Ductwork Considerations
Install all air ducts according to the National Fire Protection Association standards for the
"Installation of Air Conditioning and Ventilation Systems other than Residence Type (NFPA 90A)
and Residence Type Warm Air Heating and Air Conditioning Systems (NFPA 90B).
Make duct connections with a flexible material such as heavy canvas. If a fire hazard exists, Trane
recommends using Flexweave 1000, type FW30 or equivalent canvas. Use
three inches
for the
return duct and
three inches
for the discharge duct. Keep the material loose to absorb unit
vibration.
Run the ductwork as far as possible without changing size or direction. Do not make abrupt turns
or transitions near the unit due to increased noise and excessive static losses. Use elbows with
splitters or turning vanes to minimize static losses.
Poorly constructed turning vanes may cause airflow generated noise. Check total external static
pressures against fan characteristics to be sure the required airflow is available throughout the
ductwork.
Direct louvers up and down for condensers air discharge and intake so as to not short circuit
condenser air. Pitch outdoor ducts away from unit to protect unit from rain and snow entering with
condenser air. Auxiliary louvers and hoods may be required for this purpose. Attach ducts to unit
with canvas section duct connectors or other suitable noise and vibration absorbing devices.
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.
Electrical Requirements
WARNING
Ground Wire!
All field-installed wiring must be completed by qualified personnel. All field-installed wiring
must comply with NEC and applicable local codes. Failure to follow this instruction could result
in death or serious injuries.
WARNING
Grounding Required!
Follow proper local and state electrical code on requirements for grounding. Failure to follow
code could result in death or serious injury.
Electrical Requirements
Follow these guidelines, referring to unit wiring diagrams and supply power dimensional
information to ensure correct electrical requirements at the installation site. Reference supply
power wiring locations on unit submittals or in the
“Dimensions and Weights,” p. 11
section.
Specific unit wiring diagrams are provided on each unit. Use these diagrams for connections or
trouble analysis.
