    • Place the heat pump in a suitable location outdoors to prevent any risk of the refrigerant flowing in through Do not place S2125 directly on the lawn or other non ventilation openings, doors or similar openings in the solid surface.
  • Page 10 If S2125 needs to be transported across soft ground, such as a lawn, we recommend using a crane truck that can lift it to the installation location. When S2125 is lifted with a crane, the packaging must be untouched. If a crane vehicle cannot be used the S2125 can be transported on an extended sack truck.
