Installation Guide
Tools Needed:
- Vacuum pump with gauge manifold
- Refrigerant charging scale
- Tubing cutter and flaring tool
- Torque wrench
- Level
- Drill with hole saw (70-80mm)
- Leak detector
Step-by-Step Installation
- Select Installation Location: Choose a location with proper clearance (min 15cm from ceiling, 30cm from walls) on a solid wall that can support unit weight.
- Install Mounting Plate: Secure the mounting plate to the wall using appropriate anchors and ensure it is perfectly level.
- Drill Wall Hole: Drill a 70mm hole through the wall with a slight downward slope (1cm per meter) for drainage.
- Connect Refrigerant Pipes: Connect indoor and outdoor units with insulated copper pipes using flare connections. Apply leak detection solution to all joints.
- Connect Drainage: Install drain hose with proper downward slope (1:50 minimum) to ensure water drainage.
- Electrical Connection: Connect power cables according to local electrical codes. Ensure proper grounding and use dedicated circuit.
- Vacuum and Charge: Evacuate system to 500 microns for 15 minutes, then charge with specified amount of R410A refrigerant.
- Test Operation: Run system in cooling and heating modes to verify proper operation and check for leaks.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not turning on | Power failure, circuit breaker tripped, remote control batteries dead | Check power supply, reset circuit breaker, replace remote batteries |
| Poor cooling/heating | Dirty filters, blocked airflow, refrigerant leak, outdoor unit obstructed | Clean filters, clear obstructions, check refrigerant charge, clear outdoor unit area |
| Water leaking indoors | Clogged drain pipe, improper installation slope, frozen evaporator | Clean drain pipe, ensure proper slope, check for ice formation |
| Unusual noises | Loose parts, debris in fan, vibration from mounting | Tighten all screws, clear debris from fans, check mounting stability |
| Foul odors | Dirty filters, mold growth in drain pan, stagnant water | Clean filters and drain pan, run fan mode to dry unit |
| Remote not working | Batteries dead, signal blocked, distance too far | Replace batteries, ensure line of sight, stay within 7 meters |
