Step 4: Provide Water and Condensate Drain Connections
• A two-pipe reverse return piping configuration is recommended as it equalizes the piping circuit lengths and delivers
even water flow to each unit. A direct return piping configuration may be used, but it may be difficult to achieve and
maintain proper water flow to the units.
• An air vent must be installed in the water distribution system.
• The supply and return water piping should be run through the wall or floor penetration and terminate with a ball valve.
The piping material used must comply with all local codes.
• Refer to: System Cleaning and Flushing procedures.
