4.
Position the unit on a bench where it has at least 6" (15.24 cm) clearance from
the back of the unit to the wall, bench or other obstruction. The cooling fan on
the rear of the unit needs to draw air clearly to cool the Peltier unit. Also, there
must be about 3" (7.62 cm) clearance on either side of the unit and 6” (15.24 cm)
on top of the unit to allow proper venting.
5.
Place the wire racks provided into the slots selected.
6.
Turn the unit on by the main On/Off switch on the rear panel. The LCD on the
front panel will illuminate and be in the temperature/timer display mode. The
fans on the rear panel and inside the instrument chamber will start to run. The
instrument is now ready to use.
VI. GENERAL DESCRIPTION
The Torrey Pines Scientific Chilling Incubators are digitally controlled and Peltier driven.
Because they are Peltier driven, they have no CFC’s or other refrigerating gases. Also,
being Peltier driven, the units have the ability to heat and cool
and control exactly at
or near ambient room temperature.
The units can hold temperatures accurately, and
reproduce temperatures exactly. The chamber is molded ABS plastic and the racks are
electro-polished steel.
Since the units are Peltier driven there is a fan in the chamber and one on the rear of
the units. The internal fan is used to keep the chamber at a uniform temperature
throughout. There is an inner chamber door of clear lexan to help hold the chamber
temperature while viewing the sample.
Temperature is sensed by a microchip inside the chamber. The settable temperature
range is from 4.0ºC to 70.0ºC. The unit has a membrane keypad with tactile touch and
audible feedback for setting temperature, temperature ramp, timer, auto-off, and three
programs of ten steps each.
The timer is in days, hours, minutes and seconds. The timer can be set to 99:59:59:59
days, hours, minutes, and seconds maximum. When the timer counts to zero it will
sound the audible alarm for one minute and the timer will start to count up. The unit can
be set to turn off the heater/chiller at the end of a timed event by using the AUTO-OFF
function.
The IN35 and IN45 are supplied with an RS232 port for recording temperature data at
one data point per second. More information is available on this in a later chapter.
