Chorus 3 RO or Chorus 2 RO/DI fills an external reservoir with purified Type 3 or Type 2 water, which then feeds a Chorus 1
to produce Type 1 water.
New system configuration:
1. Commission Chorus 3 RO or Chorus 2 RO/DI systems first, directing reservoir port: 4a to drain during this procedure.
(Please refer to operator manual Chorus 3 RO MANU39996 or Chorus 2 RO/DI MANU40003 for commissioning instructions)
2. Once the reservoir is full, open reservoir port:4a manual valve to Chorus 1 port 1: Feedwater inlet and continue to commission Chorus 1
with the PURELAB Dispensers connected.
3. Chorus 1 is set in pre-commisioning mode and will automatically direct water to drain during this procedure.
(Please refer to operator manual Chorus 1 MANU39998 for commissioning instructions)
Existing system configuration:
If you are connecting a PURELAB Dispenser to an existing system configuration, please ensure all of your products
are up to date and using the latest software. To find the software version of your existing system, simply turn the power off by the wall and back on
