System Start Up
1. Turn on the Water Supply
• Allow the system to start filling with water.
2. Fast Flush the System
• Open the R.O. faucet and position the drain barrel in the fast flush
position (see figure 3).
3. Reposition the Drain Barrel
• Once the air has been purged from the system, position the drain
barrel in 1 of the 2 service positions (see figure 4). The storage tank
will continue to fill with water.
4. Check for Leaks
• If a leak is present, make the necessary repairs.
5. Fill the System
• When the water stops flowing to the drain, the system should be
fully pressurized and the storage tank should be filled with water.
6. Drain the Storage Tank
• Open the R.O. faucet and drain all the water from the storage tank.
7. Complete the Installation
• If a 24 hour-flush pre-installation is not performed by your local
dealer, it is important to open the faucet, let the system drip for 24
hours first.
• After the 24 hour water flush , close the R.O. faucet and allow the
storage tank to fill with water. When the storage tank is full, the
system will be ready for operation.
Routine System Maintenance
The storage tank should be drained and the system should be fast flushed
1 to 2 times per week.
To drain the storage tank, open the R.O. faucet and let the water run until
the flow turns into small drips. Close the R.O. faucet and rotate the drain
barrel 90o to the fast flush position(see figure 3).The sound of rushing
water should now be heard. Allow the system to fast flush for 5 to 7
minutes and then rotate the drain barrel to position#2 (see figure4).
!
Important Note: Do not attempt to reset or
remove the drain barrel screw. The drain barrel
screw is preset by your RainSoft Dealer and
should only be adjusted by a qualified
RainSoft Technician. Tampering with this part
may result in poor system performance, leaks
in the equipment and/or personal injury.
!
Important Note: It is common to experience
cloudy water, cloudy or hazy ice cubes and/or
air bubbles when the system is new or after the
filters/ cartridges have been changed.
