Installation Guidelines

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

  1. Site Selection: Place on a stable, level pad away from obstructions, with adequate clearance for airflow and service.
  2. Mounting: Secure the condenser unit to a concrete pad or approved mounting system.
  3. Line Set Connection: Connect pre-charged or field-installed refrigerant lines using proper brazing techniques and nitrogen purge.
  4. Electrical Connection: Run power and control wiring from the disconnect and indoor unit per the wiring diagram.
  5. Condensate Drain: Ensure proper drainage from the indoor coil is installed and trapped.

WARNING! Installation must be performed by a qualified HVAC technician in accordance with all local codes and the National Electrical Code (NEC). Disconnect all power before servicing.

First-Time Startup & Commissioning

After installation, perform a complete system checkout before releasing to the homeowner.

  1. Pre-Start Check: Verify all electrical connections are tight, refrigerant lines are secure, and the filter is clean.
  2. Power On: Energize the indoor and outdoor units at the disconnect.
  3. Thermostat Setup: Configure the thermostat for cooling mode and set the desired temperature.
  4. System Start: Initiate a cooling cycle. Listen for abnormal noises.
  5. Measurements: Check superheat/subcooling, measure voltage/amperage, and verify temperature drop across the indoor coil.
  6. Airflow: Ensure correct CFM is delivered by the indoor blower.

CAUTION! Do not operate the system without the correct refrigerant charge or with blocked airflow. This can cause severe compressor damage.

Technical Specifications

System Controls & Operation

The system is controlled by a standard 24V thermostat. Advanced communicating controls may be used for enhanced efficiency.

Basic Thermostat Operation: Set to COOL mode, select fan (AUTO or ON), and set temperature. The system will cycle automatically.

LED Diagnostics: The control board features an LED that flashes a code to indicate normal operation or specific fault conditions. Refer to the fault code chart on the inside of the access panel.

Safety Lockouts: The system includes automatic lockouts for conditions like low voltage, high pressure, or compressor overload. A power cycle may be required to reset after the fault is corrected.

Electrical Connections

Refer to the wiring diagram located on the inside of the outdoor unit's service panel.

  1. Connect line voltage (L1, L2) from the fused disconnect to the contactor.
  2. Connect the 24V control wiring (R, C, Y, O/B, G, etc.) from the thermostat and indoor unit to the low-voltage terminal strip.
  3. Ensure the ground wire is securely connected.
  4. Verify correct voltage at the unit before applying power.

Tip: Use copper conductors only. Ensure all connections are tight to prevent voltage drop and overheating.

Refrigerant Charging Procedure

This unit uses R-410A. Charge must be adjusted based on actual line set length.

  1. Recovery/Evacuation: Recover any existing refrigerant. Evacuate the system to a deep vacuum (below 500 microns) to remove moisture and non-condensables.
  2. Weigh-In Charge: For pre-charged units with a standard line set, release the factory charge. For longer lines, add additional refrigerant. Charge by weight according to the calculation chart provided.
  3. Superheat/Subcooling Method: For final adjustment in cooling mode, measure and adjust to the target subcooling specified in the service facts (typically 10°F ± 3°F).
  4. Leak Check: After charging, perform a thorough leak check with an electronic leak detector.

WARNING! R-410A operates at much higher pressures than R-22. Use dedicated gauges, hoses, and recovery equipment rated for R-410A. Always wear safety glasses and gloves.

Maintenance Schedule

Regular maintenance is essential for efficiency, longevity, and warranty compliance.

TaskFrequencyNotes
Replace/clean air filterMonthly (or as needed)Restricted airflow is a leading cause of failure.
Clean outdoor coilAnnually (Spring)Gently wash with water from the inside out. Do not use high pressure.
Inspect electrical connectionsAnnuallyCheck for tightness and signs of overheating.
Clear condensate drainAnnuallyPour a cup of diluted bleach or vinegar to prevent algae.
Check refrigerant chargeAs needed/if performance dropsVerify subcooling/superheat.
Inspect fan motor & bladesAnnuallyCheck for wear, balance, and clean blades.

Care & Cleaning

Outdoor Unit: Keep the area around the condenser clear of leaves, grass, shrubs, and debris (at least 2 feet clearance). Clean the coil annually with a garden hose.

Indoor Unit: Ensure the filter is clean. Keep supply and return vents unobstructed.

CAUTION! Never use a pressure washer on the aluminum fins. Do not attempt to clean the interior electrical components. Always turn off power at the disconnect before performing any cleaning near the unit.

Troubleshooting Guide

SymptomPossible CauseCorrective Action
Unit will not startPower off, blown fuse/breaker, thermostat setting, safety lockoutCheck disconnect and breakers. Verify thermostat is in COOL mode below room temp. Reset power.
Unit runs but does not coolDirty filter/coil, low refrigerant, faulty compressorCheck/clean filter and outdoor coil. Check refrigerant charge and compressor operation.
Unit cycles on/off frequently (short cycles)Dirty filter/coil, overcharge/undercharge, oversized unitCheck airflow and refrigerant charge. Verify unit size is correct for the home.
Ice on refrigerant lines or indoor coilLow airflow (dirty filter/coil, bad blower), low refrigerant chargeTurn system off. Check filter and indoor coil cleanliness. Check blower operation. After thaw, check charge.
Unusual noiseLoose parts, debris in fan, failing motor or compressorTurn off power. Inspect for loose panels, screws. Clear debris from fan. Listen for bearing noise.
Water leakage indoorsClogged condensate drain, disconnected drain lineClear the condensate drain line and trap. Ensure drain pan is not cracked.

LED Fault Codes: Count the number of flashes from the LED on the control board. Refer to the code chart on the panel for specific diagnostics (e.g., 1 flash = Low Pressure Lockout, 2 flashes = High Pressure Lockout).
