If the evaporator is supplied with pipework tails to connect the field pipework to the
Refrigerated Display Cabinet (i.e. the tails are installed from the ball valve connection on the
top or underside of the display cabinets). The length of liquid line pipework between the
connection point and the inlet of the expansion device MUST be the correct pressure rating.
