The AlorAir Sentinel HDi100 is a crawl space, basement and whole-home dehumidifier with a built-in condensate pump. It removes 100 pints of water a day at AHAM conditions (80°F, 60% RH) and 78 pints a day at DOE conditions (73°F, 60% RH), covering up to 2,900ft² with 250 CFM of airflow.
A MERV-1 pre-filter and a MERV-10 filter protect the coils, and both ends of the cabinet can be ducted with 10" flex. For a large sealed crawl space or an open basement, the Sentinel HDi100 pumps its own condensate out and runs on its humidistat through the damp months.
Features
100 Pints a Day at AHAM
Removes 100 pints a day at 80°F and 60% RH, and 78 pints at 73°F and 60% RH, from a rotary compressor and 250 CFM of airflow.
Built-In Condensate Pump
Pumps water out through the drain hose automatically. The Drain button empties the reservoir before a move, and an E4 alarm flags a pump problem.
Two-Stage Filtration
Ships with a washable MERV-1 pre-filter and a MERV-10 filter, both reached from the intake side.
Microchannel Condenser
A microchannel condenser and a rare earth alloy tube evaporator, rated at 2.7 L/kWh on a 6.82 A draw.
Ducting on Both Ends
Inlet and supply each take 10" flex duct through optional adapters, up to a 10' total duct run.
Automatic Humidity Control
Holds any setpoint from 36% to 90%, switches to continuous mode below 36%, defrosts automatically down to 33.8°F and restarts on its last settings after a power cut.
Optional Wired Remote
AlorAir's remote runs on a 25' CAT 5 cable with its own humidity sensor, so you can control the unit from a living space.

Setup & Placement
Seal the space first: AlorAir specifies a vapor barrier and sealed vents in a crawl space. Stand the unit level on blocks or pavers rather than directly on the barrier, with 6' clear in front of the inlet and discharge. If it was tipped in transit, leave it upright for 2 hours before switching on.
Slide the compression nut over the drain hose, push the hose fully onto the fitting and tighten the nut, then route it to a drain, sump or outside. For ducted installs, keep the total duct run within 10'. Plug into a grounded 15 A GFCI circuit.
