3.1 Before initial use, soak the Fibreglass Element/Wick in mineral (baby) oil. Failure to carry this out will lead
 tothebreglasselementburningoutimmediately.The breglass element is considered to be a
consumable item and is not covered by warranty.
3.2 TaketopoffOilFiller(seeg.1)andllwithmineralbasedbabyoil(maximum:75ml).Thesightglasson
the right-hand side of the unit shows the oil level.
3.3 Connecttoworkshopairsupplyusingthequickconnectorontheleft-handsideoftheunit(seeg.1).
The inlet air pressure needs to be regulated to no more than 14psi (1bar).
3.4 Connect to 12V battery; green indicator light will show.
3.5 Press Heater Button on front of unit; red light will show indicating that the heater element is active. The
heater element is timed to operate for 4¾ minutes, after which time it will switch off automatically.
3.6 DO NOT removetheoilllercapwhilsttheunitisoperatingorisconnectedtoanairsupplyasthiswill
 causeoil(whichcouldbehot)tobeforcedfromthellerneck.
3.7 From cold, the heater may need to be activated more than once to achieve the required temperature
necessary for vaporisation.
3.8 Oncesmokeisstartingtoissuefromthehoseitmaybenecessarytotemporarilyincreasetheairow
 usingairowcontrol(seeg.1).Thiswillclearanyexcessoil.
3.9 Therequiredvolumeofsmokecanbeachievedbyadjustingtheairowrate,usingtheairowcontrol
and gauge for reference.
3.10 The smoke produced can be used in many ways to indicate the presence of leaks in either pressure or
vacuum systems. When smoke is introduced into the locality of the suspected leak, it will be carried by
 theowofaireithertoorfromtheaperture,dependingonthesystem.Observingthebehaviourofthe
smoke will pinpoint the problem.
3.11 Alternatively, smoke can be introduced into ducting by unfastening one end of the duct and plugging with a
suitable rubber cone from those included in the kit (see Fig.2) . The hose from the machine can then be
 coupledtothebushintheconeandtheductlledwithsmoke.Anyleakwillbedisplayedbya
jet of smoke coming from it.
3.12 The amount of smoke needed will vary with the capacity of the system being investigated.
3.13 If the smoke starts to dwindle, the heater element will need to be switched on for a further time.
