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 (194 o F) 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 M ETHOD N O .1 (See Figure 5 for wiring diagram)
Controlling the EVENAIR ® through a standard ON/OFF wall
switch. This method allows for manual control of the EVENAIR ®
unit in the area desired.
W IRING M ETHOD N O .2 (See Figure 6 for wiring diagram)
Controlling the EVENAIR ® through a central heating/air
conditioning forced air system. This method allows for
automatic operation of the EVENAIR
® unit. The
EVENAIR ® is wired in parallel with the appliance blower
motor. This operates the EVENAIR ® whenever the
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 M ETHOD N O .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 ® unit is recommended for
forced central heating/air conditioning systems. Annual removal and
cleaning of the EVENAIR
® unit is recommended for gravity warm air
heating systems not equipped with a return air filter.
