Vessel Draining/Refilling; Decommissioning, Dismantling - Wilo Sinum Einbau- Und Betriebsanleitung

8.1. Vessel draining/refilling.

If draining of expansion water in the main vessel
or auxiliary vessels is necessary, please consider
the following order of actions:
• Record the actual volume level (%) as shown on
SPC control unit display.
• Switch the control unit OFF.
• C lose the lockshield valves on the expansion pipe
(system inlet and outlet) and on the connecting
array (vessel inlet, outlet)
• Close the isolating valve at the top-up connec-
tion.
• Carry out the required work on the vessel (drain,
service, repair etc.).
• Switch the control unit ON reset to start menu
(overview of menu options; menu line 11-5-7)**
and run start menu procedure (overview menu
options; menu-line 9...9-9)***.
• F ill the main vessel and (if applicable) the auxiliary
vessels. The self-adjusting volume level can be
monitored in the display of the control unit and
the filling process should be interrupted at re-
aching the previously recorded target value.
Note: when a refill bigger than the default setting
for minimum vessel filling volume is required
(6%), please switch off the de-aeration function
(overview menu options; menu-line 8-5-1). The
filling should preferably take place over the vessel
connection valve (marking). If both the main and
auxiliary vessels need filling, open the lockshield
valve on each vessel connection (flow and return).
Make sure that the volume level detection is
made by using the volume sensor of the main
vessel.
• Disconnect the filling equipment.
• Open all previously closed valves (seal) and bleed
the pump(s).
• Optionally the de-aeration function can be swit-
ched ON again.
• The operational mode has been restored.
)** T here are 3 questions in this menu item.
Only when these are confirmed, the reset
takes place.
)*** A t the moment of restarting the system
some logical errors may arouse that are
self-acknowledging or acknowledged.

9. Decommissioning, dismantling

At the end of the of the service life or at planned
shut-down of the equipment, please make sure
that the module is separated from the power sup-
ply. The hydraulic system connections and top-up
connections should be closed off.
Caution: water areas should first be made pressu-
reless and empty when the destination or re-use
of system water should be designated in confor-
mity with the applicable rules. This water may be
treated, contain anti-freeze or other additives.
The designation of further processing of the
construction parts should be carried out in ag-
reement with the required waste management
service provider.
