▶
Ensure that the required minimum clearances can be
maintained.
▶
When selecting the installation site, you must take into
consideration that when the heat pump is in operation, it
will transfer vibrations to the floor and any nearby walls.
▶
Ensure that the floor is level and has sufficient load-bear-
ing capacity to bear the weight of the heat pump and a
domestic hot water cylinder.
▶
Ensure that cables can be easily routed (for brine, do-
mestic hot water and heating).
