INSTALLATION QUICK VIEW • Please follow the color code for connecting tubing to the unit.
INSTALLATION (for under-the-sink installation) STEP 1: TAPPING INTO COLD WATER SUPPLY CAUTION: • The water supply to your RO unit MUST be from COLD water line . Hot water will damage your RO system. 1. Locate cold water shut off valve under the sink and turn it off. Open cold-water faucet to release the pressure, and make sure there is no water. 2. Put 3 turns of Teflon tape on threaded ends of the angle needle valve and feed water adapter. 3.
STEP 2: INSTALLING THE DISPENSING FAUCET 1. faucet base 2. small washer+ chrome plate 3. large washer 4. kitchen sink 5. bottom plate 6. lock washer 7. lock nut 8. tube insert 9. sleeve 10. faucet nut The faucet should be positioned with aesthetics, function and convenience in mind. An ample flat surface is required for the faucet base so that it can be drawn down tight. Also check the under sink area of the desired location to see if there is ample space to complete the faucet installation.
STEP 3: MOUNTING THE TANK BALL VALVE (for RD-106 only) Do not release air from the air valve on the lower side of the storage tank. It has pre-charged at 7-10psi at the factory. put Teflon tape, 6-8 turns screw on ball valve tight, push tubing through the nut, put tube insert, screw on the nut the tank can be positioned laying down or standing upright STEP 4: MOUNTING THE DRAIN SADDLE VALVE (don’t put in blue area) The drain saddle valve should fit most standard drainpipe.
STEP 5: SYSTEM START-UP 1. Make sure all tubing are not kinked. 2. Turn Tank Valve to OFF position, Faucet lever OFF. (for RD106 only) 3. Turn RO faucet lever to continuous flow posit ion. Lever points up. (for RD-106 only) 4. Turn cold water supply main valve on slowly. Also turn input ball valve ON. When the system is pressurized, check for leaks. If leak is found, tighten the connection. 5.
Changing Filters Procedures • • • • • • • • • • • Shut off the system by turning off the water supply, and turn off the tank valve, open the spigot to depressurize Prepare a towel under the unit for water spills Use a filter wrench (part no. 566, not supplied with the unit) or use hands to open the filter housing, unscrew it from right to left. Throw away the used filter, and clean the inside of the housing by rinsing or scrubbing it.
TROUBLE SHOOTING NOTE: Turn off the system before servicing. Installation Troubleshooting PROBLEM POSSIBLE CAUSE No or low water production 1. Feed water valve in not turn on 2. Tank valve is not turn on 3. Tubing is kinked 1. Housing is not tighten Leak at filter housing 2. Damaged or misaligned O-ring 3. Housing has cracks Leak at fitting thread 1. Not properly tighten 2. Fitting has cracks Bad-tasting water 1. Not yet flush the system 2. Tubing connection incorrect Milky/Cloudy water 1.
• • • RECHARGING TANK PROCEDURE PROBLEMS : When you turn on the spigot you get small water pressure and water flow. When you turn on the spigot, only a quick burst of water comes out of the system, then it dies down to trickles. When you turn on the spigot in the morning, you only can get less than a gallon of water. If you have above problems, you should recharge the tank. The tank should have about 7 psi of air pressure when it is completely empty.
