45. PACKING OF DEFECTIVE UNITS

Particular attention must be paid to the packing of a replaced defective unit to en-
sure during its return to the distributor that it will not be damaged in transit.
When the replacement unit is supplied cased, careful note should be taken of the
manner in which it is packed, to ensure that the form of packing adopted, i.e. the
use of wood bracing and cardboard pads, is used when the defective unit is packed
into the case.

Structural distortion, particularly with the smaller units not having an angle iron
f rame, can easily occur if the case containing the unit is roughly handled and if
internal braces are not in position.
