1.1 Intended use

BNK off-line coolers are suited for transportation and air cool-
ing of oils in hydraulic and lubrication systems. 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 Off-line cooler
• 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.
• Nearby equipment is EMC protected, e.g. through shield-
ing.
• The current and voltage supply for the aggregate has a
(mains) separator with adequate switching capacity. Na-
tional requirements must be observed.

DANGER
Electric voltage
Risk of electric shock
a) Disconnect the unit from the mains when performing
any maintenance.
b) Secure the equipment from accidental restarting.
c) The unit may only be maintained and opened by instruc-
ted, competent personnel.
DANGER

Potentially explosive atmosphere

Explosion hazard if used in hazardous areas.
The device is not suitable for operation in hazardous areas
with potentially explosive atmospheres.
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.
3 Transport and storage
The product should only be transported inside the original
packaging or a suitable alternative. Ensure secure fastening
and mooring.
Units with air coolers have M10 eye bolts at the top of cooler
housing for transport. Please note, due to the variety of ver-
sions the mounting bracket is not located at the exact centre
of gravity and the cooler may swing when hoisted. Never hoist
by the M8 threads in the cooling elements!
Only use the engine transport eyes to hoist the engine
without add-ons.
Do not use the eye bolts according to DIN 580 in ambient tem-
peratures below -20 °C. The eye bolts could fracture in these
temperatures, injuring personnel and/or damage the system.
Do not strain the eye bolts more than 45° in the thread direc-
tion.
When not in use, the equipment must be protected from
moisture and heat. They must be stored in a covered, dry,
dust-free room at room temperature.
