Quantity:1 <br /> shall be leak tested at the factory to ensure the pressure integrity. The evaporator coil and condenser <br /> coil shall be leak tested to 600 psig. The assembled unit shall be leak tested to 465 psig. The <br /> condenser coil shall have a patent pending 1+1+1 hybrid coil designed with slight gaps for ease of <br /> cleaning. A plastic, dual-sloped, removable and reversible condensate drain pan with through-the-base <br /> condensate drain is standard. <br /> High Pressure Control <br /> All units include High Pressure Cutout as standard. <br /> Phase monitor <br /> Phase monitor shall provide 100% protection for motors and compressors against problems caused by <br /> phase loss, phase imbalance, and phase reversal. Phase monitor is equipped with an LED that <br /> provides an ON or FAULT indicator. There are no field adjustments. The module will automatically <br /> reset from a fault condition. <br /> Refrigerant Circuits <br /> Each refrigerant circuit offer thermal expansion valve as standard. Service pressure ports, and <br /> refrigerant line filter driers are factory-installed as standard. An area shall be provided for replacement <br /> suction line driers. <br /> Gas Heating Section <br /> The heating section shall have a progressive tubular heat exchanger design using stainless steel <br /> burners <br /> and corrosion resistant steel throughout. An induced draft combustion blower shall be used to pull the <br /> combustion products through the firing tubes. The heater shall use a direct spark ignition (DSI) system. <br /> On initial call for heat, the combustion blower shall purge the heat exchanger for 20 seconds before <br /> ignition After three unsuccessful ignition attempts, the entire heating system shall be locked out until <br /> manually reset at the thermostat/zone sensor. Units shall be suitable for use with natural gas or <br /> propane (field-installed kit) and also comply with the California requirement for low NOx emissions <br /> (Gas/Electric Only). <br /> Human Interface <br /> The Human Interface shall have a 5 inch color touchscreen display that conforms to FCC Part 15 <br /> Class B with an Ingress Protection Rating of IP24.The display text shall be readable by a person with <br /> 20/20 vision at a distance of 3 feet and 60° angle at lighting levels ranging from 100 lux - 25,000 lux. <br /> Also, the display shall operate at temperatures of -40° C to 70° C. Firmware and unit configurations <br /> shall be able to be restored via a USB storage device. <br /> 2017-09-18 15:17:53Z Page 9 of 9 <br />
