Flushing and conditioning
: Allow water to flow for 10 minutes to flush unit then close faucet and allow unit to sit overnight
to condition. In the morning flush unit briefly before beginning service.
YOUR UNIT IS NOW IN OPERATION.
Note:
In some cases with low water pressure, the OUTLET sump may only partially fill due to an air block. If this happens,
turn off faucet and press top vent button until water level rises past the sealing point on sump.
Note:
It is normal for the
water to initially have some carbon fines (tiny black particles). It is also normal for the water to appear cloudy for
the first few
days and is safe to drink. The cloudiness is caused by small air bubbles that get displaced from the filters. If
you leave the water standing for a few seconds, the cloudiness will disappear. Running the unit for extended periods of
time will
NOT
help.
(E) MAINTENANCE
Caution:
If your unit is not used in winter, or will be subject to freezing temperatures, drain unit and remove
cartridges from sumps. Place cartridges in sink or on a paper towel to dry, which will occur in several days.
Note:
Lubricate Head O-rings (2502) after every cartridge change/cleaning and when draining for winter. Use food
grade silicone grease (i.e. Dow 111 compound) or any other non-petroleum lubricant.
Note:
Do Not
clean housing with organic solvents such as those found in sprays for cleaning products or
insecticides as these may cause cracking or crazing and lead to failure and leakage.

Note:
Cartridge life is directly dependant on water conditions and volume of water filtered. Excessive sediment may cause
more frequent replacement. Contaminants reduced by these filters/cartridges are not necessarily in your water.
**
Caution:
It is highly recommended to replace sumps at least once every 5 years to prevent costly repairs or
possible water damage. Record date of installation of new sump at the bottom.
(a)
Cleaning or replacing 1M Ceramic Cartridge
This cartridge is cleanable and reusable. The flow rate will gradually slow during use as
contaminants build up on the ceramic surface. The flow is restored by scrubbing the surface of
the cartridge as required using the abrasive cleaning pad (811-0) enclosed.
1)
Close supply valve and open faucet to release pressure in filter or press vent buttons on
top of either heads.
2)
Turn sump 1/8th turn to left and lower to remove and at same
time remove ceramic cartridge by twisting and gently pulling
downwards. Do not remove cartridge by unscrewing from adaptor
(2560). Transfer cartridge and sump to sink and dump water.
3)
To clean ceramic,
(
Note:
Please wear rubber gloves)
hold cartridge
in palm of hand with nozzle up and gently scrub entire surface with
abrasive screen cleaner (811-0) provided under running water.
Do not allow water to enter nozzle opening. DO
NOT USE SOAP OR DETERGENTS.
Scrubbing removes trapped particulates along with part of the ceramic.
4)
Replace ceramic cartridge if cartridge gauge (703-4) can be passed over the width of the ceramic
