Unit Start-Up (Continued)

Final Unit Checkout

After completing all of the checkout and start-up procedures outlined in the previous sections (i.e., operating the unit in each of its Modes through all available stages of cooling and heating), perform these final checks before leaving the unit:

[ ] Close the disconnect switch or circuit protector switch that provides the supply power to the unit's terminal block 1TB1 or the unit mounted disconnect switch 1S14.

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote discon- nects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvert- ently energized. Failure to disconnect power before ser- vicing could result in death or serious injury.

HIGH VOLTAGE IS PRESENT AT TERMINAL BLOCK 1TB1 OR UNIT DISCONNECT SWITCH 1S14.

[ ] Turn the 115 volt control circuit switch 1S1 "Off".

[ ] Turn the 24 volt control circuit switch 1S70 to the "On" position.

[ ] At the Human Interface Module, press the "SETUP" key. The LCD screen will display various preset "parameters of operation" based on the unit type, size, and the in- stalled options. Compare the factory preset information to the specified application requirements. If adjustments are required, follow the step-by-step instructions pro- vided in the appropriate SAHF-PTG manual for CV or VAV applications.

[ ] Program the Night Setback (NSB) panel (if applicable) for proper unoccupied operation. Refer to the programming instructions for the specific panel.

[ ] Verify that the Remote panel "System" selection switch, "Fan" selection switch, and "Zone Temperature" settings for constant volume systems are correct.

[ ] Verify that the Remote panel "System" selection switch and the "Supply Air Temperature" settings for variable air volume systems are correct.

[ ] Inspect the unit for misplaced tools, hardware, and de- bris.

[ ] Turn the 115 volt control circuit switch 1S1 "On".

[ ] Press the "AUTO" key at the Human Interface Module to begin system operation. The system will start automati- cally once the dampers modulate and a request for either heating or cooling has been given.

[ ] Verify that all exterior panels including the control panel doors and condenser grilles are secured in place.
