Page 9: Lifting
HE, DE & RE MANUAL LIFTING Engineered Air units are constructed on a structural steel base frame. The unit base frame is equipped with lifting lugs specifically located to facilitate proper lifting of the unit. Spreader bars must be used to keep rigging away from the unit cabinetry.
Page 10: Shipping Materials
HE, DE & RE MANUAL Roof curb mounting – The curbs are constructed of heavy gauge load bearing, galvanized steel, and must be fully insulated after installation. Wood nailer strips are provided for easy attachment of roof flashing. Gasket material is supplied with the unit and must be field mounted on the curb to seal the joint between the curb and the unit frame.
Page 11: Assembly
HE, DE & RE MANUAL ASSEMBLY Warning: Assembly of split units requires bolting together the base frame of adjacent sections. This may require personnel to work under the unit during assembly. Injury or death can result from improper support or improper loading of the curb.
Page 12: Piping, Electrical Or Control Service Connections
HE, DE & RE MANUAL PIPING, ELECTRICAL OR CONTROL SERVICE CONNECTIONS DO NOT install anything that will interfere with equipment access or the rating plate. Engineered Air equipment is constructed with cabinet and floors designed to prevent water from entering the building through the installed unit.
Page 13: Non Recirculating Installation Requirements
HE, DE & RE MANUAL NON RECIRCULATING INSTALLATION REQUIREMENTS For Non Recirculating applications, all air to this unit must be drawn directly from the outdoors. Recirculation of room or building air is not permitted. The outside air intake of the make-up air unit shall be located in accordance with local building code provisions for ventilation air.
Page 14: Field Installed Dampers
HE, DE & RE MANUAL FIELD INSTALLED DAMPERS At times it is desirable to have a damper external to the unit. In some cases the operation of these dampers may cause a “gas trap”, which is a volume of air trapped within the unit between damper sections. In this case a pre-purge cycle shall be used to provide at least four air changes in the ducting before an ignition attempt.
Page 15: De Process Heater Installation Requirements
HE, DE & RE MANUAL DE PROCESS HEATER INSTALLATION REQUIREMENTS 1. DE Series process air heaters require the installation of a manual emergency gas shutoff valve in an appropriate location that allows access to this valve to shut off the fuel to this heater in case of a fire or explosion at the heater or the space served by the heater.
Page 16: Exhaust Fan / Relief Air Provisions
HE, DE & RE MANUAL 7. Refer to the unit function and wiring diagram provided for the lighting interlock of the served space during heater operation in the bake cycle mode. 8. For Non Re-circulating applications, all air to this unit must be drawn directly from the outdoors. EXHAUST FAN / RELIEF AIR PROVISIONS Adequate relief shall be provided so as to prevent building over-pressurization when the ventilation system is operating at its full rated capacity.

Page 18: Duct Mounted Te-6000-Ea3 Temperature Sensor
HE, DE & RE MANUAL DUCT MOUNTED TE-6000-EA3 TEMPERATURE SENSOR Some applications require field installed discharge air sensors. The sensor strip must be parallel to the air flow. The sensor should be mounted near the center of a straight duct 5 to 10 feet (1500 to 3000mm) downstream of the supply air connection to the Engineered Air unit.
Page 19: Drain Traps
HE, DE & RE MANUAL DRAIN TRAPS Each drain connection requires a separate drain trap supplied and installed by the contractor. For a trap to work properly, it must be primed. During freezing periods, primed traps may need to be heat traced or drain and plug the trap when not in use.
Page 20: Heat Transfer Fluids
HE, DE & RE MANUAL HEAT TRANSFER FLUIDS The coil(s) provided have been selected for use with a specific heat transfer fluid as shown on the Submittal Record. Use of other fluids will result in different performance and can damage the coil(s). It is imperative to properly select and apply heat transfer fluids used in heating and cooling systems.
Page 21 HE, DE & RE MANUAL Set thermostat or controller to the “OFF” position and turn unit control switch “ON”. Check the amperage draw of each motor and compressor. Refer to unit or motor rating plate for full load amps. At the unit, check and record the voltage while it is running. For 3 phase power the phase to phase voltage imbalance should be less than 2%.
Page 22: Operation
HE, DE & RE MANUAL OPERATION Warning: This unit is connected to high voltages. Electrical shock or death could occur if instructions are not followed. This equipment contains moving parts that can start unexpectedly. Injury or death could occur if instructions are not followed.
Page 23: Safety Shutoff Valve Leak Test
HE, DE & RE MANUAL SAFETY SHUTOFF VALVE LEAK TEST: Safety shutoff valves require a qualified technician to perform a leak (bubble) test to determine tightness of closure on a least an annual basis. A very small amount of leakage is normal. Valve leakage rates exceeding those noted in the table below require repair or valve replacement.
Page 24: Operational Check
HE, DE & RE MANUAL OPERATIONAL CHECK CALL A QUALIFIED SERVICE PERSON FOR SERVICE. Turn on main and pilot valve up stream of manual firing shut-off valves and check for leaks on unit piping. Check for leaking main and pilot valve seats by closing the manual firing valve and safety shut-off valve.
Page 25: Control Settings
HE, DE & RE MANUAL Do not adjust the main pressure regulator (appliance regulator). The firing rate has been factory set and should not require any adjustment. The air temperature rise should be as listed on the nameplate. If not, the air volume through the unit should be adjusted. This may be accomplished by adjusting the blower speed, by balancing dampers, or both.
Page 26: Maintenance
HE, DE & RE MANUAL MAINTENANCE Warning: This unit is connected to high voltages. Electrical shock or death could occur if instructions are not followed. This equipment contains moving parts that can start unexpectedly. Injury or death could occur if instructions are not followed.
