- STEP 6: SANITIZING,
PRESSURE TESTING & PURGING -
SANITIZING
Sanitizing
is recommended
upon
installation
of the
RO system,
and after
servicing
inner
parts.
It is im-
portant
for the service
person
to have clean hands
while
handling
inner
parts of the system.
CAUTION:
Be sure to remove
the RO membrane
and both filter cartridges
as follows,
before sanitiz-
ing. Chlorine
will
destroy
the RO membrane
car-
tridge.
1. Be sure the water supply
to the RO is turned
off,
and the RO faucet
is open
to relieve pressure.
2. Referring
to FIG. 9, page
11, press
inward
while
turning
the RO cap to the left (_)
to remove
from the
bracket/membrane
housing.
Remove
(use
pliers)
the RO cartridge
from
the housing.
Place
the car-
tridge in a clean plastic bag.
3. Be sure the o-ring
sealis
in the RO cap. Replace
the
RO cap and push
inward
while
turning
to the right
(_)
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
and tighten securely.
5. Remove
the preffiter
sump
and
cartridge.
Also
place this cartridge
in the clean bag.
6. If needed
to clean,
flush
the prefilter
sump
with
fresh water.
Then fill with water
to about
1" from the
top.
Add
1.0 ounce
of chlorine
(ordinary
5.25%
household
bleach...Hllex,
Clorox,
etc.) and mix in the
water.
Do not add chlorine
first. Concentrated
it will
attack
plastics.
7. Carefully
replace
the sump
on the prefilter
head
and tighten
securely.
8. Slowly
open
the water
supply
to the RO.
9. Open
the RO faucet
by locking
the lever upward
against
the spout.
10. Allow
water
to circulate
through
the RO system
until you smell
the bleach
odor. Then close the faucet
and allow
the RO to stand
idle for 20 minutes.
11. After the 20 minutes
open
the RO faucet
and run
water
until the bleach
odor
is gone.
12. Turn off the water
supply
to the RO.
13. Be sure your hands are clean. Then, repeat steps
1 - 5 and 7, only replace all cartridges.
Imp_'tant:
Refer to FIG. 9, page
11, and to page
12
when
replacing
cartridges.
The prefilter
(left side)
cartridge
has light gray coloring,
and the postfilter
(right
side) has blue
coloring.
PRESSURE
TESTING
1. Do the preceding
sanitizing
procedures
before
pressure
testing.
2. Open the water
supply
shutoff
valve
to the RO.
3. Open
the main
water
supply
valve
and several
house
faucets
to purge
air from
the system.
Close
faucets
when
water runs
smooth.
4. In about 2 hours, pressure
will start
to build
in the
RO system.
Then, carefully
check all fittings and con-
nections
for water
leaks.
Correct
leaks
if any are
found.
Note: When
the system
is first pressurized,
water
may "spurt"
from the faucet
airgap
hole until air is
expelled
from the RO system.
PURGING
RO MEMBRANE
Important
purging
instructions:
The RO cartridge
contains
a food grade preservative
that should
be re-
moved
before
using
water
from
the system.
The pre-
servative
will give product
water
an unpleasant
taste
and odor.
1. Allow
the storage
tank
to fill for about
4 hours.
Then
open
the RO faucet
until the tank is empty
and
flow stops.
2. Close the RO faucet
and allow the tank to fill again
for 4 hours.
Then
open
the RO faucet
and
empty
again.
Repeat
steps I and 2 to purge
the storage
tank 6 times. Then the RO system
is ready to
make product
water for use.
