Sanitize, Pressure Test & Purge
Sanitize:
NOTE:
Sanitizing is recommended upon installation of the RO system, and after servicing
inner parts. It is important for the service person to have clean hands while handling
inner parts of the system.
IMPORTANT: Be sure to remove the RO membrane and both filter cartridges as follows, before
sanitizing. Chlorine will destroy the RO membrane cartridge.
1. Be sure the water supply to the RO is turned off, and the RO faucet is open to relieve pressure.
2. Remove the RO membrane sump by twisting 1/4 turn left (J). Remove the RO cartridge from
sump. Place the cartridge in a clean plastic bag.
3. Be sure the o-ring seal is on the sump. Replace the RO sump by turning to the right (C,) to lock.
4. Remove the postfilter sump, turning to the left. Take the cartridge from the sump and place in the
plastic bag. Replace the sump by turning to the right (5,,) to lock.
5. Remove the prefilter sump and cartridge. Also place this cartridge in the clean bag.
