INSTALLATION
INSTRUCTIONS FOR KTA SYSTEM FAN POWER SUPPLY/INDICATOR PANEL WITH MATCHING
24-VOLT AC FAN
 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.
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.

Instructions for
Installation:
DO NOT PLUG IN POWER
SUPPLY UNTIL ALL STEPS ARE COMPLETED.
1.
Installation of the fan in the system:
The fan should always be
installed vertically to prevent condensation from accumulating in the fan
housing. If attached ductwork will convey moist air and the ductwork passes
through cool areas or outside, provisions should be made for the prevention
of condensate accumulation in the ductwork. This may be accomplished by
insulating the ductwork and installing a water separation device such as a KT
Hydro-Sep™. Non-adherence to these provisions may affect the life expectancy
of this product and will void manufacturer’s warranties. The fan may be
located inside or outside a building, but not in a hazardous environment.
Flexible PVC pipe-to-fan inlet or outlet adapters are available for ease of
installation and for noise attenuation. The fan and associated ductwork
should be secured so that the ductwork does not enter the fan housing and
cause damage.
2.
Mounting the KTA box:
- The KTA box is designed to
be mounted in an INTERIOR, NON-HAZARDOUS location only.
- The KTA box should be
located so that the 6 ft. grounded power cord can easily reach a 120
volt grounded receptacle.
- The KTA box should be
located in an area where the indicator can be easily seen and
periodically monitored.
The KTA box should be
within 50 feet of fan. A maximum of 50 feet of cable is provided with the KTA
box. Do not extend low voltage power cable beyond 50 feet, or cut cable less
than 10 feet. A mounting template and 2 mounting screws for the KTA box are
included in the envelope. The template provides the correct 4 7/8 inch
spacing for the mounting screws for the KTA box. Use the template to position
the screws on the wall or fasten the foam template to the wall to let it
function as a pad. Do not tighten the screws fully into the wall. Allow room
for the keyholes on the backside of the KTA box to slide over the screw
heads.
Mount KTA box on screws
by placing keyholes in brackets at back of box over screws and pulling down.
if box is not firmly seated on screws, remove box and turn screws further
into wall.
3.
Routing cable from Fan to KTA Box
Either 25 or 50 feet of
two conductor cable is supplied as part of the packaged system. This cable is
to be used to supply the low voltage power to the fan. One end has a quick
connect cable attached to it - this end is to be connected to the panel
mounted socket on the side of the fan.
Route the cable from the
fan to the location where the KTA box is to be located. Support cable with
tie-wrap fasteners, cable fasteners, or within conduit, depending upon
building type and local code requirements. Do not use metal staples to secure
cable. if mounting brackets are to be used for cable, use clip types that are
suitable for securing television or VCR coaxial cable, such as GC Electronics
#H7. Do not bury cable. The cable supplied with the unit is suitable for
indoor and outdoor routings. After the cable has been routed to the KTA box
cut the excess cable with a pair of wire cutters (it is advisable to leave
some extra cable that would allow the KTA box to be set on a table or the
floor to allow for easier connection of the cable.)
4.
Connecting Wire to KTA Box
Before connecting the
wire to the KTA box make sure that the box is not plugged in and the switch
on the side of the box is OFF.
After cutting off any
excess cable, remove 2 inches of the cable jacket from the end of the cable.
Be careful not to strip the insulation from the two wires inside of the cable
jacket. Remove the foil wrap around the two exposed wires (if an un-insulated
wire strand is inside the cable, cut this unnecessary wire at the point it is
exposed at the jacket).
Strip ¼ inch of the
insulation from the two exposed wires.
Loosen the nut on the
strain relief attached to the terminal block cover.
Remove the terminal
block cover on the bottom of the KTA box by unscrewing the four sheet metal
screws that hold it in place.
