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 1.1.10. below).

1.1.7. DO NOT pull or carry the appliance by the power cable.

4. OPERATION

4.1. Preparation

4.1.1. Remove compressor from the packaging.

4.1.2. Confirm that the mains voltage corresponds with the voltage
shown on the compressor data plate. Fit a suitable 3 pin
industrial plug - see section 1.1.10. of the Safety Instructions.

4.1.3. Take care to transport the compressor correctly, DO NOT
overturn it or lift it with hooks or ropes.

4.1.4.Positionthecompressoronaat,horizontalsurfaceand

ensure it is securely bolted down. Site in a well ventilated
area, protected against atmospheric pollution and not in a

4.1.6. Remove the plastic transit plug from the oil filler hole, if fitted,
(fig.4) and replace it with the dipstick. It is a push fit.

4.1.7. Before using the compressor, check the oil level in the
sight glass in fig.2. If the oil is not up to the max. mark, it should
be topped up with synthetic oil (see section 5.7. for
recommended oils). We DO NOT recommend using mineral oil
in these compressors. DO NOT overfill.

2. INTRODUCTION

Heavy duty three phase compressors suitable for the professional
workshop. Two stage pump system coupled with a 7.5hp motor
maximises performance to keep running costs low compared to
single stage single phase models. 500ltr tank allows for longer
continuous air tool operation and less start ups so using less power,
saving on running costs. Pumps feature heavy duty full cast
cylinders, capped by alloy heads for improved heat dissipation and
long life. Heavy duty drive guards protect belt and flywheel, that is
designed to force air over the pump to aid cooling. Supplied with full
CE certification, test certificates and operating/maintenance manual.
