When HHO system is in action the engine must be started and the output hose from the tank must be connected to the suck pipe of the engine. Therefore when we install an HHO system it is necessary to make sure it is connected in the way the production starts after starting the engine, not in the first position of the key in the ignition system. In case electric installation of a particular car does not enable this we strongly recommend to use an automatic power switch a wide range of these can be found in our offer in the HHO Accessories section. This switch starts the HHO system after rise of voltage in the accumulator above 13V, i.e. after starting the engine or after specified time interval following starting, it depends on the type of a chosen switch. The HHO system is also switched off automatically after stalling of the engine. This is not important not only because of safety if a driver forgets to switch of the system in the car cabin after stalling the engine (HHO gas will not be produced when the engine is off), but also because of unwanted discharge of the battery which is not recharged by an accumulator on a stalled engine.

It is also possible to find other supplementary, so called secondary safety devices in our offer, e.g. a few kinds of bubblers divided according to their volume into categories for different car types, or one way valve suitable for an electrolyte or HHO gas circulation system.

HHO gas is extremely explosive and that is why using open fire during running a generator as well as disconnected output hose are strongly prohibited!
