Installation Steps (cont.)
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.
