Automatic Changeover Switch Gas Regulator Kit 30mBar for Motorhomes Includes Two Pigtails
Changeover switch with regulator for use with red vapour tanks, alu bottles and LPGSHOP composite refillable cylinders.
It is two stage regulator for better pressure stability, mandatory for mobile units. Second stage ensures that gas is evenly evaporated and no liquid gas is let into the system.
The connectors on inlet side are M20 1.5 parallel thread, also know as W20 - it is caravaning standard.
The outlet is 8mm copper pipe compression fitting.
Outlet pressure is 30mBar which is suitable for most appliances designed for motorhomes.
It comes with a bracket to secure regulator to bulkhead. Inlet should be positioned upwards and higher than outlet of the bottle
The automatic changeover ensures continuous gas flow, automatically changing the gas withdrawal from the empty “service” cylinder to the full “reserve” one. The full-empty indicator incorporated into the bonnet of the automatic changeover indicates the exhaustion status of the “service” cylinder. The indicator color changes from green to red, when the “service” cylinder is exhausted. The rotation of the automatic changeover handle to the full “reserve” cylinder restores the green color on the indicator.
Start up - Turn two cylinders’ gas valves on at the same time. This is fundamental, which ensures the automatic changeover the ability to continuously supply the gas appliance, in case the service cylinder becomes empty. The automatic changeover cannot turn to the reserve gas bottle if its valve is closed.
Reading the automatic changeover’s indicator: when the service gas bottle is full - When the two gas cylinders are full, the automatic changeover’s indicator turns to green while opening gas valves A and B. - The arrow on the automatic changeover’s knob indicates which one of the two gas cylinders is supplying gas: that is to say the “service gas bottle”. The other cylinder is the “reserve gas bottle”.
Reading the automatic changeover’s indicator: when the service gas bottle is empty - When the service bottle is getting exhausted and reaches pressure values of inversion (lower than 10 PSIG), the automatic changeover turns automatically to the “reserve gas bottle” and the gas appliance continues working. In this case the automatic changeover’s indicator turns to red: the end user gets to know that the “service gas bottle” is empty: it is not supplying gas any more.
