D. SANITIZING THE PRO RO SYSTEM
Follow the sanitizing procedure for the storage tank and the filtration
assembly outlined below, followed by 24 hour flush with tank empty
and faucet open.
To help provide you with the highest quality water from your PRO RO
Drinking Water Filtration System, it is important to routinely sanitize
both the storage tank and the filtration assembly as noted below.
IMPORTANT NOTE: These procedures are only intended to be part of
a routine maintenance program only and are not designed to sanitize
systems that have become highly contaminated from misuse.
When to Sanitize the Storage Tank
•
Upon start-up as described in the beginning of this manual.
•
After any servicing or routine maintenance which involves the Pro RO
membrane module, carbon block post-filter, storage tank or faucet.
When to Sanitize the Filtration System
•
After any servicing or routine maintenance which involves the
sediment and granulated carbon replacement filters or the Pro RO
membrane replacement module.
How to Sanitize the Storage Tank and Filtration System
Sanitizing the storage tank generally requires:
Common household bleach (5.25% non-scented)
•
Eye dropper or plastic oral syringe
•
1)
Close the cold water feed valve and open the faucet handle to empty
the water in the storage tank. It should feel light when empty.
2)
Disconnect the 3/8" yellow tubing (system tank) from the ball
valve on top of the storage tank.
3)
Insert into the yellow tubing 1/2 teaspoon (3 ml) of household
bleach (5.25%). (See Fig 7)
4)
Reconnect the yellow tube to the tank ball valve.
5)
Close the RO faucet and open the cold water feed valve.
6)
Wait 4-5 hours.
Remove the red SFC tubing from
the fitting before completely
removing the RO membrane module
Fig. 6
To reduce the risk associated with ingestion of water contaminated
with sanitizer:
• After installation, sanitizer must be flushed from the system
before fi rst use as directed within the installation instructions.
7)
Open the RO faucet and allow contents of tank to drain completely
into the sink. It is recommended that a second tank of water be
discarded, so no objectionable taste is present.
8)
Sanitizing is now complete.
9)
If there is any residual chlorine/bleach taste in the next tank full,
drain tank completely a second time.
E. LONG TERM NON-USE
If the RO system is to be left unused for a long period of time
(greater than 30 days), install new replacement filters.
