PREPARATION FOR USE
PRE-START CHECKLIST
1. Ensure the On/Off switch (6) is in the OFF position.
2. Plug the power cord into the correct branch circuit
GB
receptacle. See Electrical Connection (above).
3. Ensure air tank is drained, see Draining Air Tank under
Maintenance.
4. Ensure the drain valve (2) is closed.
5. Ensure safety valve (9) is functioning properly, see Checking
Safety Valve under Maintenance.
6. Turn regulator knob (4) anticlockwise until fully closed.
Ensure regulated pressure gauge reads 0 bar (0 psi).
7. Attach hose and accessories.
m WARNING: Risk of unsafe operation. Firmly grasp hose
in hand when installing or disconnecting to prevent hose
whip.
8. Ensure all covers and labels are in place, legible (for labels)
and securely mounted. Do not use compressor until all items
have been verified.
m WARNING: Risk of bursting. Too much air pressure causes
a hazardous risk of bursting. Check the manufacturer's
maximum pressure rating for air tools and accessories. The
regulator outlet pressure must never exceed the maximum
pressure rating.
INITIAL SET-UP
m WARNING: Do not operate this unit until you read and
understand this instruction manual for safety, operation and
maintenance instructions.
BREAK-IN PROCEDURE
m WARNING: Risk of property damage. Serious damage may
result if the following break-in instructions are not closely
followed.
This procedure is required before the air compressor is put
into service for the first time and when the check valve or a
compressor pump/motor has been replaced.
1. Ensure the On/Off switch (6) is in the OFF position.
m CAUTION: If hose is not connected to Quick Connect body,
pull coupler back until it clicks to prevent air from escaping
through the quick connect.
2. Plug the power cord into the correct branch circuit
receptacle. See Voltage and Circuit Protection under
Installation.
3. Open the drain valve (anticlockwise) fully to permit air to
escape and prevent air pressure build up in the air tank
during the break-in period.
4. Move the On/Off switch to the ON position. The compressor
will start.
5. Run the compressor for 20 minutes.
8
6. After 20 minutes, close the drain valve by turning clockwise.
The tank will fill to cut-out pressure and the motor will stop.
7. Compressed air will be available until it is used or bled off.
STARTING
Check that the mains power matches that indicated on the
electrical data-plate - the permissible tolerance range is +/-5%.
Turn or press into position "0". Fit the plug in the power socket
and start the compressor, moving the On/Off switch into
position "I".
The compressor is fully automatic, and is controlled by the
pressure switch which stops it when tank pressure reaches
maximum value and restarts it when it falls to minimum value.
The pressure difference between maximum and minimum
values is usually about 2.4 bar (35 psi). E.g.: the compressor
stops when it reaches approximately 13.8 bar (200 psi) -
maximum operating pressure) and restarts automatically when
the pressure inside the tank drops to 11.4 bar (165 psi).
After connecting the compressor to the power line, run it to
maximum pressure and check exactly how the machine is
operating.
m WARNING: The head/cylinder/delivery tube unit can reach
high temperatures. Take care when working near these parts,
and do not touch them to avoid possible burns.
IMPORTANT
The electro-compressors must be connected to a power socket
protected by a suitable differential switch (thermal breaker).
The motor is equipped with a thermal overload protector
located inside the winding - this stops the compressor when
motor temperature reaches excessively high values. If the
thermal overload protector is tripped, place the switch in the
"Off" (0) position. Unplug the compressor until it has completely
cooled. When cool, reattach the plug to the power supply
and move the switch to the "On" (I) position. The compressor
should start normally. If not contact your nearest service centre
immediately.
ADJUSTING OPERATING PRESSURE
You do not have to use the maximum operating pressure at
all times. On the contrary, the pneumatic tool being used
often requires less pressure. On compressors supplied with
a pressure reducer, operating pressure must be correctly
adjusted.
Adjust pressure to the required value by turning the knob (4)
clockwise to increase pressure and anti-clockwise to reduce
it. When you have obtained optimum pressure, lock the knob
by pressing it downward. For pressure reducers equipped
without a pressure gauge, the set pressure can be seen on the
graduated scale located on the reducer body.
On pressure reducers equipped with a pressure gauge,
pressure can be seen on the gauge itself.
