Note: When tank is empty, faucet will steadily
drip. This is the rate the RO system processes
water.
2.
With faucet handle in "open" position, measure
the rate of the steady drip from spout. Use a
graduated cylinder and watch with a second
hand to calculate approximate production in
gallons per day.
Note:
Milliliters per minute X 0.38 = GPD.
Ounces per minute X 11.2 = GPD
3.
Proceed
to
check
reject
flow
rate
by
disconnecting tubing at drain connection and
measure flow as described above.
Note: Proper ratio should be 2.5 reject water to
1 part of product water, on average.
4.
Close faucet and re-inspect system for leaks.
5.
Allow
system
to
process
water
for
approximately four hours, at which point tank
will be practically full.
6.
Open faucet again and allow tank to empty for a
second time.
Do not use this water.
7.
Wait another four hours to allow tank to re-fill.
Note:
If no objectionable tastes are noticed after
second tank draining, RO processed water is ready
for use. Otherwise, drain tank and re-fill for a third
time.
8.
At this point supply line to ice maker connection
(optional) may be opened.
Maintenance
Your RO system contains filters and membranes
which must be replaced periodically for proper
operation. (Please see page 1 for general change-
out recommendations.)
Note:
Change-out procedures may be amended,
depending on source water conditions.
To change filters and membranes follow these
procedures:
1.
Close feed water valve by turning it clockwise.
2.
Open faucet to allow holding tank to drain.
3.
Loosen
and
remove
filter
housings
using
wrench provided and discard cartridges and or
membrane.
4.
Wash the inside of the housings using mild
detergent and soft cloth.
Thoroughly rinse all
soap before reassembly.
5.
Replace filter cartridges and membrane before
sanitizing system.
Note:
The system should be sanitized before
installing the activated carbon post filter cartridge.
Sanitizing instructions
To sanitize system follow these procedures with the
feed water valve closed:
1.
Close feed water valve.
2.
Open faucet to drain storage tank to sink.
3.
Remove pre-filters & membrane from housings.
4.
Use 5-1/4% unsented bleach, like Clorox.
5.
Add one cap (2 tsp or 10 ml) of bleach to each
pre-filter housing and the membrane housing.
6.
Carefully reinstall housings without sediment,
carbon pre-filter or membrane installed.
7.
Slowly open feed water valve to allow water to
mix with bleach and refill the housings and tank.
8.
Open faucet to allow water to fill lines. Close
faucet when water begins to drip from spout.
9.
Let system stand for approximately 15 minutes.
10. After fifteen minutes do in the following order:
Close feed water valve.
Close holding tank valve while faucet is
open to release pressure.
11. Carefully remove housings and empty them.
12. Remove protective wrap from pre-filters and
membrane and install them in the appropriate
filter housings. Hand tighten and snug with
wrench if necessary.
13. Replace post carbon in-line filter if necessary.
Note:
Be sure to check o-rings are in place when
installing cartridges in filter housings. Damaged or
incorrectly placed o-rings will cause leaks.
14. Disconnect product water tubing from the
holding tank and put 50 drops of bleach into the
tubing. Reconnect tubing.
15. Slowly open feed water valve.
When water
begins to drip from faucet, close faucet and
open holding tank valve.
16. Discard the first two tanks of water produced,
as they contain chlorine.
Do not use this
water.
17. When faucet is first opened air and carbon
powder may be noticed. This is normal. Allow
filter to flush.
