Q&A

Q1: What is the cooling and heating capacity?
A: It delivers 13.5 kW cooling and approximately 14.8 kW heating, suitable for large homes or light commercial multi-room setups.

Q2: How many indoor units can it support?
A: It can connect up to 5 indoor units, allowing flexible multi-room climate control from a single outdoor system.

Q3: What type of system is this?
A: It is a multi-split inverter outdoor unit, meaning multiple indoor heads (wall, cassette, or bulkhead) can run independently from one condenser.

Q4: Is it energy efficient?
A: Yes, it uses inverter twin-rotary compressor technology, achieving strong efficiency with COP around ~3.5–4.4 depending on conditions.

Q5: What refrigerant does it use?
A: It uses R410A refrigerant, designed for stable performance and efficient heat exchange.

Maintenance Tips

• Clean outdoor coil every 3–6 months: Remove dust, leaves, and debris to maintain 13.5kW cooling/14.8kW heating performance and prevent compressor strain.
• Keep airflow clearance (minimum ~1m): Ensures proper heat exchange and prevents high-pressure shutdowns in extreme weather operation (-25°C to 50°C range).
• Inspect refrigerant piping annually: Check for leaks, insulation damage, or vibration wear to maintain system efficiency across multi-head operation.
• Check electrical terminals & breaker (32A class): Tighten connections and ensure stable power supply to avoid inverter faults or nuisance tripping.
• Clean drain and base tray: Prevent water buildup, corrosion, and ice formation during heating mode defrost cycles.
• Run seasonal test (cooling + heating): Helps detect early compressor, fan, or sensor issues before peak usage seasons.
• Monitor abnormal noise/vibration: Twin-rotary compressor systems should run smoothly—changes often indicate imbalance or mounting wear.
• Professional servicing yearly: Required for refrigerant handling, pressure checks, and full multi-split system diagnostics.
• Keep anti-corrosion coating intact: Inspect coil protection layer and repaint/repair if exposed in coastal or high-humidity environments.
