Step 4: Install Supply Fitting
Use the 2557 supply fitting if the water supply pipe under the sink attaches to a 3/8"
flex pipe from the kitchen faucet. If your piping is different or if you do not have a
shut-off valve under the sink, you can order Rainfresh CK538 or CKT38 valves
(depending upon your piping) directly from www.rainfreshstore.ca

IMPORTANT:

Before you install supply fitting, confirm the cold water pipe by running
hot water through your kitchen faucet and touching both pipes.
Now turn off the cold
water supply valve to
the kitchen faucet.
Step 5 : Start up
 Remove wrapping from carbon cartridge (CF2) and carefully place it

gasket facing up. Align the sump under the filter head and pull the
cartridge up with one hand and push blue gasket over boss of white
head (see fig 9). Pull sump up and rotate to right 1/8 turn to align the
sump grooves with lugs on the head (2501) to lock position (Fig 10)
