C.PREPARE THE APPLIANCE FOR INSTALLATION
Open the shipping carton and remove the components. Check to see that all of the installation parts are present. They should include the purification assembly, storage tank, faucet, installation hardware, RO membrane cartridge and tubing. Check to see that the air supply in the empty tank is approximately 7 psi (48 kPa). Adjust it if necessary. If an optional percent rejection monitor is selected, the probes should be installed at this time. Follow the instruction that came with the monitor. To ensure you the highest level of purity, the RO membrane cartridge has been shipped separately in a sealed plastic bag. Follow the steps below to install the RO membrane cartridge.
STEP 1: Cut open the sealed plastic bag and remove the RO membrane cartridge.
STEP 2: Remove the white plug from the fitting at the bottom of the cartridge by pushing in the small gray collet and pulling out the plug simultaneously (see Figure 6).
STEP 3: Connect the red SFC reject tubing by inserting the open end into the fitting at the bottom of the RO membrane cartridge as far as it will go. Take note of the tag attached to the SFC tube which indicates the outlet end.
STEP 4: Remove the red plastic cap from the top of the car- tridge.
STEP 5: Line up the cartridge ears (Fig. 10), insert the cartridge and push it into the head until it is fully seated. Twist the cartridge 1/4 turn counterclockwise to lock it into place. The final orientation should be such that the cartridge label faces towards the front and the fitting is located towards the rear.
D. MAKE THE FAUCET MOUNTING HOLE
A wide variety of RO faucet mounting situations may be encountered. The most common are stainless steel or ceramic on metal sinks. Consult your dealer for any other materials which may be encountered.
The faucet should be positioned so that it empties into the sink and the spout swivels freely for convenience.
If the sink already has a hole provided that can accommodate the RO faucet, then no drilling is required.
NOTE: If desired, sprayers can be disconnected to provide a suitable mounting hole for the RO faucet. A pipe cap or plug will be required to seal the sprayer connection.
IMPORTANT: It is mandatory that safety glasses by worn during the sink hole drilling operations in order to prevent eye injury.
Before drilling the hole, always check underneath the sink to ensure that nothing will interfere with mounting the faucet such as reinforcing ribs, support brackets or the cabinet construction.
Stainless steel sink, air gap or non-air gap faucet. Recommended tools:
•Center punch
•Variable speed drill and high speed drill bits
•Greenlee 7/8" chassis punch (alternate 9/16" may be used for a
•Protective gloves
Procedure:
1)Center punch a small indent at the center of the desired faucet location.
2)Slowly drill the required pilot hole for the chassis punch.
3)Set up the chassis punch per the instructions and tighten the nut to cut the desired hole size.
4)Clean up all sharp edges with a file if necessary.
Porcelain/Enamel/Ceramic sink on sheet metal or cast iron base; air gap or non air gap faucet.
Recommended tools:
•Variable speed drill
•Relton 7/8" porcelain cutter tool set (alternate 9/16" porcelain bit may be used for a
•Plumber's putty
It is important to understand what is involved in this proce- dure. First, the glassy layer of porcelain must be penetrated through to the base metal. Second, a center disc of porcelain must be removed while protecting the surrounding porcelain against chipping or fracturing. Third, the base metal must be drilled through to complete the hole.
Procedure:
1)Mark the center for the 7/8" hole.
2)Form a shallow putty dam around the hole area and fill it with enough water to lubricate the carbide drill bit.
3)Carefully drill a pilot hole through the porcelain/enamel and the base metal using a carbide type pilot drill.
Important: Always operate the drill with light pressure at a slow speed
4)Insert the pilot tip of the
5)Drill the porcelain/enamel using the
6)Change to the metal cutter. With a slow speed and light pressure, cut away the inner porcelain/enamel disc down to the base metal. Make certain that the cutter does not touch the outer rim of the cut porcelain/enamel. Continue with this bit to cut completely through the metal.
IMPORTANT: When using a porcelain cutter it is critical that it is always in a sharpened condition. Dull cutters are known to chip sinks.
