TROUBLESHOOTING RESIDUAL BUILDUP AND WET OUTPUT
The following list of items may cause wet output or residue to form.
1.) Low CO2 Pressure (less than 275 p.s.i.g). Check to ensure the Pressure Builder Valve is turned on and the
pressure is over 300 p.s.i.g. before use. Monitor the pressure through the cue to see if the pressure does not
drop below 275p.s.i.g. if it does residue will begin to form.
2.) With the use of Mini Dewars this some times becomes a problem. Many Gas filling Stations do not correctly
fill the Mini Liquid CO2 Tank and may cause them not to perform as well as large Dewars. This can be
overcome by adding a High Pressure 20 pound cylinder or going to full size Dewars.
3.) The Freezefog in not connected to the Liquid side of the Liquid CO2 Tank. You must always use the Liquid
CO2 from the Liquid CO2 Tank NOT the vapour.
4.) If using ducting the duct may have a kink or some kind of obstruction in it.
5.) Fog machines nozzles are not straight out of the machine. These must be straight to ensure the fog can
fully expand. Visually check the copper tubes at the G300 output to ensure the fog is exiting the output. If they
are not, use a pair of pliers and adjust. (Be careful as they may be extremely HOT).
6.) Fog Machine is not lined up with the entry hole. This is where the G300 meets the Freezefog. If this does
not meet direct and straight the fog can not expand fully. Take a flashlight and shine it through the 10" opening
of the Freezefog and look through to the input to see if it is lined up properly.
7.) The G300 is not processing the fog properly. Remove the machine from the Freezefog, turn on the G300
and place your hand in the fog stream 24" away from the front of the machine. Your hand should be dry. You
will feel a slight warming but do not confuse this for moisture. If the machine is not performing properly your
hand will be very wet. The G300 should be serviced to rectify the problem.
8.) Too much fog is being pushed through the Freezefog. On the High Pressure Freezefog we would
recommend less than a 20 Flow Rate setting on the G300 remote on the Low Pressure Freezefog we would
recommend less than a 25 Flow Rate setting on the G300 remote.
9.) Wrong Fluid is being used. Le Maitre's Low Smoke Fluid should be the only fluid used. Longer lasting fogs
can cause this but again it is not observed often. If another manufacturer's fluid is used this will definitely cause
this type of problem.
10.) The fresh air or the air inlets on the Freezefog are obstructed. This happens some time when things get
moved around or items are placed on top of the Freezefog 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 Freezefog is installed in a very small
room and no make up air is allowed to enter causing a vacuum within the room. This is very rare, but possible.
11.) The Freezefog Valve is defective or damaged and is not allowing enough liquid CO2 into the Freezefog.
12.) The Freezefog is damaged and is not getting good air flow.
13.) The internal air expanding unit is damaged or has come dislodged from its mounting device.
If you are experiencing a residue problem, and the above checklist has failed to solve the problem, please call
Le Maitre Ltd for assistance in rectifying the problem.
