Notes:-
1. Capacities are based on the following conditions:
Cooling
• Indoor temp.: 80°FDB or 67°FWB/ outdoor temp.: 95°FDB/Equivalent piping length: 25 ft, level difference: 0.
Heating
• Indoor temp.: 70°FDB/ outdoor temp.: 47°FDB or 43°FWB/Equivalent piping length: 25 ft, level difference: 0.
2. Capacities are Net Capacities
3. Due to our policy of innovation some specifications may be changed without prior notification
4. To be added for more available Models
5. EEV : Electronic Expansion Valve
6. Sound measured at 1m(3.3ft) away from the center of the unit.
The values depends on the ambient conditions and values are normally higher in actual operation.
