3.3 The flow bar

The flow bar is a graphical representation of the water volume through the unit. The heat pumps has
it best performance when the flow bar is in the green zone. The graph is only valid after at least 30
minutes of operation. The flow bar also represents the three-minute time delay before the actual start
of the unit. The indication "flow" is not visible; the small block at the very right end of the flow bar is
flickering and disappears after a while. When they are all gone, the unit will start.

4. Maintenance and inspection

4.1 Maintenance

• Check the water supply to the unit often. Low water flow and air entering into the system
should be avoided, as this will diminish the units' performance and reliability. You should
clean the pool/spa filter regularly to avoid damage to the unit as a result of the dirty or
clogged filter.
• The area around the unit should be dry, clean and well ventilated. Clean the side
heating exchanger regularly to maintain good heat exchange and to save energy.
• Check the power supply and cable connection often. Should the unit begin to operate
abnormally or do you smell something unusual around the electrical compartment,
switch off the heat pump and have it replaced on a timely manner.
