Defrosting frozen pipes
Choose the Hook nozzle and fit
over the heat outlet. Always heat
from one or other end of the frozen
portion, not from the middle.
WARNING:
Do not attempt to
defrost PVC pipes. Always check
that it is a water pipe and not a
gas pipe. Do not heat a gas pipe.
Shrink sealing electrical cables
Choose the Hook nozzle and fit
over heat outlet. Select a heat-
shrinkable sleeve with a diameter
matching that of the workpiece.
Evenly heat the sleeve.
Welding plastics
Choose the Concentrator or
Deflector nozzle and fit over heat
outlet. The materials being welded
together must be of exactly the
same type of plastic. The areas
being welded must be clean and
grease-free. Heat the seam until the
plastic becomes tacky, then apply
the other surface.
WARNING:
Plastic can very
quickly change from being tacky
into becoming liquid. Beware of
burns from hot plastic. Do not
remove molten plastic from a
burn. Run under cold water and
seek medical advice.
Bending plastic tube
Choose the Hook nozzle and fit
over heat outlet. Turn the gun
upside down and place on it’s
stand so that it is resting on a
secure bench with the nozzle
pointing upwards; see picture
below. To avoid buckling or kinking
the tube, fill the tube with dry sand
and seal at both ends. Heat the
tube evenly by moving from side to
side and bend to required shape.
WARNING:
Protect hands from
heat.
Cooling
The nozzle of the heat gun can
become very hot during use.
Always allow
the heat gun
to cool after
use. Switch
off the heat
gun and
disconnect
form the
power supply.
Stand the heat gun upright as
shown to allow convection currents
to cool the nozzle.
To speed up the cooling time, set
the heat setting to the minimum and
run the heat gun for 2-3 minutes.
Always allow at least 30 minutes for
the heat gun to cool after switching
off.
Always make sure that the heatgun
cannot be pulled by the mains
cable whilst cooling.
