1.1 ELECTRICAL SAFETY.
 WARNING! It is the user’s responsibility to read, understand and
comply with the following:
You must check all electrical equipment and appliances to ensure they
are safe before using. You must inspect power supply leads, plugs and all
electrical connections for wear and damage. You must ensure the risk of
electric shock is minimised by the installation of appropriate safety
devices. An RCCB (Residual Current Circuit Breaker) should be
incorporated in the main distribution board. We also recommend that an
RCD (Residual Current Device) is used with all electrical products. It is
particularly important to use an RCD together with portable products that
are plugged into an electrical supply not protected by an RCCB. If in
doubt consult a professional 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 all portable electrical
appliances, if used on business premises, to be tested by a
qualified Electrician at least once a year, using a Portable
Appliance Tester (PAT).

4. OPERATION
V-pump belt driven compressors, 200/270ltr. The pump features
heavy duty fully cast cylinders, capped by alloy heads for improved
heat dissipation and long life. Suitable for professional workshop
applications. The 3 cylinder pumps are powered by 415v 3ph
5.5/7.5hp motors. A precision continuously welded receiver tank
manufactured to meet Pressure Vessel Directive 2009/105/EC. Fitted
with fully automatic pressure cut-out switch and receiver drain valve.
Supplied with 4 anti-vibration mounts and fixings and with 4 core 2.5
metre flying lead.
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 4 AV mounts using the nuts, bolts and washers
supplied. (fig.8.)
3.5. The compressor should be operated on a flat surface, or one
that does not exceed 5° either transversely or longitudinally
and should be in a position that allows good air circulation
around the unit, (see 1000mm nominal perimeter).
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.4A and fig.7). Place a filter cover
over each threaded rod protruding from the back half of the
filter and secure each with a wing nut.
3.8. Check drain valve is closed (fig.6)
fig.4
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.

5.1. OPERATIONS TO BE CARRIED OUT AFTER THE FIRST
5 WORKING HOURS:
a) Check that all bolts/nuts are tight, particularly those
retaining the crank case and cylinder head.
5.2. OPERATIONS TO BE CARRIED OUT AFTER THE FIRST
50 WORKING HOURS:
b) Replace the lubricating oil - see para 5.5.
5.3. OPERATIONS TO BE CARRIED OUT DAILY:
a) Drain condensation by opening the valve located under
the tank (fig.5). Place a container under the valve and slowly
open the valve by turning counterclockwise.
5.4. OPERATIONS TO BE CARRIED OUT EVERY 100 HOURS
(or more frequently, if the compressor operates in a very
dusty atmosphere)
a) Check oil level and, if necessary, top up.
b) Remove the filter elements (See fig.8) and clean with
compressed air (Wear eye protection). DO NOT operate the
compressor without the filters as foreign bodies or dust could
seriously damage the pump.
c) Check for oil leaks
5.5. OPERATIONS TO BE CARRIED OUT EVERY 200 HOURS:
a) Replace the lubricating oil. For oil specifications see 5.7.
Remove the oil filler plug (see fig.4.B) then unscrew oil drain
plug (see fig.4) and drain the oil into a container.
Drain when the compressor is hot so that oil drains rapidly
and completely. Incline compressor to ensure complete
drainage.
Replace oil drain plug and refill through the oil filler
aperture. Do not overfill. Replace oil filler plug.
b) Check the automatic cut-out at max. pressure and the
automatic cut-in at 2bar below.
WARNING! Never mix different oils and DO NOT use
non-detergent/low quality oils as the compressor may be
damaged.
WARNING! Dispose of waste oil only in accordance with
local authority requirements.
fig.6
In order to keep the compressor in good working condition,
periodic maintenance is essential.
WARNING! Before performing any maintenance
operation, switch off the compressor, disconnect from

4.3. STARTING THE COMPRESSOR.
4.3.1. Your compressor is fitted with two push buttons for on/off
switching. To turn the compressor on push the green "on"
button. To turn the compressor off push the red button "off"
downwards. (See fig.5)
4.3.2. Check that the on/off switch is in the “off” position.
4.3.3. Plug mains lead into mains supply and start the compressor
by pushing the green "on" button (fig.5) downwards.
4.3.4. Leave the compressor running with no air line or tools
connected. Make sure that the pressure in the tank rises and
that the compressor stops automatically when the maximum
pressure is reached. This value is written on the specification
plate and may take in excess of 5 minutes.The compressor
will now operate automatically. The pressure switch (fig.5)
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 red "off" button (fig.5)
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.
NOTE: 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.
Should the pressure in the main tank exceed the pre-set
switch (fig.5) maximum, the safety valve (fig.1) will activate.
WARNING! For this reason DO NOT tamper with, or
adjust, the switch or safety valve.
