Table 2 — A (min)
For R454B refrigerant charge amount and minimum room area:
The indoor unit should be installed at least 5.9ft/1.8m above the floor, and the minimum room area for operation or storage should be as
specified in Table 2.
NOTE: For units installed in the conditioned space, users may need to adjust temperatures compensations for sensed space temperature.
Configuration found in IR remote manual for parameter setting.

Amin ( ft2 (m2)
Mc - Actual refrigerant charge in the system lbs (Kg)
Mrel - Refrigerant releasable charge lbs (kg)
Ho - Release height, measured from duct opening, in ft (m)
Hinst - Height of install, from the bottom of the indoor appliance, measured in ft (m)
Ho ≈ Hinst
Warning: Minimum room area of conditioned space is based on releasable charge or total system refrigerant charge.
