When should I not open the unit?
Do not open the unit if the channels or even one of the channels is under pressure. Any attempt may cause bodily injury and/or irreparable damage. Also, do not stand in front of the cover during opening as residual liquid may cause bodily injury. For safety reasons, do not stand under a suspended cover.
