GENERAL INSTRUCTIONS (continued)
Safety instructions
This device contains R32.
Never use a refrigerant other than R32. Any other gas mixed with
R32 could cause abnormally high pressure and lead to a failure
or pipes bursting and injuring people.
When doing repairs or maintenance, use copper tubing in
compliance with standard EN 12375-1 (May 2020) and with
European Directive 97/23/EC on Pressure Equipment.
As the heat pump is pressurised, never pierce the pipes or
attempt any brazing, as there is a risk of explosion.
Never expose the device to flames, sparks, or other sources of
ignition. The gas could explode and cause serious or even fatal
injuries.
The heat pump is intended exclusively for installation outside of
buildings.
• If kept in storage, the heat pump should be kept in a well-ventilated room with
a floor area larger than the minimum area (Amin in m²), as calculated by the
following formula: Amin = (M/(2.5 x 0.22759 x h0))².
M is the amount in kg of refrigerant in the device, and h0 is the storage height.
If stored on the floor, h0 = 0.6 m.
• If you detect a fault or any abnormal situation, do not install the heat pump and
contact your dealer immediately.
• Upkeep and maintenance should be performed at the recommended frequency
and times, as specified in this manual.
• Repairs must be carried out by qualified personnel, and only with original
equipment manufacturer (OEM) parts.
• Never use a cleaning method other than the one recommended in this manual.
