Domestic water safety
In accordance with safety rules, a safety valve calibrated to 0.7 MPa (7
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.
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 the installation
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
consent 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.
