OPERATION OPERATION Unscrew the lid of the tank & fill with 1 litre ( US 1 Quart ) of VENTECH ripening fluid or an approved equivalent. The tank holds 1.5 Litres of fluid, but has a dead volume of 0.25 L when the tank is empty. The tank can be filled up to the necj initially, but otherwise 1 litre is sufficient for one ripening session. - Page 6 & domestic load is switched off. In some developing countries, these limits can also be exceeded. For this reason, the Ventech gas generator has a built-in protection circuit which will automatically switch off once this safe working limit has been exceeded without damage to the components.

We also recommend that if you are have problems ripening, that you check the gas levels with with a gas sampler such as the GASTEC details of which are at the end of the manual.
