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 

fi

 tted 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 

fi

 tted, the following applies:

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

 

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 restraint is tight.

1.1.1. 

  

Model No’s SAC3153B and SAC3203B 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.

1.1.2. 

  

Wiring a BS 1363/A UK 3 Pin Plug.

WARNING! 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) 

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 quali

fi

 ed 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.

Recommended fuse rating
