Indoor unit installation
Horizontal application
Horizontal applications will normally be used in an attic
or crawl space. This type of installation requires supply air
plenum or duct to be connected to the supply collar and a
return air plenum or duct be attached to the unit inlet collar.
The supply ducts will be connected to the supply air plenum
and routed through the attic to a register in each room. Use
a Non-tape sealant such as mastic or an aerosol sealant to
prevent leaks in the ducts and the plenum.
The opposite end of the return air duct is attached to a return
filter grille housing. The filter grille is usually located in a wall,
just below the ceiling or the ceiling in a hallway. Use a Non-
tape sealant such as mastic or an aerosol sealant to prevent
leaks in the ducts and the plenum.
Horizontal right application (left to right)
The unit is shipped to be installed without modification in a right to left configuration. For left to right applications:
1. Remove the unit access panels
2. Remove the cooling coil after disassembling bracket coil and plate.
3. Move the condensate drain pan to the right side of the unit chassis.
4. Move the Evap In temperature sensor to holder of the right side.
5. Reinstall the cooling coil.
6. Connect the condensate drains and refrigerant lines. DRY NITROGEN MUST BE FLOWED THROUGH REFRIGERANT LINES
DURING SOLDERING OPERATION.
7. Reinstall unit access panels.
※ I n all horizontal applications in which the unit is installed above a finished ceiling and/or living space, it is recommended
that a secondary drain pan (field supplied) is installed under the entire unit to avoid damage to the ceiling in the event of
condensate overflow.