Thread the cable through
the strain relief. Insert the bared ends of the two wires of the cable into
either one of the slots on the terminal block and secure by tightening the
screws in each slot. Slide the terminal block cover into place and secure
with four sheet metal screws. Tighten nut on strain relief securely to jacket
of cable.
5.
Fan Wiring:
Push cable connector end
over pins of socket on side of fan. There is an alignment guide within the
two connectors. Slide the locking ring on the cable side of the connector
over the fan socket and rotate to the right until it snaps into place.
6.
Indicator Adjustment
After final installation
of system ductwork, fan, power supply, and wiring, the system should be ready
to turn on. Plug in the 6 foot electrical cord directly into a 120 volt AC
wall socket, and turn on the switch on the right side of the KTA box.
When the fan is energized,
the needle of the indicator on the face of the KTA box will move to the
right. After the fan has come up to speed (30 seconds), and the system has
come to equilibrium, the needle should be adjusted so that it is centered on
the line saying “Initial Installation” located on the face of the meter. The
needle is adjusted by rotating the screw on the face of the meter with a
screwdriver. Look at the needle after adjustment to make sure that any
magnetism in the screwdriver has not affected the needle position. If so,
readjust until the needle is centered when the screwdriver is removed.
Deviations in the airflow of the system will cause the needle to move to
either side of the centerline of the indicator, which will alert the building
occupant to a potential problem.
It is important to note
that the system should be fully installed prior to indicator adjustment. If
modifications are made to the system that would affect the “normal” system
airflow, the meter can be re-adjusted as described above. To prevent
unauthorized adjustment of the needle position, a black paper, self adhesive
dot has been provided in the envelope to cover the adjustment screw. A second
dot has been provided for future adjustments.
7.
Documentation:
A space has been
provided on the front panel of the KTA box for placing a label which includes
system identification, the installer’s name and a phone number. The installer
should leave a description of the system installed along with any appropriate
warranty and maintenance information with the client. The KTA system has the
unique feature of an easy to read indicator that shows when the amount of air
going through the fan has changed from the time of the original installation.
The interpretation of this indicator is summarized in the trouble-shooting
guide that follows. This guide should be left with the homeowner.
READ AND SAVE THESE INSTRUCTIONS
KTA
- Fan & Power Supply/Indicator Trouble Shooting Guide
If the Indicator
needle moves to the right of center “Initial Installation Line”:
This is caused when more
air is being handled by the fan than it did when it was originally installed.
Check for leaks in the ductwork system.
If Indicator needle
moves to the left of center “Initial Installation Line”:
This is caused by less
air being handled by the fan than it did when it was originally installed
- Check for any restrictions
to air flow in the suction and discharge ductwork
- Check for obstructions in
the fan ( see Safety Caution below).
If Indicator needle
is far to the left and not moving:
This is caused by a
disruption in the power to the fan:
- Check to see that KTA box is
plugged into The 120 volt receptacle.
- Check the switch on side of
the KTA box. This is a combination switch and circuit breaker. If this
is in the OFF position this could be caused by unintentional turning off
of the system, or a current overload situation has occurred. Reset the
breaker by turning the switch to ON. If the switch flips immediately to
the OFF position, unplug the unit and call the installer for service. If
the switch flips to the OFF position, after a few minutes, unplug the
KTA box, and disconnect the cable at the fan. Remove and inspect the fan
for obstructions such as debris or ice. If ice is entering the fan
contact the installer about installing a Hydro-Sep TM device.
- Check wiring between the KTA
box and the fan. If broken, contact installer.
- Check the fan to see if it
is turning. if not, the fan may be non-functional Contact the installer
or manufacturer. If the system is to be removed for warranty repairs,
disconnect both the KTA box and the KTA-I50 fan. Both the KTA power
supply box and the KTA-150 fan, along with the cable, are to be returned
to the manufacturer as a unit. Call for a return authorization number.
SAFETY CAUTION: Before
servicing or removing fan, disconnect cable at fan. Read safety instructions
above.
