Venter wheel shall be constructed of stainless steel for corrosion resistance. The heat exchanger shall be of the tubular type, constructed of T1-40 aluminized steel for corrosion resistance and allowing minimum mixed air entering temperature of 25°F. Burners shall be of the inshot type, constructed of aluminum coated steel and con- tain air mixture adjustments. All gas piping shall enter the unit cabinet at a single location through either the side or curb, without any field modifications. Integrated control boards shall provide timed control of evaporator fan functioning and burner ignition. Heating section shall be provided with the fol- lowing minimum protection:

a.Primary and auxiliary high-temperature limit switches.

b.Induced draft motor speed sensor.

c.Flame roll out switch (manual reset).

d.Flame proving controls.

e.If any of the above safety devices trip, a LED (light- emitting diode) indicator shall flash a diagnostic code that indicates which safety switch has tripped.

ELECTRIC HEATING SECTION

An electric heating section, with nickel chromium elements, shall be provided in a range of 5 thru 30 KW, offering two stages of capacity - 16 KW and above on 208/230 volt heat- ers and 20 KW and above on 460 and 575 volt heaters. The heating section shall have a primary limit control(s) and auto- matic reset to prevent the heating element system from oper- ating at an excessive temperature. The heating section assembly shall slide out of the unit for easy maintenance and service. Units with Electric Heating shall be wired for a single point power supply with branch circuit fusing (where required).

UNIT OPERATING CHARACTERISTICS

a.Unit shall be capable of starting and running at 125°F outdoor temperature, exceeding maximum load criteria of ARI Standard 210/240.

b.The compressor, with standard controls, shall be capable of operation down to 0°F outdoor tempera- ture.

c.Unit shall be provided with fan time delay to prevent cold air delivery before heat exchanger warms up (Gas heat only).

ELECTRICAL REQUIREMENTS

All unit power wiring shall enter unit cabinet at a single factory provided location and be capable of side or bottom entry, to minimize roof penetrations and avoid unit field modifications. Separate side and bottom openings shall be provided for the control wiring.
