Installation Requirements

Unpack and inspect unit for shipping damage. Select appropriate location.

Location: Install on stable, level pad (concrete or composite) with adequate clearance (min 24" on all sides, 48" above).
Electrical Connection: Install dedicated circuit with proper disconnect and fusing per NEC and local codes.
Refrigerant Lines: Connect approved, clean, dehydrated copper lines between outdoor unit and indoor coil.
Condensate Drain: Ensure indoor unit condensate line is properly installed and trapped.
Thermostat Wiring: Connect low-voltage control wires (typically 18-22 AWG) between indoor unit and thermostat.

WARNING! Installation must be performed by a qualified HVAC technician. Improper installation can cause equipment damage, personal injury, or void warranty.

First-Time Startup

After installation is complete, perform system commissioning.

Power Verification: Ensure electrical power is OFF at disconnect. Verify correct voltage at unit terminals.
Refrigerant Charge: Check and adjust refrigerant charge using superheat/subcooling method per manufacturer guidelines.
Thermostat Setup: Configure thermostat for cooling mode, set desired temperature.
System Start: Turn power ON at disconnect. Set thermostat to call for cooling.
Performance Check: Verify proper airflow at indoor registers, check temperature drop across indoor coil (typically 15-20°F), listen for abnormal noises.

CAUTION! Do not operate system without proper refrigerant charge. Ensure all access panels are securely in place before energizing.

Controls and Settings

Primary control is via connected thermostat. Unit has internal protection controls.

Thermostat Functions: Mode (Cool/Off), Fan (Auto/On), Temperature Setpoint, System Switch.

Internal Safeties: High-pressure switch, low-pressure switch, compressor overload, fan cycle control, anti-short cycle timer.

Diagnostic LEDs: Some models feature LED status lights on control board for troubleshooting (refer to wiring diagram).

Factory Settings: Do not adjust internal controls unless qualified. Default settings are optimized for standard operation.

Connecting to Thermostat

Low-voltage connection between indoor air handler/furnace and thermostat controls the outdoor unit.

Turn OFF power to indoor and outdoor units at disconnects.
At indoor unit control board, identify terminals: R (24V power), C (common), Y (compressor), G (fan), O/B (reversing valve for heat pump - if applicable).
Run thermostat cable (minimum 18 AWG, 5-conductor recommended) from indoor unit to thermostat location.
Connect corresponding wires at thermostat sub-base: R to R, C to C, Y to Y, G to G.
Secure connections, restore power, and test operation.

Tip: Use a digital multimeter to verify 24VAC between R and C before connecting thermostat.

Operating Modes

Standard cooling operation. (Note: YCY060G1M is a cooling-only condenser. For heating, a separate furnace or heat pump is required).

Cooling Mode: Set thermostat to COOL, select desired temperature. Compressor and outdoor fan will cycle on to meet setpoint.
Fan Mode: Set thermostat fan to ON for continuous indoor fan operation, or AUTO to cycle with cooling demand.
Off Mode: Set thermostat system switch to OFF. Unit will not operate.
Dehumidification: In cooling mode, system removes humidity from air as a byproduct of cooling.

WARNING! Do not operate system in cooling mode when outdoor temperature is below 55°F without special low-ambient controls, as this can damage the compressor.

Maintenance Procedures

Regular maintenance ensures efficiency, longevity, and reliability. Schedule annual professional maintenance.

Homeowner Tasks:

Keep area around outdoor unit clear of debris, leaves, grass clippings, and snow (min 24" clearance).
Gently clean outdoor coil fins with a soft brush or low-pressure water hose (power OFF). Do not bend fins.
Ensure indoor return air filters are clean. Replace or clean per manufacturer instructions (typically every 1-3 months).

Professional Technician Tasks: Inspect electrical connections, check refrigerant charge, clean coils, check amp draws, verify safety controls, inspect drain line.

Care & Cleaning

Always turn OFF electrical power before cleaning any component.

Outdoor Unit: Use garden hose with gentle spray to wash dirt from coil fins from the inside out. Straighten any bent fins with a fin comb.

Cabinet: Wipe exterior with a damp cloth. Do not use harsh chemicals or pressure washers.

CAUTION! Do not spray water directly onto electrical components, fan motor, or wiring. Do not use steam cleaners.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Unit does not start	Power off, tripped breaker, thermostat setting	Check disconnect and breaker; verify thermostat is set to COOL below room temp.
Unit runs but does not cool	Dirty filter, low refrigerant, dirty coils	Replace air filter; call for professional service to check charge and clean coils.
Unit cycles on/off frequently (short cycles)	Dirty filter, oversized unit, low refrigerant, faulty control	Clean/replace filter; call for professional diagnosis.
Ice on refrigerant lines or coil	Low airflow, low refrigerant	Turn system OFF, check/replace filter, call for service.
Unusual noise (rattling, grinding)	Loose parts, debris in fan, failing motor	Turn power OFF. Check for loose panels or debris. Call for service.
Water leakage at indoor unit	Clogged condensate drain	Clear drain line trap and algae. Use wet/dry vacuum on drain port.

Reset: Turn thermostat to OFF, turn OFF power at disconnect for 5 minutes, restore power, set thermostat to COOL.
