● The heat pump must be properly protected from the rain and direct sunlight.
● The machine room needs to be properly lit and ventilated. Escape and access
routes must be unobstructed and the site must have working emergency lighting.
● The maximum altitude for the installation site is 5,000 m.
Refrigerant circuit site requirements
Refrigerant circuits are equipped with pressure relief valves. In fault situations they will
discharge any excess pressure in the circuits.
Refrigerant circuit safety valves
Not present in model P 30
It is recommended to draw the safety valves' blow-off pipes to outside the building
in a location where a refrigerant discharge does not pose a risk. Also check the
requirements of local standards, laws, and other regulations concerning blow-off pipe
locations.
The blow-off pipe must be approximately 5 meters long (measured from the valve's
blow-off port). If the pipe length exceeds 5 meters, calculate the diameter of the blow-
off pipe according to standard EN 13136.
Space requirements
For installation, operating and maintenance purposes, leave enough space on each
side of the heat pump. The minimum space requirements are listed in the following.
By default, the control cabinet is attached to the right side of the heat pump. On
request, the control cabinet can be moved to the left side of the heat pump.

Make sure that potential pressurized discharge from refrigerant circuit's
pressure relief valves does not cause danger to people or property.
