Vaporizer Plate/Vaporizer Maintenance
The injector valve vaporizer plate is normally replaced by the customer
when the cassette collection box is replaced. If the vaporizer plate needs
to be changed at planned maintenance, this procedure should be
performed for the customer. See the section on “As Needed
Maintenance” in this chapter for detailed removal and replacement
procedures. The vaporizer bowl should be wiped with a clean, damp
cloth.
Replace Vacuum Pump Oil
Note
: Always change the pump oil while the pump is
warm to prevent condensation in the pump.
1. Using an 8 mm Allen wrench, unscrew and remove the oil fill plug
located at the top of the pump.
2. Remove the cap from the empty bottle in the kit. Place an oil
absorbing cloth on the floor inside the machine as close to the drain
valve hose as possible. Place the bottle on the cloth. Open the drain
valve, place the hose in the bottle and drain the oil.
3. When draining oil from a Leybold D16A pump, insert the funnel in
the empty bottle and place it on an oil absorbent cloth, under the
valve at the rear of the pump. Open the valve to drain the oil.
4. After the flow has stopped, close the drain valve. Make sure the main
circuit breaker is off before proceeding.
Note
: If the used pump oil is excessively dirty, flush out
the pump using clean oil.
5. Open a new bottle of pump oil and replace the cap with the oil filler
cap (red tipped). Remove the red tip and cut about 1/6 to 1/4 inch off
the cap tip so the oil flows freely.
6. Pour new pump oil (slightly less than one quart) into the oil fill port
until oil reaches the raised line at the top of the sight glass (the MAX
line on the Leybold D16A). DO NOT OVERFILL or attempt to
empty the oil bottle. Some oil may remain in the bottle when the
pump oil is at the specified fill level.
7.
Re-cap and dispose of the drained oil and the oil absorbent cloth
following standard hospital procedures.
