♦
Before servicing or cleaning the unit, unplug the unit line
cord.
♦
Make sure unit is not running before opening its door.
Blower wheels are sharp and can cut.
♦
Do not disable the interlock switch: it is there for your
safety.
Service filters regularly:
Service filters every three months when the unit is in regular
use or as needed to keep them reasonably clean.
1.
Release cam latches and carefully swing access door
open. Remove the door by sliding to one side.
2.
In EV130/200/300, remove filter clips.
3.
Pull the filters out.
4.
Vacuum with a hose attachment.
5.
Re-install filters and filter clips, (see illustrations,
page 7).
6.
Re-install door, and fasten cam latches.
NOTE:
The filters should be replaced after they have been
cleaned several times. The primary contact for replacement
filters for your RenewAire unit is the installing contractor. As
an alternative, you may wish to produce your own filters.
Please follow these instructions:
Filters may be cut from a sheet or roll of ¾” - 1” firm, spun
polyester filter “hog hair” media or material, similar to the
existing filter in the residential unit.
The size of each filter (2 required per unit) is as follows:
EV130
10 ½” x 10 ½”
EV200/EV300
10 ½” x 21 ¾”
Call your HVAC contractor or RenewAire for further
information.
NOTE: Filters must be used
or the face of the energy
exchange core will become blocked by dust. The filters
supplied in the unit are usually able to keep the energy
exchange core clear for many months. Finer filters can be
used but must be cleaned more often.
Clean the face of the energy exchange core yearly:
1.
Remove the filters (see above).
2.
Vacuum the exposed faces of the energy exchange
core with a soft brush attachment.
3.
After servicing the filters, re-install them (see above).
4.
Vacuum out dust from the rest of the unit case.
Dust collects only on the entering faces of the energy
exchange core. The interior of the energy exchange core stays
clean even if the core faces are dust covered.
CAUTION
D
O NOT WASH THE ENERGY EXCHANGE CORE
.
Clean only as described above. The energy exchange core can
be replaced but is expensive.
The blower/motor package needs no lubrication:
Vacuum clean the blower wheels at the same time you clean
the face of the energy exchange core.
Purpose of an Energy Recovery
Ventilation (ERV) 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 ERV to remove gaseous pollutants such
as odors, winter-time excess humidity, formaldehyde, smoke,
radon, vapors from cleaning products, and other chemicals.
The removal of dust and other small particles from your home
is not the function of an ERV.
When should you use your ERV?
Use your ERV when windows are closed and you need to
ventilate. When the outdoor air is warmer or cooler than
comfortable, the ERV will allow a quieter, more secure home
with the windows closed and will also save energy.
Using an ERV with air-conditioning:
An ERV works very well with air-conditioning, because its
“enthalpy-transfer” energy-exchange core will reduce the
amount of moisture in the outside air that is brought in. ERVs
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 ERV 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 (PT or FM), it should be
set to “100%” for several days whenever you have a problem
with excess humidity during cold weather.
