We recommend that you discuss the installation of an
industrial round pin plug and socket with your electrician.
 IMPORTANT! The use of extension leads to connect these
compressors to the mains is not recommended as the resulting
voltage drop reduces motor, and therefore pump performance.
1.1. ELECTRICAL SAFETY
WARNING! It is the responsibility of the owner and the operator to
read, understand and comply with the following: You must check all
electrical products, before use, to ensure that they are safe. You must
inspect power cables, plugs, sockets and any other connectors for wear
or damage. You must ensure that the risk of electric shock is minimised
by the installation of appropriate safety devices. A Residual Current
Circuit Breaker (RCCB) should be incorporated in the main distribution
board. We also recommend that a Residual Current Device (RCD) is
used. It is particularly important to use an RCD with portable products
that are plugged into a supply which is not protected by an RCCB. If in
any doubt consult a qualified electrician. You may obtain a Residual
Current Device by contacting your Sealey dealer. You must also read
and understand the following instructions concerning electrical safety.
1.1.1. The Electricity at Work Act 1989 requires that all portable
electrical appliances, if used on business premises, are tested
by a qualified electrician, using a Portable Appliance Tester
(PAT), at least once a year.
1.1.2. The Health & Safety at Work Act 1974 makes owners of
electrical appliances responsible for the safe condition of those
appliances and the safety of the appliance operators. If in any
doubt about electrical safety, contact a qualified electrician.
1.1.3. Ensure that the insulation on all cables and on the appliance is
safe before connecting it to the power supply. See 1.1.1. and
1.1.2. and use a Portable Appliance Tester.
1.1.4. Ensure that cables are always protected against short circuit
and overload.
1.1.5. Regularly inspect power supply cables and plugs for wear or
damage and check all connections to ensure that none is loose.
1.1.6. Important: Ensure that the voltage marked on the appliance
matches the power supply to be used and that the plug is fitted
with the correct fuse - see fuse rating below.
1.1.7. DO NOT pull or carry the appliance by the power cable.
1.1.8. DO NOT pull the plug from the socket by the cable.
1.1.9. DO NOT use worn or damaged cables, plugs or connectors.
Immediately have any faulty item repaired or replaced by a
qualified electrician.
1.1.10. Model Nos SAC3503B and SAC3103B are supplied with a
flying lead without a plug. Jack Sealey Limited recommend
a 16 amp protected supply. When connecting to a 16 amp
protected supply, contact a qualified electrician, to ensure
connection to a suitably rated supply.
*Provided a good 230V supply is available and the lead
length is not increased from that supplied, the compressor
may operate from a 13 amp supply. This very much
depends upon the quality of your power supply.
1.2 Wiring a BS 1363/A UK 3 Pin Plug
If in doubt contact a qualified electrician.
a) Connect the GREEN/YELLOW earth wire to the earth
terminal ‘E’.
b) Connect the BROWN live wire to the live terminal ‘L’.
c) Connect the BLUE neutral wire to the neutral terminal ‘N’.
d) After wiring, check that there are no bare wires, that
all wires have been correctly connected, that the cable outer
insulation extends beyond the cable restraint and that the
restraint is tight.
Double insulated products, which are always marked with this
symbol , are fitted with live (brown) and neutral (blue) wires
only. To rewire, connect the wires as indicated in diagram.
DO NOT connect either wire to the earth terminal.

3. PREPARATION
3.1. Remove compressor from packaging and inspect for any
shortages or damage. If anything is found to be missing or
damaged contact your supplier.
3.2. Save the packing material for future transportation of the
compressor. We recommend that you store the packing in a
safe location, at least for the period of the guarantee. Then, if
necessary, it will be easier to send the compressor to the
service centre.
3.3. Confirm that the mains voltage corresponds with the voltage
shown on the compressor data plate.
3.4. Assemble the wheels and swivel castor using the nuts, bolts
and washers supplied (fig.8).
3.5. The compressor should be operated on a horizontal flat
surface, or one that does not exceed 5° either transversely
(tyres fully inflated to 1.5bar) or longitudinally with chocks
(fig.3), and should be in a position that allows good air
circulation around the unit (see 1000mm nominal).
