3.1
Operating Cycle
Make sure the on/off switch is OFF (O), and the unit is positioned safely (see 2.2), before
connecting to the electrical supply.
Switch the on/off switch to ON (–). The switch will glow green and the unit will operate
immediately.
Allow the unit to run for 5-10 minutes before using.
This paragraph applies only to the current (white) model.
If the unit is used for long periods it will occasionally enter a cooling cycle in which the air flow
increases for around 15 minutes, after which it will resume normal operation. During this period
the temperature of the hot air will be reduced.
Switch the unit off after use.
3.2
General Operating Notes
Excessive continuous use can shorten the life of the unit.
The ambient temperature can affect the frequency with which the cooling cycle operates.
3.3
Operator Safety
The operator should read this manual and observe all the recommendations in it.
Do not open the unit, insert anything into it, or allow fluids to enter it. Do not operate the unit with
wet hands.
Avoid burns caused by touching the nozzle or holding a hand in the hot air stream. Be careful even
when wearing gloves, as burns can be caused by delayed heat transfer through a glove.
Do not use the unit in the presence of potentially explosive vapour: use of the safe-air near volatile
materials can be dangerous.
The Safe-Air is internally fused, and the current (white) models also feature a thermal trip and
thermal fuse to protect the operator from electrical shock and the unit from excessive heat build
up. The supply lead is fused at the plug.

General Maintenance
Do not open the unit or attempt repair. See section 4.3 before replacing the plug fuse.
If repair is required please contact Thermal Engineering Services: contact details are at the end of
this manual. Please quote the serial number from the base of the unit.
4.2
Cleaning
Switch off and disconnect the unit before cleaning.
Clean by wiping with a damp cloth. Do not use organic solvents.
Do not allow water to enter the unit. Allow it to dry before reconnecting it.
4.3
Fuses
The line plug contains a 3 Amp 25x5mm BS standard fuse; this protects the supply lead. Do not
replace this fuse with one of a higher rating.
The Safe-Air contains a 2 Amp fuse on the live side; this protects internal wiring.
Failure of a fuse indicates a fault. Please contact Thermal Engineering Services if the unit does not
work when switched on.
