Startup Checklist
Insulate all cold surfaces to prevent condensation. Moisture mixed
with accumulated dirt and organic matter may create an amplification
site for microbial growth (mold) causing unpleasant odors and health-
related indoor air quality (IAQ) problems.
The Trane Company recommends field-insulation of the following
areas to prevent potential condensate and IAQ problems:
1. Supply and return water piping connections
2. Condensate drain lines and connections
3. Fresh air intake duct connections
4. Discharge duct connections
5. Wall boxes
