Introduction
Safety alert notices
This user guide is a guide for installation,
commissioning and maintenance of plate type
heat exchangers supplied by Danfoss.
It is meant for those who are responsible for the
installation, the use and maintenance of the heat
exchangers. We recommend that you read this
user guide carefully before commencing any
work.
This user guide is applicable for all plate type
heat exchangers produced and supplied by
Danfoss.
Danfoss can not be held responsible or liable for
damage as a result of incorrect installation, use
and/or maintenance of Danfoss plate type heat
exchanger or damage caused by as not
complying with the instructions in this user guide.
Please note that our plate type heat exchangers
are specially designed and built for the maximum
design conditions (pressures, temperatures,
capacities and type of fluids) provided by the
customer and stated on the nameplate.
The following must always be observed when
installing or servicing plate heat exchangers:
• Comply with national/local safety regulations
• Ensure that the heat exchanger is
unpressurized
• Ensure that the heat exchanger is cooled down
to a temperature below 40 °C (104 °F)
Warning symbols refer to safety alert notices.
Warning/safety notices should be observed
carefully to prevent:
Personal injury caused by:
• Wrong transport/lifting
• Burning/freezing as a result of touching
parts with extreme temperatures.
• Burning/freezing/poisoning as a result
of uncontrolled release of pressurized
media
• Contact with chemicals
• Touching sharp edges of e.g plates or
cassettes
Equipment damage caused by:
• Wrong transport/lifting
• Liquid hammering
• External forces
• Corrosion
• Chemical action
• Erosion
• Material fatigue
• Thermal and/or mechanical shock
• Freezing
• Blocking of the heat exchanger due to
particles
Sudden pressure peaks beyond the maximum
operating pressure (or pressure surges) which
can occur during start-up or stopping of the
system can severely damage the heat exchanger
and should be prevented. Danfoss can not be
held responsible for any damage as a result of
any operation deviating from the original design
conditions.
