HRV UNIT
AristotleAir®units contain an HRV (Heat Recovery Ventilator) with fully featured 5-speed
electronics to provide complete ventilation control. The HRV unit in each AristotleAir®is a
LIFEBREATH Model 300 DCS (Double Core System for Maximum Recovery) and is
manufactured by AIRIA Brands, Inc.
An HRV is designed to provide fresh air into a building while exhausting an equal amount
of stale air. During the winter months, the incoming cold, fresh air is warmed utilizing the
heat recovered from the stale air before it is exhausted to the outdoors. The core in an
HRV transfers heat from one air stream to the other without mixing air.
Before installation,
careful consideration
must be given to how
this system will operate
when connected to
other existing me-
chancial and electrical
systems, i.e., a boiler
system. All standard
installation procedures
for shutting off water
supply, draining pipes,
and tagging out elec-
trical energy sources
should be followed for
installation.
NEVER install a unit in
a situation where its
normal operation, lack
of operation or partial
failure may result in the
backdrafting or improp-
er function of vented
combustion equipment.

THE MATRIX
The matrix of titanium dioxide infused activated carbon cells
inside APCO® RT attracts and holds odors, microbes, and VOC
molecules which are then catalyzed by exposure to UV light.
The carbon cells are self-cleaning and the system is virtually
maintenance-free other than lamp replacement.
Fight Germs & Odors Without Ozone
Unlike many air-cleaning devices, APCO® produces no ozone. UV-C light shining
on the APCO® activated carbon matrix causes a photocatalytic reaction which
transforms odor molecules into harmless water vapor and CO2 which are released
into the airstream.
Mold, germs, and viruses are sterilized by UV-C light shining on the carbon matrix
and in the air as they pass by.
APCO® RT
The Fresh-Aire UV APCO® RT (remote tether)
system works with your central air system to
reduce odors, toxic chemical vapors, germs
and mold in your home. APCO® RT uses the
same technology as the standard APCO unit
but is easier to install in tighter spaces.

How APCO® Works
APCO® RT removes airborne contaminants as the air is
circulated by the central air system.
Airborne microbes and volatile organic compounds (odor
molecules) are captured by the APCO® activated carbon
matrix and held in place by the microscopic structure.

AristotleAir®Owners Manual - 4/2012
SECTION 3: PRODUCT OVERVIEW
OPERATIONS / HOW IT WORKS
A standard, older-style system has two modes: Occupied and Unoccupied.
While in Occupied Mode, the system’s dampers open, allowing fresh air to enter the room to
keep the CO2 level under specified levels. In order to keep building pressure in balance, there
is a fan (with a 1-speed fan motor) on the roof to pull warm air out of the room. One fan can
control 4-6 rooms.
When in Unoccupied Mode, the dampers close and the air is recycled in the room. This
system also allows 750-1,750 CMF’s into the space. (Note: ASHGE Standards are 10 CFM per
person. 20 people = 200 CFM). These dampers are made of metal and in most cases, when
fully closed, there is approximately 20% air leakage. This damper is the only element between
the water coil and outside air and the reason for coil freeze ups. This damper is located at an
opening at the ground level and can cause snow and ice build-up and leakage into the room.
The coil must be removed to clean, which is another disadvantage.
The AristotleAir®system works in the same manner with these key exceptions:
1) It controls the amount of fresh air brought in (10 CFM per person).
2) Rather than discharging the room air out to the atmosphere – as in the old system – the
air passes through heat recovery coils to retain 88% of the energy. This reduces the
amount of energy required to maintain desired room temperatures.
3) In addition, before filtering into the room, all of the air passes through a bacterial-killing
light system for added health benefits.
4) When rooms are unoccupied, the AristotleAir®system reverts to low fan speed, or can be
cycled off, for additional electrical cost savings.
5) This is a self-balancing system. The amount of outside air brought in is the same
as the amount being discharged, elimininating the need for an exhaust fan.
6) The dampers have a rubber seal and closes against a plastic seal ring. The water coil
is located at the top of the unit and the intake and exhaust can be located 30” above
ground. The path through the heat exchanger and connecting ductwork makes the
chance of freezing to almost non-existent: no snow or ice buildup. The filter location
makes maintenance easy. If the heat exchangers need cleaning, they slide out and
wash easily. There is also access to the coil for easy cleaning.
