Rainman Control Panel
Whether it’s a traditional Rainman in a blue case or the newer modular configuration, over half of our customers install their watermaker. The Rainman control panel is an optional accessory designed to provide a highly presentable and functional interface. If you prefer a minimalist control setup, the control panel is not required.
The control panel retains the Rainman simplicity for which we are known, while incrementally adding a number of convenient features to allow for simpler access and remote control.
Installing the Rainman control panel will not only create a neat and tidy remote management of your watermaker, but it provides a number of feature enhancements to the normal user experience.

BACKWARDS COMPATIBILITY
Do you have an existing Rainman and wish to add a Control Panel? This is easily done, but you may need to update a few components to ensure compatibility. Please contact us to find out exactly what is required to make your system compatible with our Control Panel.
Three installation options
Installing the Rainman control panel will not only create a neat and tidy remote management of your watermaker, but it provides a number of feature enhancements to the normal user experience.

Flush Mount
Cut a space out on a surface for a flush mounted control panel. All plumbing and wiring will be behind the panel, making for a very neat installation.

Standalone Enclosure Box
If you do not have available space for a cutout, the panel comes with an enclosure box that can be easily screwed or glued on the bottom, either side, or rear. This provides maximum flexibility on the installation location.

External Hatch
If you wish to mount your control panel externally, we offer an optional hatch adapted for your control panel to be flush mounted.
Simple installation
Autoflush integration
If you have the optional Rainman autoflush system, the power switch will not only turn the pressure supply unit (PSU) on and off, but has a third position that will trigger a flush cycle and reset the flush timer to a seven day countdown.
The flush timer box is unpowered when the watermaker is operating, which ensures a flush cycle will not accidentally be initiated.
An extension of the blue LED timer indicator is included in the control panel. This shows how many days until the next flush cycle is scheduled.
