bar) is mounted on the tank's domestic cold water inlet.
A pressure reducer (not provided) is required when the supply pressure
exceeds 80% of the safety valve or safety unit calibration and must be
located upstream of the appliance.
There must be no cut-off devices between the safety valve or unit and the
domestic hot water tank.
The hydraulic installation must be capable of handling a minimum flow rate
at all times.
1 Safety instructions and recommendations
7701562 - v02 - 22052018 iHPI 5

Heating water and domestic water must not come into contact with each
other. Domestic water must not circulate through the exchanger.
Limit temperature at the draw-off point: the maximum domestic hot water
temperature at the draw-off point is subject to special regulations in the
various countries in which the appliance is sold in order to protect the
user. These special regulations be observed when installing the appliance.
Take precautions with the domestic hot water. Depending on the heat
pump settings, the domestic hot water temperature may exceed 65°C.
In order to limit the risk of being scalded, a thermostatic mixing valve must
be installed on the domestic hot water flow pipes.
1.6 Hydraulic safety
When making the hydraulic connection, it is imperative that the standards
and corresponding local directives be respected.
If radiators are connected directly to the heating circuit: install a differential
valve between the indoor module and the heating circuit.
Fit drainage valves between the indoor module and the heating circuit.
Do not add any chemical products to the heating water without first
consulting a water treatment specialist. For example: antifreeze, water
softeners, products to increase or reduce the pH value, chemical additives
and/or inhibitors. These may cause faults in the heat pump and damage
the heat exchanger.
1.7 Recommendations for operation
The frost protection function does not work if the heat pump is switched
off.
If the home is unoccupied for a long period and there is a risk of frost,
drain the indoor module and the heating system.
Keep the heat pump accessible at all times.
Never remove or cover the labels and data plates affixed to appliances.
Labels and data plates must be legible throughout the entire lifetime of the
appliance.
Immediately replace damaged or illegible instructions and warning
stickers.
Give preference to the OFF or frost protection mode rather than switching
off the system to leave the following functions running:
Anti blocking of pumps
Frost Protection
Regularly check the presence of water and pressure in the heating
system.
Do not touch radiators for long periods. Depending on the heat pump
settings, the temperature of the radiators may exceed 60°C.
Do not drain the installation, except in cases of absolute necessity. E.g.:
several months' absence with the risk of temperatures in the building
falling below freezing.
1.8 Specific instructions for service, maintenance and breakdowns
Maintenance work must be carried out by a qualified professional.
Only a qualified professional is authorised to set, correct or replace the
safety devices.
Before any work, switch off the mains electricity to the heat pump, the
indoor unit and the electrical back-up if present.
Wait for approx. 20-30 seconds for the outdoor unit capacitors to be
discharged, and check that the lights on the outdoor unit PCBs have gone
out.
1 Safety instructions and recommendations
6 iHPI 7701562 - v02 - 22052018

Before working on the refrigeration circuit, switch off the appliance and
wait a few minutes. Certain items of equipment such as the compressor
and the pipes can reach temperatures in excess of 100 °C and high
pressures, which may cause serious injuries.
Locate and correct the cause of power cut before resetting the safety
thermostat.
Only genuine spare parts may be used.
Removal and disposal of the heat pump must be carried out by a qualified
professional in accordance with prevailing local and national regulations.
After maintenance or repair work, check the entire heating system to
ensure that there are no leaks.
Remove the casing only to perform maintenance and repair work. Put the
casing back in place after maintenance and repair work.
The user must make sure the refrigerant pipes are checked annually for
leaks for any heat pump with a charge greater than 5 tonnes of CO2
equivalent.
