PERFORMANCE CHECK
Provided the construction and the pipeline dimensioning are correct, the air cushion formed in the upper cover
during start-up will disappear fast. If, after longer period of operation, air is released in the deaerator cover
, or
if the burner goes to lock out state, there is a leak in the oil line. More air is aspired than can be handled by
addition of air to the fuel oil. The leak must be repaired to avoid any risk of fuel oil leakage while the installation is
at standstill.
A clearly audible noise from the burner pump can be a sign of a clogged-up filter element
. See
MAINTENANCE for replacing the filter element.
Filter cover
not filled to the top
Air and lightly volatile oil components may outgas from the operating medium and collect before the moistened
filter element. This applies in particular to single-pipe filters and low flow volumes. However, the invisible interior
of the filter element is completely filled with the operating medium, so that safe operation is not affected if the
filter cover is not filled to the top.
Should the filter cover level drop or should the cover fall dry, there is a leak in the system.
MAINTENANCE
The following checks are recommended in the course of annual maintenance or after prolonged standstill:
•
Check the deaerator and the connections for leaks
•
Visually check the plastic filter cover
and the deaerator cover
for damage: tears or deformation
•
Replace the filter element
A damaged or destroyed plastic filter cover
must be replaced for a new one. Steps to take when changing the
filter element:
The deaerator cover
can only be replaced as a complete assembly, i.e. together with deaerator screw
①
.
If the system has been submerged, any outside soiling of the filter should be cleaned off with a commercially
available household cleaning agent.
Do not use cleaning agents containing solvents as they might damage the plastic filter cover or other plastic
parts, e.g. the handle. For spares, see
List of spare parts
Replacing the filter element
Switch the burner off and stop the oil column from returning into the oil storage container - close the stop valves.
Use the collecting device!

clockwise.
Hold the new easy-change filter in position

OVERHAUL / REPAIR
If the measures explained under the headings START-UP, OPERATION and MAINTENANCE fail to achieve
regular re-START, and provided the construction and dimensions are correct, the GS Pro-Fi 3 must be removed
and sent to the manufacturer’s for a check-up. Any unauthorized handling will result in loss of the qualification
approval and any warranty claims.
