Page 9: Performance Data
**Approximately 95 cfm with optional power vent kit. Actual vent cfm performance will vary due to application and installation conditions. Notes: 1. All 265 volt models must use Trane’s subbase or Trane’s hard-wire junction box kit. 2. Minimum branch circuit ampacity ratings conform to the National Electric Code. However, local codes should apply. - Page 10 Notes: 1. All 265 volt models must use Trane’s subbase or Trane’s hard-wire junction box kit. 2. Heating capacity and efficiency is based on unit operation without condensate pump. Unit automatically switches to electric heat at 25°F outdoor coil temperature. Depending upon relative humidity conditions, this will occur at approximately 35°F outdoor ambient temperature.
- Page 11 3. Overcurrent protection for all units without electric heaters is 15 amps. Overcurrent protection on 265 volt models must be cartridge-style time delay fuses (included and factory installed on Trane chassis). 4. Total watts for 7,000 and 9,000 Btu models; add 70 watts for size 12 and for size 15.
