The sightglass or water level
gauge does not offer an
unambiguous evaluation of
the operating condition.
The sightglass or water level
gauge is dirty, worn or scratched.
Replace the sightglass or water level
gauge.
The equipment is blowing off
live steam.
The external bypass is open.
Completely close the external bypass.
The equipment is blowing off
live steam.
The control unit is damaged or
worn.
Replace the control unit.
The equipment is blowing off
live steam.
Dirt deposits, precipitated solids
or foreign particles have
accumulated in the equipment.
If fitted, operate the float-lifting lever.
Clean the pipes.
Clean all internals.
If necessary, replace internals or the
whole equipment.
The equipment is cold or only
warm to the touch.
The sealing plugs are still
attached to the connections.
Remove the equipment.
Remove the sealing plugs.
Mount the equipment.
The discharge capacity is too
low.
The equipment is cold or only
warm to the touch.
The shut-off valves for fluid flow
are closed.
Fully open the shut-off valves.
The discharge capacity is too
low.
The equipment is cold or only
warm to the touch.
Insufficient thermal output of
the user.
The inlet, outlet or the equipment
is dirty.
If fitted, operate the float-lifting lever.
Clean the pipes.
Clean all internals.
If necessary, replace internals or the
whole equipment.
The discharge capacity is too
low.
Insufficient thermal output of
the user.
The equipment is undersized.
Use equipment with a larger discharge
capacity.
The discharge capacity is too
low.
Insufficient thermal output of
the user.
Steam pressure and condensate
flowrate fluctuate considerably.
The pressure upstream of the
equipment is too low for the used
equipment type.
Use equipment with a larger discharge
capacity.
If necessary, use a pump steam trap or a
condensate return unit.
