1.0 INTRODUCTION: 1.1
The SafeAir Heatstream: The SafeAir Heatstream is a portable, light, quiet and reliable heating source for use in the preparation and fitting of removable and fixed prosthodontics, in dental surgeries, dental hospitals or for home visits. The SafeAir Heatstream is designed for softening and melting dental wax and thermoplastic impression materials used in the preparation of custom registration trays and registration blocks. In addition, it can be used for heating modelling tools and rim formers when working on the wax form. Do not insert into the hot air outlet (see Section 3.1 Operator safety). The SafeAir Heatstream uses a hot air heating system and therefore avoids the potential risks of setting fire to latex, neoprene or vinyl gloves when using other heating methods. The SafeAir Heatstream comes with a catch tray that is used for containing any drips and spillages from the heating process. In addition, the catch tray defines the safe working area of the SafeAir Heatstream. It is safety interlocked and must be fitted for the SafeAir to operate The catch tray and its insert can be removed for cleaning and storage.

2.0 INSTALLATION AND SAFETY: 2.1
Unpacking & handling the SafeAir Heatstream Remove the unit from the storage case, and check that no packing material remains inside the nozzle. Do not connect the unit to the electrical supply while it is in its case or while it is inside any other container. Do not place it in its storage or any other container while the unit is still hot. Always lift or move the unit by the SafeAir Heatstream main body with one hand and support the catch tray with the other. Do not lift or move by holding the tray only. Do not lift it by the supply cable or by the nozzle.
2.2
Siting & setting up the SafeAir Heatstream Place the unit in a well ventilated area, on a work bench or table, in an upright position. Be aware that the process the unit is used for could trigger nearby smoke alarms. Note: that although all SafeAirs are tested, before packing, on a short heating cycle; when it is first turned on a small amount of smoke and a slight burning smell may be noticed, as organic binders and dust are burned out of the insulation material and from the element. Keep the unit away from water or other liquids. Do not place near inflammable materials. Position the unit at a safe distance from other objects. At least 150mm distance is recommended. Position the SafeAir so that the mains electrical switch and plug can be easily accessed in the event of a fault occurring When in use, the nozzle should face away from the operator and from other people in the vicinity.
2.3
Warning symbols: WARNING. When the SafeAir Heatstream is switched on the hot air exit nozzle gets hot, DO NOT touch

SafeAir Heatstream 2.4
Electrical connections The unit is designed for a 220V to 240V AC single-phase live, neutral and earth supply. The SafeAir Heatstream is fitted with a lead and standard domestic 3-pin plug, fused at 5 Amps. Replacement of the plug or fuse should not be necessary, but if required should only be undertaken by an electrician or suitably qualified person. It is advisable to connect the unit to the electrical supply through an RCD safety device.
2.5
Disconnection from the electrical supply in the event of a fault The SafeAir is protected by an internal self-resetting thermal cut-out device which operates by cutting power to the elements if it overheats or a fault occurs. In the event of the thermal cut-out device operating or a fault occurring, switch the SafeAir off at the mains electrical supply and unplug. See back page for details on contacting Carbolite Engineering Services.
3.0 OPERATION: 3.1
Operator safety The operator should read this manual and observe all the recommendations in it. Do not open the unit, insert anything into it, or allow fluids to enter it. Do not operate the unit with wet hands. The SafeAir Heatstream contains a live electrical heating element operating at mains voltage. IN ORDER TO GUARD AGAINST ELECTRICAL SHOCK DO NOT INSERT TOOLS OR PROBES INTO THE HOT AIR OUTLET. Doing so presents the risk of irreparable damage to the Heatstream and could result in electrical shock. The SafeAir Heatstream produces a very high temperature air jet. Avoid burns caused by touching the nozzle or holding a hand in the hot air stream. Be careful even when wearing gloves, as burns can be caused by delayed heat transfer through a glove. Do not direct the airflow directly towards anyone. Do not use the SafeAir Heatstream in the presence of potentially explosive vapours, gases, dust, or use near volatile materials. Always use in the upright position sited on a table or work bench Never pick up and use in the hand The SafeAir Heatstream should only be used for the purposes specified in this manual. Using for purposes not specified in the manual (see Section 1.1) or for which it was not designed may present the risk of personal injury. DO NOT: DO NOT INSERT TOOLS OR OBJECTS OF ANY KIND INTO THE HOT AIR OUTLET! DO NOT DROP IT !
DO NOT IMMERSE IT IN LIQUID !
DO NOT HANDLE WITH WET GLOVES OR HANDS ! DO NOT OPERATE IN THE PRESENCE OF INFLAMMABLE VAPOURS GASES OR POWDER ! DO NOT DROP MOLTEN WAX INTO THE ON / OFF SWITCH ! DO NOT ALLOW THE CATCH TRAY TO OVERFLOW BEFORE IT IS CLEARED !

Fitting the catch tray: Before the SafeAir Heatstream can be used it must be assembled. Clip the catch tray in to the SafeAir body; this requires the SafeAir to be held upside down, the tray is then clipped in the SafeAir body using first a downward movement followed by a slide action into the SafeAir body to engage the Clip. (See Figure .) Fit the stainless steel catch tray insert after the tray has been clipped in. Note the unit will not work unless it is clipped into the catch tray for safety reasons. WARNING – DO NOT override the safety switch and operate without the catch tray 1 Downward movement and slide action into SafeAir Body

SafeAir Heatstream Light weight ceramic fibre insulation can easily be marked by accidental contact. Some fine cracks may be visible on the surface of the insulation, or may develop in the surface of the chamber due to the progressive shrinkage of the insulation materials. Cracks are not usually detrimental to the functioning or the safety of the furnace.
4.0 MAINTENANCE: 4.1
General maintenance Do not open the unit or attempt repair. There are no user serviceable parts inside the SafeAir Heatstream, if a repair is required please contact Carbolite Engineering Services: contact details are at the end of this manual.
