DESCRIPTION

Details and Instructions:

Operation: This sublimator or vaporiser as they are more commonly known, is most easily used from the back of the hive, where a small (¼”) hole is drilled in the back center of the floor beneath the bottom brood box, remember to inert the open mesh floor insert. This hole is the delivery vent for the sublimator stem. The OA vapour will rise up through the frames throughout the hive. Using a hole in the back of the hive eliminates any flying bees as the front entrance needs to be closed, we use a small piece of foam. The friction between the stem and drilled hole also holds the sublimator in place during vaporisation and this allows time to prepare the next dose. The bees will readily propolize this small hole. If you wish to close the hole after treatment, a plastic golf tee works great and is easily removed for next time.nnYou can use the ProVap220 in the front entrance as well if you wish. Simply plug the entrance with your chosen plug, cloth, foam etc. and insert the delivery tube at the side of the plugged entrance.nnConnect the vaporizer to your 220 volt power source. It will take approximately 2 minutes to reach operating temperature. The red sequence readout will display 230 when ready.nnIn the white Teflon lids (recess side up) place the appropriate amount of OA. Do NOT pack the OA in the lid; rather place it loosely. Use one gram per brood chamber regardless of the size. Use a 1/8 gram on a nuc. One gram is almost ¼ teaspoon, so on a two brood chamber hive; you would use ½ a teaspoon. Invert the vaporizer. Take the white Teflon lid containing the OA and push it onto the bowl (be careful the vaporizer bowl is very HOT!) Place the still inverted vaporizer stem (with lid attached) into the drilled hole then turn the vaporizer right side up and tap the lid. The acid will fall into the bowl and start to vaporize.nnThis will cause the temperature to drop to approximately 210-215 then very quickly start to rise. When it again reaches 230, it is finished vaporizing and you can move on to the next hive. This will take approximately 20 seconds! You need to seal any openings during and 10 minutes after vaporization. It is not unusual to see the temperature rise above 230 to 250 during treatments. This is normal and well within tolerances.nnThe temperature is preset for 230 C. This is the correct setting for the bowl of this vaporiser. However, you can change it as follows:n

  • n
  • Plug in the vaporiser. The upper red numbers will show the bowl temperature. The lower green numbers shows what the bowl temperature is set to achieve.
  • n
  • To change, depress the left side of the set button, and then depress the upper and lower arrows to the desired temperature.
  • n
  • Depress the set button again. This will save the new temperature setting.

nSafety!nnYou must use a respirator that is rated for organic acids!nnDetails:nnThe vaporizer is a 220 volt electrical appliance, 250 watts, 2.5 amps.nnMaintenance:nnAfter you have completed your treatments, you must clean the bowel with warm water. Make sure that water flows out through the stem. You can do this while the vaporizer is still warm (not hot) from usage. This is to prevent build up in the bowl and stem of OA that may block the stem. Make sure also you clean the cups of any residual OA. You may wish to carry a “pipe” cleaner in case the stem gets blocked during usage.nnAdditional Parts:nnShould you wish to purchase additional caps for the ProVap 220, they are readily available as additional accessories.
