Transportation

• When storing or moving the heat pump, the heat pump should be at the upright
• When moving the heat pump, do not lift the water union since the titanium heat exchanger inside the heat pump will be damaged.

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.

Notice before installation

• The inlet and outlet water unions can’t bear the weight of soft pipes. The heat pump must be connected with hard pipes!
• In order to guarantee heating efficiency, the water pipe length should be ≤10m between the pool and the heat pump.

Installation instruction

Location and size

• The heat pump should be installed in a place with good ventilation
