ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing or servicing system, always turn off main
power to system. There may be more than 1 disconnect
switch.
! WARNING
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
This unit cannot be powered directly from blower motor
leads. Voltages can exceed 190 VAC (120v motors). Do
not wire directly to blower motor. Wiring to blower motor
will damage power supply and void warranty.
CAUTION
!
a. Ensure power has been removed from the heating and
cooling system.
b. Turn the Infinityt Air Purifier power switch off.
c. Connect the power cord to the power supply connector
(see Fig. 7).
d. Route the power cord through nearest cabinet hole and
protect with enclosed cable connector. Zip ties have
been enclosed to secure the power cord to the side of the
power supply.
e. Attach the quick connect terminals to the furnace
EAC--1 and EAC--2 spade connections. Attach the
ground ring to furnace chassis ground.
NOTE: The Infinityt Air Purifier is to be powered by 115v/60
Hz.
NOTE: The Infinityt Air Purifier should only be powered when
airflow is present. The furnace control EAC spade connections
provide power only when the furnace blower is operating. If EAC
connections are not available, an alternative airflow sensing
mechanism must be used to ensure the Infinityt Air Purifier is
only powered when airflow is present. Contact a local Carrier
distributor for information on approved alternatives.
