Two neighboring heat recovery ports are combined using a reverse Y-branch that is then connected to the one large indoor unit.

Piping in a horizontal direction from the outdoor Y-branch towards an outdoor unit or another outdoor unit Y-branch is greater than 6.6’. The inverted trap should be installed close to the outdoor unit Y-branch (no more than 6.6’ away). b.

    PLACEMENT CONSIDERATIONS Selecting the Best Location for the Outdoor Unit(s) Selecting the Best Location for the Outdoor Unit(s) DANGER • Do not install the unit in an area where combustible gas may generate, flow, stagnate, or leak. These conditions can cause a fire, result- ing in bodily injury or death.
  • Page 98 PLACEMENT CONSIDERATIONS Selecting the Best Location for the Outdoor Unit(s) Planning for Snow and Ice, continued. Choose an area where run-off from defrost mode will not accumulate and freeze on sidewalks or driveways. Properly install and insulate any drain hoses to prevent the hose from freezing, cracking, leaking, and damaging the outdoor unit. The system may take longer to provide heat, or heating performance will be reduced in winter if the outdoor unit is installed: 1.
