4.1.2 Charge pumps
The CTC EcoPart XL is available in three different versions:
• CTC EcoPart XL
Standard brine pumps
No charge pumps
• CTC EcoPart XL LEP (low energy pump)
Low energy brine pumps
No factory-fitted charge pumps
• CTC EcoPart XL 4xLEP (low energy pump)
Low energy brine pumps
Low energy charge pumps
The selection of charge pump depends on the type of system. To ensure proper
operation, the flows in the heating medium circuit should not be lower than the
values in the table under Technical data. Ensure that the circulating pump fitted
is large enough, so that there is sufficient flow through the heat pump. If the flow
is too low, there is a risk that the high pressure switch will be triggered.
The charge pump can be connected either to the CTC EcoPart XL (provided it
is installed internally) or to the product used to control it. For internal installation
one of the following is normally selected:
