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.
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.
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 hydraulic or 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.
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.
