1 Safety
1.1 General safety instructions
Danger
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.
Caution
In the event of a refrigerant leakage:
1. Switch off the appliance.
2. Open the windows.
3. Do not use a naked flame, do not smoke, do
not operate electrical contacts or switches
(doorbell, light, motor, lift, etc.).
4. Avoid contact with the refrigerant. Danger of
frost injuries.
5. Locate the probable leak and seal it
immediately.
Danger of electric shock
Before any work, switch off the mains supply to
the thermodynamic water heater.
Important
Only qualified professionals are permitted to
install the thermodynamic water heater, in
accordance with prevailing local and national
regulations.
Warning
Do not touch the refrigeration connection pipes
with your bare hands while the heat pump is
running. Danger of burn or frost injury.
Caution
Take precautions with the domestic hot water.
Depending on the settings of the thermodynamic
water heater, the domestic hot water temperature
may exceed 65°C.
Caution
Only genuine spare parts may be used.
1 Safety
7740321 - v04 - 03122019 SPC Split 5

Important
Only qualified professionals are authorised to
assemble, connect, commission and service the
installation.
1.2 Recommendations
Important
The thermodynamic water heater is intended to
be permanently connected to the domestic water
mains network.
Important
Respect the minimum and maximum water inlet
pressure to ensure correct operation of the
domestic hot water tank: refer to the chapter
Technical Specifications.
Caution
The pressure limiter device must be regularly
operated in order to remove limescale deposits
and ensure that it is not blocked.
A pressure reducer (not provided) is necessary
when the supply pressure exceeds 80% of the
calibration of the safety valve or safety unit and
it must be located upstream of the appliance.
As water may flow out of the discharge pipe on
the pressure limiter device, this latter must be
kept clear and open to the air.
Connect the pressure limiter device to a drain
pipe, kept open to the air, in a frost-free
environment, and at a continuous downward
gradient.
Caution
Draining the domestic hot water tank:
1. Shut off the domestic cold water inlet.
2. Open a hot water tap in the installation.
3. Open a valve on the safety unit.
4. When the water stops flowing, the domestic
hot water tank has been drained.
Caution
Install the thermodynamic water heater in a frost-
free environment.
1 Safety
6 SPC Split 7740321 - v04 - 03122019

Caution
Do not neglect to service the thermodynamic
water heater. Contact a qualified professional or
take out a maintenance contract for the obligatory
annual servicing of the thermodynamic water
heater.
Failure to service the appliance voids the
warranty.
Caution
Drain the domestic hot water tank and heating
system if the home is left empty for a long period
of time and there is a chance of frost.
Important
Keep the domestic hot water tank and the
outdoor unit accessible at all times.
Important
Never remove or cover labels and data plates
affixed to the thermodynamic water heater.
Labels and data plates must be legible
throughout the entire lifetime of the
thermodynamic water heater. Immediately
replace damaged or illegible instructions and
warning labels.
Caution
Remove the thermodynamic water heater casing
only to perform maintenance and repair work.
Always put the casing back in place after such
work.
Important
Keep this document close to the place where the
appliance is installed.
Caution
To benefit from extended warranty cover, no
modifications should be made to the appliance.
Warning
In accordance with the NFC 15-100 electrical
safety standard, only qualified professionals are
permitted access to the inside of the appliance.
1 Safety
7740321 - v04 - 03122019 SPC Split 7

Caution
The electric part of the domestic hot water tank
must always be connected to the protective
earthing.
Earthing must comply with the prevailing
installation standards.
Earth the appliance before making any electrical
connections.
For the type and calibre of the protective
equipment, refer to the chapter Electrical
Connections in the Installation and Service
Manual.
Caution
Install the outdoor unit on a solid, stable structure
capable of bearing its weight.
Caution
Do not install the thermodynamic water heater in
a place that has an atmosphere with a high salt
content.
Caution
Do not install the thermodynamic water heater in
a place exposed to steam or combustion gases.
Warning
Do not bring the heating water and the domestic
water into contact with each other in the the
heating system.

1.3 Specific safety instructions
Warning
Refrigerant fluid and pipes:
Only use R-134a refrigerant fluid to fill the
system.
Use tools and pipe components especially
designed for use with R-134a refrigerant fluid.
Use copper pipes deoxidised with phosphorus
to carry the refrigerant fluid.
Use beading to guarantee the tightness of the
connections.
Store the refrigerant connection pipes away
from dust and humidity (risk of damage to the
compressor).
Cover both ends of the pipes until the beading
process.
Do not use a load cylinder.
Regarding information on installation on the
appliance, electrical connection and connection
of the water circuit, refer to the paragraphs
below in this manual.
Regarding information on handling, servicing
and scrapping the appliance, refer to the
paragraphs below in this manual.
Caution
