Pressure Test System; Step 6: System Startup - GE Merlin Installation And Maintenance Manual

THE BASIC REVERSE OSMOSIS SYSTEM

STEP 6: SYSTEM STARTUP

1. Inspect all connections.
2. If the flush tank is not installed, the 1/4-inch port on the manifold must be
plugged.
3. Position manifold horizontal with openings facing up.
4. Remove new membrane elements from plastic packaging. The black and
yellow tapes surrounding the membrane are an important part of the
membrane element and should not be removed.
CAUTION: Elements contain a foodgrade preservative. The use of
sterile/latex gloves is recommended.
5. Lubricate element O-rings, brine seals, and sump O-rings with silicone
lubricant.
6. Securely insert O-ring end of membrane elements into manifold.
7. Remove prefilter from packaging. Check that gaskets are in place.
8. Place prefilter in manifold.
9. Replace sumps and tighten until it bottoms out.

Pressure Test System

To check for leaks, the system must be filled with water and brought up to
operating pressure.
1. Open cold water feed valve slowly. Run at 1/2 open for a minute, then open
fully.
2. Open faucet until water runs.
3. Check for leaks.
NOTE: When the faucet is initially turned on, water may temporarily
sputter from the air gap until the air is purged. Allow 1 to 3 hours for any
trapped air noise in the system to subside.
4. Purge the system. Open the faucet and run the water through the RO system
for two to eight hours.
NOTE: A minimum of 2 hour flush is required to remove the food grade
preservative. After 8 hours performance will reach its stable maximum
performance
The RO system is now ready for use.
