Installation Guidelines

Unpack and inspect all components. Ensure proper location with adequate clearance.

Position the unit: Place on level pad or mounting brackets with minimum 24-inch clearance on all sides.
Connect refrigerant lines: Use proper brazing techniques and ensure leak-free connections.
Electrical connections: Connect to 240V power supply with appropriate circuit breaker.
Connect thermostat: Wire according to terminal designations (R, C, Y, G, W, etc.).
Connect condensate drain: Route to proper drainage location.

WARNING! Installation must be performed by qualified HVAC technician. Disconnect power before servicing.

Initial Setup & Configuration

After installation, perform initial system setup and testing.

Power on system: Turn on circuit breaker and thermostat.
System check: Verify proper airflow from all vents.
Thermostat programming: Set desired temperature and schedule.
Test modes: Test cooling and heating functions separately.
Check refrigerant charge: Verify proper superheat/subcooling.

CAUTION! Allow system to complete full cycle before adjusting settings.

Tip: Label all wires during installation for future reference.

Maintenance Procedures

Regular maintenance ensures optimal performance and longevity.

Monthly: Check and replace air filter as needed.
Seasonal: Clean outdoor coil with gentle water spray.
Annual: Professional inspection including:
- Check refrigerant charge
- Inspect electrical connections
- Clean evaporator coil
- Check drain line for clogs
- Verify proper airflow
Biannual: Lubricate motor bearings if required.

WARNING! Only qualified technicians should perform refrigerant-related services.

Energy Efficiency Tips

Set thermostat to 78°F in summer, 68°F in winter when home. Use programmable settings for when away. Keep filters clean for proper airflow. Ensure adequate insulation in home. Close curtains during hottest part of day.

Care & Cleaning

Turn off power before cleaning. Clean outdoor coil with garden hose (no high pressure). Keep area around unit clear of debris. Wipe cabinet with damp cloth only.

CAUTION! Do not use harsh chemicals or pressure washers on coils. Keep electrical components dry.

Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
Unit not turning on	Power supply, thermostat, breaker	Check circuit breaker; verify thermostat settings; ensure power switch is on.
Poor cooling performance	Dirty filter, low refrigerant, airflow	Replace filter; check for blocked vents; call technician for refrigerant check.
Unusual noises	Loose parts, debris, motor issues	Turn off unit; check for debris in fan; tighten access panels; call technician.
Ice on coils	Low airflow, low refrigerant	Turn system off; check filter and vents; call technician for refrigerant check.
Water leakage	Clogged drain line, improper slope	Clear drain line; ensure proper drainage slope; check drain pan.
Short cycling	Thermostat location, oversized unit	Relocate thermostat away from heat sources; consult technician for sizing evaluation.

Reset: Turn thermostat to OFF for 5 minutes, then back to COOL or HEAT.
