Problem
Cause
Remedy
Fluid escapes (equipment is
leaking).
The equipment has been
damaged by waterhammer.
Replace the equipment with a new one.
Take appropriate measures to protect
the equipment against waterhammer.
Use e. g. non-return valves or a pump
steam trap.
The discharge capacity is too
low.
Insufficient thermal output of
the user.
The differential pressure is too
small.
Increase the steam pressure.
Lower the pressure in the condensate
line.
Use equipment with a larger discharge
capacity.
If necessary, use a pump steam trap or a
condensate return unit.
The discharge capacity is too
low.
Insufficient thermal output of
the user.
Insufficient deaeration.
Connect an additional air vent.
The flow rate is too low.
Loads have insufficient heat
capacity.
The response time is too
slow.
The equipment is too close to the
drainage point.
Install the equipment on an incline about
1–2 m away from the drainage point.
Do not insulate the equipment or the
pipe to the equipment.
The discharge capacity is too
low.
Insufficient thermal output of
the user.
The pipes do not have a
continuous fall in flow direction.
Make sure that the lines run with a
continuous fall in flow direction.
Fluid escapes (equipment is
leaking).
The equipment has been
damaged by frost.
Replace the equipment with a new one.
When shutting down the installation
make sure that all lines and the
equipment are completely drained.
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 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.
