and QL2-2K Plus Water Filters reduce chlorine taste & odor. The QL2-OCS
2
and QL2-2K Plus
also reduce dirt and rust, and inhibit the formation of limescale which builds up on the brewer heating elements and in the
reservoir.
PROCEDURE
The following instructions provide for installation of a QL2-OCS
2
or QL2-2K Plus Filter regardless of whether or not the brewer is
already installed. The label on the OCS and QL2-2K Plus cartridges illustrates and explains the procedure for cartridge insertion
and removal from the filter head. The filter cartridge should be placed into the head after the system has been installed.
1. Install the QL2-OCS
2
or QL2-2K Plus as close to the brewer as possible. Do not connect this filter to any other equipment.
Connect only to the cold water line and do not expose it to high temperatures.
2. Select a location for the filter [nominally 4 x 4 x 13.5 inches long (10.1 x 10.1 x 34.2 cm) including a 2.5-inch (6.3 cm)
drop-down clearance for cartridge changes]. Write the installation date and anticipated cartridge replacement date in the
space provided on the cartridge label. The QL2-OCS
2
and QL2-2K Plus Cartridges should be replaced every 12 months or
after 1,500 gallons or 3,000 pots have been brewed, whichever occurs first.
3. If required, shut off the incoming water supply and relieve pressure in the tubing. Cut the tubing, allowing a 4-inch
(10.1 cm) space for the filter installation between the water supply and the brewer water inlet.
4. Install compression fittings into each port of the head. Use a good grade of pipe dope or plumber tape on the body threads.
Do not overtighten the fittings.
5. Slide compression nuts up the tubing (threads toward tubing ends). Slide a ferrule onto each tubing end (brass for copper
tubing, plastic for plastic tubing). Insert a tube insert into plastic tubing.
6. Position the QL2 head assembly so that the arrow shown on top of the head corresponds to the direction of water flow and
attach the incoming cold water supply to the inlet of the head.
7. Connect the filter outlet to the brewer water inlet line. Use compression or flare fittings to make water connections to
the brewer.
8. Mount the head to the wall using the screws and star washers provided.
9. Install the QL2-OCS
2
or QL2-2K Plus Cartridge into the head following the instructions on the cartridge label.
10. Turn on the water and check for leaks.
NOTE: The QL2-OCS
2
or QL2-2K Plus Cartridge must be flushed before use by running water through it at maximum flow for
five (5) minutes to purge the cartridge of air and establish precoat.
For installations in Massachusetts, the Commonwealth of Massachusetts Plumbing Code 248 CMR shall be adhered to.
Consult your licensed plumber for installation of the system.
