We recommend only using the RAE pump and VFD designed and tested specifically for the Hydrominder HP panel. The installation of another pump may have adverse effects on the panel components and dispensing process and void any warranty.

The panel and VFD will mount in 4 foot by 4 foot area on the wall. The pump should be installed near the VFD and requires a 1.5 foot by 1.5 foot area on the floor. We recommend before any installation, a site survey be completed per the Hydrominder HP User Manual.

It takes less than ten seconds while the whole panel stays in service. Each valve is on a dedicated line with an output ball valve and quick connects between the panel and injectors. Replacing a valve can be performed with virtually no downtime and without tools. Engage the valve's shutoff lever, unscrew its signal cable, unplug its air tube, remove its injector at the bottom quick disconnect, and then remove the valve from the panel at the top quick disconnect. Follow the steps in reverse when installing a new valve.

Even if less than 7 valves are needed, we recommend getting the 7 valve configuration to ensure your system is always running at its best. The extra valves and components can come in handy when switching chemicals or servicing valves. Instead of changing valve and chemical connections, switch the cables at the signal box for seamless transition and keep up with all the dirty cars.
