The exhaust air is discharged via the maintenance cover.
A maintenance cover with integrated exhaust air flange (G ¾ internal thread) is optionally available for this
purpose.
The discharge by means of a flexible hose or fixed pipe must be installed in such a way that no mechanical tension
is applied to the pump.
It must be ensured that the exhaust air can flow out without major counterpressure (cf. chapter 2.6).
In case of high exhaust air temperatures, the exhaust air duct must be designed in such a way that it does not pose
any danger.
6.3 ELECTRICAL INSTALLATION
DANGER
Danger to life from electric shock - Personnel qualification
DANGER
Danger to life due to defective, dismantled and manipulated protective devices
DANGER
Danger to life due to unexpected start-up
NOTE
For a description of the safety instructions, see Chap. 2.9
The electrical installation of the pump shall comply with the requirements of Directive 2006/42/EC and EN
60204:2019.
If the pump is integrated into a control system, it must be ensured that the pump does not restart automatically after
an undesired voltage drop. The measures against unexpected start-up according to DIN EN ISO 14118:2018-07 must
be implemented. This also applies after a shutdown following an emergency stop.
The following points must be observed when installing the pump:
• The pump may be operated with a maximum of 60 start/stop cycles per hour.
• The supply line of the pump must meet the minimum requirements of the state of the art
