Hot Water System Overview
Installation
1. Place the system in the desired location. Ensure adequate
clearance so the the bypass valve can be operated when
necessary. NOTE: System must be operated in a vertical
position. Do not lay it down during operation.
2. Connect the Hot Water supply to the inlet bottom of the
OneFlow system. We recommend the use of the CPVC

Observe standard plumbing practices and local plumbing

NOTE: The OneFlow
system operates in the Up-Flow mode
