Features at a Glance

Key components: Compressor, Spine Fin™ coil, WeatherGuard™ top, Sound-reducing fan, Service valves, Electrical connections.

Installation

Unpack and inspect contents. Place on level, stable pad.

1. Select Location: Ensure adequate clearance (24" minimum on all sides, 48" above).
2. Set Pad: Use level concrete pad or approved composite pad.
3. Connect Refrigerant Lines: Braze lines to service valves using nitrogen purge.
4. Connect Electrical: Run line voltage (240V) and low-voltage thermostat wires to connection box.
5. Evacuate and Charge: Evacuate system to 500 microns, charge per nameplate data.

WARNING! Installation must be performed by a qualified HVAC technician. Follow all local codes and refrigerant handling regulations. Unit contains high voltage and pressurized refrigerant.

First-Time Setup & Startup

After installation, perform initial startup and system check.

1. Verify Electrical: Ensure power is disconnected. Check all wiring connections are tight.
2. Check Refrigerant Charge: Use manifold gauges to verify correct subcooling per outdoor temp.
3. Power On: Restore power to indoor and outdoor units.
4. Set Thermostat: Set to COOL mode, temperature below room temp to initiate cooling cycle.
5. System Check: Listen for normal operation. Check for proper airflow at registers.
6. Measure Performance: Check temperature drop across evaporator coil (typically 15-20°F).

CAUTION! Do not operate without proper refrigerant charge. Ensure fan is free to rotate before applying power.

Controls and Settings

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

Internal Controls: High-pressure switch, Low-pressure switch, Compressor overload, Time-delay relay (typically 5 minutes), Fan cycle control (on some models).

Thermostat Settings: COOL, OFF, FAN AUTO/ON. For optimal efficiency, set temperature to 78°F when occupied.

Dip Switches (if present): May be used to configure fan delay or other options. Refer to installation manual for specific settings.

Connecting to System Components

This outdoor unit must be connected to a matching indoor coil and air handler/furnace.

1. Indoor Unit: Match capacity and refrigerant type. Ensure coil is rated for R-410A.
2. Refrigerant Lines: Use clean, dehydrated copper tubing of correct size.
3. Thermostat: Connect low-voltage wires (R, C, Y, G, O/B if heat pump) to control board.
4. Condensate Drain: Ensure indoor unit drain line is properly installed and trapped.

Tip: Always use a nitrogen purge when brazing to prevent oxidation inside lines.

Operation

Normal cooling cycle operation.

1. Thermostat Call: When room temp rises above set point, thermostat sends signal to outdoor unit.
2. Compressor Start: After time delay, compressor and condenser fan energize.
3. Cooling Mode: Refrigerant circulates, absorbing heat indoors and rejecting it outdoors.
4. Cycle Off: When set point is reached, thermostat signal stops, unit shuts off.
5. Fan Operation: Indoor blower may continue to run for a short period (if fan delay is enabled) to utilize remaining cooling capacity.

WARNING! Do not attempt to operate unit if unusual noises, vibrations, or odors are present. Turn off power and contact a qualified technician.

Maintenance Procedures

Regular maintenance ensures efficiency and longevity. Perform at least annually, preferably before cooling season.

1. Power Off: Disconnect electrical power at disconnect switch.
2. Clean Coil: Remove debris from fins. Use a fin comb to straighten bent fins.
3. Clean Area: Keep area around unit clear of vegetation and debris (minimum 24").
4. Check Electrical: Inspect wiring for damage or corrosion. Tighten connections.
5. Check Refrigerant Lines: Inspect for insulation damage or leaks.
6. Check Mounting: Ensure unit is level and stable on pad.
7. Professional Service: Have a technician check refrigerant charge, amp draw, and system pressures annually.

Care & Cleaning

Disconnect power before any cleaning. Use a garden hose to gently spray debris from the coil fins from the inside out. Do not use a pressure washer.

CAUTION! Do not use chemical cleaners on the coil unless specified by American Standard. Keep electrical components dry.
