Electrical Schematic and Wiring Overview
The G+ ITWG 022 R5 follows a standard control logic for split systems. For field technicians, understanding the terminal block configuration is essential for safe integration with the outdoor condenser.
- Terminal L (Brown): Main Power Phase.
- Terminal N (Blue): Neutral Return.
- Terminal S (Signal/Communication): Data line between indoor and outdoor units (vital for compressor cycling).
- Terminal E (Yellow/Green): Earth Grounding.
Engineering Note: Ensure that the communication cable is shielded or properly separated from high-voltage lines to prevent electromagnetic interference (EMI), which can lead to sensor errors or erratic fan speeds.
Engineering Advice and Installation Notices
- Mounting Height: For optimal airflow and thermal stratification, the indoor unit must be installed at a minimum height of 2.3 meters from the floor. This ensures that the cold air plume has sufficient distance to mix with room air before reaching occupants.
- IPX4 Compliance: The IPX4 rating indicates protection against water splashes from any direction. However, this unit is strictly for indoor use. Avoid installation in high-humidity zones like laundry rooms without adequate ventilation.
- Condensate Management: Given the 6.30 KW cooling capacity, significant condensation will occur. Ensure the drain pipe has a minimum downward slope of 1:50 to prevent water backup and microbial growth in the pan.
- Air Filter Maintenance: The G+ series often includes high-density filters. These should be inspected every 15 days in dusty environments to maintain the rated 21,500 BTU/Hr efficiency.
Benefits of the G+ ITWG 022 R5 Model
- Optimized Airflow: The “G+” design features wider air vanes, allowing for a longer “throw” of air, which is essential for rectangular rooms.
- Tropicalized Design: Specifically engineered to handle the high head pressures associated with Egyptian and Gulf climates.
- Serviceability: As a widely distributed model, spare parts such as fan motors and PCB controllers are readily available throughout the region.

When evaluating the power of an air conditioning unit like the Unionaire G+ ITWG 022 R5, technicians and engineers often look for the “Horsepower” (HP) rating to determine suitability for specific room volumes. Based on the technical data plate indicating a cooling capacity of 21,500 BTU/Hr (6.30 KW), this unit is officially categorized as a 2.5 HP model.
The Engineering Logic: BTU to HP Conversion
In the HVAC industry, particularly within the Middle Eastern and African markets where Unionaire is a dominant brand, horsepower is a nominal term used to simplify capacity. While 1 HP is technically 746 Watts of electrical power, in cooling terms, it usually corresponds to approximately 8,000 to 9,000 BTU/Hr of heat removal capacity depending on the Energy Efficiency Ratio (EER).
Horsepower Classification Table
| Nominal HP | BTU/Hr Range | KW Cooling Capacity | Model Reference |
| 1.5 HP | 12,000 – 13,000 | 3.51 – 3.81 | ITWG 012 / 013 |
| 2.25 HP | 18,000 – 19,000 | 5.27 – 5.56 | ITWG 018 / 019 |
| 2.5 HP | 21,000 – 22,000 | 6.15 – 6.45 | G+ ITWG 022 R5 |
| 3.0 HP | 24,000 – 26,000 | 7.03 – 7.62 | ITWG 024 / 025 |
Technical Value Comparison: G+ ITWG 022 R5 vs. Standard 3 HP Units
The G+ ITWG 022 R5 provides a unique middle ground. While many manufacturers jump from 18,000 BTU (2.25 HP) directly to 24,000 BTU (3 HP), this 21,500 BTU unit offers a specialized “high-ambient” solution. It provides more “muscle” than a standard 2.25 HP unit without the higher electrical draw of a full 3 HP system.
| Metric | Unionaire 2.25 HP | Unionaire G+ 2.5 HP | Competitor 3 HP |
| Cooling (BTU) | 18,000 | 21,500 | 24,000 |
| Cooling (KW) | 5.27 | 6.30 | 7.03 |
| Weight (Indoor) | 11.0 Kg | 12.5 Kg | 14.5 Kg |
| Voltage | 220-240V | 220-240V | 220-240V |
Electrical and Mechanical Characteristics
The G+ ITWG 022 R5 is engineered for durability. The “R5” suffix typically indicates a specific revision of the refrigerant cycle or control board logic, optimized for the R410A or R22 gas types (refer to the outdoor unit label for gas type confirmation).
- Cooling Power: 6.30 KW allows for rapid temperature pull-down in rooms up to 30 square meters.
- Mass: At 12.5 Kg, the internal heat exchanger (evaporator) is dense, featuring high-grade copper tubing and hydrophilic aluminum fins to prevent “ice-up” during long operation cycles.
- Protection: The IPX4 rating ensures that the internal electronics are shielded from moisture ingress, which is critical during the dehumidification process.
Installation Notice and Engineering Tips
- Circuit Breaker Selection: For a 2.5 HP (21,500 BTU) unit, a dedicated 20A or 25A C-Type circuit breaker is recommended to handle the inductive start-up current of the compressor.
- Piping Diameter: This capacity usually requires a 1/2″ (12.7mm) suction line and a 1/4″ (6.35mm) liquid line. Using undersized piping will significantly reduce the 6.30 KW cooling output.
- Placement: Due to the high airflow velocity of a 2.5 HP unit, avoid placing it directly facing seating areas to prevent “cold draft” discomfort.
- Vacuuming: Always perform a deep vacuum (below 500 microns) during installation to ensure the 21,500 BTU efficiency is met and to protect the compressor from non-condensables.
Professional Benefits of the 2.5 HP G+ Series
- Balanced Load: Ideal for “L-shaped” living rooms where a 1.5 HP unit is too weak and a 3 HP unit cycles too frequently (short-cycling).
- Egyptian Engineering: Built to withstand the T3 climate conditions (up to 52°C ambient temperatures).
- Quiet Operation: Despite the high BTU output, the G+ series uses an oversized tangential fan to move air at lower RPMs, reducing decibel levels.
