Pressure Testing / Purging - EcoWater ERO-385 Manual

1. Remove the plastic wrap from the prefilter, postfilter
and RO membrane cartridges.
SANITIZE THE SYSTEM
Sanitizing is recommended immediately after installation
of the Reverse Osmosis system. It's also recommended
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-
mon household bleach (5.25%).
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.

PURGING THE SYSTEM
2. Install the cartridges onto the RO system head
assembly, where shown in the figure above. Turn car-
tridges to the right to tighten.
4. Add 3 mL. of bleach into open end of yellow tank
tubing. Handle bleach according to bleach manufacturers
recommendations.
5. Connect yellow tank tubing to tank connector. Run
the length of 3/8" yellow tubing from the RO to the con-
nector (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.
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 connec-
tions for water leaks. Correct leaks if any are found.
2. Close the RO faucet after the 24 hour purging period
is complete.
3. When the purging is finished, your Reverse Osmosis
system is ready for use.
