7. Caution: T o prevent electrical shock do not use
this (polarized) plug with an extension cord, receptacle or other outlet unless the blades can be
fully inserted to prevent blade exposure.
8. For added protection for this product during a
lightening storm or when it is left unattended and
unused for long periods of time, it is recommended
that you unplug the unit from the wall outlet. This
will prevent damage to the product due to lightening or power line surges.
9. Do not use attachments not recommended in this
owner’s manual as they may cause hazards.
10. Do not use the equipment near water; for example near a bathtub, washbowl, kitchen sink, a
wet basement, swimming pool, etc. This product

in this manual before operating this equipment.
2. The lightening flash within an equilateral triangle shown above is intended to alert you to the
presence of uninsulated ‘dangerous voltage’ within
the product’s enclosure that may be of sufficient
magnitude to constitute an electric shock.

Caution For Installation
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 fit, 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 con-
1
nected to this product.
3. Do not overload wall outlets, extension or integral convenience receptacles, as this could result
in a risk of fire or shock.
Operating Voltage
The C12 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.
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 CR12 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 C12 is designed to be used in
three different formats -intake/blow/exhaust air.
The required mode can be configured locally according to the cooling requirements of your system.
The C12 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 unit’s fans
are actually working.
Behind the grille front is a removable air-filter 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 C12 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 identifies 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.
Trigger In/Out 12VDC Mode
With the mode switch in the 12V position, and the
‘in’ input being used, the C12 will move into its
‘auto’ mode whenever a 6V to 15V input signal is
supplied
been reached.
Should you want to use one or more C12’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.
and the prescribed initial temperature has
Fan Auto-On Temperature
This switch enables you to pre-select one of two
temperature settings for activating the C12. 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 want to exhaust the hot air to the
outside you will need to remove the two ‘plugs’
and attach flexible tubing (supplied by Sherbourn
as Model H 12). Please see page 3 for a fuller description of this feature.
How To Configure The C12 For
Different ‘Air-Direction’ Flow
The C12 is a versatile system that enables you to
configure the direction of the airflow in many different ways according to the specific needs of your
installation. Be sure to disconnect the power sup-
ply before removing the top cover.
