Duratech ECO+ Series - Electrical Connection

7/14
ECO+ series swimming pool heat pumps
3.6 Electrical connection
Important – Although the heat pump is electrically isolated from the swimming pool installation,
this only prohibits electrical current to or from the swimming pool water. Grounding the heat
pump is required to protect you against electrical shock caused by an eventual short circuit
inside the unit. Make sure you have a solid grounding.
Always check if the voltage from the network corresponds with the operating voltage of the unit.
The heat pump must only operate together with the filter pump. Both should always be powered
together. Therefore, connect them to the same circuit breaker. The heat pump will get damaged
when operated without water flow and will void warranty.
Please adhere to the following guidelines for the rest of the electrical installation:
