• Electrical: See schematic in this manual
SETUP STEPS
NOTE: Some type of water filtration device must be used to maintain trouble-free operation.
In areas with extremely hard water, we suggest that a sedimentary, taste and odor filter be
installed. This will prolong the life of your brewing system and enhance tea quality.
1. Locate the brewer on a secure surface. Level it left to right and
front to back by rotating the feet on the 4 corners.
2. Connect a water line from the water filter to the brewer.
Plumb water lines. A 1/2" hose barb has been supplied for water
line connections. See page 3 for location.
NSF International requires the following water connection:
1. A quick disconnect or additional coiled tubing (at least 2x the depth of the brewer) is required so
that the brewer can be moved for cleaning underneath.
2. This equipment is to be installed with adequate back-flow protection to comply with applicable
federal, state and local codes.
3. Water pipe connections and fixtures directly connected to a potable water supply shall be sized,
installed and maintained in accordance with federal, state and local codes.
Use tubing sized sufficient to provide a minimum of 3.0 gpm for the ambient INLET WATER
(2 places) and CHILLED WATER connections.

3. Connect the CO or compressed air line.
4. Connect the brewer to an electrical outlet with the appropriate
amperage rating (see serial tag on brewer).
