The Helios D35 removes 35 pints of water a day at AHAM conditions (80°F, 60% RH) and up to 70 pints a day at saturation (90°F, 90% RH), for spaces up to 1,000ft². It measures 16.40" x 11.25" x 10.76" and weighs 25.13 lbs, with a carry handle across the top.
It suits a small sealed crawl space, a basement room, a laundry or a closet. For a larger or wetter space, a bigger unit with a pump will keep up better.
The Helios D35 drains continuously through the included 6.5' hose. Pull the water plug, push the hose onto the gravity drain port and run it to a floor drain or sump, keeping the end of the hose lower than the outlet.
There is no built-in pump, so the unit has to sit above its drain. Stand it on blocks, or choose a pump model if the nearest drain is higher than the unit.
Set relative humidity from 35% to 90% in 1% steps, or switch to GPP mode and set moisture content from 25 to 200 grains per pound. Choose CO on either scale to run continuously. The unit starts at 50% RH out of the box.
After a power cut it restarts on its last mode and setting once the three-minute compressor delay has passed, so nobody has to go back under the house to switch it on.

No. It drains by gravity only, through the included 6.5' hose. The end of the hose must stay lower than the drain port, so the unit needs to sit above a floor drain or sump. If your drain is higher than the unit, choose a model with a built-in pump.
AlorAir rates the operating range at 37.4°F to 100.4°F. Auto defrost clears frost from the coil in cool conditions, and at 35.6°F or below the unit stops and shows LO until the space warms up.
AlorAir rates it at less than 52 dBA, which suits basements, bedrooms and offices where a louder commercial unit would be intrusive.
Yes. The Helios D35 is certified to Energy Star 6.0 and is ETL listed.
A grounded 3-prong GFCI outlet on a 15 A circuit, 115 V, 60 Hz. AlorAir advises against extension cords and plug adapters.
Remove the intake grille, take out the filter and clean or replace it, then refit the grille. AlorAir also recommends cleaning the coils once a year with a self-rinsing foaming coil cleaner. Unplug the unit first.
