AIR™ SYSTEM FEATURES
DigiAIR™ is a factory added module to an Amana brand PTAC
to provide for outside makeup air that is dehumidified when
needed:
1. Lower installation and renovation costs than typical
central dedicated outdoor air systems (DOAS).
2. Configurable dehumidification settings based on
HVAC industry psychometric data. Configuration can
easily and accurately be adjusted through a few but-
ton clicks of the PTAC touchpad by any authorized site
personnel.
3. Outside Makeup air volumes of up to 75 CFM.
4. Drier room conditions (lower RH %) usually means that
room occupants will feel comfortable at higher sen-
sible temperatures saving PTAC operational costs.
5. Optional 250 watt electric heater to warm colder out-
side air when needed.
6. Filter to assist in keeping the DigiAIR™ coils cleaner
to maintain dehumidification and outside air flow.
Permanent and washable.
7. Vent door is configurable to either be open 100% of
the time or can be closed if codes permit intermittent
operation.
8. Future, optional Web access to allow monitoring and
configuration access through an Amana DigiSmart /
DigiLink internet connectivity.
INSTALLATION INSTRUCTIONS
The DigiAIR™ makeup air and dehumidification module is
factory installed to the PTAC partition panel and base pan
as shown in Figure 2. The optional heater, to raise the inlet
air temperature in cold climates, is attached to the indoor
section of the partition panel. The DigiAIR™ power switch is
shipped from the factory in the “off” position. Before in-
stalling the PTAC front cover, change the DigiAIR™ power
switch to the “on” position if makeup air is desired. The
DigiAIR™ power switch is located on the front of the PTAC
control and is visible when the front is not installed. Also,
if the DigiAIR™ vent door is to be manually secured in the
open position, the vent door screw must be inserted before
the PTAC is installed into the wall sleeve.
