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 unit and the heating circuit.
Fit drainage valves between the indoor unit 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 the installation
Install the heat pump's indoor unit in a frost-free location.
Insulate the pipes to reduce heat losses to a minimum.
Apply refrigerant oil to the flared 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
consent of the manufacturer.
To benefit from extended warranty cover, no modifications should be
made to the appliance.
Install the heat pump indoor unit 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.
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 power supply to the heat pump, the indoor
unit and the electrical back-up.
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.
