After the pipieline connection is done,use a leakage inspection device or soap to carefully check
if there is any leakage at the joints.This is an important step to ensure the quality of installation.
If refrigerant gas leaks, ventilate the area immediately. Toxic gas may be produced if refrigerant
gas comes into contact with fire.Never directly touch any accidentally leaking refrigerant. This
could result in severe wounds caused by frostbite.
Bending the copper pipes
DO NOT USE a metric pipe bender as the pipes are imperial diameters and this will crush
them as they will spread and be flattened! Do not use any internal bending springs as you will
damage the pipe internally by chafing the copper.
The copper pipes take a little patience and care to bend suitable curves without crushing or
kinking. There are 2 pipes; one is smaller than the other. The smaller is fairly soft and will bend
reasonably easily to a gentle curve, be careful not to kink the pipe.
All larger pipes require a bit more patience. First of all, cut around the insulation where you
would like the bend and slide apart the insulation so you can see the copper pipe itself. Then
working from the centre position of your required curve, placing your thumbs either side (much
like snapping a stick) be careful to ‘feel’ the pipe bending and stop as it starts depress. Move
along slowly bending the pipes round in a controlled manner.
