WARNING
▶ Regulation for refrigerant leakage
: the amount of refrigerant leakage should satisfy the following equation for human safety.
p If the above equation can not be satisfied, then follow the following steps.
- Selection of air conditioning system: select one of the next
1. Installation of effective opening part
2. Reconfirmation of Outdoor Unit capacity and piping length
3. Reduction of the amount of refrigerant
4. Installation of 2 or more security device (alarm for gas leakage)
- Change Indoor Unit type
: installation position should be over 2m(6.6ft) from the floor (Wall mounted type ’ Cassette type)
- Adoption of ventilation system
: choose ordinary ventilation system or building ventilation system
- Limitation in piping work
: Prepare for earthquake and thermal stress
WARNING
▶
Refer to model information since the CF Value of correction factor differs depending on model.
Total amount of refrigerant in the system
≤ 0.44 (kg / m
3
)(0. 028(lb/ft
3
))
Volume of the room at which Indoor Unit of the least capacity is installed
