Total refrigerant quantity for 10HP = refrigerant replenishment quantity upon shipment
(11kg) + additional refrigerant replenishment corresponding to the pipe length.

Calculate out the indoor volume [B (m
3
)] (according to the minimum volume)

Calculate out the refrigerant density:
[A (kg)] / [B (m
3
)]
≤ Density threshold: 0.3kg/m
3

Measures against crossing of the refrigerant density threshold.

In order to keep the refrigerant density below the threshold value, please install a
mechanic ventilation device. (Perform ventilation often.)

In case frequent ventilation is impossible, please install the leakage detection alarm
device linked with the mechanical ventilation device.
