1.Super-heat adjusting

 

Take off cap and turn adjusting stem. Turn adjusting stem clockwise one round,increases super-heat 1.5℃.turn adjusting stem counter clockwise one round, reduces super-heat1.5℃.Set super-heat3.5℃ when exit factory.Static super-heat adjusting range is 2~8℃.

2.Installation

Valve inlet connects with receiver and outlet contects with the inlet of evaporator.Bulb should be equiped outlet of evaporator sense correct superheat.External equalization tube connects at the top side of suction line close the bulb.
