DANGER!
Risk of asphyxiation!
Carbon dioxide can cause asphyxiation. Ensure that the work space has adequate ventilation. Do not
place the system in an enclosed area. The iCELLis 500+ control system can deliver carbon dioxide up to
1.5 L/min. Carbon dioxide supply to the iCELLis 500+ controller is the user’s responsibility.
DANGER!
Risk of asphyxiation!
Nitrogen can cause asphyxiation. Ensure that the work space has adequate ventilation. Do not place the
system in an enclosed area. Note that the iCELLis 500+ control system can supply nitrogen up to 1.5
L/min. Nitrogen supply to the iCELLis 500+ control system is the user’s responsibility.
WARNING!
Risk of injury to personnel and/or damage to equipment!
Gases supplied to the iCELLis 500+ control system must be regulated to specified pressure (maximum 2.5
barg or 36.3 PSIG) and must be oil-free, dry and clean. To prevent possible system component damage,
do not exceed these recommendations. Each gas line should be supplied with an ON/OFF valve and an
independent pressure regulator.
All materials in contact with the 4 gases are made of stainless steel or USP <88> Class VI material.
Figure 28: Gas supply inlets of iCELLis 500+ control system
Gas input ports are located on the rear panel of the iCELLis 500+ control system (Figure 28).
Connect external gas supply lines to the iCELLis 500+ control system using the Swagelock ¼ in. OD
tube fittings. The 4 gas input connectors on the machine are Swagelock bulkhead unions (SS-400-61)
and are delivered with the system (Figure 29). The gas supply lines shall be compatible with the input
connectors.

Optimal gas delivery pressure to the controller gas inlets are between 2 and 2.5 barg (25 and 36.3
psig). Do not allow gas pressure to exceed 2.5 barg (36.3 psig). A means of independently monitoring
of gases close to the equipment is recommended to prevent the risk of a gas leakage.
Use of 0.2 to 0.45 µm filters between the gas delivery end-point and the iCELLis 500+ control system
inlets is highly recommended to prevent mass flow controllers’ damage by dust particles. Contact your
Pall representative for appropriate references.
