Instructions Before Use

The unit should be used under the following conditions:

  1. Place on a stable, non-combustible flat surface
  2. Ambient temperature of 5 ~ 35 ℃
  3. Relative humidity ≤ 85%
  4. Atmospheric pressure: (86 ~ 106) KPa
  5. Altitude not higher than 2000 meters
  6. Power: 5L AC 110V±10%/60HZ, 20L: AC230V±10%/60HZ
  7. Keep away from any heat, corrosive gasses, strong vibration and electromagnetic sources.
  8. Provide a minimum of 300mm of space for proper ventilation (front and rear)
  9. Do not spill liquid anywhere other than the bath.
  10. When setting temperatures pay attention to freezing points (ethanol/ethylene glycol).
  11. When operating for the first time after replacing the heat transfer fluid there may be air trapped in the circulating pump, follow these instructions to purge:
  • a. Disconnect the outlet line from the application NOTE: Fluid may leak from application, be ready with a bucket or plug the port. Hold the Outlet hose above the top of the bath so fluid does not drain out.
  • b. Place the outlet hose into a clean collection bucket.
  • c. Hold the outlet hose firmly so it does not fall out of the collection bucket
  • d. Wearing safety glasses to shield any splashes, turn on the circulating function.
  • e. After the liquid flow significantly increases, turn off the circulator.
  • f. Reconnect the hoses to your application’s ports.
