PLUG & MAINS POWER SUPPLY

!  

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 all portable electrical appliances, if used on business premises, to be 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 on right.

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. When an ASTA/BS approved UK 3 pin 13 amp
plug is damaged, cut the cable just above the plug and 

dispose of the plug safely.

Fit a new plug according to the following instructions

(UK only - see diagram on right).

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.

1.1.10. If an extension reel is used it should be fully unwound before connection. A reel with an RCD fitted

is preferred since any appliance plugged into it will be protected. The cable core section is important and should be at least 1.5mm

2

, but to 

be absolutely sure that the capacity of the reel is suitable for this product and for others which may be used in the other output sockets, we 
recommend the use of 2.5mm

section cable.

WARNING!

If the heater is used for prolonged periods at maximum power, ice may form on the propane cylinder. This is due to 

excessive evaporation. In such a case DO NOT use the heater to de-ice the cylinder.

WARNING! 

Air contaminants taken into the heater will damage the unit, cause health problems and safety issues.

Example: Body shop filler dust and overspray dust will clog the burner diffuser, contaminate the combustion chamber and damage the 
internal parts of the heater. If contaminants are present the heater must be supplied with ducted clean air.

Please note that any parts damaged by filler dust or overspray dust will not be covered by warranty. Additionally a cleaning 
charge will be made for any heaters damaged by filler dust or overspray dust.
