Description
What the bypass is for
This three-way bypass by Mountfield (code 3EXX0470) is installed in the water circuit leading to the heat pump. It lets you set how much water passes through the pump so that the unit runs at its best efficiency, and you can take it out of the circuit entirely without stopping the pool filtration.
Advantages
- Adjusts the speed of the water through the heat pump.
- Can stop the water from passing through the unit – the filtered water then returns straight to the pool.
- Allows servicing of the heat pump without draining the pool.
- A useful addition to any new heat pump installation.
