Horizontal Airflow Units
All ceiling mounted gPod units have horizontal airflow configuration. Field supplied, and installed ductwork is
intended to be connected to the factory provided duct collars on the supply and return air openings.
Ceiling units are shipped with a drive packages pre-set at the
factory to overcome approximately 0.5” WC external
static pressure. But the blower speed may need to be re-adjusted in the field for actual site and space conditions.
There are various options to allow mounting of ceiling units. These must be pre-determined by the Design Engineer
based on site conditions and available installation options. One method is to hang the ceiling mounted units by
means of a cradle type installation. This method requires four (4) field supplied threaded hanging support rods
which must be securely attached to the building structure and two (2) field provided lower support channels
connected to the pairs of threaded hanging support rods. An appropriate lifting device must be used to raise the
evaporator section into place before attaching to the mounting system. Use caution and appropriate safety
methods when making such a lift. Attaching hardware such as washers, nuts and jam nuts are also field supplied to
secure the mounting system to each threaded rod. Tighten the nuts so the weight is supported evenly by the four
rods and the unit is level or slightly pitched towards the location of condensate drain.
