Testing The Safety Valve On The Cap; Testing The Vacuum Tightness Circuit; Filling The Cooling System With New Coolant - Sam Samx Drainer Handbuch

III. Testing the safety valve on the cap
09
PLACE THE CAP ON THE TEST DEVICE ON THE MACHINE
> Check the safety valve is working properly and set at the right pressure. To do this, screw the cap onto the adapter provided,
and turn the control to the left to position "T". The valve must trigger at between 1.6 bar and 1.8 bar, pressure which can be
checked using the pressure gauge on the right.
IV. Testing the vacuum tightness circuit
10
CHECK THE TIGHTNESS OF THE SYSTEM
> Once the cooling system is empty, let the pressure stabilise at between -0.75 bar and -0.8 bar, the close the drainer valves,
check that the pressure does not go up over 0 seconds.
V. Filling the cooling system with new coolant
11
FILL THE SYSTEM
> Can be done at any time during the coolant draining and
cooling system filling procedure.
