Pressure Test - Aerus ORIGINS RO400 Manuel D'utilisation

STEP EIGHT – SANITIZE, PRESSURE TEST
& PURGE SYSTEM
SANITIZE
Caution: Sanitization is recommended immediately after RO Filter System installation and any
inner-part servicing. The person sanitizing should have clean hands during this process.
1. Shut off water supply to RO system.
2. Open faucet. If tank is not empty, allow to drain until empty.
3. Disconnect white tubing from tank by unscrewing nut from tank connector fitting.
4. With included eyedropper, add 3ml household bleach (5.25%)
into open end of tank white tubing.
Warning: Bleach needs to be handled according to manufacturer's
instructions.
5. Reconnect tank and white tubing to tank connector fitting.
6. Sanitization will be completed during the following pressure test and purge.
Warning: Bleach must be completely removed from system
before drinking water. See Purge instructions below.

PRESSURE TEST

Warning: Complete sanitization prior to pressure test.
1. Open cold water supply valve to RO Filter System.
2. To purge air from the plumbing system, open kitchen faucet. Close faucet when water runs smooth.
3. Confirm RO faucet is closed.
4. Within approximately 2 hours, pressure will start to build in the RO Filter System. Carefully inspect all connections
and fittings while this pressure buildup occurs.
5. Check for leaks. If leaks are found, fix by ensuring all tubing is cut squarely and fully inserted.
Also confirm there are no scratches, dents or notches at tubing end. If there are, squarely cut 1" off and re-insert.
Notice: When RO Filter System is first pressurized, water may project
from faucet air gap hole until air is passed from RO Filter System.
PURGE
1. Open the RO faucet and leave it open until water begins to trickle out (this may take a few minutes, and the water
will come out slowly).
2. Close the RO faucet allowing the storage tank to fill with water. It may take 3 to 6 hours to fill the tank completely
depending on the production capability of the membrane, local water temperature and water pressure.
Notice: During the fill period, you may hear water trickling which is a normal occurrence.
3. After the storage tank has filled, open the RO faucet to flush the tank completely. You will know the tank
is empty when the flow rate from the RO faucet is down to a trickle. Repeat this step two more times.
The fourth tank can be used for drinking.
Notice: The flushing process should take about a day to complete.
