Safety instructions

This device contains R32.
Never use a refrigerant other than R32. Any other gaseous body
mixed with R32 could cause abnormally high pressure and lead
to a failure or pipes bursting and injuring people.
When carrying out repairs or maintenance work, never use
copper tubes less than 0.8 mm thick.
As the heat pump is pressurized, never pierce the pipes or
attempt any brazing. There is a risk of explosion.
Never expose the device to flames, sparks or other sources of
ignition. It could explode and cause serious or even fatal injuries.
• If kept in storage, the heat pump should be kept in a well-ventilated room with
a floor area of more than A
A = (M/(2.5 x 0.22759 x h0))².
min
M is the quantity of refrigerant in the device in kg, and h0 is the storage height.
If stored no the floor, h0 = 0.6 m.
• The heat pump is designed exclusively for installation outside buildings.
