allow the air to move freely and easily through the ducts. See
chart under System Layout to size your ductwork:
If duct runs are very long (over 25 feet of flex duct for 130
CFM or over 10 feet for 200 CFM each run) or have excessive
bends or elbows or if maximum air flow rates are required,
eight inch insulated flexible duct should be used. The outer
flange of the duct collar can be used for both the inner and
outer jacket of the flexible duct. Care must be taken to insure
that the duct is securely fastened and sealed to the duct collar.
Do not use more flex duct than necessary!
Flex duct is much more resistant to airflow than rigid duct;
longer runs of flex duct will reduce the ventilation
performance of your system. Stretch flex duct and avoid sharp
bends.
CAUTION
♦
Do not connect Dryers directly to the unit.
♦
Do not connect Range Hoods to the unit.
Installing Fresh Air (FA) ducts:
Use a five foot section of flexible insulated duct to connect the
unit to the ducts at the port labeled
Fresh Air to the Inside
.
This will cut noise transmitted from the unit. Stretch the flex
duct tightly in order to maintain good airflow.

Optional controls:
RenewAire offers a variety of controls specifically designed to
work with the EV130/200/300 products. These include: PTL
(a two wire percentage timer), FM (a six wire percentage timer
that will interconnect with the furnace blower), and PBL
(point of use push button control). Other controls that throw an
unpowered switch may also be used.
Typical control schematic:
Various wiring designs can be used to properly control the
unit and meet safety and code concerns. Consult your
electrician for an electrical design to meet your needs.
The schematic below shows a typical control system: a PTL
percentage timer plus two PBL push-button controls.
See installation manuals for the control(s) you select for
wiring diagrams and specific instructions.
If NOT connecting controls to the ERV:
Make a jumper out of a short piece of wire. ERV will run full-
time once its power cord is plugged in.
Starting Up the Unit
♦
Inspect your installation to be sure all duct work is
correctly installed and sealed, that filters are in place, and
controls (if any) are connected.
♦
Shut and latch the door to the unit.
♦
Plug unit into 115 VAC outlet. It may start immediately.
♦
Use control to turn on the unit. Check operation of the
