If the M15 pump and the Y1 valve should start to vibrate, i.e. switching on and off con-
stantly, disconnect and reconnect the connector of the Y1 valve several times until the
M15 pump runs smoothly.
Alternately vent each circuit of the cooling unit (OT and Litho) for approx. 10 minutes to
remove the air. The flow rate can be increased to 40 l/h (W11.R5).
During venting, move the shock wave head several times from the park position into the
therapy position and back again.
•
If no more air bubbles can be seen in the
flow rate meter, set R5 on board W11 to a
flow rate of 25 ± 3 liters.
(Refer to figure on the right). If necessary,
set switch S1 of the flow rate meter to
20 ltr.
•
After the filling process terminates,
LED V3 on board W11 must light up.
•
Check the S1 flow rate switch.
Decrease the flow rate slowly with poten-
tiometer R5 on W11 until a flow rate of
20 ltr. is displayed. LED V3 is no longer
illuminated.
Subsequently, reset the flow rate to
25 ± 3 l .
After venting the system, check the voltage at measurement point X3 (or MP.X2.3) of
board W11. (0 Volts on board D1 at measurement point X3).
This voltage must not change by more than 50 mVolts within 10 minutes. The cooling unit
must be switched off during this check.
NOTE
•
Tighten the red cap of the vent valve.
