Installation Guide
Tools Needed:
- Vacuum pump with gauge manifold
- Flaring tool set
- Tubing cutter
- Torque wrench
- Multimeter
- Level
- Drill with hole saw attachment
- Refrigerant scale
Step-by-Step Installation
- Select Installation Location: Choose appropriate locations for indoor and outdoor units considering airflow, drainage, and structural support.
- Mount Indoor Unit Bracket: Securely mount the wall bracket using appropriate anchors for wall type, ensuring it is perfectly level.
- Create Wall Penetration: Drill a 3-inch hole through the exterior wall with a slight downward slope for drainage.
- Install Refrigerant Lines: Connect copper refrigerant lines between indoor and outdoor units, ensuring proper insulation on suction line.
- Connect Electrical Wiring: Run electrical wiring from outdoor unit to indoor unit following local electrical codes and manufacturer specifications.
- Connect Drain Line: Install condensate drain line with proper slope and route to appropriate drainage location.
- Vacuum and Charge System: Evacuate the system to 500 microns, hold for 15 minutes, then charge with specified refrigerant amount.
- Test System Operation: Test cooling and heating modes, check temperature differentials, and verify proper drainage.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not turning on | Power outage, tripped breaker, remote control issues | Check power supply, reset breaker, replace remote batteries |
| Poor cooling/heating | Dirty filters, low refrigerant, blocked airflow | Clean filters, check refrigerant charge, clear obstructions |
| Water leakage | Clogged drain line, improper installation slope | Clear drain line, ensure proper drainage slope |
| Unusual noises | Loose parts, debris in fan, vibration | Tighten mounting, clear debris, check isolation |
| Ice formation | Low refrigerant, dirty filters, faulty defrost | Check charge, clean filters, verify defrost operation |
| Remote not working | Dead batteries, signal obstruction, sensor issues | Replace batteries, clear line of sight, check sensor |
