5) Firmly pull the module away from the head. (It may be
necessary to twist the module slightly from side to side.)
6) Remove the new RO membrane module from its protective
wrap. (Double check to see that it is the correct replacement by
comparing the labels.)
7) Remove the sanitary plastic cap atop the module.
8) Ensure both o-rings are present on the replacement fi lter and are
seated into grooves; moisten o-rings with water. DO NOT use any
petroleum products to lubricate the o-rings.
9) Connect the new red SFC reject tubing (supplied with replacement
membrane module) by inserting it into the fitting at the bottom of
the new RO membrane module as far as it will go, and into the
faucet adapter. Line up the module ears, insert the module and
push it into the head until it is fully seated. Twist the module 1/4
turn to the right (clockwise) to lock it into place.
10) Open the cold water feed valve, and carefully check for leaks. Carefully
inspect the fitting at the bottom of the new RO membrane module.
11) For sanitization of RO system please follow instructions below in
Section D.
12) Flush membrane module - refer to Section M, Step 1 and 2 on
page 8.
D. SANITIZING THE 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 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 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 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 lift up on 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. (See Fig 8)
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.
7)
Life up the handle of the RO faucet and allow contents of tank to
drain completely into the sink.
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.

Remove the red SFC tubing from
the fitting before completely

WARNING
To reduce the risk associated with ingestion of water contaminated
with sanitizer:
• After installation, sanitizers
must
be fl ushed from the system
before fi rst use as directed within the installation instructions.
