16 Installation, Operating and Maintenance Instructions (Original Instructions)
ABS submersible sewage pump XFP 80C - 201G
9.5
Coolant changing (PE3 - version with cooling jacket)
The cooling system (seal chamber and cooling jacket) has been fi lled with glycol at manufacture. The water and
propylene glycol is frost resisting down to -15 °C / 5 °F.
A glycol change is only necessary:
At specifi ed service intervals (for details contact your local ABS Service Centre).
If the DI moisture sensor detects an ingress of water into the seal chamber or dry chamber.
After repair work that requires draining of the glycol.
If the pump is being taken out of service the glycol should be changed before storage.
In the case of extreme ambient temperatures below -15 °C / 5 °F (e.g. during transport, storage, or if the
pump is out of duty) the cooling liquid must be drained. Otherwise the pump may be damaged.
9.5.1 Instructions on how to drain and fi ll the cooling system
Loosen the plug screw (a) or (b), enough to release any pressure that
may have built-up, and re-tighten.
Before doing so, place a cloth over the plug screw to contain any
possible spray of glycol as the pump de-pressurises.
Secure a hoist to the lifting hoop. Tilt the pump to 45° with the drain
plug underneath.
Note:
because there is insuffi cient space to place a waste container
underneath the drain plug by the completion of step 5, the waste
must be drained into a sump.
Remove the plug screw and seal ring (a) from the drain hole.
Glycol will drain from the cooling jacket chamber.
When the fl ow stops, continue to gradually tilt the pump until
horizontal. This will drain the remaining glycol from the seal
chamber.
Note:
draining the glycol entirely with the pump in a horizontal
position would result in some glycol being retained in the cooling
jacket.
After the glycol is fully drained raise the pump into its upright position
and refi t the plug screw and seal ring (a).
Remove the plug screw and seal ring (b) from the fi ll hole.
Select the required volume of glycol from the quantities table and
slowly pour into the fi ll hole.
