Cooling:
- Indoor Temperature 27°C(80.6°F) DB/19°C(66.2°F) WB
- Outdoor Temperature 35°C(95°F) DB/24°C(75.2°F) WB
Heating:
- Indoor Temperature 20°C(68°F) DB/15°C(59°F) WB
- Outdoor Temperature 7°C(44.6°F) DB/6°C(42.8°F) WB
Piping Length - Interconnecting Piping Length 7.5m
- Level Difference of Zero
2. Capacities are net capacities
3. EEV : Electronic Expansion Valve
4. Wiring cable size must comply with the applicable local and national code.
