Turn the faucet in a counter­clockwise direction and re­move the faucet from the dis­penser. Unscrew the faucet
cap from the faucet body and
disassemble all faucet parts.

detergent, the second sink

with a sanitizer solution (75°F

warm chlorine solution of at
least 50-100 ppm) and the
third sink is used for clean
rinse.

Slide the loaded brew funnel
into the funnel rails until it
stops. Place the power switch
in the ON position. Momen­tarily press and release the
START switch.

Use a small brush (BOM

scrub the faucet body.

When tea no longer drips
from the funnel tip, carefully
remove the brew funnel and
discard the used tea pouch.
Return the power switch to
OFF to prevent a false start.
Thoroughly clean and sani­tize the brew funnel and fun­nel tip screen.

Allow the parts to soak in a
sanitizer solution for a mini­mum of ten minutes.

Fresh tea is available at the
faucet. Drain the reservoir
before starting another brew
cycle.

STEP 5

Remove the faucet parts from
the sanitizer solution and
rinse thoroughly. Allow parts
to air dry over night.
