Operation
7.1
Oil level in the float housing
The oil level depends on the operating conditions of the facility and
amounts to approx. 20-50 mm in suction mode. If the oil level is
higher, the float housing may be completely filled with oil if the suc-
tion 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 (e.g. decreasing oil level in
the tank), the air cushion is formed again in the float housing.
7.2
Pressure mode
Since in pressure mode with an oil pump there is no gas formation
caused by suction, it is not meaningful to use FloCo-Top-2 KM in this
mode. In pressure mode, it is recommended to use a single-line filter
with return pipe connection. If the system requires a oil de-aerator,
you can use a FloCo-TOP-2MM with retrofitted brass filter cup or re-
placeable filter cartridge, see chapter 10, page 20.
In the case of such applications, take appropriate measures to
prevent the maximum permissible inlet pressure of 0.7 bar from
being exceeded even in the case of error conditions (defective
pressure reducer, etc.), e.g. by means of a bypass valve, a
pressure switch, etc.
A drip pan has to be placed below the burner hoses and the oil
de-aerator.
7.3
Use in flood hazard areas
FloCo-Top-2 is suitable for flood hazard areas. FloCo-Top-2 is water-
tight up to 10 m water column (1 bar pressure).
After a flood, FloCo-Top-2 must be replaced.
Check FloCo-Top-2 for proper function.
