The Trion CB777 Atomizing Humidifier system, rated 6 gallons per day, is ideal for a single room, wine cellars, walk-in humidors for cigars and return ducts. The same as the previous model 707U part number 356686-001. The CB777 is built to connect directly to a water supply and has all the characteristics required to effectively humidify a sizable area.
The CB777 works by spraying a superfine mist, swiftly absorbed by the atmosphere, increasing the relative humidity of the air. The humidistat, model 826, will turn the device on when the humidity level is below the set point and off when the set point is attained after the right humidity level has been established. There are no pads or filters to change, so maintenance is a breeze.
Features - Perfect for walk-In cigar humidors, wine rooms, grow rooms, greenhouses, and more
- Can be installed onto the return duct or as a free-standing in a room
- Humidify areas up to 3000 cubic feet
- Connect direct to water source
- The 120v humidistat can be wall or duct mounted for 20% to 80% R.H.
- Electrical: 120V, 75w
- Size: 12" (H) x 10.5" (dia)
Trion 707 Series Service
Water quality is a major problem causing corrosion and mineral build-up. Using a food service quality
water purifier with scale treatment will keep the 707u clean. The purified water will eliminate the white mineral dust that falls from the evaporating air and it
removes odors and corrosives such as chlorine and sodium. Common problems with the 707 series are:
- Gap between impeller and motor needs adjustment.
- Motor corrosion from hard water.
- Not draining the 707 off season causes motor seizure.
- Impeller and Pump Cap clog.
Instructions for setting gap:
Trion Impeller Adjustment 
These photos show a 707u used in a humidor. The photo on the right shows the 707u motor assembly. The motor still runs fine but the aluminum motor cap is heavily corroded from chlorine and has a heavy crust of lime.
The humidor environment runs year round and at a much higher humidity than a residential home. When under such heavy usage the water quality is most important. These photos would be much different if distilled quality water was used.
The centrifuge effect separates the once dissolved heavy minerals from the water. The very fine minerals create a slime. The slime leaves behind the dried residue in the 707 reservoir pan shown in photo.
Pure water is necessary for moist air with a clean taste and smell.
Removing the chorine smell is important for a humidor.
The filtration process of stripping the water of minerals can leave water acrid. The acrid water will cause corrosion. A simple
combination filter will remove the minerals, remove the odors, and treat the water with a softener that corrects the high PH.
Photo left shows the impeller pump clogged from the minerals. Removing the pump cap results in sediment falling out. This sediment caused un-balance. To clean the impeller, remove the pump cap. The cap is pressed-in and should simply pull-out. Run the cap under hot water if its stuck.
The unbalance caused the impeller to became loose. The setscrew appeared rusted but it was the brown mineral build-up. The impeller clearance from the base needs to be set to 1/16". The set screw was re-secure using a 1/16" allen wrench.
The Photo on the left shows the top of the impeller. Minerals have been centrifugally separated from the water. Use a pipe cleaner to clean the 6 small holes.
Water Treatment & Filtration Humidifier Reservoir Treatment
Corrosion has been major problem to humidifiers with a reservoir which are related to water quality.
The NuCalgon
4296-60 primarily used for keep condensate pan drain lines clear can also be used to treat humidifier. Pan-Treat tablets can be used to condition humidifier water in order to prevent odors and deposit build-up.
Pan-Treat is formulated with ingredients proven effective in cleaning and preventing these deposits, and its use will eliminate the extra maintenance costs associated with odors, mineral build up, plugged drains and overflows.
Easy to use and safe, water soluble, non-corrosive, non-toxic and biodegradable. Use 2-4 tablets every four to six weeks as needed. Clean and rinse out the humidifier's reservoir on a regular basis.
