PORCELAIN/ENAMEL/CERAMIC SINKS

IF YOU ARE READING THIS SECTION, PROFESSIONAL INSTALLATION IS HIGHLY RECOMMENDED.

To reduce the risk of eye injury while drilling countertop for faucet installations:

• Safety glasses MUST be worn during the sink hole drilling operations.

Drilling Hole through Porcelain/Enamel/Ceramic Sinks

Recommended Tools:

•

Variable Speed Drill

•

Porcelain Cutter Tool Set (9/16" Size)

•

Plumber's Putty

Note: It is important to understand this procedure.

1. The glassy layer of porcelain/enamel/ceramic must be scored through to the metal base, creating a disk.

2. This disk must be removed while protecting the surrounding decorative coating against chipping or fracturing.

3. The base metal must be drilled through to complete the hole.

Procedure:

1. Mark center for 9/16" hole.

2. Form a dam of shallow putty around hole location and ﬁ ll with enough water to lubricate carbide drill bit.

3. Carefully drill pilot hole through porcelain/enamel/ceramic and base metal using a carbide pilot drill bit. Always oper-

ate drill with light pressure at slow speed (300 - 400 rpm).

4. Drill porcelain/enamel/ceramic using special 9/16" cutting tool, making certain a complete ring has been cut through

to the sink's metal base.

5. Change to metal cutting drill bit and drill out the center of the ring, making sure not to contact other rim of decorative

coating. Cut through metal sink base.

FILTER REPLACEMENT INSTRUCTIONS

To reduce the risk associated with property damage due to water leakage:

• The disposable replacement ﬁ lter must be replaced every 6 months, at the rated capacity or sooner if a no-

ticeable reduction in ﬂ ow rate occurs.

1. Grasp installed ﬁ lter and turn to the left (counterclockwise) until ﬁ lter comes to a complete stop. Gently pull down-

ward to remove.

2. Remove replacement ﬁ lter from box, and remove sanitary protective cap from replacement ﬁ lter. Ensure both o-rings

are present on the new replacement ﬁ lter and are seated into grooves; moisten o-rings with water. DO NOT use any

petroleum products to lubricate the o-rings.

3. Align tabs of new replacement filter with existing filter head and insert new replacement filter into head. Turn

filter to the right (clockwise) until filter stops.

4. Open the dedicated faucet and flush new replacement filter for four (4) gallons (approximately 5 minutes)

before use. It may sputter as it releases trapped air.

5. Close dedicated faucet. System is now under pressure and can be inspected for leaks. Repair any leaks as

needed before continuing. The system is now ready for use.

Water leaks at push-in connections:

Push tubing in as far as it will go. If leaking continues, shut off water at the cold water supply valve and remove water

line by pushing in on the connector collar while pulling the tubing away. Inspect tubing for cracks and scratches. If tub-

ing is cracked or scratched, simply cut that portion away and reinsert tubing into push-in ﬁ tting.

Make sure tubing is cut straight. If not, recut correctly. Refer to Figure 3.

If water leaks, please verify that the o-rings are properly seated in their grooves.

Water does not ﬂ ow from the drinking water system faucet:

Check to see if the main water line valve is open, allowing water to ﬂ ow to the ﬁ lter.

Water appears cloudy or air comes out of the drinking water system faucet:

Flush the ﬁ lter for four (4) gallons (approx. 5 minutes) to remove any trapped air.
