Maintenance Requirements - S&P TR130 Manual De Uso

Purpose of a Total Recovey for All Climates (TR) System
Many modern homes are built air-tight for energy efficiency and
comfort. The result is that natural air infiltration rates are often
too low to provide acceptable indoor air quality. The solution is
to use an TR to remove gaseous pollutants such as odors, winter-
time excess humidity, formaldehyde, smoke, radon, vapors from
cleaning products, and other chemicals. Removal of dust and
other small particles from your home is not the function of an TR.
When should you use your TR?
Use the TR when windows are closed and ventilation is needed.
When the outdoor air is warmer or cooler than comfortable, the
TR allows a quieter, more secure home with the windows closed
and also saves energy.
Using an TR with air-conditioning:
An TR works very well with air-conditioning because its "enthalpy-
transfer" energy-exchange core reduces the amount of moisture
in the outside air that is brought in. TRs are the preferred way to
ventilate while air-conditioning because it brings in less moisture
than any other ventilation method.
Controlling excess humidity during cold weather:
When the TR is first turned on at the beginning of the heating
season (or when first installed), it will have to run full-time for
several days to reduce indoor humidity levels. A properly set
dehumidistat will do this automatically. If your control is the
proportional timer type (SPTL or SFM), it should be set to "100%"
for several days whenever you have a problem with excess
humidity during cold weather.
How much ventilation is right for you?
Always reference applicable codes and standards for ventilation
rate. Different households require different rates of ventilation,
depending on the pollutants found in each home. Most people use
one of two methods to control the operation of their ventilation
systems:
1. Provide a daily average of 0.35 Air changes per hour (ACH) for
your entire home. A proportional timer is the primary operating
control that allows you to reliably achieve this ventilation rate.
According to the American Society of Heating, Refrigeration and
Air-Conditioning Engineers (ASHRAE), this ventilation rate will
provide good air quality in most homes for most people.
At this rate, you will be changing the air in your home over eight
times per day. Most TR systems are generally designed to provide
at least this ventilation rate.
Be sure to provide at least 15 CFM per person in the home. In
small homes this may mean more than nine air changes per day.
Or, during the heating season in cold climates:
2. Ventilate enough in the winter to keep indoor humidity low. A
dehumidistat is the primary operating control that allows you to
maintain low winter humidity.
In the winter, water vapor inside your home mostly comes from
people –breathing, showering, and cooking. When the outside
air is 40 degrees F or less, a TR will reduce indoor humidity. This
helps to prevent condensation on windows.
High wintertime humidity generally means you need more
ventilation to control other indoor-air pollutants, like cooking
odors.

Maintenance Requirements

Due to continuing product development, specifications are subject to change without notice.
Use your judgment:
These guidelines are a starting point. As long as the pollutants
you are concerned with are detectable (like water vapor or
odors) your nose can be a good guide, and you may find that
fewer hours of operation will be sufficient.
For households with smokers:
Smokers will need at least double the usual ventilation rate to
satisfy non-smokers in the same household.
There is no known safe level of cigarette smoke. Any ventilation system may provide noticeable
improvement in spaces where cigarettes are smoked,
but it cannot be expected to protect against the
severe long-term health hazards of exposure to
cigarette smoke.
DO NOT WASH THE ENERGY EXCHANGE CORE.
Clean only as described above. The energy exchange
core can be replaced but is expensive.
