AT T E N T I O N !
If a hoist is operated with a service unit, this
should not be mounted further than 5 m
away from the hoist.
The ambient temperature must be a minimum of 0° C.
It must not exceed 50° C.
N OT E : If, at the request of the customer, a service unit
is installed in hoists in motorised trolleys and lifting
gear, it will be configured at the factory.
A maximum connecting pressure of 10 bar is permitted
for the service units supplied by JDN. Higher pressures
must be reduced to a permissible value, upstream of the
service unit.
The service unit consists either of two elements, filter
controller and oiler, or of the filter controller only.

* )
The filter controller is set to an actual pressure of 5.4
bar (3.6 bar) in the factory (actual pressure when lifting
the nominal load). In this setting, the manometer can
indicate a pressure of over 6 bar (4 bar) with the motor
switched off. For correct adjustment, a pressure of at
least 7 bar (5 bar) upstream of the service unit is
required.
왘
Lift the regulator knob.
왘
Turn the regulator knob until the manometer
indicates a pressure of 5.4 bar (3.6 bar). Clockwise:
higher pressure, Anti-clockwise: lower pressure
왘
Lock the regulator knob by pressing it down.
Alternatively, the filter controller can be set to a
pressure of 6 bar (4 bar) in the absence of an air
stream. This setting is only correct for a pressure of
at least 7 bar (5 bar) upstream of the service unit.
왘
Depressurise the air line downstream of the service
unit and close it again.
왘
Turn the regulator knob anti-clockwise, in order to
release the adjusting spring.
왘
Turn the regulator knob until the manometer
indicates a pressure of 6 bar (4 bar). Clockwise:
higher pressure Anti-clockwise: lower pressure
왘
Lock the regulator knob by pressing it down.
* )
Values for 4-bar hoists in brackets
If the nominal pressure of 5.4 bar (3.6 bar) cannot be
achieved despite a sufficiently high pressure upstream
of the service unit, then the air line cross-section is
too small.
