Sanitizing The RO Filtration System
For the highest quality water from your Aqua-Pure ® RO drinking water fi ltration system, it is important to
routinely sanitize both the storage tank and the RO assembly.
When to Sanitize the Storage Tank
A) Upon start-up as described in Section 5 of the Installation Manual. NOTE: Standard Aqua-Pure RO
storage tanks need a special sanitizing agent which is activated when the storage tank is initially fi lled.
(See Section 5 in the Installation Manual.)
B) After any servicing or routine maintenance which involves the prefi lter(s) or membrane.
Refer to Section 5 Steps D through K to Sanitize Storage Tank.
How to Sanitize the RO Assembly

• New pre and post cartridge
• Common household bleach (5.25% NON-scented)
• Standard eyedropper or equivalent
A) Shut off feedwater valve and tank ball valve.
B) Follow instruction for changing prefi lter and postfi lter.
C) Before attaching new cartridge(s), use eye dropper to inject one teaspoonful (approximately 5 ml) of
household bleach into the center of each fi lter cartridge.
D) Turn on feedwater valve and tank ball valve.
E) Open faucet to allow tank to drain.
F) Close faucet valve and allow system to run for at least one hour.
G) Drain tank and discard water. NOTE: If any objectionable taste is noticed, drain tank again and allow
