7.2.1 DRILLING HOLE IN A PORCELAIN ENAMEL/ STAINLESS STEEL/ALUMINIUM SINK
Porcelain enamel sink / stainless steel sink / aluminium sink
A Ø 13mm hole is required for the faucet. It is recommended that you obtain a special ceramic drill bit for a
porcelain and/or tile sink/counter. When drilling the faucet hole for the sink/counter, you should wear eye
protection and exercise caution by following the below steps carefully.
1. Place a piece of masking tape or duct tape on the determined location where the hole is to be drilled.
2. Use a variable speed drill at slow speed with Ø 6mm drill bit, and drill a centering hole in the center of
the desired faucet location. Use lubricating oil to keep the drill bit cool while drilling.
3. Enlarge the hole using a Ø 10mm drill bit.
4. Enlarge the hole using Ø 13mm drill bit. Keep bit well oiled and cool, then drill slowly.
5. File or clean the surrounding area and then remove the masking or duct tape. (NOTE: the metal chips
on porcelain will stain very fast).
6. Pass the chrome cover plate and rubber washer according to the picture through the threaded mounting
tube at the base of the faucet.
7. Under the sink, install the white plastic locating washer, small metal washer and screw on the nut untill
it is tight against the underside of the sink/ counter.
8. With all fittings in place, thread the Tube Fastening Nut and Collet, insert the tubing into the faucet inlet
and tighten the nut.
9. Connect the other free ends of the 1/4” tubing according to schemes on page 11.
7.3 STEP 3: PRESSURE TESTING AND PURGING
7.5
1. Check all tubing to be sure there are no kinked.
2. Turn the Storage Tank Valve to OFF position.
3. Turn RO faucet lever to continuous flow ON position (handle pointed up).
4. Turn the cold water supply main valve on slowly. When the system is pressurized, check for leaks.
5. You will hear the air purging from the system and within 5 minutes, the water should start dripping
from RO faucet. Once the water starts to drip, allow 20 more minutes for the water to flow through the
system and purge all the air trapped inside the system.
6. After 10 minutes, turn the Storage Tank Valve to the ON position (handel is parallel to the tubing).
7. Turn the RO faucet handle to the OFF position. Now the purified water will start going into the storage
tank.
CAUTION: You must purge the first two tanks of water from the system prior to consumption of the
product water. Do not drink the first 2 tanks of water produced by the system!
8. Allow the storage tank to fill for 2 hours. Then open the faucet untill the tank is empty and the flow just
drips from the faucet.
9. Close the faucet and allow the storage tank to fill again for 2 hours. Then open the RO faucet and empty
the tank again. After discharging the contents of the Storage Tank twice, you can start enjoying the pure
water.
NOTE: Check for leaks daily for the first week after installaion.
