Mounting Procedures
Step-by-step mounting instructions for indoor and outdoor units.
- Indoor Unit: Mount on solid wall using template, ensure level installation
- Outdoor Unit: Place on stable pad or mounting brackets, allow vibration isolation
- Drill wall hole with 5° downward slope toward outdoor side
- Install wall sleeve and sealing grommet
- Secure all mounting hardware according to torque specifications
CAUTION! Ensure proper drainage slope for condensate removal.
Refrigerant Piping
Refrigerant line set installation and connection procedures.
- Measure and cut piping to required length
- Flare pipe ends using proper flaring tool
- Install insulation on both liquid and suction lines
- Connect piping to indoor and outdoor units
- Torque connections to manufacturer specifications
Tip: Keep piping runs as short and straight as possible for optimal performance.
Electrical Connections
Wiring and electrical connection guidelines.
| Connection | Specification |
|---|
| Power Supply | 208/230V ±10%, 1-phase, 60Hz |
| Circuit Breaker | Dedicated branch circuit required |
| Wire Size | Minimum 12 AWG for most models |
| Communication Wiring | Use shielded cable for control connections |
| Grounding | Proper equipment grounding mandatory |
Vacuum Drying
Evacuation and dehydration procedures.
- Connect vacuum pump to service ports
- Evacuate system to 500 microns or less
- Hold vacuum for 15 minutes to check for leaks
- If vacuum rises above 1000 microns, check for leaks
- Charge system with specified refrigerant amount
WARNING! Never release refrigerant to atmosphere - EPA violation.
System Commissioning
Final setup and performance verification.
- Power on system and check for error codes
- Verify proper airflow and temperature differential
- Check refrigerant pressures and superheat/subcooling
- Test all operating modes (cooling, heating, fan)
- Program remote control and test functions

- Verify electrical connections annually
- Professional service recommended every 2 years
CAUTION! Always disconnect power before performing maintenance.
Troubleshooting
| Symptom | Possible Cause | Corrective Action |
|---|
| Unit not starting | Power supply, circuit breaker | Check power, reset breaker, verify voltage |
| Poor cooling/heating | Dirty filters, low refrigerant | Clean filters, check refrigerant charge |
| Water leakage | Clogged drain line | Clear condensate drain line |
| Unusual noise | Loose parts, fan issues | Tighten mounting, check fan assembly |
| Error codes displayed | Sensor failure, system fault | Refer to service manual for specific codes |
