START-UP
After the product has been ASSEMBLED and LEAK TESTING has been carried out
successfully, it is immediately ready for operation.
A pressure regulator must be connected to the outlet side of the changeover valve to reduce
the nominal connection pressure of the consuming device.
We recommend:
Low pressure regulator

Type FL 92-4

For larger flow rates to 12 kg/h we recommend this regulator:
Type BHK 052 (e.g. Part no. 05 298 00 or 05 299 00)
If LPG is withdrawn too quickly or is continuously withdrawn from the cylinder on the
operating side, the temperature of the gas falls and, as a result, the cylinder pressure drops
below the required inlet pressure of the regulator. LPG is then also withdrawn from the spare
cylinder.
Proper operation of the system is no longer guaranteed.
The LPG cylinders on both sides may be emptied simultaneously or also at different
rates.
OPERATION
The product can be damaged if the gas cylinder is moved!
Entrained liquid phase can cause the pressure to increase in the LPG system and damage
the product or the LPG system.
Do not move the gas cylinder while the system is in operation.
Cylinder replacement on the operating side
1. Close the cylinder valve
2. Loosen the connections
3. Replace the empty cylinder with a full one and connect the full one
The integrated gas backflow prevention device stops unwanted gas flows.
4. Open the cylinder valve
5. Check for leaks
6. The full cylinder is available as a spare
