exchanger inside the heat pump will be damaged.

2. Installation and maintenance

The heat pump must be installed by a professional team. The users are not qualified to

install by themselves, otherwise the heat pump might be damaged and risky for users’

safety.

2.1. Notice before installation：

2.1.1. The inlet and outlet water unions can’t bear the weight of soft pipes. The heat pump

must be connected with hard pipes!

2.1.2．In order to guarantee the heating efficiency, the water pipe length should be ≤10m

between the pool and the heat pump.
