Refer to the Material Safety Data Sheet (MSDS) supplied with each chemical and adhere to all safety precautions recommended by the manufacturer.
Set-upet Electrical Requirements The ThermoFlo unit draws 700 Watts, which is listed on the nameplate on the power source rear panel. A separate, dedicated AC supply line circuit may be required to adequately power the unit/system. If your power outlet cannot provide suitable power, arrange for a qualified, licensed electrician to install one for you. System Set-up Set up the ThermoFlo unit using the following steps and associated drawings.
Set-up ANGLE BRACKET KIT The Angle Bracket Kit elevates the front of the power source to allow easier viewing and access to the front panel controls. Attach the kit to the ThermoFlo power source using the following instructions. 1. Turn the power source upside down on the work bench with the front panel facing away from you.
Set-up THERMOFLO CUBBY KIT The ThermoFlo Cubby Kit can be attached to either side of the power source. To attach the ThermoFlo Cubby Kit (handpiece holder) to the power source, use the following instructions. 1. Position the Holder as shown with the curved wire ends directly beneath the mounting holes in the Cubby Bracket.

Operation Profile - An established procedure for rework which includes all parameters (e.g., operating temperature, cycle time, preheat) required for optimum rework of a particular component/pcb combination. Any established Profile can then be utilized by entering it into system memory; the Profile can then be easily recalled and used in the system Program Mode.
Operation Nozzle Selection Selection of the proper Nozzle is essential for achieving a quality component removal or installation. Each ThermoFlo Nozzle is designed to properly direct the heated air. The Replacement Parts section of this manual lists standard nozzles and the components for which they are normally used.
Operation Template Selection Alignment Templates are used as an aid in aligning V-A-N Nozzles to the PCB Assembly when installing Ball Grid Arrays (BGAs). The I.D. (Inside Dimension) of the template should match the perimeter of the BGA land pattern. Figure 19.
Operation Nozzle Changeout REMOVAL WARNING Never remove a heated Nozzle using bare hands. Use the Rubber Pad. Never use a wrench or pliers when removing a Nozzle. 1. Holding the Rubber Pad, gently twist the nozzle as shown. The Nozzle will easily release from the Nozzle Adapter.
Operation Manual Mode of Operation MANUAL MODE COMPONENT REMOVAL 1. Install the proper Nozzle Assembly and Vacuum Cup onto the handpiece.

Operation Program Mode The Program Mode of operation (Program Mode Light illuminated) utilizes user developed rework profiles previously stored in memory. The user recalls and uses the stored profile to produce consistent, repeatable results. Four profile stages can be programmed: preheat, soak, reflow and cool down. This allows you to emulate the production process.
