Connections to the pneumatic network

7.4.1. Suction side
 For each vacuum pump, connect the suction hose between the suction flange of the vacuum pump and
the manifold. The isolating valve is fitted on the manifold.
 Install the anti-bacterial filter(s) FD1000 with the upstream and downstream isolating valves.
Strictly respect the passage direction in the filters: from outside to inside the cartridge
 Pneumatically connect the C1V sensor (regulation) and the back-up vacuum switch via a rilsan hose
from the box to the downstream side of the anti-bacterial filter.
 Pneumatically connect the C2V sensor (alarm) via a rilsan hose from the box upstream of the anti-
bacterial filter.
7.4.2. Exhaust side
The exhaust collector must be connected to a gas evacuation canalization, which leads to the outside of the
building, either via the façade or vertical duct (standard NF EN ISO 7396-1§ 5-7-8).
Beware of rainfall penetration or blockages caused by nests or other obstacles.
 Connect the exhaust of each vacuum pump to the exhaust collector using hose.
 An exhaust vessel must be fitted at the lowest point of the exhaust collector.
 The exhaust must be positioned so that it is not sucked back in by another system who can present a
risk (Compressor suction for medical air production or O2 concentrator supply, ventilation air.).
 It must not be positioned in a zone that can receive people.

COMMISSIONING

HOSPIVAC systems are used only for suction of non-aggressive gas, with less than 22% of
oxygen gas.
It is not recommended to use HOSPIVAC to exhaust anaesthetic gas (AGSS system) with
the risk of self-ignition.
IMPORTANT: Mechanical vacuum switches having relative value measurements are used,
and set taking the altitude at which they are installed into account. For details on this
procedure, refer to the § 5.

8.1.
Read the attached vacuum pump start-up and maintenance manual prior to starting up the equipment.
It should be noted that each pump has been factory filled with synthetic oil MV99S, special designed for
vacuum pumps.
The oil level of each pump must be checked prior to operation.
Set the general switch GS (red/yellow knob) to O (Off).
8.2.
Open the main receiver bleed valve and shut off the network outlet valve.
Set the main switch (MS) to I (On): all vacuum pumps start.
Immediately check the direction of rotation of pumps. An arrow affixed to the pump indicates the correct
direction of rotation. If turning in the wrong direction, immediately stop the unit using the main switch
(MS) and inverse the two wires at the required pump's contactor or at the motor.
Close the main receivers bleed valve and open the network outlet valve.
Switch on the vacuum unit resulting in a steady increase of the depression within the network.
Check all connections for leaks.
To check that the chosen set up is operating correctly:
 Isolate the system from the network by closing the outlet valve,
 Induce a controlled leak by partially opening the bleed valve of the main receiver.
 Once this check has been carried out, make sure the bleed valve is properly closed and open the
network outlet valve.
For more detailed information concerning the control mode, consult the PROCOM-2 or CYCLIC 2020
manual.
8.3.
The valve is equipped with an electric motor which spends approximately 15 seconds to open and to close
itself.
When the pump is off, the isolating valve is in closed position and it opens when the order is given to the
pump to start.
At the stop request, the isolating valve closes and the pump continues to operate during the time delay T A,
B, C... according to the electrical diagram.
