1.3 Installation and Connection - Split Unit
1. Connection3.1 of the two units of the SPLIT Heat Pump
Description and Location
The Main Unit (the bigger cabinet) has to be located outside (under special conditions
also inside - in a room with warm air continuously regenerated with energy, eg. with
equipment that continuously warm the air).
The Heat Exchanger (the smaller cabinet) is supposed to be installed in the filter room
connected to the water flow from the filter. On the Heat Exchanger there is
display/control panel.
The distance between these units should be kept within 10 m (33 ft). The Main Unit must
be connected to the Heat Exchanger with 2 pipes for the refrigerant (see the picture
below). One pipe is bigger than the other. The bigger (thicker) pipe is transporting
the refrigerant gas from the Main Unit to the Heat Exchanger (inside). In the Heat
Exchanger the energy is transferred to the pool water, the gas turns into liquid form
and is transported by the smaller pipe back to the Main Unit. (The liquid needs
smaller pipe than the gas.)
