1. The dealership from which you purchased the product
is an expert on custom installation procedures and can
provide invaluable advice to help you make an aesthetically
pleasing and trouble free installation.
Caution For Connections
1. Connect this equipment only to the type of AC
power source as marked on the unit. Always route AC
power cords so they are not likely to be walked on, or
tripped over, or where they may be pinched by items
placed on or against them. Always pay particular attention
to cords at plugs and/or convenience receptacles, and
at the point where they exit from the product.
2. Do not defeat the inherent design features of the
polarized plug. Non-polarized line cord adapters will
defeat the safety provided by the polarized AC plug.
If the plug should fail to t, contact your electrician to
replace your obsolete outlet. Do not defeat the safety
purpose of the grounding-type plug. If you use this product
in a country which only has two slotted receptacles in
the house, you must use a three-pin adapter plug to earth
ground which is the E (earth pin) of the power cord
connected to this product.
3. Do not overload wall outlets, extension or integral
convenience receptacles, as this could result in a risk of
re or shock.
Operating Voltage
The Fan System is factory-set for 110V, 120V or 230V AC
operation at either 50 or 60 Hz, according to the
country for which the unit was manufactured (230V
in European Union countries, in compliance with CE
regulations). The operating voltage cannot be changed
by the user and any attempt to do so will void the warranty.

Trigger In/Out 12VDC Mode
With the mode switch in the 12V position, and the in
input being used, the RKF-100 will move into its auto
mode whenever a 6V to 15V input signal is supplied
and the prescribed initial temperature has been reached.
Should you want to use one or more RKF-100
s within the
same location you can synchronize the units by using
the sync switch. For this situation you should use the
out jack from one unit (which then becomes the master)
and go into the in jack for the second unit (which then
becomes the slave). The two units will now be in sync
and will start to work in unison once the prescribed
initial temperature of the master unit has been reached.
Note that in this type of multi-unit installation all of the
internal temperature sensors of the slave units are defeated.
Fan Auto-On Temperature
This switch enables you to pre-select one of two temperature
settings for activating the RKF-100. The low setting is 95
degrees Fahrenheit (35 degree Celsius) and the high
setting is 104 degrees Fahrenheit (40 degrees Celsius).
This important feature ensures that the fans only work
above the selected ambient temperature.
If you want to exhaust the hot air to the outside you will
need to remove the two plugs and attach exible tubing
(not included with the unit). Please see page 4 for a
fuller description of this feature.
Fill out and send in the owners registration card packed with
the RKF-100. Also be sure to keep the original sales receipt.
It is your best record of the date of purchase, which you will
need in the event warranty service is ever required.
Care of the Product
Clean the product by dusting with a dry cloth. Do not
permit objects of any kind to be pushed and/or fall into
the product through the enclosure openings.
General Description
The RKF-100 is a multi-directional fan system that uses three
4.75-inch (120 mm) whisper quiet fans, the speeds of
which are governed by thermal sensing circuitry. The
RKF-100 is designed to be used in three different formats
-intake/blow/exhaust air. The required mode can be
con gured locally according to the cooling requirements
of your system.
The RKF-100 has many other features and functions that
are all described in the following pages.
Front Panel Description
The (removable) rack mountable front panel houses a switch
for controlling the on/off and auto functions. A blue LED
indicates when the units fans are actually working.
Behind the grille front is a removable air- lter pad.
It is important to note that the only time the switch
needs to be in the on position is during an initial
test when the fans will be operating at their
maximum speed. Once the RKF-100 has completed
its test, it is recommended that the switch be
placed in its auto position. In this mode neither
the fans nor the LED will operate until the selected
ambient temperature is reached.
Rear Panel Description
The following description identi es each of the main controls
/connections and follows the rear panel from left to right.
Temperature Sensor
This input enables you to connect the (supplied) pigtail
sensing cord. The magnetized head should be placed
on the hot spot of your installation whereupon it will
measure the ambient temperature, which in turn will govern
the speed of the three fans.
Please note that there is also an in-built sensing device
located on the underside of the chassis that is by-passed
if the pigtail sensor is used. If the pigtail sensor is not
used, then the in-built sensor will automatically activate
once the selected minimum temperature has been reached.
