1.1 Intended use
BWT heat exchangers are suited for the cooling of oils in hy-
draulic and lubrication systems with water. Their scope is
given by their specifications. The use in other applications is
not permitted without confirmation by Bühler Technologies
GmbH.
1.2 Scope of delivery
• 1 x Heat exchanger
• Product documentation
2 Safety instructions
The equipment must be installed by a professional familiar
with the safety requirements and risks.
Be sure to observe the safety regulations and generally applic-
able rules of technology relevant for the installation site. Pre-
vent malfunctions and avoid personal injuries and property
damage.
The operator of the system must ensure:
• Safety notices and operating instructions are available
and observed,
• The respective national accident prevention regulations
are observed,
• The permissible data and operational conditions are
maintained,
• Safety guards are used and mandatory maintenance is
performed,
• Legal regulations are observed during disposal,
• compliance with national installation regulations.
CAUTION
Hot surface
Burning hazard
Let the device cool down before maintaining.
CAUTION
High pressure
Hazard of injury due to flung off parts or oil, environmental
hazard due to oil.
a) Before starting any maintenance or repair to the oil cir-
cuit, make sure that the device is depressurized. This ap-
plies to the locking screws as well.
b) Avoid environmental pollution (oil spills) during cleaning
or maintenance of the oil circuit.
c) Use drip pans.
WARNING
Voltage flashovers
Electrocution hazard
Do not earth the heat exchanger when carrying out welding
work!
3 Transport and storage
The products should be transported only in its original pack-
aging or a suitable replacement. Secure device for transporta-
tion.
When not in use, protect the equipment against moisture and
heat. Keep it in a covered, dry and dust-free room at ambient
temperature.
4 Installation and connection
4.1 Installation site requirements
Plate heat exchangers should be mounted leaving adequate
clearance around each equipment for performing service
work, etc.
Install in any position. Only when used as an evaporator or ca-
pacitor require it to be installed vertically, any other installa-
tion position could result in decreased output.
4.2 Installing the heat exchanger
NOTICE
Piping must always be installed in such a way that no move-
ment in the piping and no unadmissible forces are trans-
ferred to the plate heat exchanger!
CAUTION
Damages at the connection
Ensure no vibration is generated in the lines to prevent the
plate heat exchanger connections from being damaged.
Incorrect installation or operation could result in a defect of
the welded joint at the connection, hence media mixing.
WARNING
Voltage flashovers
Electrocution hazard
Do not earth the heat exchanger when carrying out welding
work!
