APPLICATION CONSIDERATIONS
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.
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).
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 foot) 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 DGAPAXX1625 and
DGAPAXX2025 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 ( Table 5 )
must be purchased for use with the air purifier. Air purifier models
DGAPAXX1620, DGAPAXX2020, and DGAPAXX2420 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
( Table 5 ) is available should there be a need to use air purifier model
DGAPAXX1620, DGAPAXX2020, or DGAPAXX2420 with a furnace
that has EAC terminals.
Electrical Power Fusing
Air purifier models DGAPAXX1620, DGAPAXX2020, and
DGAPAXX2420 include in-line fuses necessary for installation with fan
coil air handlers. Air purifier models DGAPAXX1625 and
DGAPAXX2025 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
DGAPAXX1625 or DGAPAXX2025 with a 230VAC fan coil air handler
or other high-current source, the Service Quick Kit ( Table 5 ) must be
ordered and installed per the instructions included within the kit.
Accessory Safety Screen
Duct Hardware Upstream of Purifier
Any equipment mounted in the duct or duct parts such as turning vanes
installed in the duct upstream of the purifier must be kept at least 1¼
inches from the front face of the air purifier.
INSTALLATION
Check Air Purifier Components
Carefully remove all items from the box ( Fig. 2 ).
WARNING
!
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
!
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.
