INSTALLATION INSTRUCTIONS FOR KTA SYSTEM FAN POWER SUPPLY/INDICATOR
PANEL WITH MATCHING 24-VOLT AC FAN
THE PHYSIOLOGICAL EFFECTS REGARDING THE END USE APPLICATION OF THIS PRODUCT CANNOT BE
DETERMINED, SINCE IT IS INTEGRAL TO A SYSTEM TO BE INSTALL BY OTHERS.
The KTA is provided as a matched set consisting of a fan and a power supply/indicator panel. The two units are to
be installed as a matched set. The use of this power supply or fan, in conjunction with any other fan or means of
power, respectively; may be hazardous and will void all warranties. See installation precautions on the following
page. The two matched components are as follows:
POWER SUPPLY/INDICATOR BOX (KTA Box): This is a wall mounted power supply for placement in non-hazardous
environments. It receives power from a 120 volt power receptacle via the 6 foot grounded plug-in cord attached to
the bottom of the box. The unit provides a 24-volt output for power to a matching 24 volt, input fan. It also has an
analog indicator that is proportional to the airflow of the system.
KT-150 TURBINE FAN: This is a high efficiency 24-volt input, 1/20 hp., in-line fan. It is rated for placement in non-
hazardous indoor or outdoor locations. The fan is nominally rated for 270 cubic feet per minute of air with no
restrictions. Actual fan performance will depend upon the restrictions imposed by the duct or piping system. Its
bearings are sealed thus eliminating routine maintenance.
Installation and Use Precautions:
Should you have any questions on the safe installation or use of this system contact the manufacturer at (719) 444-
0646.
WARNING—TO REDUCE THE RISK OF ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING: The
following precautions should be followed The output of the power supply panel to the fan falls under Article 725 of
the National Electric Code for Class 2 power limited circuits.
Use this unit only in the manner intended by the manufacturer if you have questions, contact the
manufacturer.
Neither the KTA power supply box nor the fan have any user serviceable components. However, it may be
necessary to remove the fan from its system to remove debris. In this case, the following precautions for
safe disconnection of the system are to be followed.
Before servicing or removing the fan, flip the switch on the right side of the KTA Box to OFF, disconnect the
power from KTA box by unplugging the KTA from receptacle. Disconnect the cable at the FAN by twisting the
cable connector on the side of the Fan ¼ turn to the left and pulling connector from the socket.
After servicing the fan, reattach the cable to the side of the fan by plugging the cable connector into side of
the FAN and twisting the cable connector collar ¼ turn to the right until it snaps tight. Plug the KTA box
back into the wall receptacle and turn the switch on the side of the KTA box to ON.
Do not reinstall he fan in any manner that will alter the disconnect devices. To avoid physical injury, do not
handle the fan while it is operating
CAUTION THIS FAN IS FOR GENERAL VENTILATING USE ONLY. DO NOT USE TO EXHAUST HAZARDOUS OR

Description of System:
The system consists of one (1) Power Supply/Indicator Box and
one (1) matching 24 volt fan. This system is typically used in
applications where low voltage Class 2 wiring from the power
supply to a remotely located fan is advantageous. It is also
used in applications where it is desirous to have an indication
as to whether the fan is still performing in the manner in
which it was originally installed. The KTA system provides both
of these features.
The KTA Fan system is designed to be a part of a ventilation,
depressurization, or exhaust system where non-explosive or
non-flammable air mixtures will be encountered. The
manufacturer cannot make any representations as to the
entire system of which the KTA and fan are integral parts,
since they are designed and installed by others.
