The AlorAir Helios MP55 is the larger Helios pump model, removing 55 pints of water a day at AHAM conditions (80°F, 60% RH) and up to 120 pints a day at saturation (90°F, 90% RH), for crawl spaces and basements up to 1,500ft².
Its 167 CFM airflow and built-in pump suit bigger or wetter spaces, lifting condensate up to 19.6' to a sink, window or sump. The Helios MP55 weighs 43.21 lbs, stands on adjustable leveling feet and can also drain by gravity through the included 6.5' hose.
Features
167 CFM for Up to 1,500ft²
55 pints a day at AHAM and up to 120 at saturation, the higher-capacity Helios pump model for larger or wetter spaces, rated at 58 dBA.
Built-In Condensate Pump
Lifts water up to 19.6' through the included 19.6' pump hose to a sink, window or sump. The one-touch Drain button runs the pump on demand.
Gravity Drain Option
Where a drain sits below the unit, remove the water plug and use the included 6.5' hose instead.
%RH or GPP Control
Set humidity from 20% to 80% in 5% steps, or grains per pound from 20 to 200, with a CO setting for continuous running.
Automatic Defrost
Clears frost from the coil in cool crawl spaces so drying continues through the cold months.
Memory Restart
After a power cut it returns to its last mode and setting on its own, after a three-minute compressor delay.
Leveling Feet and Carry Handle
Adjustable leveling feet steady it on uneven floors, and the top handle makes it easy to carry into a crawl space.
Remote and Terminal Ready
A controller port takes AlorAir's optional remote control (sold separately), and an A1-A6 auxiliary terminal connects external devices.

Setup & Placement
Place the unit in an enclosed space, upright near the floor and central to the area, with at least 6" of clearance around the air intake and exhaust. Level it on its adjustable feet, or hang it from joists with a hanging kit (sold separately). Leave it upright and out of the box for 24 hours before first use.
For pump drainage, fit the 19.6' hose to the pump outlet and run it to a sink, sump or outside. For gravity drainage, remove the water plug, fit the 6.5' hose and keep its end below the outlet. Plug into a dedicated, grounded 15 A GFCI circuit.
