Pre-Start

Pre-Start Checklist

Complete this checklist after installing the unit to verify all recommended installation procedures are complete before unit startup. This does not replace the detailed instructions in the appropriate sections of this manual. Disconnect electrical power before performing this checklist. Always read the entire section carefully to become familiar with the procedures.

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

Receiving

…Inspect unit and components for shipping damage. File damage claims immediately with the delivering carrier.

…Check unit for missing material. Look for ship-with drives, isolators, filters, and sensors that are packaged separately and placed inside the main control panel, fan section, or compressor section (see “Receiving and Handling,” p. 11).

…Check nameplate unit data so that it matches the sales order requirements.

Unit Location

…Remove crating from the unit. Do not remove the shipping skid until the unit is set in its final position.

…Ensure the unit location is adequate for unit dimensions, ductwork, piping, and electrical connections.

…Ensure access and maintenance clearances around the unit are adequate. Allow space at the end of the unit for shaft removal and servicing (see “Service Access,” p. 12).

Unit Mounting

…Place unit in its final location.

…Remove shipping skid bolts and skid.

…If using isolators, properly mount unit according to the isolator placement sheet.
