SAFETY INSTRUCTIONS
Before installing the Cube, inspect packing for any signs of damage. During handling and installation, take care
to protect the PRO-Cell™ honeycomb catalytic side of the product from physical damage, as the aluminum
honeycomb substrate is soft and can easily be scored.
Warning - Always unplug the power cord from the Cube air purification system when changing the filter or
germicidal ultraviolet lamps. Never look into an illuminated ultraviolet lamp as severe damage to the eyes will
result.
The Cube is rated for standard ambient air temperatures during heating and cooling functions. The Cube is
not rated for temperatures in excess of 125 Degrees Fahrenheit / 52 Degrees Celsius.
Do not attempt to clean the PRO-Cell™ honeycomb catalyst with cleaning solutions. The PRO-Cell™ catalyst
is radiated with short wave germicidal ultraviolet light during periods of airflow and is self-cleaning.
Do not install insulation within 76mm or 3 inches of any illuminated ultraviolet lamps.
Access for service is required when mounting above suspended ceilings, and / or behind walls.
Do not install in a position where the interior modules can fall from an elevated positon and cause injury to
people or equipment.

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.

REPLACING UVC GERMICIDAL LAMPS 7
1. Always wear protective eye goggles when servicing UVC germicidal lamps.
2. Unplug the power cord from main outlet on the Cube unit.
3. Remove the central Cube metal cover which is held in place with eight (8) screws. This will allow
access to the 3 PRO-Cell™ modules and electronics.
4. Next to the MERV13 filter is the PRO-Cell/MM2025C Master Module. Unplug the power cord, remove
service panel metal cover from the PRO-Cell/MM2025C Master Module and set aside metal cover.
5. The remaining two modules are the PRO-Cell/SM2025 Slave Modules. Unplug the low voltage wires
from the master module and the two slave modules.
6. Unplug the UVC germicidal lamp wires from each of the lamp connections.
7. Each module is held in place by a retaining bracket by two (2) thumb screws. Unscrew the thumb
screws. Set aside thumb screws and retaining brackets.
8. Carefully slide forward the PRO-Cell™ Module to a point where access to the far end of the UVC
germicidal lamps can be reached, or fully withdraw the module completely from the frame. Loosen the

INSTALLATION 9
Note: Upon installation pay close attention to the Cube directional airflow inlet. Airflow inlet is at the MERV13
Pre Filter as illustrated in Figure 1 illustration below.
The Cube is designed to be installed into a HVAC or AHU distribution system. It is recommended that a
plenum is created into which the Cube can be integrated in a completely airtight installation. Several Cube
units may be installed side by side, one on top of the other, or both. Be certain to provide for a door open
access to service covers.
TRANSITIONS FOR IN-DUCT MOUNTING
Metal adapter of 18 gauge sheet metal or greater and insulated, should be fabricated to make suitable
transitions. Attach the transitions to the Cube and fasten with #10 x 1/2 self-tapping sheet metal screws.
(See Figure 2 illustration on following page)
1. Tape all seams between the air handler / blower return side and the outlet side of the Cube so not to
allow air bypassing the system.
2. Program the thermostat or HHSC+ Fan management control to operate fan for at least 10 minutes
every half hour. Increase cycle rate of fan run time to meet desired air quality requirements.
