliance’s water intake pipe a suitable device against
overpressure (not supplied). In countries which acknowledge EN 1487, the appliance’s water intake
pipe must be equipped with a safety device compliant with previously mentioned standard.
It must be new, with 3/4” dimensions and calibrated to a maximum pressure of 0.7 MPa, including
at least a cock, check valve, safety valve and hydraulic load cut-out.
This safety device must not be tampered with and must be made to operate frequently in order to
check that it is not blocked and to remove any limescale.
The water may drip from the discharge pipe of the pressure-relief device and the pipe must be
left open to the atmosphere. The discharge pipe connected to the pressure-relief device is to be
installed in a continuously downward direction and in a frost-free environment.
A pressure reducer (not supplied) is required when the inlet water pressure is greater than 0.5 MPa
(5 bar), which must be attached to the water mains.
The minimum inlet water pressure for the correct operation of the appliance is 0.15 MPa (1.5 bar).
For models that incorporate a heat exchanger (solar coil), the circuit must not exceed 1.0 MPa (10
bar) and its temperature must not exceed 80°C.
Refer to description and illustrations in the “Hydraulic connections” paragraph 6.5 and “Integration
with solar thermal system” paragraph 6.6.
ELECTRICAL CONNECTIONS WARNINGS
The appliance shall be installed in accordance with national wiring regulations.
The electrical installation must include an all-pole disconnection device (circuit-breaker, fuse)
upstream of the appliance, complying with local installation rules in force (30 mA dierential circuit
breaker).
Earth connection is mandatory. The manufacturer of the appliance shall not be held liable for any
damage caused by failure to earth the system or due to anomalies in the electric power supply.
It is strictly forbidden to connect the appliance at the AC mains through extensions or by a power strip.
Before taking o the cover, make sure that the power is turned o to prevent injury or electric shock.
Refer to description and illustrations, respectively, in the “Electrical connections” paragraph 6.7 and
“Wiring diagram“ paragraph 6.8.

SERVICING - MAINTENANCE - TROUBLESHOOTING WARNINGS
Any repairs, maintenance, plumbing and electrical connections must be done by qualied
technicians using original spare parts only. Failure to observe the above instructions can
compromise the safety of the appliance and relieves the manufacturer of any liability for the
consequences.
To empty the appliance: turn o the power supply and cold water, open the hot water taps and then
operate the drain valve of the safety device.
The pressure relief valve must be operated regularly to remove scale deposits and to ensure that
it is not blocked.
The appliance is equipped with a supply cord that if damaged, must be replaced by the
manufacturer, its service agent or similarly qualied persons in order to avoid a hazard.
The appliance incorporates a time-Iag miniature fuse-link that if broken, it must be replaced with
a fuse model “T5AL250V” in accordance with IEC 60127.
Refer to description and illustrations, respectively, in the “TROUBLESHOOTING” chapter 9 and
“MAINTENANCE” chapter 10.
