Start-up Instructions (continued):
Periodic System Maintenance:
4. Water pressure will start to build in the RO system in about 2 hours. Carefully inspect all
fittings and connections. Check for leaks and fix if any are found.
5. Open RO faucet and let water flow through the system for a 24 hour period. Water will flow
heavily until the Storage Tank becomes empty, and then it will be a slow drip for the
balance of 24 hours.
6. Close RO faucet after 24 hour purge is complete.
7. RO system is ready for use.
NOTE: you will not have filtered water immediately. It will take 1-2 hours to completely fill the storage
tank to create liberal flow from the RO faucet.

Depending on which model was purchased the chart below will assist with replacement of
filters. The replacement filter can be obtained online at www.ghpgroupinc.com or at the retail
store where the system was purchased.
The prefilter and postfilter have a life expectancy between 6 to 12 months, depending on
the incoming water conditions and the amount of the water the system has used. You must
periodically replace the filters. This will protect the RO membrane from being destroyed by
Chlorine and also prevent the filters from plugging with sediment.
NOTE: Place a tray or towel under the RO system to catch any water drips before uninstalling the filter
sumps.
For Model VRO-3Q:
1. Refer “Un-install Quick Connect Filter” on page 6, to remove 1st stage of filter (left one in
front of the system).
2. Then, remove 3rd stage of the filter (right one in front of the system).
3. Discard the filters in a proper manner.
4. Refer “Install Quick Connect Filter” on page 6, to install the new filters in the reverse order,
install the 3rd-stage of the filter first, then the 1st stage of the filter.
5. Go to step 7.
