Instruction Manual - G85

If the use necessitates low recovery times, either a constant high flow must be used or
purging the chambers by setting the flow level at a high rate for 2-3 minutes.
A flow of 10 l/h will be sufficient to sustain the CO
2
levels in the chambers when the lids
are not opened. The flow rate should at no time be kept under 8 l/h.
A flow rate of 15-20 l/h should be adequate under most conditions without the use of
manual purge.
5.7.3 Humidifying the gas mixture
In order to avoid Gassing with cold and dry Gas, the built in humidifier can be used.
Connect the tubes as show on the picture below.
Warning Always route the gas as shown or permanent damage to the airflow sensors
may occur.
If the humidification system is not used and the gassing is done with dry gas, a silicone
tube U loop must be connected between the outlet and inlet for the humidification bottle.
K-SYSTEMS have experienced a quantity of failures on the flow sensors due to liquid
entering the sensor and damaging it.
The fault is registered by the user getting a “0” reading in the display, when an obvious
flow can be seen as bubbles in the humidification flask.
When adjustment in the flow rate is done on the regulator valve on the side of the G85, no
changes can be seen to the flow reading in the display. It will stay at “0” disregarding the
flow.
