5.3 Transporting the Unit
When lifting the unit during installation and transportation, an 8
meter strap must be used and the unit protected by soft material
placed between the lifting strap and the unit to prevent damage.
(See picture below).
5.4 Plumbing Considerations
When planning the plumbing for the unit, please consider the
following points:

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 tested for leaks before being connected
to the unit. Pressure testing must be carried before the unit is
connected to avoid damage to the unit. Failure to observe this
precaution will invalidate the warranty.

There must be an expansion vessel included in the design
of the system. The correct sizing of the expansion vessel(s) must
be determined by the installer and must include the volume of
water/glycol in all distribution pipework, emitters, the buffer
tank, pipe work between the unit and the buffer tank and all
other volumes.

Automatic bleed valves should be fitted at the highest
