Maintenance / Service - Zehnder Pumpen SWH 100 Betriebsanleitung

Place of installation:
Must be free of frost and on level ground.
Connections:
Intake connection (optimal 3 pcs.), types SWH 100/190
- Nipple to connect a hose, diameter ¾"(20mm)
- Gasket at the top to the connect pipes, diameter 40mm with a spline end which alleviated the mounting of the intake
connecting(scope of delivery)
- The washing machine connection has to be slipped over the hose nipple!
- The pipe inlet connection with a diameter of 50mm for shower is located sideward at the container. It is locked with a dummy
plug. The inbuilt height amounts 80mm. It is usable from booth sides through turning the box. To connect a shower, make
sure that the shower tray is set high enough to create sufficient drop (min. 15 cm).
- Intakes not used have to be sealed and blanked off!
Connections of pressure pipes:
There is a back draft damper built in the lifting unit. The pressure pipe has a thread socket G1 ¼" FT at its end. Care should be taken not to
over tighten plastic fittings! Please take care that the screwed connection of the pressure pipe does not block the port for the back
draft damper. To facilitate maintenance work on the lifting system and to reduce structure-borne sound transmission, we recommend
connecting the pressure line to the permanently installed pipeline with a flexible connection hose. Please ensure the non return valve is fitted
to the system discharge port.
Ventilation and odour prevention:
This lifting unit is designed with active carbon filter assignment and may not need any separate ventilation. Self evident, it is possible to
install separate ventilation pipe with a diameter of 40mm. For this case remove the integrated valve- filter (carbon filter, valve insert, ball)-
unit.
Commencement of operation:
Before starting up check all pipe connections for correct mounting, please. Now plug the SWH unit into an electrical outlet and check the
function by letting water go into the container. At this point, check the tightness of the intake. After the refloating of the float switch the
pump will be switched on automatically. The discharge pipe tightness has to be checked for leaks while pump is operating. The pump will be
switched off automatically by the float switch when the water level is at its lowest. Water must not run back from the pressure pipe to the
container. If, after switching off the pump to crashing noises of this check valve is located on the pipeline design of the penstock. By
installing an additional check valve in a vertical section of the penstock can avoid the flapping noise.

6. Maintenance / Service

Always disconnect from power before servicing!
Service and repair at electrical parts of the pump (cable, motor) has to be done by authorised service- companies
or producer.
In case of very low temperatures and in any case before the first frost the pump must be removed from water.
Empty the pump and store it in a place where it is protected from frost.
The lifting unit has to be cleaned regularly. For checking and cleaning the lifting unit disconnect the pressure pipe and the intakes from the
cover. Then detach the clips from the cover. After this the cover with pump has to lift up. The container, the intake strainer, the float switch
and the ventilation bore hole at the pump have to be cleaned to avoid malfunction and clogging by solids and by contamination.
In case of using washing machines without strainer the lifting unit has to be cleaned in shorter intervals, and especially the ventilation bore
hole, float switch and the intake strainer.
