What does the Nautilus500’s external unit look like?

The external unit combines a 350lph pump, a radiator and a 120mm fan (12V, 0.3A, 1800rpm, 74.4CFM). There are no controls on the front panel, just the name of the system and a narrow slit which is highlighted at work. It is also an indicator of the On/Off status and of the level of liquid in the system.

On the top panel there is an opening for pouring liquid in and a 120mm fan under a protective grid. On the bottom panel there is a radiator and feet with soft stickers so that they didn’t scratch the surface of the system case or desk. The fan is blowing air through the radiator from bottom to top.

At the back of the unit there is a fan speed selector (it can be set at High or Low positions), a connector for power and for pump and fan speed control, and two fittings for pipes. The fittings have valves that do not allow the liquid to flow out of the system when you disassemble it.
