Installation And Setup - LEEC GA2000 Operating Instructions Manual

2.0 INSTALLATION AND SET UP
2.1 Your LEEC CO2 incubator must be installed in suitable location. It should be placed
on a firm flat surface such as a laboratory bench, LEEC stacking frame or the floor.
All models have adjustable feet at the front. An adjustable spanner is required if the
feet need adjusting. A spirit level should be used to check for level.
2.2 Do not locate the incubator in direct sunlight or near heat sources.
LEEC CO2 incubators use Carbon Dioxide gas, which can be harmful to
your health. It is important to provide sufficient ventilation to ensure that the
gas flowing out of the side ports is not allowed to build up in the laboratory
or room where the incubator is located.
2.3 ELECTRICAL
LEEC CO2 incubators should only be connected to a 240V AC, 50Hz power outlet.
A UK 3-pin moulded plug and power cable is fitted as standard. The wiring colour
inside the power cable is as follows:
BROWN
•
BLUE
•
GREEN/YELLOW
•
2.4 CO2 GAS SUPPLY
The CO2 gas inlet nozzle is located at the back right hand corner. Ordinary
commercial CO2 gas should be used at 1 p.s.i. (0.06 bar). Never use liquid CO2
cylinders. LEEC can supply suitable pressure reducing valves with a 0-30 p.s.i.
downstream gauge, to reduce the gas pressure to the correct level. Connect the
incubator to the CO2 supply using clear plastic tubing. Rubber hose or the use of
jubilee clips is not recommended.
It is important that the incoming CO2 supply pressure is 1 p.s.i.
Higher pressure than this will cause the CO2 control system to
overshoot. Excessive pressure (i.e. over 120 p.s.i. / 8.0 bar) could
damage the incubators sensitive Infrared CO2 detector system.
2.5 START UP
Check that the power cable and CO2 connection has been connected correctly.
Turn the incubator ON by pressing the green Power On button. The green button
will illuminate when the power is switched on. All display elements will light up,
perform a self test and the display will show LEEC 20.2.
