Capacity Tables EDUS181520C
62 Multi-Split Type Air Conditioners RMXS-L Series
Notes: 1. These figures illustrate the rate of change in capacity of a standard indoor unit system at maximum load
(with the thermostat set to maximum) under standard conditions.
Moreover, under partial load conditions there is only a minor deviation from the rate of change in capacity
shown in the above figures.
2. With this outdoor unit, evaporating pressure constant control when cooling, and condensing pressure
constant control when heating is carried out.
