Page 3: Reverse Osmosis How It Works
The membrane is the heart of the system & needs to be protected. This is done by pre-filtration. Depending on the size of your system RO-MAN systems have two or three pre filters. For this purpose we are looking at a 3 stage 50 gallon per day system. -
Page 4: Starting Your Installation
Starting your Installation Preparation Determine the location for the installation of the system. Avoid locations where the system might come in contact with hot water pipes, other hazards or is exposed to extreme cold, an RO membrane will be damaged by frost. Determine the location for the discharge of the waste water. -
Page 5: Fitting The Pipes
Fitting the Pipes A Note on Push Fit Connections: The Push Fit Connectors are opened by pushing down on the Collet ring with two fingernails and pulling the hose at the same time. If your nails are not user friendly, then use a pair of pliers, a small spanner or any tool that can apply pressure on both sides of the Quick Connectors Collet. -
Page 6: Flushing The Filters
Flushing the Filters !! YOU COULD DAMAGE THE MEMBRANE IF YOU DO NOT DO THIS !! Disconnect the pipe from the GAC filter housing (see page 3 or 4) and temporarily connect the supplied green pipe to this connector. The other end to go to where the waste water will be discharged. Switch the water supply back on by opening the saddle valve (see previous Installing Supply Feed) by slowly turning the saddle valve wing nut counter clockwise until fully open. -
Page 7: Turning Off Your Ro System
“Quick Find” search box that can be found at the bottom left of the page. RO-MAN Options Pressure Gauge There are two reasons for fitting a pressure gauge: 1. To read the water pressure in order to check whether it is within specification. System pressure is very important too little pressure will make the production rate very slow and too much pressure will make the seals fail. -
Page 8: Maintenance
Flushing the System with the Flush Valve ALL RO-MAN systems are fitted with a flush valve, this valve is to extend the life of the membrane, the more often you can put the system in flush mode the better. Daily flushing is best but weekly is ok. All you need to do is open the flush valve for 2-3 minutes each time, this lets the water blast away any build up in the membrane. -

Troubleshooting It's OK to contact your Retailer or send RO-MAN an email helpdesk@ro-man.com. It is best to try first and remember, we cannot see it from here digital photos are great. All problems are fixable and in general they will show up in the first 24-48 hours after the system is fully charged. - Page 11 RO-MAN For assistance and enquiries please contact the support team: helpdesk@ro-man.com Page 11 of 11...
