1. CHILDREN AND NEVER LEAVE IT UNATTENDED IN WORK DANGER This is an electrical high temperature equipment always follow all health and safety rules and regulations for this equipment in your country MADE IN UK2. process done correct Spare standard graphite crucibles and a graphite protection liquid paint are available at any time from your agent or manufacturer Never take hot graphite crucible by hand when lifting it up from its hole Pic 3 For this purpose use only stainless steel tongs that are supplied with the kiln FIRST TIME USE IMPORTANT When using this kiln for the first time please heat it up for approximately 3 5 minutes to allow water to evaporate from the chamber and from inside of the kiln slight odour and light smoke may be visible but this is normal Otherwise there is a risk of causing small cracks on the top of the chamber Let the kiln cool down before you start to work If this kiln is to be used for less than once per month please repeat this process each time before use NOTE To avoid problems with the heating element this digital temperature controller Pic 1 is pre settled by the manufacturer to a high temperature of 1130 C 2066 F You can set a higher temperature manually for example to see on the screen 1300 C 2372 F but however the controller will still heat your kiln up only to 1130 C 2066 F or less depending of your setting HOW TO FIX UNFIX CRUCIBLE IN THE KILN Pic 5 100 OZ GRAPHITE CRUCIBLE BACK VIEW Use this option if you do not want to move Crucible with molten metals to a mould by tongs Please read page 2 for more info TWO HOLDER s FIXING SCREWS WORK WITH TEMPERATURE CONTROLL
3. 1 R9D 100 ELECTRICAL METAL MELTING KILN USER MANUAL PRODUCT INTRODUCTION This digitally controlled electrical metal melting kiln is especially designed to melt down up to 100 OZ 3100 Gram of PURE gold or any other metal with a CASTING point below 1100 C 2012 F such as lead aluminium copper brass bronze tin silver gold and their alloys The R9D 100 kiln has a standard digital temperature controller and can reach and hold any single temperature between 20 C 68 F and 1130 C 2066 F once settled It means that when this kiln is connected to a power supply and is switched on it will start to heat up gradually without stopping until a pre settled temperature will be reached The kiln is able to hold the required temperature until you will pre set a different temperature or switch it off The empty kiln reaches the temperature of 1130 C 2066 F approximately in 60 90 minutes depending of the quantity and size of your metal pieces inside the graphite crucible More metal larger pieces and more metal in the crucible means more heating time Pic 1 Pic 2 WOODEN HANDLE WOODEN HANDLE LID CORRECT POSITION OF LID BACK VIEW Ls KILN s F HANDLE KILN s BODY TEMPERATURE CONTROLLER kd POWER SWITCH POWER CABLE TECHNICAL SPECIFICATION R9D 100 1130C ADJUSTED TEMPERATURE RANGE 0C 1130 C 32 F 2066 F 115 220 240V ON REQUEST ACCURACY 1 750 WATT INSULATION MATERIALS MUFFLE amp CE

7. of metal to be melted into the crucible we recommend cutting your metal into small pieces 10 20 mm work best The smaller the pieces the less time it takes to heat up and longer life of the crucible Close the graphite crucible by shutting the metal lid with the edges around the three sides Pic 4 Please make sure that it is in a correct position and cover the graphite crucible in full Pic 1 no edge lid s side going back to the kiln s handle Now you can connect your kiln to a power source and start your work SAFETY AND USEFUL TIPS FOR BEGINNERS Always make sure that the lid is closed properly in order to speed up the heating process and to reach the required temperature inside the chamber Always work with heat resistant gloves because this kiln is very compact and gets hot whilst working on high temperatures Do not open the lid two often Each time you open the lid the temperature inside the chamber drops and it will require more time to re heat Always place this kiln on a heat resistant work top A masonry or concrete floor is recommended but other protective material like metal or ceramic tiles can be used as well lf you do not use a graphite protector paint never heat the crucible continuously longer than 120 minutes Due to the structure of a graphite it may cause cracks to the crucible and a sudden leek of the molten metal inside the furnace A standard gold melting process lasts only about 60 minutes if melting
