5.4 Plumbing Considerations
When planning the plumbing for the unit, please take the following into account:

Whenever possible, limit the number of bends in pipework.

The pipework must be clear and free from debris and blockages.
Pipework should be hot flushed before the unit is connected. Failure to
observe this precaution will invalidate the warranty.

Pipework must be pressure tested for leaks and this must be
carried before the unit is connected to avoid damage to the unit. Failure
to observe this precaution will invalidate the warranty.

It is highly recommended that a suitably sized buffer tank be
installed between the unit and the heating distribution system. Please
consult your installer or ESP when considering this system design
point – the right sized buffer tank can make a significant difference to
the economy and efficiency of the unit and the heating effectiveness.
6.0 Hydraulic Connection
6.1. Expansion vessels.
An expansion vessel must be installed where the heating system is unvented. The
size of the vessel(s) must be determined by the installer
on site and take into
account the entire volume of water/glycol mix being heated including the volumes
contained in the Unit, the buffer tank, the distribution system, emitters and any
other system connected to the unit. For this reason, they are
not included as part
of the optional ASHP installation pack. Expansion vessels can, however, be
provided by ESP as an additional optional extra.
