In order to limit the risk of being scalded, a thermostatic mixing valve must
be installed on the domestic hot water flow pipes.
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.
Keep a heating circuit without thermostatic valve and or without solenoid
valve in order to avoid having all valves closed at the same time.
Fit drainage valves between the indoor module and the heating circuit.
Do not add any chemical products to the heating water without first con­
sulting a water treatment specialist. For example: antifreeze, water soften­
ers, 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.
Install the heat pump's indoor module in a frost-free location.
Insulate the pipes to reduce heat losses to a minimum.
Apply refrigerant oil to the beaded parts to facilitate tightening and improve
the seal.
Keep this document close to the place where the appliance is installed.
Do not make any modifications to the heat pump without the written con­
sent of the manufacturer.
To benefit from extended warranty cover, no modifications should be
made to the appliance.
Install the heat pump indoor module and outdoor unit on a solid, stable
structure able to bear its weight.
Do not install the heat pump in a place that has an atmosphere with a high
salt content.
Do not install the heat pump in a place exposed to steam and combustion
gases.
Do not install the heat pump in a place that may be covered in snow.
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 in­
door unit and the hydraulic or electrical back-up if connected.
Wait for approx. 20-30 seconds for the outdoor unit capacitors to be dis­
charged, 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 pres­
sures, which may cause serious injuries.
Locate and correct the cause of power cut before resetting the safety ther­
mostat.
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.
Do not allow the refrigerant fluid to escape into the atmosphere.
