Fault Finding Chart; Disposal - Grundfos Rmq-A Montage- Und Betriebsanleitung

9. Fault finding chart

Note: Before the RMQ unit is lifted off the wall
bracket for fault finding or other work on the unit like
for instance emptying of tank, the unit must be set to
"Only". Wait 10 seconds before disconnecting the
unit from the electricity supply. It has now been en-
sured that the three-way-valve is set to mains water
operation.
Before starting work on the unit, the electricity supply must be switched off or the plug must be
pulled out. It must be ensured that the electricity supply cannot be accidentally switched on.

10. Disposal

Disposal of this product or parts of it must be carried
out according to the following guidelines:
1. Use the local public or private waste collection
service.
This is necessary to ensure that the pump is filled
automatically when started up again.
For removal and mounting of the unit, see section
5.1 Wall mounting .
Remedy
Slacken the counter nut of the float valve,
align the float valve and retighten the
counter nut.
Open a point of consumption (e.g. water
closet, tap) and let the pump run for ap-
prox. 1 minute. This is an attempt to flush
the impurities away from the valve. Set
the unit to the desired operating mode.
Check the level sensor, cable and termi-
nal block. Connect the leads again or re-
place the cable.
Check whether the two stripped wires
touch each other. If so, strip them again.
Replace the level sensor as soon as the
water level is no longer indicated cor-
rectly.
Check the water level in the collecting
tank and the installation of the level sen-
sor. Restart the system, see section
7. Control panel .
Align the float valve.
Check the mains water pipe to the float
valve and whether the float in the float
valve can move vertically up and down.
Pump out the sewage water and clean the
tank.
2. In case such waste collection service does not
exist or cannot handle the materials used in the
product, please deliver the product or any haz-
ardous materials form it to your nearest Grundfos
