Control devices
In any case the plant must be equipped with a control device
for a safe stoppage of the machinery!
Plants which are approved to operate in hazardous areas
must be grounded using the corresponding earthing boss.
Connection of the motor according to data of the motor
manufacturer (see technical documentation or terminal box).
Observe the direction of rotation of the motor!
As standard FUNKE oil-air cooling units are designed for
suction operation.
In case of horizontal installation the used air must be drawn
off upwards. In any case the technical documentation must
be observed.
In case of high heat dissipation which would result in an
excessive heating of the air in closed rooms, outdoor
installation is advisable (observe type of protection of the
motor!)
Outdoors the oil-air cooling unit must be protected (e.g. by
roofing) against weather damage caused by rain, snow or
windborne sand etc. If outdoor installation is not possible, an
air duct should be provided to lead the used air to the
outside. Note:
Supplementary equipment like air ducts for instance can
cause loss of the heat dissipation or affect function of the
plant if not properly fitted!
If the oil-air cooling unit is operating with surface
temperatures exceeding 60°C protection against accidental
contacts should be placed or the area should be blocked
near passage ways!
In case of danger of heavy temperature jumps in the system
into which the oil-air cooling unit shall be installed (caused
for instance by control valves or shut-off valves or oscillating
pumps), appropriate measures must be taken to protect the
air-oil cooling unit!

6.2 Start up
6.3 Operating advice
An operation with heavy temperature jumps as well as
pressure surge can cause mechanical or material damage
and is generally not allowed!
Continuous or intermittent operation of the FUNKE oil-air
cooling unit is possible!
When operating the oil-air cooling units with direct-current
motors it must be taken into consideration that service life is
much shorter compared with three-phase motors.
Frequent startings or continuous operation reduce the life
time.
In case of fan drive by means of hydraulic motor, it is not
allowed to exceed the max. allowable rotational speed of the
fan!
(See technical data sheet or apply to our qualified
personnel.)
Essential operating data like pressure and temperature as
well as tightness of the system must be checked regularly,
(once monthly at least) depending on conditions of use.
Comply with safety instructions acc. to item 2.0!
1.
Check proper installation of all connections.
2.
Check filling of the oil-air cooling unit.
During, after filling respectively the oil-air cooling unit must be
completely vented. Any air in the system reduces the capacity
and may cause steam bubbles for instance.
3.
Start the motor. Check correct direction of rotation.
Check that the fan is free from deposits.
6.4 Shutting down / dismantling
Dismantling of the oil-air cooling unit and removal of the
cooler and motor connections is allowed only by qualified
personnel.
Follow safety instructions section 2.0!
Works on the oil-air cooling unit are allowed only if
- the fan drive has been disconnected from the electrical
supply, after the hydraulic drive has been disconnected from
the oil pump respectively.
- the unit is not under pressure, the temperature of the
medium to be cooled does not exceed 40°C and the unit
has been drained!
Working steps:
- Switch off main power supply
- Disconnect the motor
- Drain fluid from the system, carefully disconnect the fluid
lines, collect the fluid for reprocessing or regular disposal
(see data sheet for the fluid)
- Unscrew mounting bolts
- Apply protective covers on connecting openings
- Protect oil-air cooling unit against damage
- Possibly choose appropriate transport container
Take notice of the safety instructions section 2.0
