Summary

Important Safety Instructions

Shipping Inspection

Parts

Inspect unit for all required components; report missing items to Goodman or distributor.

Codes & Regulations

Replacement Parts

Pre-Installation Considerations

Preparation

Ensure all steps are understood, gather tools and supplies before installation.

System Matches

System must be manufacturer approved and AHRI listed; unmatched systems void warranty.

Interconnecting Tubing

Minimize tubing length, allow for coil removal for service.

Clearances

Maintain minimum service clearance; elevate unit if in wet areas.

Horizontal Applications

Secondary drain pan required if above living space; route to visible location.

Installation Location

Upflow Installation

No field modifications mandatory; remove drip shield for efficiency.

Horizontal Left Installation

No field modifications; primary drain at bottom right, secondary at bottom left.

Downflow;Horizontal Right Installation

Downflow kit (DFK) required for downflow; prevents coil pan sweating.

Refrigerant Lines

Tubing Size

Follow condenser/heat pump specifications for correct tubing size.

Tubing Preparation

Ensure cut ends are round, burr-free, and clean to prevent leaks.

Tubing Connections for TXV Models

TXV models come with factory-installed TXV with bulb on vapor tube.

Condensate Drain Lines

Ductwork

Return Ductwork

Connect return ductwork to the air handler bottom in upflow configuration.

Return Air Filters

Electric Heat

No Electric Heat Installed

Install cover plate over electric heat opening if no kit is installed.

Electrical and Control Wiring

Building Electrical Service Inspection

Unit designed for single-phase; verify supply voltage agrees with nameplate.

Wire Sizing

Use copper conductors, check MCA on rating plate, ensure 2% voltage drop.

Maximum Overcurrent Protection (MOP)

Install NEC/CEC approved overcurrent device; size larger than MCA but not exceeding MOP.

Electrical Connections - Supply Voltage

Use copper conductors, utilize knockouts, ensure proper strain relief.

Low Voltage Connections

Connect 24V control voltage to thermostat and condenser; use 18AWG or 16AWG wire.

Achieving 2% Low Leakage Rate

Start-Up Procedure

Regular Maintenance

24 Volt Thermostat Wiring

AVPTC Motor Orientation
