2.7.2. Different level installation
If the remote unit is installed higher up than the appliance
(fig.12), a siphon must be installed at each start or ascent
(a), every 1.8 metres of difference in level along the return
duct, and at each arrival (b).
If the remote unit is installed lower than the appliance, no
siphon is needed (fig. 11).

For water condensed units or units with heat recovery:
when choosing and installing water piping, follow the
local provisions and regulations concerning construc-
tions and safety standards. The installer must take care
of the mechanical coupling of connections having
dimensions appropriate for the system and make sure
that the water inlet and outlet connections agree with
the dimensional drawing and with the stickers on the
connections. The piping must be supported to reduce
the weight and tension on the connections. An inspec-
tionable filter which filters solid bodies must be installed
on the inlet pipe of the heat exchanger.
If noise and vibrations are critical, anti-vibration fittings
must be installed on the inlet and outlet water pipes of
the heat exchangers.
Length-adjustable piping must be installed, using
supports which allow it to slide and provided with
sufficient space near walls and other constraints.
If the heat exchangers of the blast chiller/conserver can
be shut off from the rest of the plant by means of valves,
these exchangers must be protected by adequate
safety devices as foreseen by the standard EN378-
2:2008+A1:2009 chapter 6.2.6.8.
