1. SAFETY

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.
You must also read and understand the following instructions concerning electrical safety.

Ensure that cables are always protected against short circuit and overload.
Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that none are loose.
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 at right.
❌ DO NOT use worn or damaged cables, plugs or connectors. Have any faulty item repaired or replaced immediately by a competent electrician.
It is recommended that this device is wired directly to a fused isolator switch. If, however, a plug is fitted, the following applies:

Fit a new plug according to the following instructions (UK only).

Connect the GREEN/YELLOW earth wire to the earth terminal 'E'.
Connect the BROWN live wire to the live terminal 'L'.
Connect the BLUE neutral wire to the neutral terminal 'N'.
After wiring, check that there are no bare wires, that all wires have been correctly connected, that the cable restraint is tight.

Recommended fuse rating 13 Amp

SAC3203B is 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.

1.1.2. Wiring a BS 1363/A UK 3 Pin Plug.

⚠️ WARNING! If in doubt contact a qualified electrician.

Connect the GREEN/YELLOW earth wire to the earth terminal 'E'.
Connect the BROWN live wire to the live terminal 'L'.
Connect the BLUE neutral wire to the neutral terminal 'N'.
Ensure that the cable outer sheath extends inside the cable restraint and that the restraint is tight.

Sealey recommend that repairs are carried out by a qualified electrician.

1.2. GENERAL SAFETY

Familiarise yourself with the application and limitations of the compressor.
Ensure the compressor is in good order and condition before use. If in any doubt DO NOT use the unit and contact an electrician/service agent.
WARNING! Compressor must only be serviced by an authorised agent.
DO NOT tamper with, or attempt to adjust, pressure switch or safety valve.
Before moving, or maintaining the compressor ensure it is unplugged from the mains supply and that the air tank pressure has been vented.
Maintain the compressor in good condition and replace any damaged or worn parts. Use genuine parts only. Unauthorised parts may be dangerous and will invalidate your warranty.

SAFETY (Continued)

Read the instructions relating to any accessory to be used with this compressor. Ensure the safe working pressure of any air appliance used exceeds compressors output pressure. If using a spray gun, check that the area selected for spraying is provided with an air change system/ventilation.
Ensure the air supply valve is turned off before disconnecting the air supply hose.
To move a transportable compressor use the handle only.
DO NOT attempt to move the compressor by any other means.
Use the compressor in a well ventilated area.
Ensure the compressor is placed on a firm surface.
Keep tools and other items away from the compressor when it is in use.
Keep area clean and clear of unnecessary items.

WARNING! The air tank is a pressure vessel and the following safety measures apply:

❌ DO NOT tamper with the safety valve.
❌ DO NOT modify or alter the tank in any way.
❌ DO NOT strap or weld anything to the tank.
❌ DO NOT subject the tank to impact, vibration or to heat.
❌ DO NOT allow contact with abrasives or corrosives.
Drain condensation from tank daily and inspect inside walls for corrosion every three months and have a detailed tank inspection carried out annually. The tank shell must not fall below the certified thickness at any point.

WARNING! If an electrical fuse blows, ensure it is replaced with an identical fuse type and rating.

When not in use, store the compressor carefully in a safe, dry, childproof location. When the compressor is not in use it should be switched off, disconnected from the mains supply and the air drained from the tank.

1.3. INSPECTION OF PRESSURE TANK BOTH INTERNAL AND EXTERNAL

Under the Pressure Systems Safety Regulations 2000 it is the responsibility of the owner of the compressor to initiate a system of inspection that both defines the frequency of the inspection and appoints a person who has specific responsibility for carrying out the inspection.

4. ASSEMBLY

Unpack the product and check contents. Should there be any damaged or missing parts contact your supplier immediately. Refer to attached parts list.

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.

4.1. WHEEL ATTACHMENT

Assemble the wheels and swivel castor using the nuts, bolts and washers supplied ([Figure 1]).

4.2. ATTACH THE FILTERS

Screw the filter unit into the port openings in each head as shown in ([Figure 3]).
Place a filter cover over each threaded rod protruding from the back half of the filter and secure each with a wing nut ([Figure 4]).

5. OPERATION

⚠️ WARNING! Ensure that you have read, and fully understood and apply Section 1 Safety Instructions.

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.

