Heating System - Aluminized steel inshot burners, direct spark ignition, electronic flame sensor, combustion air inducer, redundant automatic single or dual stage gas valve with manual shut-off

Heat Exchanger - Tubular construction, aluminized steel, life cycle tested

Stainless Steel Heat Exchanger is required if mixed air temperature is below 45 Deg F

Electronic Pilot Ignition - Electronic spark igniter provides positive direct ignition of burners on each operating cycle

The system permits main gas valve to stay open only when the burners are proven to be lit

Should a loss of flame occur the gas valve closes, shutting off the gas to the burners Ignition module has LED to indicate status and aid in troubleshooting

Watchguard circuit on module automatically resets ignition controls after one hour of continuous thermostat demand after unit lockout, eliminating nuisance service calls

Ignition control is factory installed in the controls section

Limit Controls - Heat limit controls protect heat exchanger and other components from overheating

Safety Switches - Flame roll-out switch, flame sensor and combustion air inducer proving switch protect system operation

Single Speed Scroll Compressor - Scroll compressors for high performance, reliability and quiet operation

Resiliently mounted on rubber grommets for quiet operation

Compressor Crankcase Heater - Protects against refrigerant migration that can occur during low ambient operation

Thermal Expansion Valve - Assures optimal performance throughout the application range

Removable element head

Filter/Drier - High capacity filter/drier protects the system from dirt and moisture

High Pressure Switch - Protects the compressor from overload conditions such as dirty condenser coils, blocked refrigerant flow or loss of outdoor fan operation

Freezestat - Protects the evaporator coil from damaging ice build-up due to conditions such as low/no air flow or low refrigerant charge

Eco-Last Coil System - Condenser coil features lightweight, all aluminum brazed fin construction

Outdoor Coil Fan Motor - Thermal overload protected, totally enclosed, permanently lubricated sleeve (024, 030, 036 and 048 models) or ball bearings (060, 072, 074 and 090 models), shaft up, wire basket mount

Outdoor Coil Fan - PVC coated fan guard furnished

Construction - Heavy Gauge steel panels and full perimeter heavy gauge galvanized steel base rail provides structural integrity for transportation, handling and installation

Base rails have rigging holes Three sides of the base rail have fork slots

Raised edges around duct and power entry openings in the bottom of the unit provide additional protection against water entering the building

Power/Gas Entry - Electrical and gas lines can be brought through the unit base or through horizontal access knock- outs

Exterior Panels - Constructed of heavy gauge, galvanized steel with a two-layer enamel Painted finish
