Due to the extra starting power provided by the 28.5 Volt batteries, turbine engines will experience faster, cooler starts and extended turbine life. This model is primarily designed for superior starts on large turbine engines and the Garrett TPE 331.
  
  
• This unit is more economical than the 3328 as it does not incorporate the high output DC power supply. Also this unit can be configured 110 Volt or 220 Volt AC input. This unit weighs 185 lbs/83.92 kilos.

Always recharge the GPU until the green light appears. Once charged, it is not necessary to leave unit plugged in. If heater is installed, turn unit off but leave plugged in.
