Sanitizing / Pressure Testing / Purging - EcoWater ERO-375 User Manual

SANITIZE THE SYSTEM
Sanitizing is recommended immediately after installa-
tion of the Reverse Osmosis system. It's also recom-
mended after servicing inner parts. It is important that
the person installing or servicing the system have clean
hands while handling inner parts of the system.
Complete the following steps to sanitize the system.
1. Turn off the water supply to the Reverse Osmosis
system, or remove prefilter to automatically shut off
water supply.
2. Open the Reverse Osmosis faucet. If the tank is not
already empty, allow the water to empty.
3. Use an eyedropper or other suitable tool, and com-
DO THE PRECEDING SANITIZING PROCEDURES
BEFORE PRESSURE TESTING.
1. Open the water supply shutoff valve to the RO.
2. Open the main water supply valve and several
house faucets to purge air from the system. Close
faucets when water runs smooth.
To purge the system, complete the following steps.
1. Open the RO faucet and let water flow through the
system for a 24 hour period.
NOTE: Water flow may be a slow trickle at this time.
SANITIZING THE RO SYSTEM
mon household bleach (5.25%).
4. Add 3 mL. of bleach into open end of yellow tank
tubing. Handle bleach according to bleach manufactur-
ers recommendations.
5. Connect yellow tank tubing to tank connector. Run
the length of 3/8" yellow tubing from the RO to the
connector (shutoff) valve at the top of the storage tank
(Figure 6).
6. Sanitizing the system will be completed during the
pressure test and purging steps below.
NOTE: The bleach must be removed from the system
before drinking the water. See purging instructions
below.
PRESSURE TESTING
3. Open the shutoff valve on the RO water storage
tank.
4. In about two hours, pressure will start to build in
the RO system. Then, carefully check all fittings and
connections for water leaks. Correct leaks if any are
found.
PURGING THE SYSTEM
2. Close the RO faucet after the 24 hour purging peri-
od is complete.
3. When the purging is finished, your Reverse
Osmosis system is ready for use.
