[Guide] Bevi 1.x and CT AlertCenter - Backflow Preventer Retrofit Required

Inspection Procedure

1.1.      The devices and parts must be inspected for cleanliness before assembly.

1.1.1.    Look carefully for any metal shavings within the threads

1.1.2.    If there is contamination and/or metal shavings, do not use the parts.  Contact the Bevi Quality team if unacceptable parts are found.

Assembly Procedure

2.1.       Tape Fittings

              2.1.1.    Apply 2-3 turns of tape around the threads

              2.1.2.    The tape should be installed on the threads of the fitting

in a clockwise direction so that the tape tightens as the fitting is tightened.  Applying tape in the wrong direction will result in the tape balling up during fitting installation.

              2.1.3.    Ensure there is no tape overlapping the fitting opening.

Install fittings

2.2.1.    Finger tighten the fittings onto the backflow preventer, one fitting per side.

2.2.2.    Using a wrench, tighten the fittings an additional 2-3 full turns.

2.2.3.    The fittings can be hand/wrench tightened while installed on the machine if they leak during testing.

Install backflow preventer

2.3.1.    Install the backflow preventer in the machine per the Machine Installation Instructions or Backflow Preventer Installation Tech Tip (see reverse page for details) Backflow Preventer Installation Guide Digital Version:

KFLOW-PREVENTER-INSTALLATION

• If there are leaks around the fittings, tighten the fittings as needed to stop the leak(s).
• If leaks persist, then there may be insufficient teflon tape. Proceed to remove fitting(s) and repeat Step 2.1.
• Check to make sure the fitting is not cross-threaded.  If so, then use a new fitting before proceeding.

• Turn off water to the system. NOTE: Check and turn off external Buffer Tank if present.
• Dispense water from the head unit to relieve pressure.
• Use tube cutters to cut the outlet side tubing ~3” from the end of the elbow fitting.
• Insert the inlet side of the backflow preventer on the tubing connected to the outlet side of the filter  so that the arrows point in the direction of water flow (away from the filter)
• Reconnect the other end of the cut tubing to the outlet end of the backflow preventer
• Attach red clip to both sides of backflow preventer -        Turn on the water supply.
• Check for leaks at the connection locations on the backflow preventer.

V1.5 Standup

• Turn off water to the system.
• Turn off Buffer Tank
• Dispense water from the unit to relieve pressure.
• Locate the check valve below on the unit’s plumbing shelf.
• Cut the (2) zip ties securing the check valve to the plumbing shelf.
• Remove the red clips and the check valve.  Discard the check valve.
• Insert the backflow preventer with the arrow pointing in the direction of water flow (away from the filter).
• Re-insert the red clips on either side of the backflow preventer.
• Turn on the water supply and Buffer Tank.
• Check for leaks at the connection locations on the backflow preventer.

• Follow the same procedure as the countertop machine.
• For the Bevi 2.0 a backflow preventer is already installed.
