13 START-UP
Specific safety instructions for media being handled must be observed.
Before pumping a medium, the compatibility of materials of pump head, diaphragm and valves with the
medium must be checked (for pump materials: see technical data).
The following steps should be carried out before initial start-up:

The pump must not start against pressure or vacuum. When it is switched on the pressure in
the suction and pressure lines must be atmospheric. This must be so even when the pump re-
starts after the power has been cut off for a short period.

The maximum permissible operating pressure (see technical date) must not be exceeded,
even when the flow is restricted.

To prevent the maximum permissible operating pressure being exceeded, restriction or control
of the air or gas flow should only be carried out in the suction line.

If restriction or control of the air or gas flow is made on the pressure side ensure that the
maximum permissible operating pressure is not exceeded.

When the pump is at a standstill the inlet and exhaust must be at normal atmospheric pres-
sure.

Diaphragm and valve plates are the only parts subject to wear. Wear is usually indicated by a
drastic reduction in the pneumatic performance. When replacing parts proceed as described in
section 14.

Ambient conditions: see technical data.
In the following:

Push motor protection switch that the button is moving out.

Switch on mains power supply.
The total heating-up time is approximately 1 hour. After approximately 30 minutes the pump tempera-
ture exceeds the low-temperature alarm (30°C below rated value). After this another 30 minutes are
needed to reach the operating temperature.
The motor can be started after pushing the motor protection switch (button is moving in).
14 CLOSING DOWN
N O T E !
The area in which the pump is situated when not in use must be kept free of
frost at all times.
If the pump is putting out of action for a short time no particular measures need to be taken.
