Remove the nuts from the Shut-off Valve.
Wrap the Teflon tape onto the Shut-off Valve.
Install the Shut-off Valve into the cold water adapter.
Wrap the Teflon tape onto the cold water adapter.
Loosen the cold water flex line at the faucet.
Wrap the Teflon tape onto the cold water flex line. Then install the Inlet Adapter.
Re-install the cold water flex line onto the adapter and tighten.
Slip the nut from the stop valve over the blue tubing.
It is recommended that you soak the tubing into warm water for a moment.
Then insert the blue tubing onto the valve. Tighten the nut.

Remove the 3M sticker on the bottom of the protector.

Re-install the blue lock clip

Make sure to position the Anti-leak Protector on the floor correctly.
If there is any leaking from the system or water dripping on the floor, the Anti-leak Protector will cut off the water supply to the system to avoid the further leaking. Then you will need to replace the Anti-leak Protector.

Remove the yellow cap from the last stage of the System.
Connect the yellow tubing (the other end has been connected with the RO Faucet)to the filtration System .
Drill a hole at a desired location on the drain pipe.

PROBLEM	CAUSE	SOLUTION
1. Milky colored water	Excessive air in the filtration system.	Air in the system is a normal occurrence when the RO system is initially installed. The milky color generally disappears within 1-2 week of normal use.
2. Noise from faucet	Air gap in the faucet and related tubing.	Turn the faucet on and let water flow for some time.
3. Slow flow to the pressure tank	It often happens when the System is starting up and the air pressure in the pressure tank is low.	Normally it takes 4-6 hours to fill the tank. Low water pressure and /or low temperature may cause the slow flow. Add pressure in the pressure tank.
4. Slow flow from the faucet/ Small capacity of water	A. Low water pressureB. The tubing has crimps.C. Pre-filters are blockedD. Membrane is blocked	A. This system requires minimum 40 psi water supply pressure.B. Keep tubing straight.C. Replace the 3-stage pre-filters.D. Replace the membrane.
5. Water taste or smell is not good.	A. Post carbon is depleted.B. Membrane is depleted.C. Pressure Tank is not clean.	A. Replace the post carbon filter.B. Replace the membrane.C. Drain the pressure tank and refill it overnight
6. No waste water drained	The Flow Limiting Valve	Replace the Flow limiting Valve.
7. Leaks	A. Fittings are not tightened.B. O-ring is missing or aged.	A. Tighten fittings as necessary.B. Contact your local dealer.
8. Leaks on the draining pipe	The hole of the Drain Saddle does not align appropriately.	Realign Drain Saddle.
