Outdoor Unit Installation Clearance Requirements
Proper installation requires specific clearances around the outdoor unit to ensure adequate airflow and efficient operation. The following clearances are recommended:
- Front and sides: 20 inches (500mm) or more if clear.
- Sides/Rear: 20 inches (500mm) or more if any two sides (left, right, rear) are clear.
- Front/Sides: 4 inches (100mm) or more.
- Rear: 14 inches (350mm) or more.
Note:
The unit meets all spatial requirements shown in the Installation Clearance Requirements above.
Indoor Unit Fan Performance
This section describes the fan performance characteristics of the indoor unit, illustrating the relationship between external static pressure and airflow rate at various speed settings.
- The graph displays Airflow Rate (CFM) on the Y-axis against External Static Pressure (in.w.c.) on the X-axis.
- The X-axis ranges from 0 to 0.8 in.w.c.
- The Y-axis ranges from 0 to 1400 CFM.
- The graph shows multiple lines representing different fan speed settings: SH (Super High), H (High), M (Medium), and L (Low).
- As external static pressure increases, the airflow rate generally decreases across all speed settings. The 'SH' setting provides the highest airflow, followed by 'H', 'M', and 'L'.
Key Features
- Multi-position installation: horizontal (left or right), vertical (up or down).
- Aluminum Coil.
- Constantly Air Flow system up to 0.80 In.W.G.
- 1 inch R4.2 fiberglass free insulation reduces condensation and boosts efficiency (optional).
- Optional Auxiliary heat kit up to 25kW.
- Easy Maintenance.
- Multiple control options available:
- Two-way communication wired controller with built-in WiFi: AWC-8P-LC-WIFI.
- Wireless remote controller.
- Third-Party 24V Thermostat.
- Adaptive Control System.
- High efficiency up to 19 SEER2, 12.5 EER2, 10.3 HSPF2.
- 100% heat output at -4°F*.
- Chassis heater and crankcase heater equipped as standard.
*For 36K model, rated cooling capacity/heating capacity at -4°F = 100%
