observe these precautions may result in damage to the product or burns
or other injury due to malfunction or the discharge of fluids.

Problem
Cause
Remedy
Steam or
condensate
blows from the
exhaust outlet
or the overflow
outlet for
exhaust pipe
Little or no flow of cold water for
heat recovery
Correct water flow
Steam flow exceeds rated
capacities
Control the flow or add another
heat exchanger
Accumulation of scale, etc. on
the heat transfer coils
Clean
The heat-
recovery water
does not
become hot
Not enough steam flow
Secure the proper steam flow
Quantity of cold water for heat-
recovery is too great
Reduce flow
Accumulation of scale, etc. on
the heat transfer coils
Clean
There is back-
pressure on the
steam-using
equipment, or
steam cannot
be discharged
smoothly
There is a clog in the waste
steam inlet piping
Remove the clog
Check piping arrangement
Little or no flow of water for heat
recovery
Correct water flow
Accumulation of scale, etc. on
the heat transfer coils
Clean
Incorrect piping at exhaust outlet Correct the piping; see
