Maintain Your
System (con't)

Preliminary Steps:
1. Check for any leaks that may exist from tubing connections or the faucet.
2. Check for flow to the drain. If flowing, close tank shut-off so you can check auto shut-off
operation
3. Test and record product TDS from faucet. Also observe if faucet stem is stiff to move.
4. Test and record feed TDS, and then calculate rejection percentage.
5. If rejection is acceptable - Shut off storage tank, remove tank supply tubing to collect
and record product flow, and water temperature.
6. Record feed pressure if needed by attaching a pressure gauge to feed line. Use the
recorded feed pressure and water temperature to check product flow rate against the
supplied chart. Membrane okay? Low production could be the result of partially plugged
prefilters. If so retest after filters are changed.
7. With feed line off begin draining tank.
The Aqua-Cleer RO manifold assembly may be sanitized with 5-1/4% liquid chlorine
unscented bleach.
1. Shut off water supply then remove all filters. Put bypass plugs in ports 2, 3 and 4.
2. Pour two tablespoons liquid chlorine bleach into the sanitizer cartridge and place in
port 1.
3. Turn on the water supply valve and the RO faucet to allow the system to fill with
water. Allow the water to flow through until the entire system for about 10 minutes
or until the sanitizing solution is through.
4. Install new filters, including the post carbon filter, and membrane if needed, or
reuse existing membrane. Some filters require flushing before use to remove dust
and fines. If an in-plant flush was not performed, use the single head assembly to
perform this using the feed line and drain lines available. Don't flush using the
RO manifold.
5. Replace the battery in the quality monitor if applicable.
6. Discard the first glass of water from the faucet.
7. Thoroughly check for leaks.
