4.1.1 Foundation
Install the pump on a vibration-free foundation. In case of wooden
floors use a small concrete foundation of approx. 225 x 225 mm
and 40 to 50 mm thick.

4.2 Pipes
Fig. 9 Solder flux causes damage to plastic parts
Fig. 10 Pipe connection to hot-water cylinder
Use 22 mm pipes to and from the pump.
• The expansion pipe from the hot-water cylinder should always
rise in order to prevent trapped air.
• The outlet pipe from the pump to the shower valve should rise,
where possible, to prevent trapped air.
• Pipes from the pump to the shower valve should go up and
over, rather than under floor.
• Do not fit any other outlets in the inlet pipes to the pump. See
fig. 12.
• Use dedicated supplies to hot and cold water.
• Avoid blanked-off pipes.
• Avoid restrictions in the flexible hoses.
• Secure down all pipes to minimise noise and vibration.

4.2.1 Hot-water cylinder connections
Connect the supply from the hot-water cylinder to the pump with a
dedicated supply.
Fit a surrey flange to minimise air in the hot-water supply to the
pump.
Use 22 mm pipe to ensure an adequate flow to the pump.
4.2.2 Cold-water supply
Connect the pump with a dedicated supply using 22 mm pipe
from the cold-water storage tank.
