ADAPTERS: (Set of two): These
extend the width of any 19-inch [482.6mm] Packaged Blower, Packaged Fan or Rack-Mounted
Air Conditioner to permit mounting in a cabinet designed for 24-inch [609.6mm] units.
The EIA-notched adapters are covered by a plate of mirror-finish stainless steel
to match Kooltronic Standard Grilles.
These adapters are non-structural. Therefore, Packaged Blowers and Rack-Mounted
Air Conditioners must be supported at the rear, due to their weight.
Dimensions, inches [mm], are for reference only and subject to change.
The built-in airflow switch option protects equipment against damage caused by
loss of cooling airflow by activating a customer supplied alarm or turning off
power. The switch is factory mounted on a suitable surface, which allows the
stainless steel air vane to be placed in the critical airstream. This switch is a single-pole double throw type, with normally open and normally
closed contacts. Airflow switch connections: White = Common. Black =
N.O. Red = N.C. Add suffix - XX10 to part number to specify this option.
The UL rating for the rotary snap action switch is 5 amps at 250 volts AC. A three
foot [0.9m], three wire power cord is provided, allowing connection to normally
open or normally closed circuits.
The choice of air vanes is determined by location and orientation in the airstream,
and the normal operating air velocity at the point of installation. Refer to the
chart below or consult Kooltronic Engineering for assistance.

AUTOMATIC SPEED CONTROL: The Kooltronic Fan and Blower Automatic Speed
Control (Part Number KSC100) is a solid state "smart" controller packaged in a
NEMA 1 type enclosure for remote mounting. The allowable input power supply
range is 95 to 250 Volts, 47 to 63 Hz. It is furnished standard with an IEC 320
connector, a power supply fuse and a temperature sensor. Additional temperature
sensors are optional.
Power Cord is not provided.
The controller will operate single or multiple fans or blowers of compatible
voltage and frequency up to a combined load of 6 Amps. The controller may be
operated by either a control voltage signal of 0 to 10 VDC, a control current
signal of 0 to 20 mA or one to three temperature sensors. With multiple
temperature sensors the controller will respond to the highest sensed
The control circuit board is furnished with a terminal strip for field
connecting the sensor and fan wires. A pressure type strain relief connector is
furnished in the enclosure. If required by the installation or by code, this
connector can be replaced with a 1/2-inch [12.7mm] trade size conduit connector.
A wide variety of control logic options can be field programmed into the
controller by means of a board mounted DIP switch. These include fan idle or
starting speed at 30%, 40%, 50% or 60% of supply voltage, fan on or off below
the idle setting, control temperature setting of 86ºF (30ºC), 95ºF (35ºC), 104ºF
(40ºC), 113ºF (45ºC), and temperature differential settings of 7ºF (4ºC) and
18ºF (10ºC). The selectable fan on/off feature is operative when the
temperature(s) drop below the control temperature setting.
Consult factory for use with compatible Kooltronic fans or blowers.
