Important - Jun-Air OF301-4B Modo De Empleo

Contents of box (motor only)
Your new compressor/vacuum pump should be delivered in
a clean and undamaged box. If not, contact your distributor
immediately. The box should contain the following:
• 1 OF00 motor
• Kit
• 1 capacitor
• 1 operating manual
GB
Installation (motor only)
Your JUN-AIR motor is very easy to operate. Observe the
following simple instructions and you will get many years'
service from your motor.
• Visually inspect unit for shipping damage, contact your
supplier immediately if you think the unit may have been
damaged.
Warning!
To avoid the risk of electric shock, do not install the
compressor in areas where it may get in contact with
water or other liquids. In which case protection is
required.
• Remove the plastic protection from the outlets. Mount the
enclosed O-rings on the plugs supplied with the motor in the
outlets that are not used (fig. 1a). Mount the nipple in the
outlet port, secure with loctite 275 and connect the pressure
pipe (fig. 1b + fig. 1c). Use only pressure pipes tolerating
a constant temperature of min. 150
pressure pipes have a sufficient internal diameter to avoid
pressure loss in the system. Check for leaks.
• Mount the supplied feet on the compressor (fig. 2). It is
possible to change the distance between the feet depending
on the actual mounting of the compressor (see drawings
with various feet measurements). It is important that the
compressor is mounted vertically to avoid damage to the
rubber feet. If the compressor is to be mounted in another
position, please contact JUN-AIR International A/S for
further information. The mounting of the rubber feet in the
90 mm track will reduce vibrations.
• Sufficient cooling from the surroundings is important. Place
the motor in a dustfree, dry and cool, yet frostfree, room. Do
not install in a closed cupboard, unless adequate openings
for ventilation are available on top and bottom (minimum
500 cm²/77.5 in² each). If the motor is placed under a table,
a minimum of 10 cm/ inch free height must be available
above the motor (fig. ), or an opening of Ø0cm/11.8
inches, corresponding to the top of the motor, may be cut in
the table. Ensure that the motor stands firmly on the floor.
• The intake air may be supplied from another place (for
instance outside).
Nipple and hose should then be mounted in the thread on
the top of the intake filter, and led to the external air source.
Ensure that hoses for the intake are sufficient to avoid
performance loss.

Electrical installation (motor only)
Warning!
Incorrect electrical connection may result in electric
shock. The electrical connection must be carried out
in accordance with local electrical regulations and by
qualified electrical engineers.
Note!
Earthing of all AC models must be ensured during
installation. The capacitor must be earthed, as failure to do
so may cause electric shock when touched. Plug the motor
into an earthed socket of nominal voltage and ensure that
fusing is adequate, see Technical Specifications page 35.
AC models
• For electrical connection, refer to page 44.
• Check motor plate for frequency, voltage and capacitor and
ensure that it corresponds to the voltage and frequency
used for the motor. The voltage stated on the motor plate:
120/240V (/) means that the motor can operate at 120V or
240V, but this requires recoupling of the internal wiring from
the electrical motor (see the electrical diagrams). 220-20V
(-) means that the motor may operate within the range of
220V to 20V without recoupling of the internal wiring.
• Mount bracket underneath the motor (fig. 4a).
• Mount capacitor vertically on mounting bracket (fig. 4b).
DC models
• For electrical connection, refer to page 45.
• During installation of the DC motor, check the motor plate
for the direction of rotation as it is important that the "+" and
"-" poles are connected in a correct way (fig. 5). Otherwise,
the fan may rotate in the wrong direction and the motor will
not be cooled. Consequently, the fan will not cool the motor
efficiently, causing a shorter lifetime of the compressor, and
invalidating warranty.
• A DC motor may be coupled directly on to the "+" and "-" poles
without thermal protection. In case of high temperatures and
leaks, we recommend the use of an external relay. This relay
will switch off the motor if the motor is thermally overloaded
(see electrical diagram for DC motors).
Operation (motor only)
• If the temperature of the motor is extremely low (for instance
after transportation or stocking), allow motor to get to room
temperature before switching on the motor.
• Do not use motor for compression of liquids and dangerous
gasses, such as petrol vapour and solvents.

Important!

The compressor/vacuum pump is only suitable for
atmospheric air.
• Do not remove protection covers during operation as it may
cause electric shock or risk of other personal injury (fig. 6).
• Ensure that motor is correct for air supply/vacuum flow
required, see Technical Specifications, page 7. • If supplied with a receiver, open the outlet cock on the
receiver and connect equipment.
