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.
