Refer to the controller information, thermostat information, and your unit’s wiring diagram as necessary to assist in completing the following procedures. Complete the Warranty Registration and Start-Up form provided with the unit or via PDF.

1. Record the Job Number, Serial Number, and Model Number on the start-up sheet. These items may be found on the unit nameplate. Record rated amp draws for all components.
2. After completing the Start-up checks, ensure that all tools, meters, and other items are cleared from the unit’s case. Place refrigerant gauges on the compressor(s), if applicable, and replace any access panels that do not need to be open for these checks.
3. Move the disconnect switch to the ON position.
4. Measure and record the main power and control power voltage readings on the start-up sheet. Verify that they match the system rating. Record the space and ambient temperatures.
5. Enable the system for operation per the applicable control operation.
6. Verify that the fan is operating. Airflow should be felt at the unit outlet or the nearest air device. Use an amp meter to measure the amp draw of the blower motor and record on the start-up sheet.
7. Verify cooling operation. Offset sensor readings or set points as necessary to create a call for cooling. Allow the system to run and record the supply air temperature. Record the compressor amp draw, pressures, and temperatures, condenser fan amp draw, and chilled water or condenser water temperature as applicable.
8. Verify heating operation. Offset sensor readings or set points as necessary to create a call for heating. Allow the system to run and record the supply air temperature. Record the compressor amp draw pressures, and temperatures, hot water or steam temperatures, and electric heater amp draw as applicable. Note that heat pump operation may be inadvisable during high ambient conditions and result in high pressure alarms.
9. Verify dehumidification operation (if applicable). Offset sensor readings or set points as necessary to create a call for dehumidification. Verify hot gas reheat operation (if applicable).
10. Verify humidifier operation (if applicable). Offset sensor readings or set points as necessary to create a call for humidification. Verify humidifier toggle switch is in its ON position. Verify that the humidifier is activate (cylinder should be warm). Apply an amp meter to the humidifier circuit and record the amp draws on the start-up sheet.
11. Verify the operation of all alarm devices and record as applicable on the start-up sheet. This may be accomplished either directly (e.g. lift the condensate pan switch to trip an alarm) or indirectly (lifting the wire indicated on the wiring diagram off of the input).
