WARNING:
Do not use silicone when assembling the
iSave. Do not reuse disassembled O-rings and
the shaft seal as they might be damaged.
Always use new O-rings.
Important:
It is essential that the pump is serviced in
conditions of absolute cleanliness. All
parts must be completely clean before
mounting.
Lubrication:
• To prevent seizing-up, lubricate all
threads.
• It is important to lubricate ALL parts
to be assembled with clean filtered
water (Especially all PEEK parts).
5. Assembling the
pressure exchanger
1. Lubricate the port flange and port plate
with clean filtered water.
Mount the port plate (brine) over the new
clips and pins on the port flange.
Make sure that the clips are below the
port flange surface.
3. Mount the lifting eye on the cylinder
barrel big shaft end and carefully lower the
cylinder barrel straight into the exchanger
housing using lifting equipment. (The
weight of the cylinder barrel is about 32
kg).
Afterwards remove the lifting eye.
WARNING:
If the cylinder barrel is dropped or
lowered too fast into housing, the
bearing in the Port flange might be
damaged. Replacement can only be
done at Danfoss, DK-Nordborg.
2. Check that the new small pin is still
placed in the port flange and place the
exchanger housing carefully over the
small pin.
