Installation and Operation
5.1
Unpacking
Carefully unpack the diaphragm pump.
Check the pump for:
Transport damage,
Conformity with the specifications of the supply contract (Model, electrical supply data),
Completeness of the delivery.
Please inform us without delay if there are discrepancies between the delivery and the con-
tractually agreed scope of delivery, or if damage is detected.
Please take note of the general terms of business of the manufacturing firm.
In case of a claim under warranty, the device must be returned in packaging that is
suitable for protecting it during transport.
5.2
Installation and Connection
1. Set the diaphragm pump on a flat and horizontal surface.
2. Remove the protective caps on the intake and exhaust ports.
3. Prepare the connections.
4. Connect electrically under compliance with the currently valid regulations described
in
chapters 1.7 and 2.2.
5. Connect the vacuum connector (DN 8 and/or DN 16 KF) to the intake port.
6. Connect the pressure pipe to the exhaust connection.
7. Connect the inert gas pipe to the hose nozzles.
The user must integrate suitable monitoring of the inert gas flow in the inert gas outlet
pipe. This must also be able to simultaneously detect a malfunction, and initiate suitable
actions to prevent possible damage.
5.3
Operation
Observe the basic safety instructions when using the pump.
Contents of the currently valid Operating Manual
Compliance with the classification limits stated in Atex-Directive
2014/34/EU
, including
the regulations governing the implementation.
Contents of the process sequences specified for the user
Compliance with the maintenance intervals or specification of these intervals by the user
in the case of special processes.
Regular inspection of the suction and pressure side connections for leaks.
Regular inspection of the pressure-side connection for blockages. Particularly if a central
air exhaust system has been installed. The max. outlet pressure of 1.5 bar absolute must
not be exceeded under any circumstances. On exceeding the diaphragm pump must be
switched off.
Inspection of the inert gas connections and the safety device as described
in chapter 5.2.
Deviations from the inert gas outflow must be detected. As the manufacturer, we recom-
mend a minimum inert gas flow of 20 l / h. A malfunction can be expected if this flow de-
viates by more than ± 10 percent during operation. The diaphragm pump is turn off,
where appropriate, to prevent ingress of pumped liquid in the crankcase. These malfunc-
tions may be: Interruption of the inert gas flow, diaphragm ruptures or other leaks
(see
also chapter 7).
