SECTION V. OPERATION & MAINTENANCE
A. Normal Operation
1. It is normal for the Total Dissolved Solids
(TDS) of the water to be higher than normal
during the first 5 gallons of operation, this is
due to the sanitizing solution and the new Post
Filter. After this water is rinsed to drain, the
removal rate should stabilize at a value of
greater than 75%.
2. RO systems produce drinking water at
relatively slow rates, it can take up to
8 hours or more to fill the Holding Tank.
Normal operation is to let the Holding Tank
fill with water and then draw water as is
needed. When the pressure in the Holding
Tank falls to a given pressure (as the water is
being used) the Automatic Shutoff Valve
(ASO Valve) will start water production and
the system will refill the Holding Tank. When
the Holding Tank is full and no water is being
used, the ASO Valve will automatically shut
off the feed water to conserve water.
The more water that is used (up to the
capacity of the system) the better the RO
system will function. Utilize other uses for the
water, such as flowers, pets and rinsing
glassware.
With each use it is recommended that you
turn the tap for at least 10 seconds prior to
using water. This is especially important if the
water tap has not been used daily. After
periods of non–use, such as a week's vacation,
it is better to empty the holding tank and
allow the system to produce fresh water for
use. If the system is not used for3–4 weeks or
longer, it is a good idea to resanitize the system
and to change the Activated Carbon and
Sediment Filter.
B. Changing Filters
THIS RO SYSTEM CONTAINS FILTERS
WHICH MUST BE REPLACED AT REGULAR
INTERVALS TO MAINTAIN PROPER
PERFORMANCE. USE ONLY FACTORY
APPROVED FILTERS.
The recommended interval for changing the
filters (not the RO Membrane) is every six (6)
months. Typical C.T.A. Membrane life
expectancy is one year. Local conditions may
dictate more frequent changes.
NOTE: If the RO Membrane is to be replaced,
see Sec. IV, F.1–3, page 9, for the proper
procedure.
Use a drip pan to catch any water that may spill
when the Filter Housings are removed. Refer to
Fig. 1, page 1 for component location.
1. Close the Feed Water Saddle Valve by turning
fully clockwise and open the Dispensing
Faucet by lifting the handle. Allow the
Holding Tank to empty.
2. Loosen and remove the Sediment Filter and
the Activated Carbon Filter Housings. Discard
the filters.
3. Wash the inside of the Housings using a mild
detergent and a soft cloth. Do not use abrasive
cleaners or pads. Thoroughly rinse all soap
from the Housings before reassembly.
4. To sanitize the system and replace the filters:
NOTE: The system should be sanitized before
installing the Activated Carbon Post Filter.
•Use a good quality unscented 5¼% liquid
chlorine household bleach.
•Add one capful of bleach (this is 2 tsp.
or 10 ml) to the Sediment Filter Housing.
Remove the wrapping and install the
Sediment Prefilter only. (The O–rings
should be up, toward the Manifold Head,
on all filters.) Check the Housing
O–ring for proper position in its groove,
engage and firmly tighten the Housing hand
tight only.
•Add one capful of bleach to the Activated
Carbon Filter Housing. Carefully fill the
Housing with tap water and temporarily
install the Housing, without the Activated
Carbon Post Filter.
•The Dispensing Faucet should be open,
slowly open the Feed Water Saddle Valve.
•As soon as water begins to drip out of the
Dispensing Faucet, close the Faucet.
•Let the system stand for 15 minutes.
•At the end of 15 minutes, in the following
order, close the Feed Water Saddle Valve,
close the Holding Tank Valve and open the
Dispensing Faucet to release the pressure.
•Remove the Activated Carbon Filter
Housing and empty. Remove the wrapping
and install the Activated Carbon Post Filter.
Firmly tighten the Housing hand tight only.
