  • Page 7: General Information

    General Information Installation procedures should be performed in the sequence that they appear in this manual. Do not destroy or remove the manual from the unit. The manual should remain weather-protected with the unit until all installation procedures are complete. Note: It is not the intention of this manual to cover all possible variations in systems that may occur or to provide comprehensive information concerning every possible contingency that may be encountered during an installation.
  • Page 8 General Information NOTICE: Equipment Damage! Use spreader bars to prevent straps from damaging the unit. Install the bars between lifting straps, both underneath the unit and above the unit. This will prevent the straps from crushing the unit cabinet or damaging the unit finish. Before preparing the unit for lifting, estimate the approximate center of gravity for lifting safety.

  • Page 9: Pre-Installation

    Pre-Installation The final position for the air handler must be dictated by required service access to it, weight distribution over structural supports, and by the locations of electrical, refrigerant and condensate drainage connections. After this is determined, the following preparations should be made. Repositioning Drain Pan These air handlers come with one drain pan that can be installed in any one of four positions;...
  • Page 10 Pre-Installation Process for Drain Pan Relocation Figure 2. Drain Pan Relocation 1. Remove the access plate at the opposite end of the drain connection. This plate secures and lifts the back end of the drain pan for sloping. It must be removed before the drain pan can be removed.

    Pre-Installation Field Conversion to 460 Volt WARNING Hazardous Voltage w/Capacitors! Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. For variable frequency drives or other energy storing components provided by Trane or others, refer to the appropriate manufacturer’s literature for allowable waiting periods for discharge of capacitors.
