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 fill 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. Always operate

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 filter cartridge MUST be replaced every 12 months, at the rated capacity or sooner if there is a

noticeable reduction in flow rate, whichever occurs first.

1. Place towel under filter to collect any residual water during filter change-out.

2. Grasp filter and turn to the left (counterclockwise) until filter comes to a complete stop (water automatically turns

off). Water may leak momentarily from vent tube. This is normal. Gently pull filter downward to remove.

3. Remove sanitary protective cap from new replacement filter.

4. Ensure both o-rings are present on the replacement filter and are seated

into grooves; moisten o-rings with water. DO NOT use any petroleum

products to lubricate the o-rings.

5. Insert replacement filter into filter head assembly. Turn replacement filter

one quarter turn to the right (clockwise) until it stops. When fully engaged,

the top surface of the filter will be flush with the bottom of the filter head

assembly. (See Figure 7)

6. Reset PID: After the filter has been replaced, press the "CHECK/RESET"

button for four (4) seconds. A long "beep" sound can be heard and the

remaining capacity on the LCD screen is reset to 1,000 gallons.

7. Open faucet and run water for a minimum of 4 gallons (approximately 5

minutes). While system is flushing, check for leaks. Repair any leaks as

needed before continuing.

Close filter system faucet. System is now under pressure and can be

inspected for leaks. Repair any leaks as needed before continuing. The sys-

tem is now ready for use.
