Ro-Man 200 GPD Installation Manual - Troubleshooting
Troubleshooting
It's OK to contact your Retailer or send RO-MAN an email via
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.
1) "I have leakage from a push-in fitting"
Solution: The push-ins rarely leak but on the rare occasion that they do try pushing the line in harder. If this fails take the line out
and check the end of the tube. Is it a clean square cut?? If not, take a pair of sharp scissors (or a sharp knife) and cut it then push
it in again, firmly.
2) "The system is making water very slowly"
Solution Time in seconds how long it takes to produce exactly one pint of product water. Multiply the measured seconds by 8 to
give time in seconds to produce 1 gallon and then divide 86,400 by the time to produce 1 gallon. You now know how many
Gallons Per Day (GPD) the system is producing. Make a note of the psi on the pressure meter and take the temperature of your
feed water.
Go to
http://www.ro-man.com/ro-man_support.html
and choose the “System Support “ option using the down arrow select
your RO-Man system and then input your psi , temperature and if known your input TDS. Click on “Calculate” if the answer to
this calculation in UK gallons is markedly higher than what you are producing please contact
helpdesk@ro-man.com.
Remember
that your psi needs to be 40 psi if it is not again please contact us.
3) "The system is not making water "
Solution This is almost always a psi problem. 40 psi is about as low as you can go. If the psi is low it can be a bad hole on the feed
water pipe. try drilling it out. If you have good psi to the inside of the pre-filters, then check the following:
a) Check to see if the water is flowing out the Green discharge line - if so, then the membrane is getting water.
b) Disconnect the blue line from the RO membrane housing - is there any water?
c) If the Green line is flowing and the blue is not, it may be blocked, check the valve at the RO Housing. There are two outlets on
the out end of the RO membrane. One goes to the discharge saddle and the other is purified water. This outlet has a built in
check valve inside the chrome plated brass part, take it out - is there any water there?
d) If unit has been in service for a while, the problem is probably clogged filters. Pull the filters out, test them one at a time by
putting them into the first filter position and seeing if it flows. Clogged filters are usually only associated with well water or with
really turbid water.
e) The RO Membrane has silted up. Very rare unless very bad feed water. The RO Membrane is self-flushing. Try back-flushing
the membrane.
4) "My filters are leaking"
Solution:
Loose O-Ring. Take housing off and make sure they are properly aligned. Housing not tight enough - tighten.
5) "I have leakage from a screw-in connector"
Solution:
a) Not tight enough - gently apply pressure - too much and you will strip the threads
b) If that does not work, remove and apply PTFE tape.
Last tip: nothing lasts forever
The system you bought will eventually wear out. The things that wear out are the RO membrane, the flow restrictor and the
green line get caked with the junk that is being sent down the drain. The rubber "0" rings will get old and crack, just like gaskets
on your car. If you start replacing them one by one, you are going to go crazy and will spend lots of time and money. A
membrane will cost around £40.00 to replace. The bottom line is that it is cheaper and easier just to junk the system (or keep it
for parts) and buy a new one every few years, or when the RO membrane dies. You will know when the RO membrane dies. The
water will start tasting bad. We recommend that you invest in a TDS meter and check the TDS of the feed water and the TDS of
the RO water. When there is no difference, the RO is dead. It will not happen overnight. There will be a gradual decay.
Remember-change filters every 6 months. If you have fairly heavy duty use, adjust accordingly to fit in with throughput
specifications.
