Ground Level Installation Ground level platform requirements: FIGURE 2 Blockoff Plate (Return Air Compartment) - The unit MUST be situated to provide safe access for servicing. Platform may be made of either concrete or pressure treated wood and MUST be level and strong enough to support unit weight. Position platform separate from building foundation. Install in well-drained area, with top surface of platform above grade level.
