Your GAS IT bottle or tank is now fitted, can I just go and fill up now? NO, not until you have followed the following procedures!
Firstly before filling any bottle or tank you must make sure you have emptied any high pressure air from the tank or bottle.
Manual outlet
On manual tap equipped bottle or tank, please open the manual tap before you connect anything to it ( no pigtail or regulator ) and wait until the air is evacuated then shut the tap and follow the info below.
Electronic outlet
For the electronic equipped bottles and tanks, before wiring up any GAS IT electronic ECU please power the pre installed tank solenoid with 12 volts DC ( from a vehicle battery for example - please make sure the battery and solenoid polarity is correct before doing so ) once the air is out of either system, carry on with your install of the tank and ECU as per the sections on the fitting paperwork ( supplied and on the knowledgebase. )
Once you are sure you've followed the right sections and do the install correctly for the regulation you need to comply with you then do full functional tests on the tank and hoses regulator etc and habitational type pressure checks using air first, then vapour LPPG before actually putting any liquid LPG in from the Autogas filling station pump - otherwise if there's a leak or its not working properly you can simply remove the small amount of air or vapour LPG and not have to waste a full bottle or tank of gas.
We cannot be held responsible for your having to remove a full tank of LPG if there is a issue as full tests and functional workings should be carried out first.
Find attached a copy of the relevant purging section from the N.C.C. CoP 306 ( National Caravans Councils ) Code of Practice 306.
Inline with N.C.C commissioning requirements we only recommend the system be commissioned with air first before putting any LPG in the tank ( full air compressor pressure of no more than 160 psi can be used as the pressure in the tank when LPG is pumped in is around 150 psi).
1) When you fill with air first you can check the functionality of the system and then carry out your first leak checks from the fill point to the appliances. Once you have completed the air test and you have totally removed all the air you pumped in from the tank ( by releasing an end of the pigtail and opening the outlet on the tank ) you can then close the outlet and introduce LPG vapour ( not liquid ) to carry out further leak checks and then run the complete Gas system and appliances.
When your completely satisfied there are no leaks and functionality of the tank or bottle, only then initial put the minimum amount of Liquid LPG ( no more than 2 ltrs ) in the system until the system is fully tested for functionality and leaks once again. This is so should you find any problems you do not have to empty and waste a full tank of gas.
We always recommend that you check to make sure that any pressurised air that might have been left in the bottle or tank when assembling the tank and testing it for leaks, is fully removed from the bottle or tank before attempting to fill. This is done simply before you attempt to fill the tank or bottle by opening the outlet tap before a pigtail or regulator is connected to so that any compressed air pressure will simply fall away to nothing more than atmospheric pressure.
Once any pressurised air is removed then simply close the tap and refit any hoses or regulators that need to be fitted.
Now follow the N.C.C.'s Guidelines on introducing LPG for the first time to your GAS It tank or bottle.
