5.1 Units with membrane-drying unit
The unit draws in atmospheric air and
compresses it. It then transports the oil-free
compressed air to the membrane-drying
unit. The cooler and the membrane dryer
extract any moisture from the compressed
air. The oil-free, hygienic and dry air is made
available to the consumers in the pressure
receiver.
If compressed air is removed for a
consumer, the receiver pressure drops.
When the switch-on pressure has been
reached, the unit is automatically switched
on again via the pressure switch. When the
cut-off pressure has been reached, the unit
is automatically switched off. A safety valve
prevents the maximum permissible receiver
pressure from being exceeded.

6 Prerequisites
6.1 Area of installation
The installation area must fulfill the
following requirements:
– Closed, dry, well ventilated room.
– Not a purpose-built room (e. g. heating
or wet room).
– Install the unit on a clean, level and
sufficiently stable surface (take the weight
of the unit into account).
– Install or fit the unit so that the type plate
is easily read and the unit is easily
accessible for operation and maintenance.
– Install the unit so that the socket outlet to
which the unit is connected is easily
accessible.
– Room temperature: 41 to 104°F (5 to 40°C).
– Ensure that a sufficient distance to the wall
is maintained, so that the air can flow in
and out without any obstruction.
Note: The air is filtered during the intake. The
composition of the air is not affected in the
process. The air taken in should be free of
harmful substances (e.g. do not draw in air
from a basement garage or from directly
next to a suction machine).
7 Operation
7.1 Remove the packaging
For safe transportation, the unit is securely
protected with packaging material.
– Remove the packaging material.
– Remove the protective film.
– Check the unit for damage in transit.
– Only lift the unit using the transport
handles and/or from the floor.
7.2 Fit the spacer
– Fit the spacer (22) to the back of the unit to
guarantee ventilation (leave the spacer in
place throughout the service life of the
unit).
NOTICE
Risk of overheating due to
insufficient ventilation
The unit produces heat. This can
lead to heat damage and/or to a
reduction in the service life of the
unit.
– Do not cover the unit.
– Air must be able to flow in and
out unobstructed.
– Ventilation openings must be
sufficiently large.
– For installed units, an independent
ventilation system may be
required in unfavorable cases.
6.2 Pressure receiver test
The operator must comply with the national
directives.
1065Y4_M_Lab Compressors_22222-29,-30.indd 9 12/22/2017 2:09:04 PM
7.3 Set up compressed air connection
The unit has two compressed-air connections. The compressed-air connection on the
operating panel takes the form of a
quick-release coupling. The compressed-air
connection on the back of the unit takes the
form of a plug-in connection. The
compressed-air connections can be used
individually or together.
Quick-release coupling - operating panel
The compressed-air connection to the pres-
sure reducer has a constant pressure (set at
the factory) of 0 to 0 to 87 psi (6 bar), adjustable on the rotary knob.
– Compressed air is extracted at the quick-
release coupling (0.28"/7.2 mm) via a hose
adapter piece on the unit's operating
panel.
– Secure the pressure hose to the hose
adapter piece using a hose clip.
9
Page 10
– Connect the hose adapter piece to the
quick-release coupling.
Plug-in connection - back of unit
The compressed-air connection on the back
of the unit has the unreduced receiver pressure. This varies between 87 and 116 psi (6
and 8 bar) (factory setting). This must be
taken into account when connecting to a
mains line. Any flow from the mains line into
the unit is prevented via an internal check
valve.
– Connect the flexible pressure hose with
plug-in connection (0.39"/10 mm) to the
compressed-air connection on the back of
the unit.
7.4 Condensate
The unit has a vaporization system.
However, at high ambient temperatures
(>86°F/30°C) and at high levels of humidity
(>75% RH), condensate may not be fully
vaporised. Any remaining condensate is
then drained off to the outside via a condensate overflow. In these applications, a
condensate collection tank must be placed
beneath the condensate overflow.
7.5 Electrical installation
– Connect the mains cable to the inlet
connector on the back of the unit.
– Connect the mains cable to a properly
installed socket with PE conductor.
– Lay the mains cable without any
mechanical tension.
– Before commissioning, compare the power
supply voltage to the voltage information
on the type plate.
DANGER
Electric shock due to damaged
mains cable or connector
Electric shocks can cause serious
personal injury
– If the mains cable or connector is
damaged, do not start up the unit.
– Replace the damaged mains
cable.
7.6 Motor protection
The motors in the units are equipped with a
motor protection switch that switches off the
pressure switch in the event of overcurrent.
Overcurrent may be caused by faults (e.g.
blockages). In cases such as these, the cause
of the fault must first be determined and
then eliminated.
Note: The unit can be switched back on
using the rotary knob on the pressure
switch.
– Allow the unit to cool down.
– Switch off the unit.
– Disconnect the mains plug and prevent the
unit from being switched back on again.
– Open the unit lock.
– Remove the unit cover.
– Switch the rotary knob on the pressure
switch back on.
– Refit the unit cover.
7.7 Overtemperature protection
The motors in the units are equipped with a
temperature switch that switches the unit off
if it overheats. In cases such as these, the
cause of the fault must first be determined
and then eliminated.
Note: If the unit is switched off via the
temperature switch, the unit's fan continues
to run.
NOTICE
Automatic unit startup after
cooling down
– Allow the unit to cool down.
