OPERATION 5
The Cube installs in the air inlet side of any heating and air conditioning system. Operation of air handler fan
unit is required for air purification to take place.
Note: UVC Germicidal ultraviolet lamps are wired to operate continuously. This feature allows the PRO-Cell™
catalyst to burn off surface impurities, cleaning and reactivating itself during periods of non-use or no airflow.
The Cube in recirculation mode combines three unique processes to protect against and significantly reduce
air pollutants. PRO-Cell™ Technology combines (1) MERV13 electrostatic high efficiency particulate removal
filter (2) UVC germicidal ultraviolet light that reacts to excite (3) a photo-catalytic oxidation (PCO) purification
process. This 3 stage purification process quickly removes submicronic particulate dust, inactivates
bioaerosols (germs, bacteria, mold spores), and eliminates volatile organic compounds (toxic gas-phase
chemicals) referred to as VOC’s.
There are many smart programmable thermostats that allow for automatic operation of the air-handler-fan unit
when there is no demand for heating or cooling. It is important that the Cube is operating twenty (20) to Thirty
(30) minutes every hour in a twenty four hour day to remove airborne contamination from the indoor
environment. Included with the Cube is the Healthy Home System Plus Control (HHSC+ by Field Controls).
The HHSC+ is a fan management control with a ventilation control option that is recommended to be installed
for precise air movement programming every half hour.
The length of operation depends on the location of the facility in relation to point source of pollution such as
refineries, processing plants, automobile traffic, hair salons, dog motels, fitness center locker rooms and areas
that produce high levels of pollutants. Individuals that are sensitive to mold spores, dust mites, chemicals or
have respiratory problems such as asthma, emphysema, and chronic allergies should extend run time 15 to 20
minutes every half hour in a 24 hour day.
AIR CYCLES PER HOUR
Fan Unit on 20 minutes per hour or 10 minutes every half hour
Fan Unit on 30 minutes per hour or 15 minutes every half hour
Fan Unit on 40 minutes per hour or 20 minutes every half hour
AIR CYCLES PER DAY (based on 24,000 cubic feet)
Fan Unit on 20 minutes per hour Air cycled (42) times per day
Fan Unit on 30 minutes per hour Air cycled (63) times per day
Fan Unit on 40 minutes per hour Air cycled (87) times per day
In the event, the existing thermostat does not have the capability to operate the air handler fan unit
independently of demand for heating or air conditioning, install Field Controls model HHSC+ Healthy Home
System Control Plus part number 46634200 included. The HHSC+ is a fan management and ventilation
control with the capability to program fan run time schedule every half hour for an even air cycle rate and a
more complete air purification operation.
The HHSC+ is simply wired in parallel with the existing thermostat. The HHSC+ memory tracks the time the
fan unit operates and only cycles the fan unit on when demand for heating and cooling have not met the fan
run time requirements for air purification. The HHSC+ also allows for programing notification for service of filter
and UVC germicidal lamp replacement.
