Installation procedures for stainless steel sinks
Recommended tools:
• Center punch
• Variable speed drill
• High speed drill bits
• Greenlee chassis punch (7/8” or alternative size, 9/16” for non air
gap faucets)
• Protective gloves & eye protectors
Procedures:
A. Center punch small indent for hole.
B. Drill the required pilot hole.
C. Set-up the chassis punch per instructions and tighten nut to cut the desired hole size.
D. Clean up sharp edges with file.
2. Mounting the faucet
Read the instructions supplied with the air gap faucet carefully before installing.
Disassemble hardware from the threaded nipple, except for chrome base plates and rubber washers.
(Rubber washers may be replaced with bead of plumber’s putty for neater appearance.) Feed the threaded nipple through sink or counter mounting
hole and orient the faucet. From below sink or counter, assemble the white spacer, flat washer and hex nut on threaded nipple and tighten by hand.
(White spacer used for thin wall stainless steel sink or counter;open end up; open side toward air gap). After checking faucet orientation, tighten
with a wrench until secure.
3. Feed water angle stop valve installation
The John Guest Angle Stop Valve connects between the supply valve and riser, to the main water supply line. Read the instructions supplied with
angle stop valve carefully before installing.
1. Shut off water supply at brass/chrome supply valve.
2. Disconnect riser from brass/chrome supply valve.
3. Ensure that the sealing gasket is fully seated into the angle stop valve female thread.
4. Install angle stop valve on supply valve.
5. Connect the riser to the angle stop valve.
4. Drain saddle clamp assembly installation
Prior to proceeding it is important to inspect the condition of drain pipes to make sure they are not thin and frail.
Drain saddle clamps are designed to be installed on standard 1-1/2” OD drain pipe. Install drain saddle clamp approx. 6” above (and before) the trap
and on the vertical or horizontal tailpiece. Never install a drain saddle clamp close to the outlet of a garbage disposal or plugging of the RO drain
line may result.
Drain saddle clamp installation
Procedures
1. Position drain saddle clamp front plate at selected location and mark for the opening.
2. Drill 1/4” hole at mark through one side of pipe. DO NOT penetrate the opposite side of the pipe.
3. Position both halves of drain saddle on drain pipe so the front plate foam gasket hole and tubing connection hole lines up with the drilled 1/4”
hole.
4. Secure drain saddle clamp on pipe with screws and nuts provided. (Do not over tighten and make sure there is equal space between saddle halves
on each side.)

B. Feed Water Saddle Valve Installation
Decide on location. Do NOT connect to a
hot water feed line. If you are not sure of the
supply, run the hot water and feel the supply
piping. Water over 100°F may cause permanent
damage to the R.O. Membrane. (Refer to Fig. 3).
1. Shut off the water supply and drain the line.
2a. To install on (soft) Copper Tubing supply
line:
•Turn the Handle of the Feed Water Saddle
Valve counter clockwise (outward) until the
lance does not protrude from the gasket. It
may have to be pushed in.
•Assemble the Feed Water Saddle Valve on
the tubing.
– for 3 /
8
" OD tubing use the back plate side
with the small groove to prevent distortion of
the tubing.
– for larger tubing (up to 5 /
8
" OD) use the
large groove of the back plate.
•Assemble and tighten the brass screw.
•To pierce the tubing, turn the Valve Handle
fully clockwise (inward). A small amount of
water may escape from the outlet until it is
fully pierced.
•When you feel the Valve Handle firmly
seated in the clockwise direction, the
copper tube is pierced and the valve is
closed.
2b. To install on (hard) Steel or Brass Tubing
supply line.
•The supply line should now be drained. Use
a battery powered or properly grounded drill
to avoid shock hazard.
•Drill a 3 /
16
" hole in the supply line; (do not
drill through the opposite wall).
•Turn the handle to expose the lance no more
than
3
/
16
" beyond the rubber gasket.
•Place the body of the valve over the hole so
that the lance fits into the hole.
•Assemble and tighten the brass screw.
•Turn the Valve Handle clockwise (inward)
until firmly seated. The valve is closed.
3. With the Feed Water Saddle Valve closed,
open the sink faucet and the water supply
and allow the water to run for a few minutes
to flush any debris caused by the installation.
•Close the faucet and check the Feed Water
Saddle Valve for leaks.

C. Drain Clamp Installation
Choose the drain outlet location per Sec. III, C.5.
The following are instructions for discharging
into the sink drain pipe. (Refer to Fig. 1).
1. Position the Drain Clamp on the sink drain
pipe above the drain trap. Allow room for
drilling. Tighten securely.
2. Use a battery powered or properly grounded
drill. Using the Clamp port as a drill guide,
drill a
7
/
32
" hole through the wall of the drain
pipe. Do NOT penetrate the opposite side of
the pipe.
