APPLICATION CONSIDERATIONS
HIGH VOLTAGE HAZARD
Failure to follow this warning could result in personal injury
or death.
This Air Purifier utilizes high voltage. If you notice water
running into or around the Air Purifier, water stains on the
purifier cartridge or on the Enhancement Module walls or
cabinet, shut off the Air Purifier and call your service provider.
!
WARNING
The 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 Air Purifier is
not designed to operate when wet. Operation of the 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 and humidifiers.
The Air Purifier should be installed in a system so that all the
return air is circulated through the 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 Air Purifier.
Humidifiers
An evaporative humidifier can be mounted upstream of the Air
Purifier but the recommended location of any humidifier is
downstream of the Air Purifier. It is necessary to install atomizing
humidifiers downstream of the Air Purifier because hard water salt
deposits and water droplets may damage Air Purifier.
Ensure that the humidifier installation will not allow water or water
droplets to enter the Air Purifier because it may cause electrical
arcing or damage the Air Purifier.
NOTE
: For fan coil installations, do not install the humidifier in
the fan coil access doors or cabinet.
Inspect for plugged drains and maintain humidifier drain lines on a
regular basis to avoid overflow of water into the Air Purifier. The
recommended inspection should be done at every change of the
Air Purifier cartridge (generally 8--12 months).
HIGH VOLTAGE HAZARD
Failure to follow this warning could result in personal injury
or death.
This Air Purifier utilizes high voltage. If you notice water
running into or around the Air Purifier, water stains on the
purifier cartridge or on the Enhancement Module walls or
cabinet, shut off the Air Purifier and call your service provider.

WARNING
Transitions
If the return air duct or furnace openings do not fit the Air Purifier
cabinet openings, gradual transitions are recommended to reduce
air turbulence and maximize efficiency. No more than 45
_
(about
8.5 inches per running ft.) of expansion should be used on each
side of the transition fitting.
Turning Vanes
If the Air Purifier is installed adjacent to a 90
_
duct elbow, turning
vanes should be added inside duct to improve air distribution
across the face of the Air Purifier.
Electrical Power and Flow Sensing
The Air Purifier should only be powered when airflow is present.
The furnace control EAC terminals provide power only when the
furnace blower is operating. Air Purifier models PGAPAXX1625
and PGAPAXX2025 are designed to be powered from the
electronic air cleaner (EAC) terminals on a furnace electronic
control. If EAC terminals are not available, the Accessory Flow
Sensor Kit, model KIT--160--000, must be purchased for use with
the Air Purifier. Air Purifier models PGAPAXX1620,
PGAPAXX2020, and PGAPAXX2420 include the flow sensor as
standard equipment as they are designed primarily to be installed
with fan coil air handlers. A Flow Sensor Jumper Accessory Kit,
KIT--161--000 is available should there be a need to use Air
Purifier
model
PGAPAXX1620,
PGAPAXX2020,
or
PGAPAXX2420 with a furnace that has EAC terminals.
Electrical Power Fusing
Air Purifier models PGAPAXX1620, PGAPAXX2020, and
PGAPAXX2420 include in-line fuses necessary for installation
with fan coil air handlers. Air Purifier models PGAPAXX1625 and
PGAPAXX2025 do not include in-line fuses as they are designed
to be powered from the electronic air cleaner (EAC) terminals on a
furnace
electronic control,
which
are
already
properly
current-limited for Air Purifier application. If there is a need to use
Air Purifier model PGAPAXX1625 or PGAPAXX2025 with a
230VAC fan coil air handler or other high-current source, the
Accessory Fuse Kit KFAPS0110KIT must be ordered and installed
per the instructions included within the kit.
Accessory Safety Screen
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury
or death.
The Air Purifier contains high voltage electrodes and as
supplied is designed to be installed in a completely enclosed
duct system in order to prevent access to high voltage during
operation of the purifier. If there is a need to operate the
purifier as the first element in a duct system (thereby locating
the inlet of the purifier in a position that could be touched
during operation), the Accessory Safety Screen Kit, listed in
the table below, must be purchased for use with the purifier.
