FSXNH modular
2-pipe or 3-pipe
Set Free VRF 2-pipe heat pump or 3-pipe
heat recovery available from a single unit
to adapt to customer requirements. Each
outdoor unit is lightweight and modular
which – combined with long piping runs
and improved height difference – means
Set Free VRF can meet any design brief.

Features and Benefits

Awarded Enhanced Capital
Allowance (ECA) scheme status

t Cooling capacities from 14kW to 100kW
t Heating capacities from 16kW to 112kW

™

The ECA Scheme is part of the Government’s programme of
measures to manage climate change which gives businesses tax
relief for investing in energy-efficient, accredited products - making
it possible to claim a 100% first year capital allowance against the
taxable profits in the period of investment (rather than claiming on
a reducing balance).

t Market-leading energy efficiency
t Low noise – select from 3 settings with up to 8dB
noise reduction
t 2-pipe heat pump or 3-pipe heat recovery
(requires CH Box)
t Connectable to up to 59 system free indoor units
(dependant on model)

Flexibility built in

t Total maximum pipe run of 1000 metres

Hitachi’s System Free indoor units can
be combined with outdoor units from
either our Utopia splits or Set Free VRF
ranges for ultimate flexibility.

t Japanese Energy Efficiency and Conservation
Award 2013 winner.

Changeover Boxes
Hitachi Changeover (CH) Boxes are compatible with
the Set Free heat recovery systems and enable a
change from 2-pipe heat pump and 3-pipe heat
recovery on our FSXN and FSXNH products as
customer requirements change. Installations are
quick and simple as the strainer is installed at the
manufacturing stage and piping connections are
reduced from 5 down to 3. The electrical box can
be positioned at either side of the CH Box for
easier servicing.
