It has an output or 150 W. The power source can either be an accumulator (car battery.12 volt, 12 ampere, capacity > 40 Ah) or a car cigarette lighter used with an extension lead.Please note safety precautions !Wear a protective mask !Minimum dimension of the entrance: 14 mm high and 90 mm broad Minimum distance between bottom board and frames: 2 cm Oxalic acid is filled in the pan, then the appliance is inserted through the entrance of the hive.optima vaporizer steam inhalerDue to the heating action of the pan, the oxalic acid liquefies and vaporises.cara pakai vaporizer x6Oxalic acid vapour fills the hive and all the bees and surfaces are then covered with a very thin layer of oxalic acid crystals.vaporizer peppermint oil

These fine crystals are tolerated well by the bees, but have a deadly effect on varroa mites.Time The treatment should not be made during heavy bee flight.Furthermore, the temperature should not be below + 2°C.The use of the VARROX-vaporiser is particularly suitable for the follow up treatment in brood-free colonies.*One spoon, filled loose and without pressing, corresponds to one gram Oxalic acid-dihydrate.Each VARROX-vaporiser is supplied with a measuring spoon.Placing the VARROX-vaporiser The appropriate amount of oxalic acid-dihydrate is placed into the VARROX-vaporiser.Take care that the oxalic acid is not spilled when holding the VARROX-vaporiser at an angle or by twisting it.Afterwards, the appliance is inserted through the entrance of the hive into the middle of the bottom of the hive, until the metallic support is fully inside.If bees are sagging over the pan, they must be strongly encouraged upwards with smoke.The treatment should only be used in hives normally occupied with bees.

It must not be used at close range of wax (minimum distance 2 cm).Minimum dimensions of the entrance: 14 mm high and 90 mm broad.If insertion through the entrance is not possible because of the construction of the hive, use the opening of the diagnosis drawer where possible.In that case, the entrance of the hive must be shut tightly.Hint:  Depending on the height of the entrance and the bottom of the hive, it is recommended to fit the VARROX-vaporiser in evenly by bending down both sides of the metallic support a few millimetres.The distance between the bottom of the hive and the heating element can be increased and the source of the heat is taken off the bottom.Attention:  Due to the heating action of the pan, there is a danger of melting plastified varroa bars and synthetic hives.The VARROX-vaporiser reaches temperatures of up to 300°C and can create patches of heat on the bottom and frames.Sealing up the hive Seal the whole entrance (or diagnosis drawer) around the handle of the VARROX-vaporiser using strips of foam or cloth.

Open floors should be shut tightly on the whole surface.Duration of the treatment After the hive is sealed up, the vaporiser should be switched on for 2 ½ minutes.As a rule, 2 ½ minutes are enough for the vaporisation of the oxalic acid.In the first colony that has to be treated, the heating time may be longer, because the vaporiser is still cold.An extra minute heating is required if using the extension lead.One of the battery-clips of the lead should be constantly connected with the source of power using the contact of the second clip to switch the appliance on and off.It makes no difference if the plus or minus-poles are connected accordingly or not-the function of the heating is not reduced.After switching off the VARROX-vaporiser, wait for about 2 minutes before the appliance is pulled out, so that the oxalic acid-vapour can settle down.Once removed, ensure that the entrance of the hive is shut tightly again and left shut for another 15 minutes.After taking out the VARROX-vaporiser, it should be cooled in a bucket of water, so that with the next use, no vaporisation begins before the appliance is inserted into the hive.

Hint:  With the use of several VARROX-vaporisers, bigger apiaries can be treated more time-effectively.Oxalic acid-dihydrate (Oxalic acid-crystals) Oxalic acid is an unhealthy, toxic and corrosive substance.When filling the VARROX-vaporiser and during the treatment, it is absolutely necessary to wear protective glasses, a protective mask (FFP 3 S/L), gloves and long-sleeved clothes.In the case of eye contact, immediately wash the acid out with water.If ingested immediately go to a doctor.Working safety during the treatment For the treatment, oxalic acid-dihydrate (C2H2O4 x 2 H20) CAS-No.205-634-3 has to be used.Normally available in pharmacies.Treatment in brood free colonies The VARROX-vaporiser can be used in brood-free colonies, normally seasons without honey flow.With the VARROX-vaporiser a very good efficacy of > 96% can be reached and thus it can decimate the varroa-mite-population reliably to a very low level.Thereby, optimal preconditions for the new season are created for the bees.

If there is a mite fall of more than 1000 varroa mites caused by the treatment, or if it is uncertain whether there was brood in the colonies, a second treatment is recommended.The optimal time for it, is two weeks after the first treatment.Two or more treatments are very well tolerated by the bees.Treatment of swarms / artificial swarms Swarms and artificial swarms can be treated at any time.Treatment of nucleus Treatment of queenright nuclei should be carried out before the brood is sealed, if possible.Attention:  Queenless colonies react very conspicuously to the treatment with an increased activity in the hive and by leaving the hive.After the treatment there is still some acid left in the pan Heating time is too short: Heat longer!Accumulator is weak and produces too low a capacity: Charge accumulator!Caution with synthetic hives and plastified varroa screens: With hives or varroa screens made of synthetic material, an isolation platter (minimum 4 mm thick) must be put under the appliance.
