RGAP(A,B)XX: Installation and User Instructions

Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

Ozone Production

This  product  complies  with  the  maximum  allowable  concentration  of

ozone of 0.050 parts per million by volume (ppmv) in a 24-hour period.

APPLICATION CONSIDERATIONS

The Return Air Purifier is designed for use in the return air  duct of a

forced air heating, cooling, and ventilation system. Although designed to

be  a  robust  air  purification  system,  the  Return  Air  Purifier  is  not

designed to operate when wet. Operation of the Return Air Purifier in a

wet  environment  will  result  in  less  than  optimal  performance  and  a

possible safety hazard. As such, particular attention must be paid to the

following paragraphs regarding installation near air conditioning coils.
The Return Air Purifier should be installed in a system so that all the

return  air  is  circulated  through  the  Return Air  Purifier.  It  should  be

located upstream of both the furnace and the air conditioning evaporator

coil.  This  will  help  keep  the  furnace  and  evaporator  coil  clean  and

prevent condensation from forming within the Return Air Purifier. 

Transitions

If  the  return  air  duct  does  not  fit  the  Return  Air  Purifier  cabinet

openings, a gradual transition is recommended to reduce air turbulence

and maximize efficiency. No more than 45° (about 8½" per running foot)

of expansion should be used on the transition.

Electrical Power and Flow Sensing

The Return Air Purifier should only be powered when airflow is present.

The  furnace  control  EAC  terminals  provide  power  only  when  the

furnace  blower  is  operating.  Return  Air  Purifier  RGAPAXX1625  is

designed to be powered from the electronic air cleaner (EAC) terminals

on a furnace electronic control.

Accessory Safety Screen (KIT170000)

Electrical Power Fusing

with Furnace

Return Air Purifier RGAPAXX1625 does not include in-line fuses as it

is  designed  to  be  powered  from  the  electronic  air  cleaner  (EAC)

terminals  on  a  furnace  electronic  control,  which  are  already  properly

current-limited for Return Air Purifier application.

with Fan Coil

Return Air Purifier RGAPBXX1625 does include in-line fuses as it is

designed  to  be  powered  from  the  transformer  on  fan  coil  unit

installations (
