Frequently Asked Questions about the AstralPool Marlin II (FAQ)

What exactly is included in the AstralPool Marlin II kit?

The convenience of a complete modular system

The affordable AstralPool Marlin II kit is designed to include everything required for a basic installation in the pool wall. The set precisely comprises the faceplate assembly, plastic housing box, electric control panel, and the 3 HP (2.2 kW) jet pump. This prevents compatibility errors between parts and reduces assembly time.

What is the difference between the Marlin 30 and Marlin 45 models?

Choose the ideal flow rate for your swimming profile

The model numbering (Marlin 30 and Marlin 45) is associated with the performance and hydraulic flow rate designed for the system. The Marlin 30 model is perfect for recreational swimming, moderate-paced training, and family hydrotherapy, while the Marlin 45 III offers a substantially stronger water current, making it the most suitable choice for experienced swimmers or those requiring higher physical resistance.

Can this counter-current system be installed in any type of pool?

Structural compatibility and construction planning

The Marlin counter-current equipment adapts to most residential pools. However, due to the need to embed the plastic housing box into the structural wall, its installation is ideally planned during the pool’s construction phase or during a major renovation. Specific faceplate kits are available depending on whether the pool is made of concrete, liner, or fiberglass.

What is the purpose of the control panel included in the kit?

Electrical safety and equipment control

The control panel is a mandatory safety component that protects the pump motor against electrical overloads or short circuits. It manages the electrical supply to the 230V pump and allows the user to turn the counter-current flow on or off safely using the pneumatic or piezoelectric button located right on the pool faceplate.
