American Standard HVAC YCC036F-L Manual

The American Standard YCC036F-L is a high-efficiency, single-stage, 3-ton residential condensing unit designed for outdoor installation. It features a scroll compressor, durable weather-resistant cabinet, and compatibility with American Standard indoor units for optimal system performance. Below are key sections for safety, features, installation, setup, operation, and troubleshooting.

Features at a Glance

Key components: Weather-resistant galvanized steel cabinet, Scroll compressor, Single-stage operation, High-efficiency coil, Liquid and suction line service valves, Low-pressure switch, High-pressure switch.

Installation

Unpack and inspect unit for shipping damage. Select a suitable outdoor location.

1. Location: Place on a level, stable pad (concrete or composite) with adequate clearance for airflow and service.
2. Electrical Connection: Disconnect all power. Run properly sized copper wiring from disconnect to unit terminal block per local codes.
3. Refrigerant Lines: Connect pre-charged, insulated lineset from indoor unit to outdoor service valves. Brazing must be done with nitrogen purge.
4. Condensate Drain: Ensure indoor unit condensate line is properly installed and routed.
5. Final Check: Verify all electrical connections are tight, lineset is insulated and secured, and unit is level.

WARNING! Installation must be performed by a qualified HVAC technician. Incorrect installation can cause property damage, personal injury, or death. Handle refrigerant according to EPA regulations.

First-Time Setup

After installation, perform initial startup and system check.

1. Power On: Restore power at disconnect and indoor air handler/furnace.
2. Thermostat Setup: Set thermostat to OFF mode. Configure cooling setpoint, fan mode (AUTO recommended).
3. System Start: Set thermostat to COOL mode and a temperature below room temp. Unit should start after a short delay.
4. Performance Check: Verify adequate airflow from indoor vents, listen for normal operating sounds, check for unusual vibrations.
5. Measurements: Technician should verify correct refrigerant charge via subcooling method, electrical amp draw, and temperature split across indoor coil.

CAUTION! Do not operate without proper refrigerant charge. Allow unit to complete a full cycle before adjustments.

Specifications

• Cooling Capacity: 36,000 BTU/h (3 Tons).
• SEER Rating: Up to 16 SEER (depending on matched indoor unit).
• Refrigerant Type & Charge: R-410A, factory pre-charged for 15 ft lineset.
• Electrical: 208/230V, 1 Phase, 60 Hz. Minimum Circuit Ampacity: 19.0. Max Fuse/Breaker: 25 A.

Controls and Settings

Primary control is via the indoor thermostat. Unit has internal safety and operational controls.

Thermostat: Controls mode (COOL, OFF, FAN), temperature setpoint, and fan operation (AUTO, ON).

Unit Internal Controls: Low-pressure switch (opens on low refrigerant pressure), High-pressure switch (opens on excessive pressure), Compressor contactor, Fan relay, Compressor overload protection.

No user-adjustable settings on outdoor unit. All system adjustments (charge, airflow) must be made by a qualified technician.

Connecting Components

Connects to indoor coil/air handler and thermostat.

1. Indoor Unit: Matched American Standard evaporator coil or air handler. Connected via refrigerant lineset and low-voltage control wire.
2. Thermostat: Low-voltage (24V) connection (R, C, Y, G terminals) to control cooling and fan.
3. Power Supply: Dedicated 230V circuit with disconnect within sight of unit.
4. Condensate Drain: From indoor unit to suitable drain.

Tip: Use a properly sized lineset. Excessive length or improper sizing reduces efficiency and capacity.

Operation

Normal operation is automatic via thermostat.

1. Cooling Cycle: When thermostat calls for cooling, it energizes the Y and G terminals. Outdoor fan and compressor start. Indoor blower starts.
2. Cycle Completion: When set temperature is reached, thermostat de-energizes Y and G. Compressor and outdoor fan stop. Indoor blower may run briefly to utilize remaining coil cooling.
3. Fan Mode: Setting thermostat fan to ON runs indoor blower continuously for air circulation without cooling.
4. Off Mode: Thermostat set to OFF prevents cooling cycle.

WARNING! Do not switch thermostat between HEAT and COOL modes rapidly. Allow 5 minutes between mode changes to prevent compressor damage.

Maintenance

Regular maintenance ensures efficiency and longevity. Disconnect all power before servicing.

1. Outdoor Coil: Keep clean and free of debris (leaves, grass, dirt). Gently clean with a soft brush or low-pressure water hose (power off).
2. Airflow: Maintain at least 24 inches clearance on all sides, especially around the coil.
3. Inspect: Periodically check for loose fasteners, damaged insulation on refrigerant lines, or signs of refrigerant leaks.
4. Professional Service: Schedule annual maintenance by a qualified technician to check refrigerant charge, electrical components, and system performance.

CAUTION! Do not use a pressure washer or harsh chemicals on the coil fins. Do not attempt to repair refrigerant system.

Regulatory Information
