1. Introduction
2. What's included in the kit
Occasionally, customers may need to convert a Rainman RO unit in a case to have a remote valve /
gauge control assembly. This allows the system to be installed in the case, but access the control
assembly up to 5 metres (16 ft) away.
While it would be possible to re-use all the hardware, such as the pressure valve, pressure gauge,
and pressure vessel end caps, it is a much easier task to simply use a few new components. This
saves significant time on the rebuild process.
You will likely be installing the RO unit into your vessel. This can be done in the blue case or without
the case. See the detailed installation manual support page for further installation details.
What's included in the kit
The conversion kit includes a 5 metre (16 ft) high
pressure hose pre-installed with an RO end cap
on one end and a pressure valve / gauge control
assembly on the other. It also includes some
large cable tie straps for reassembling the unit
into the blue case.
