Vacuum Pump; Checking Operation Of Mechanical Back-Ups; Exhaust Vessel / Delivery Pot (Emptying); Changing The Hose With Vacuum Applied - MIL'S HOSPIVAC G EVISA E350.R Manual De Operación Y Mantenimiento

11.2. Vacuum pump

IMPORTANT:
For this operation, use all necessary protective measures (gloves, mask, overalls etc.)
then destroy contaminated consumables (antibacterial cartridges, condensates etc.) in
according with that country's applicable laws (regulation incinerator).

11.3. Checking operation of mechanical back-ups

Check with relevant authority that this test is suitable for the activity and architecture of
the building in which the network is installed. This action will trigger an alarm.
A mechanical back-up vacuum switch is placed in parallel with the control unit.
 Set the general switch to "O".
 Remove the connector O1 to O8 (PROCOM-2) or 1 to 10 (CYCLIC 2020) in order to withdraw the piloting
part of the pumps by the chart and to keep the display of the pressure.
 Reduce the vacuum in the receiver, the pumps should start up at around –450 mbar and stop at around
-800 mbar with PROCOM-2 and CYCLIC 2020.
 Once the check has been completed, set the general switch to "O", put the connector back in place and
then reset the general switch to "I".

11.4. Exhaust vessel / delivery pot (emptying)

IMPORTANT:
For this operation, use all necessary protective measures (gloves, mask, overalls etc.)
then destroy contaminated consumables (antibacterial cartridges, condensates etc.) in
according with that country's applicable laws (regulation incinerator).
This operation should, whenever possible, be carried out with the pumps switched off.
 Unscrew and empty the vessel.
Note: if there is an abnormally high quantity of oil, check the condition of the vacuum pump exhaust filters.

11.5. Changing the hose with vacuum applied

To change the hose, proceed methodically in order to avoid interrupting vacuum production and always
remember to isolate the unit from the rest of the network. If the hose is located on the suction side of the
pump, the pump must be stopped. The non-return valves are located in such a way that they will
automatically isolate the network when a hose is being changed.
Respect the minimum curve. The hose must never be installed stretched.
Interrupting the Rilsan connection between the network and the electrical cabinet will cause a leak that will
be compensated for by operation of the vacuum pumps during the changeover time (this connection does
not have a check valve or an isolation valve).

11.6. DN80 isolating valve

Loss of tightness of this valve will lead to a leak when breaking a hose connection.
11.7. Validation of sensor measurements – vacuum gauge
Connect the electronic calibrating vacuum gauge to the bleed valve of the receiver and check the sensor
regulation and the mechanical vacuum gauge.

11.8. Checking operation of the network alarm

Disconnect the 'rilsan' pipe from the network alarm sensor C2V to make a vacuum drop; the low network
alarm will be triggered at –370 mbar.
12.

PRECAUTIONS WITH THE NETWORK

The components of the vacuum unit are not designed to resist an overpressure coming from the network,
for example during the cleaning and pressure tests phases.
It is the same for the lowest level drip pot placed at the various points of the network.
It is imperative to be isolated from the network during maintenance operations.
The hydrogen peroxide can release from oxygen and under certain conditions, to cause an increase
abnormally high of the pressure.
13.

TRAINING

In order to ensure perfect aptitude in the use of the vacuum plant for medical use, the MIL'S Company
offers its own training for the use of this equipment. It is intended for users and technical personnel
working on or near the vacuum plant for medical use.
14.

CLEANING

14.1. Units cleaning
If the units system requires cleaning, use a soap solution and a clean cloth.
Then wipe well with a dry cloth.
For disinfection, use swabs soaked in a disinfectant solution.
Frequency: as required.

14.2. Network cleaning

When cleaning a network with a cleaning solution or disinfectant, we must be vigilant.
The solution mixed with the organic material present in the network, could lead to an extremely rapid and
significant pressure for progress in specific components (jars low point, for example) which can lead to an
explosion of them.
15.

ELECTROMAGNETIC COMPATIBILITY

The vacuum unit with PROCOM2 or CYCLIC 2020 automate needs special precautions regarding EMC. The
vacuum unit with PROCOM2 or CYCLIC 2020 automate has to be installed and put into service according to
the EMC requirements joined in the following tables.
 See Annex

E600.R
Check with relevant authority that this test is suitable for the activity and architecture of
the building in which the network is installed. This action will trigger an alarm.
The suction through network of hydrogen peroxide or all other having the same
properties is completely proscribed.
Do not use corrosive product
