OPERATION & MAINTENANCE
A. Normal Operation
1. Reverse Osmosis systems produce
drinking water at relatively slow rates, it can
take up to 3 hours 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 Shut-Off
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 Reverse Osmosis
system will function. Other uses for the
water are flowers, pets and rinsing
glassware.
With each use it is recommended that you
run 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
of 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 for 3-4 weeks or longer, it is a good
idea to re-sanitize the system and to
change the pre-filter and post filters.
B. Changing Filters
THIS REVERSE OSMOSIS SYSTEM
CONTAINS FILTERS WHICH MUST BE
REPLACED AT REGULAR INTERVALS TO
MAINTAIN PROPER PERFORMANCE. USE
ONLY FACTORY APPROVED FILTERS.
All individuals should take adequate
precautions when changing the filters,
including wearing protective gloves, to
avoid direct contact with the exhausted
filters.
The recommended interval for changing the
filters (not the Reverse Osmosis Membrane)
is every six (6) months. Typical T.F.C.
Membrane life expectancy is Five to ten
years with Water Softener prior to Reverse
Osmosis system. Local conditions may
dictate more frequent changes.
Use a drip pan to catch any water that may spill
when the Filter Housings are removed. Refer to
Fig. 1, page 3 for component location.
1. Close the Feed Water Ball 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 Pre-filter
and the Activated Carbon Pre-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 Pre-
filter.
• Use a good quality unscented liquid
chlorine household bleach.
• Add one capful of bleach (this is 2 tsp. or
10 ml) to the Sediment Pre-filter Housing
and install the Sediment Pre-filter. 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 Pre-filter Housing. Install the
Housing without the Activated Carbon Pre-
filter.
• The Dispensing Faucet should be open,
slowly open the Feed Water Ball Valve.
• As soon as the 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 Ball Valve,
close the Holding Tank Valve and open the
Dispensing Faucet to release the pressure.
• Remove the Activated Carbon Pre-filter
Housing and empty. Remove the wrapping
and install the Activated Carbon Pre-filter.
Firmly tighten the Housing hand tight only.
• Disconnect the tubing that runs from the
Holding Tank to the Tee (see Fig. 1, page
3). Put 50 drops of bleach (this is ½ tsp. or
10