Confirm that the mains voltage corresponds with the voltage shown on the compressor data plate.
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 ([Figure 2]), and should be in a position that allows good air circulation around the unit, 1000mm nominal gap.
Before using the compressor check the oil level by referring to the oil sight glass ([Figure 3]). 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 6.7.
To top up undo filler cap ([Figure 3]), top up oil level to required level, then replace filler cap.
Take care when selecting tools for use with the compressor. Air tool manufacturers normally express the volume of air 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.

5.7. STARTING THE COMPRESSOR.

Your compressor is fitted with a push/pull type ON/OFF button to turn the compressor "ON" pull the ON/OFF button upwards. To turn the compressor "OFF" push the ON/OFF button downwards ([Figure 3]).
Check that the ON/OFF button is in the "OFF" position and the regulator dial ([Figure 5]) is closed (Zero '0' bar).
Plug mains lead into mains supply and start the compressor pulling the ON/OFF button ([Figure 3]) upwards.
Leave the compressor running with no air line or tools connected, and regulated pressure gauge ([Figure 5]) set to maximum pressure (fully clockwise). Make sure that the pressure in the tank rises and that the compressor stops automatically when the maximum is reached. This value is written on the specification plate and shown on the direct pressure gauge ([Figure 5]). This may take in excess of 5 minutes. The compressor will now operate automatically.

The pressure switch ([Figure 6]) 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.

Stop the compressor by pushing the ON/OFF button ([Figure 3]) 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.

5.7.6. The output pressure is regulated by the pressure regulator ([Figure 5]). Turn the pressure regulator dial clockwise to increase pressure and counter-clockwise to reduce it.

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 direct pressure gauge ([Figure 5]) indicates the pressure inside the main tank. The regulated pressure gauge ([Figure 5]) indicates the pressure supplied to the air equipment.

Should the pressure in the main tank exceed the pre-set maximum, the safety valve ([Figure 3]) will activate.

WARNING! For this reason DO NOT tamper with, or adjust, the pressure switch ([Figure 6]) or safety valve ([Figure 3]).

The compressor is fitted with a trip reset button, located on the side of the connection box on top of the motor ([Figure 3]). Should the trip activate, leave for 1 minute before pressing the button to reset. For possible causes of trip activation see section 6 Troubleshooting.

6. MAINTENANCE

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 electricity supply and release all air from the tank.

IMPORTANT!

Failure to carry out maintenance tasks may invalidate the warranty on your compressor.

[Figure 8]

6.1. 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.

6.2. OPERATIONS TO BE CARRIED OUT AFTER THE FIRST 50 WORKING HOURS:

B: Replace the lubricating oil.

6.3. OPERATIONS TO BE CARRIED OUT DAILY:

A: Drain condensation by opening the valve located under the tank ([Figure 7]). Place a container under the valve and slowly open the valve by turning counter clockwise.

6.4. OPERATIONS TO BE CARRIED OUT EVERY 100 HOURS

NOTE: 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 ([Figure 4]) 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.

6.5. OPERATIONS TO BE CARRIED OUT EVERY 200 HOURS:

A: Replace the lubricating oil. For oil specifications see 6.7. Remove the filler cap ([Figure 3]) then unscrew the drain plug ([Figure 3]) and drain the oil into a suitable waste oil container. Drain when the compressor is hot so that oil drains rapidly and completely. Incline compressor to ensure complete drainage. Replace drain plug and refill through the oil filler aperture. DO NOT overfill. Replace filler cap.
B: Check the automatic cut-out at maximum 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.

6.6. OPERATIONS TO BE CARRIED OUT EVERY 500 HOURS:

A: Replace air filter ([Figures 1] & [Figure 4]).
B: Check all tube fittings and electrical connections.

6.7. OIL

Recommended oil for compressors, suitable for room temperatures ranging from +5°C to +25°C.

SEALEY CPO or equivalent SAE 40 compressor oil. Room temperature below +5°C: SAE 20 compressor oil.

IMPORTANT WARNING

- Air contaminants taken into the compressor will affect optimum performance. Example: Body filler dust or paint overspray will clog the pump intake filter and may cause internal damage to pump/motor components.

WARNING! Any parts damaged by any type of contamination will not be covered by warranty.

6.8. Inspection of pressure tank both inside and out.

Under the PRESSURE SYSTEMS SAFETY REGULATIONS 2000 it is the responsibility of the owner of the compressor to initiate a system of inspection that both defines the frequency of the inspection and appoints a person who has specific responsibility for carrying out the inspection.
