Note:
To ensure proper condensate drainage, it is very important to include
a slope. How to slope the convertible mid static ducted indoor unit
depends on if the application is horizontal or vertical, ceiling or oor
installation. See image at right for detailed information.

High Static, Mid Static, Low Static Ducted Gravity Condensate Pipe Connection
Mid-static Convertible (MA, horizontal installation; see below for vertical installation gravity condensate connections), Mid-static (M1/M2/M3) and
High-static indoor units (M2/M3/B8) have an auxiliary gravity condensate drain connection just below the condensate pump pipe connection on the
control panel end of the unit. This connection may be used instead of using the condensate pump. If the gravity drain is used, disconnect the IDU
condensate pump connector on the IDU PCB.
• Verify the unit is installed with a slight cant toward the gravity drain connection.
• Remove the rubber plug before connecting the condensate line to the indoor unit.
• The gravity condensate line must be equipped with a condensate trap for proper condensate ow (B8 only). MA, M1, M2 and M3 units do not
require a trap. Refer to Figure 42 for trap details.
• All horizontal segments of condensate pipe should be sloped a minimum of 1/4 inch per foot away from the indoor unit.
• Use materials acceptable by local code.

• Connect the drain piping to drain hole of vertical drain pan.
• Block the drain hole of drain pump to prevent air leaks.
