8. Too much fog is being pushed through the LSG Mark II. On the High Pressure LSG Mark II we would
recommend less then a 20 Flow Rate setting on the fog machine remote on the Low Pressure LSG Mark II we
would recommend Less then a 25 Flow Rate setting on the fog machine remote.
9. Wrong Fluid is being used. Ultratec Special Effects Molecular should be the only uid used. Longer lasting fogs
can cause this but again it is not observed often. If another manufacturers uid is used this will denitely cause
this type of problem.
10. The fresh air or the air inlets on the LSG Mark II are obstructed. This happens sometimes when things get
moved around or items are placed on top of the LSG Mark II and drape over the inlet holes. Or the unit is
placed too close to a wall or another piece of equipment. It can also happen if the LSG Mark II is installed in
a very small room and no make up air is allowed to enter causing a vacuum within the room. This is also very
rare but possible.
11. The LSG Mark II Valve is defective or damaged and is not allowing enough Liquid CO2 into the LSG Mark II.
12. The LSG Mark II is damaged and is not getting good air ow.
13. The internal air expanding unit is damaged or has come dislodged from it’s mounting device.
