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 filtration assembly, storage tank, faucet,
installation hardware, RO membrane, cartridges and tubing.
Check to see that the air supply in the empty tank is approxi-
mately 7 psi (48 kPa). Adjust it if necessary. To reduce the
risk of cartridge contamination, 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. 8), 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.
To reduce the risk of eye injury while drilling counter-tops
for faucet installation:
•
Safety glasses
MUST
be worn during the sink hole drilling op-
erations.
IMPORTANT NOTE
• If desired, sprayers can be disconnected to provide a suit-
able mounting hole for the RO faucet. A pipe cap or plug
will be required to seal the sprayer connection.
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 non-air gap faucet)
•
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 non-air gap faucet)
•
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 bit pressure
at a slow speed (300-400 rpm).
4) Insert the pilot tip of the spring-loaded porcelain cutter into
the pilot hole.
5) Drill the porcelain/enamel using the spring-loaded porcelain
cutter, making certain a complete ring has been cut through
the porcelain/enamel to the metal base.
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 NOTE
• When using a porcelain cutter it is critical that it is always
in a sharpened condition. Dull cutters are known to chip
sinks.
Drilling 7/8” diameter hole through countertop or stainless steel sink:
1. Locate area to be drilled. Mark center of hole with center
punch.
2. Drill hole with 7/8” drill bit suitable for countertop materials or
cast iron/stainless steel.
3. With grinding wheel or file, smooth out any rough edges.