3.6. Before using the compressor check the oil level by referring
to the oil sight glass (fig.4C). On a horizontal surface, if the
oil level is not up to the red centre mark it should be further
topped up with recommended oil (See section 5.7). To top up
unscrew plug (fig.4B).
3.7. Screw the back half of a filter unit into the port openings in
each head as shown in (fig.4.A). Place a filter cover over
each threaded rod protruding from the back half of the filter
and secure each with a wing nut. Refer also to (fig.7).

4.3. STARTING THE COMPRESSOR.
4.3.1. Your compressor is fitted with a push/pull type on/off
switch. To turn the compressor "on" pull the switch knob
upwards. To turn the compressor "off" push the knob
downwards. (See fig.5.1)
4.3.2. Check that the on/off switch is in the “off” position and
the regulator tap (fig.5.2) is closed (Zero ‘0’ bar).
4.3.3. Plug mains lead into mains supply and start the compressor
by pulling the switch knob (fig.5.1) upwards.
4.3.4. Leave the compressor running with no air line or tools
connected, and regulator (fig.5.3) set to maximum pressure
(fully clockwise). Make sure that the pressure in the tank
rises and that the compressor stops automatically when the
maximum pressure value is reached. This value is written on
WARNING! Ensure that you have read, understood and
apply Section 1 safety instructions.
4.1. IMPORTANT. The use of extension leads to connect this
compressor to the mains is not recommended as the
resulting voltage drop reduces motor, and therefore
pump, performance and could damage your compressor.
4.2. Take care when selecting tools for use with the
compressor. Air tool manufacturers normally express the
volume of air required to operate a tool in cubic feet per
minute (cfm). This refers to free air delivered by the
compressor (‘air out’) which varies according to the
pressure setting. Do not confuse this with the
compressor displacement which is the air taken in by
the compressor (‘air in’). ‘Air out’ is always less than ‘air
in’ - due to losses within the compressor.
4. OPERATION
SAC3503B/SAC3103B Issue No: 1 - 01/06/13
©Jack Sealey Limited 2013
the specification plate and shown on the gauge (fig.5.4). This
may take in excess of 5 minutes. The compressor will now
operate automatically. The pressure switch (fig.5.1) stops the
motor when the maximum tank pressure is reached and
restarts it when pressure falls below the minimum threshold,
approximately 2bar (29psi) less than the maximum pressure.
4.3.5. Stop the compressor by pushing the switch knob (See fig.5.1)
downwards. The compressed air inside the compressor head
will flow out via the air line tube situated beneath the switch
housing. Restart is made easier and prevents the motor from
being damaged. DO NOT, other than in an emergency, stop
the compressor by switching off the mains power, or by
pulling the plug out, as the pressure relief will not then occur
and motor damage may result upon restart.
When the compressor runs correctly and is stopped correctly
there will be:
(a) A whistle of compressed air when the motor stops,
(b) A protracted whistle (about 20-25 seconds) when the
compressor starts with no pressure in the tank.
4.3.6. The output pressure is regulated by the pressure regulator
(fig.5.2). Turn the knob clockwise to increase pressure and
counterclockwise to reduce it. The knob can be locked at any
required setting by tightening the locking ring (fig.5.5) up
against the underside of the knob. To determine the correct
working pressure for any piece of equipment check the
corresponding manual. When the compressor is not being
used set the regulated pressure to zero so as to avoid
damaging the pressure reducer.
NOTE: a) If the motor does not cut in and out, but runs
continuously when using an air appliance, the capacity of the
compressor may be too small for the equipment or tool.
b)The gauge (fig.5.4) indicates the pressure inside the
main tank. The gauge (fig.5.3) indicates the
pressure supplied to the air equipment. Should the pressure
in the main tank exceed the pre-set switch (fig.5.1)
maximum, the safety valve (fig.5.6) will activate.
WARNING! For this reason DO NOT tamper with, or
adjust, the switch or safety valve.
4.3.7. The compressor is fitted with a reset trip, located in the
connection box on top of the motor. The reset button is on the
side of the box (fig.2). Should the trip activate, leave for 1
minute before pressing the button to reset. For possible
causes of trip activation and remedies see section 6
Troubleshooting.
