LINDERS These instructions are given for systems using a Le Maitre Freezefog enabled smoke machine with Freezefog Control Option Alternate control options are given further in this manual 1 Place the smoke machine output directly against the input of the Freezefog Pro Technical Tip Proper alignment can be observed by shining a torch into the 10 exit of the Freezefog Pro and noting the smoke machine output nozzle is centered in the Freezefog input 2 Connect the blue Twist lock connector from the Freezefog into the custom port on the rear panel of the smoke machine 3 Power up the smoke machine by turning on the Mains switch Note if using a G300 Ensure that the G300 is in G300 mode which is indicated by a flashing G in the Ready Flash window of the remote display To switch into G Mode 4 Adjust remote interval control dial fully clockwise until DEL appears on the display 5 Adjust remote duration control dial until desired delay is displayed up to 30 seconds Note This delay allows the liquid CO2 to purge the supply hose of CO2 gases ensuring only liquid is available for optimum cooling The recommended formula for calculating delay time is 1 sec for every three feet of supply hose MODE Heat Ready Flash FlowRate clash pi SMOKE OFF Minutes Seconds INTERVAL DURATION FLOW RATE SMOKE ON G300 Remote Interface 6 Adjust the remote flow rate to des

V 02 01 08 Le Maitre s Freezefog Pro OPERATOR S MANUAL ITECHNICS amp SI Freezefog Pro www lemaitreltd com INTRODUCTION Le Maitre Freezefog Overview The Freezefog needs a liquid CO2 supply Either high or low pressure although better results are obtained with low pressure The Freezefog Pro requires a Le Maitre smoke machine that is Freezefog enabled This is found in the G300 Any other machine will have to be specially adapted The smoke machines require Low Smoke fluid You must ONLY use this as it is designed to bond with the CO2 on a molecular level CO2 is a colourless odourless gas It is only seen when the refraction density is altered In the past water was used with solid CO2 which worked well but tended to leave the area damp and slippery The Freezefog works by adding Low Smoke fluid from the smoke machine to the liquid CO2 injected into the Freezefog The result is proper Dry Ice Low Smoke The only difference being there is no dampness associated with the effect The unique partnering of a fog effect with liquid C02 is cost effective and provides a longer lasting effect Designed to be utilised with the Freezefog Pro the Le Maitre Low Smoke Fluid provides a dry thick white effect with a consistent dissipation that eliminates any ambient hazing The Freezefog couples with the Le Maitre smoke machine offering the most advanced controls and fog output available The Freezefog consumes approximately 3 5 kilos

8. make sure the sum of all cross sectional areas of the final duct sizes is equivalent or greater than the cross sectional area of the Freezefog 10 outlet Doing this will prevent any backpressure being created by the Freezefog The formula for cross sectional area 0 78539 x diameter squared Example The Freezefog outlet has a diameter of 10 0 78539 x 100 78 5 square inches is the area of the Freezefog outlet If you require 3 locations to duct the effect to then the cross sectional area of the 3 ducts must be greater than 78 5 square inches For this example we will try a 6 diameter duct 0 78539 x 36 28 lf we multiply the cross sectional area of the 6 duct by 3 duct outlets 28 x 3 84 84 is greater than 78 5 so the 6 ducting split into 3 ducts is acceptable Some form of dampering may have to be used to balance the output of different sized outputs www lemaitreltd com 4 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 ma
