NOTE: In the factory settings, the alarm signal triggers when the tank filling level is about
200 mm (single-pump system L-V) or 250 mm (double-pump system L-2V) above the
unit's installation surface. This is to be observed when drainage fixtures are also to be
secured with the unit's alarm which lie relatively low (e.g. floor drains).
8 Commissioning
It is recommended to have commissioning carried out by Salmson after-sales service.
8.1 Checking the unit
CAUTION! Risk of damage!
Dirt and solids as well as incorrect commissioning can lead to damage to the unit or
individual components during operation.
• Before commissioning, clean the entire unit to remove contaminants, particularly
solids.
• Observe the installation and operating instructions of the switchgear and the accesso-
ries.
Commissioning may only be carried out when the relevant safety regulations, VDE regula-
tions as well as regional regulations have been met.
• Check for the presence of and proper versions of all required components and connections
(inlets, discharge pipe with check valve, ventilation via the roof, floor fixation, electrical
connection).
• Checking the settings of the venting screw of the non-return valve.
• Check the level control for perfect mechanical condition. Open the maintenance cover and
check the float switch in the tank for ease of movement and a firm hold of the float to the
rod. Seal the screw lid tightly again.
8.2 Commissioning
• Switch on the unit at the main switch.
• Open the check valves.
• Fill the system via the connected inlet until each pump has pumped out at least once and
the pressure pipeline is completely filled.
With the pressure pipeline filled and the inlet closed, the filling level in the tank must not
rise. If the filling level continues to rise, the flap of the non-return valve is leaky (must
check the flap and the position of the venting screw).
For a test start-up, the "manual mode" button on the switchgear can also be pressed
before reaching the switch-on level in the tank.
• Check the unit and pipe joints for impermeability and perfect function (switch the pump
on and off).
8.2.1 Switchgear settings
The switchgear is pre-set in the factory. For the rotation direction monitoring, adjustment
of the DIP switches and other settings, see the installation and operating instructions of
the Salmson EC-Drain LS switchgear.
• Compare the default value of the motor current with the specifications on the name plate
of the motor and, if necessary, correct the settings.
CAUTION! Risk of damage!
If the venting screw with sealing nut is not in
the required position, this can lead to damage
on the flap and unit, as well as to high noise
development (Fig. 11).
