6 Operation
6.1 Oil level in the float housing
The oil level depends on the operating conditions of the facility and amounts
to approximately 20-50 mm in suction mode. If the oil level is higher, the float
housing may be completely filled with oil if the suction line is tight. This is
caused by the absorption of the air through the fuel oil. Over time, this results
in a reduction of the air cushion. When the operating conditions change (for
example, decreasing oil level in the tank), the air cushion is formed again in
the float housing.
6.2 Pressure mode
Elevated tanks may experience elevated pressures. This application case
does not interfere with the operation of the product.
In pressure mode with an oil pump, the use of a single line filter with return
supply is recommended.
 In the case of such applications, take appropriate measures to keep the
maximum permissible inlet pressure of 0.7 bar from being exceeded even
in the case of error conditions (defective pressure reducer), for example,
by means of a bypass valve, a pressure switch, etc.
 A drip pan must be placed below the burner hoses and the oil de-aerator
via which leaking oil is detected and the burner is switched off.
If the system requires a fuel oil de-aerator, use a "Flow-Control 3/K HT" with
upstream filter and brass filter cup or replaceable filter cartridge.
