GENERAL INFORMATION
The EVENAIR
The EVENAIR
®
should be installed in branch ducts serving individual rooms, where proper air flows cannot be achieved.
®
is not designed for installation in the main air supply ducts. Locating the EVENAIR® near the outlet end of
a problem branch duct will provide the best performance.
The EVENAIR
EXAMPLE: Use the 6" KS EVENAIR
®
is designed to operate in round metal or flexible type ducts.
®
for 6" ducts and the 8" KS EVENAIR
indicated or for rectangular ducts, use the Model JR-1 or JR-2 EVENAIR
CAUTION: The EVENAIR
®
should not be installed into vertical duct pipes. Do not use this product on clothes dryer vent
pipe.
®
for 8" ducts. For larger duct diameters than
®
or the Model AB-1 Air Booster.

INSTALLATION INSTRUCTIONS
Locate the EVENAIR
®
in the duct pipe near the problem area.
Allow adequate space for the removal of the unit for servicing
or annual inspection.
OR METAL DUCT PIPE 1
F
1. Separate the duct at a joint near the problem area and cut
6-3/4" off the end of the duct pipe. (See Figure 1)
2. An alternative method is to cut a 5-3/4" section out of the
duct pipe. (See Figure 2) Then crimp the end of the duct
pipe with at least 1" crimp. (See Figure 3)
3. Install the EVENAIR
®
unit with the crimped end pointing toward the problem area.
(See Figure 3) Secure the unit with sheet metal screws and seal joints with duct tape.
Support the unit with an acceptable hanging method.
4. (Complete this step for KS-5, KS-6 & KS-8 ONLY.) Remove center knockout from the
outlet box bottom. (See Figure 3A) Before installing the EVENAIR
®
into the duct pipe,
fasten the outlet box onto the unit housing with the #10-32 UNF screws and nuts
provided. (See Figure 3B)
F
OR FLEXIBLE DUCT
1. Cut and separate the flexible duct. Fold back the outer insulation on the duct
to expose the flexible duct material. (See Figure 4)
2. Insert the EVENAIR
®
unit, with the crimped end pointing toward the problem
area, into the flexible duct and secure with duct tape. (See Figure 4)
3. Support the unit with acceptable hanging method. Then re-install outer
insulation and secure with duct tape. Allow room for installation of an
electrical junction box.

UNIT WIRING INSTRUCTIONS
A permanent wiring method must be used for power connection. It is recommended that a minimum size of 14 AWG wire
for electrical supply connections and wiring should be suitable for 90
o
C (194oF) temperature. The EVENAIR® should be
wired with an overcurrent protection device (fuse or circuit breaker) rated 15 amperes or less. Wiring method should be in
accordance with the National Electrical Code and any local code requirements. All wiring connections should be within an
electrical junction box.
CAUTION: Disconnect electrical power before wiring. Do not
route electrical wiring along heated duct pipes. Unit should be
grounded.
W
IRING METHOD NO.1 (See Figure 5 for wiring diagram)
Controlling the EVENAIR
switch. This method allows for manual control of the EVENAIR
®
through a standard ON/OFF wall
®
unit in the area desired.
W
IRING METHOD NO.2 (See Figure 6 for wiring diagram)
Controlling the EVENAIR
conditioning forced air system. This method allows for
automatic operation of the EVENAIR
EVENAIR
®
is wired in parallel with the appliance blower
motor. This operates the EVENAIR
®
through a central heating/air
®
unit. The
®
whenever the
Figure 5
appliance blower operates.
CAUTION: Do not wire the EVENAIR
®
to an appliance
blower motor if:
1. The appliance blower motor is not rated for 120 volts
AC single phase and operating at 60 cycles.
2. The blower motor control is a variable speed tap type,
solid state speed control or any of the type of controls not
designed for dual motor control. Consult appliance
manual for this information.
W
IRING METHOD NO.3 (See Figure 7 for wiring diagram)
Controlling the Air Booster through a Field Controls ABA-1 Air Booster
Activator, for automatic control of the Air Booster without wiring directly to
the appliance blower motor.
NOTE: All wire splice connections should be made within an electrical
junction box.
MAINTENANCE
CAUTION: Disconnect electrical power supply before performing
maintenance.
Periodic removal and cleaning of the EVENAIR
forced central heating/air conditioning systems. Annual removal and
cleaning of the EVENAIR
®
unit is recommended for gravity warm air
®
unit is recommended for
heating systems not equipped with a return air filter.
