Where do you use the Sentinel HD55、HD90、HDi90 Dehumidifier?

The Sentinel Dehumidifier for crawlspaces and basements that are enclosed. The dehumidifier’s humidistat monitors the conditioned space and this is after the relative humidity of the space goes above the configured set point. The Sentinel works in a conditioned space to regulate the atmosphere of the place by withdrawing moisture from the atmosphere and do away with dampness of the place. The control area should be enclosed such that if it is a crawlspace all ventilations should be sealed with vapour barriers.

How should you use the Sentinel HD55、HD90、HDi90 Dehumidifier?

Illustrated is an explanation of how to use the Sentinel Dehumidifier to optimize its working capacity and efficient results:

  1. The Dehumidifier should be placed on a level surface and not directly on vapour barrier such as a dump basement.
  2. The drain option and transition should be carried out as informed in the unit’s manual so as to reach full capacity.
  3. The unit is switched on by pressing the power key on the remote.
  4. Settings are adjusted by use of the up and down arrow keys on the remote to aspired set point preferably 50-55%.
  5. While switching off the unit press the power key on the remote and ensure you do not unplug the power cord directly. Note after switch off, the fan continues rotating for about a minute.
  6. Sentinel drains itself during normal operation. While storing, give an allowance of at least 10 minutes for complete defrost then lean gently towards drain to ensure it is completely drained.
