Repair Rc 5 - vacuubrand RE 2 Instructions For Repair

Repair RC 5

Before starting repair, isolate the pump and other components from the vacuum sys-
tem and the electrical supply so that they cannot be operated accidentally. Allow the
pump to cool, so that it is at safe temperature for skin contact.
Before starting maintenance, wait two minutes after isolating the equipment from
mains to allow the capacitors to discharge.
