Connecting Tubing into Filter (Figs 3, 4, and 5)
PLASTIC TUBING
• Cut tube ends square and straight. Do not deform tube (i.e., cause tube to compress its diameter so it is
no longer round).
• Avoid sharp changes in direction when routing tubing. Sharp turns cause tubing to ex and deform,
which reduces its ow capacity and may increase lateral stress on the ttings, causing leakage.
1. Remove red end caps from unit’s water inlet/outlet connections.
2. Push in tube from saddle valve through water lter INLET tting (Fig 3). Remove blue locking clip, if any.
3. Push in tube from faucet through water lter OUTLET tting (Fig 3). Reattach blue locking clip, if any.
Changing Filters (Fig 6)
NOTE: THIS MEGA UNDERSINK SYSTEM CONTAINS CARTRIDGES WHICH MUST BE REPLACED AT REGULAR
INTERVALS TO MAINTAIN PROPER PERFORMANCE. USE ONLY FACTORY APPROVED CARTRIDGES.
Use a drip pan to catch any water that may spill when the lter housings are removed.
• Close the saddle valve that feeds the lter.
• Release any pressure in the line by turning on the cold- and hot-water faucets.
• Loosen the sump by turning counterclockwise using the sump wrench that came with the lter. Careful! It will be full of
water.
• Remove and dispose of used lter cartridge. (Cartridges may be recycled. Visit www.crystalquest.com/crystal quest
policies.htm under Preventive Routine Mintenance instructions.)
• Clean the inside of the sump with hot, soapy water. Rinse well. (Remember that you turned the water o at the sink
you're working on.)
• Remove shrink wrap and insert the new lter cartridge in the sump. Cartridge must be installed according to the
directional arrow on the cartridge which indicates “This End Towards Cap”.
• Check O-ring(s). Lubicate with cooking oil if needed. Position O-ring(s) properly in the groove of the sump and tighten
by turning it clockwise. Do not overtighten. Do not cross-thread at the sump or inlet/outlet ports. If cross-threaded, do
not put or keep unit in service.
• Open the water valve slowly and ll the lter. Turn o the faucets and check the unit for leaks.
• Flush cartridge 3-4 times for 5 to 10 minutes to clear out media nes before using the water.
STEP 2 – Install the Saddle (Feedwater) Valve and Tubing (Fig 2)
CHOOSE THE VALVE LOCATION
• Choose a location for the valve that is easily accessible. It is best to connect into the side of a vertical water pipe. When it is necessary to connect into a horizontal water
pipe, make the connection to the top or side, rather than at the bottom, to avoid drawing o any sediment from the water pipe.
• Disconnect the cold water supply line. Attach and tighten the saddle valve connector assembly, being careful not to pinch or crimp any tubing or water supply line while
tightening. Use Teon® tape to ensure a tight t.
NOTE: The saddle valve clamps onto hard tubing or pipe. It will make its own hole in copper tubing but not in iron or brass.
For brass or galvanized iron pipe, drill a 1/4” hole in pipe before mounting saddle valve. If possible, use a hand or cordless drill
when drilling water pipe. If using an electric drill, be sure that drill, cord and outlet are all properly grounded.
NOTE: If water supply line is soft tubing, it is recommended to use a T-valve installation.
NOTE: Do not turn handle before installing or while installing saddle valve. To prevent damage to piercing needle,make sure
that piercing lance does not project beyond the rubber gasket.
NOTE: Leave handle in this position (valve closed) until lter installation is complete.
1. Hold backplate against tube.
2. Hold saddle valve against tubing in a position directly opposite backplate.
3. Tighten screw enough so saddle valve and backplate are held securely against tube.
4. Tighten screw rmly. Do not crush tube.
CONNECT SOURCE WATER FEED TUBING TO VALVE BODY USING COMPRESSION FITTING
1. Slide nut and sleeve onto tubing (in that order).
2. Install insert into tubing.
3. Install tubing with insert and sleeve into valve body.
4. Thread compression nut onto valve body. Tighten.
5. Turn saddle-tapping valve handle clockwise until it is rmly seated and piercing lance is fully extended.
CAUTION: When the supply line is pierced, the valve should be closed. Do not open valve until system is activated. Turn on
cold water supply. Check saddle-tapping valve installation for leaks. Allow water to run from faucet for a few
minutes to clear any debris in the line caused by installation.
NOTE: If ow from sink faucet is reduced, clean faucet aerator.

FITTINGS
• Fittings consist of three parts: a body, collet, and
a locking clip. Make sure outer surface of tube is
clear of marks or scratches for a length equal to
twice tube diameter. This allows O-ring to seat
properly against tube.
• Remove locking clip from body collet (A).
• Push tube through collet into body until it seats
rmly at bottom of tting. Replace the locking
clip around the collet. Not replacing the locking
clip may cause the tube to eject, resulting in water
damage (A, B).

REMOVE FITTINGS
• To remove a tube, turn o the water. Remove
locking clip.
• Push and hold collet against body (ring of the
connector) square against the tting while pulling
tube out.
• To reinsert a tube, cut 1/2” of tube from the end.
This will help prevent leaking. Replace the locking
clip around the collet.
CONNECT USING COMPRESSION
FITTINGS
• Slide compression nut over the end of
tubing.
• Connect compression nut to compression
adapter and tighten the compression nut
securely.

Mounting the Faucet:
Disassemble hardware from the threaded
nipple, except for chrome base plates and
rubber washers. (Rubber washers may be
replaced with a bead of plumber's putty
for neater appearance.) Feed the threaded
nipple through sink or counter mounting
hole and position the faucet. From below
sink or counter, assemble the white spacer
at washer and hex nut on threaded nipple
and tighten by hand (open end up; open side
toward air gap). After checking faucet ori-
entation, tighten with a wrench until secure
(Fig 1).

Tools and Material Recommended for Installation
Easy To Install
STEP 1 – Install the Faucet (Fig 1)
Faucet should be placed near the sink where drinking/cooking water is normally required. A 2" at surface is required to
mount the faucet if an existing hole for a second faucet is not available. The mounting thickness should not exceed 1-1/4". If
the sink has a sprayer, it may be disconnected for faucet installation. A pipe cap or plug will be necessary to seal the sprayer
connection. If making the faucet mounting hole (if sprayer or second hole is not used), check to make sure the drill does
not interfere with anything below. Center punch a small indent at the desired faucet location (2" at surface is required,
not exceeding 1-1/4" in thickness). Drill the required pilot hole of the chassis punch and tighten nut to cut the desired hole
size. Clean up sharp edges. The faucet should be positioned so it empties into the sink and the spout swivels freely for
convenience. If sink has a hole that can accommodate the faucet, no drilling is required. Proceed with mounting the faucet.
Preparing for Installation
