Dear Gabe Smith,

Thank you for your interest in the Sentinel HDI90.

Regarding your question about the maximum drain hose length (assuming no more than 2 feet of vertical lift), please see the details below:

Built-in Drain Hose Length:
The Sentinel HDI90 comes with a 19.6 ft (approximately 6 meters) drain hose.

Maximum Pump Head (Lift Height):
The built-in condensate pump has a maximum lift height of 14.7 ft (approximately 4.5 meters).

Practical Recommendations:

  • If the vertical lift does not exceed 2 feet, the drain hose can be extended horizontally to a length close to the pump's maximum lift equivalent. However, it is recommended that the total equivalent length does not exceed 14.7 feet to avoid affecting drainage efficiency.
