Disassembling

1. Disconnect the pump from the rest of the

system.

Warning:

Never unscrew the 4 screws marked

with coloured sealer.

3. Mount the guide bolt in the top hole.

2. Loosen all screws on the pump except

the three screws as shown above.

Note:

There is still water inside the pump.

4. Unscrew the remaining three screws

by using the combination wrench to turn

each screw a couple of rounds at a time so

the flange is removed as straight forward

as possible..
