Connecting water
The water pipes are always placed on the product’s short
side, regardless of the air connection side of the product.
Connect the water pipes using push-on couplings or
compression ring couplings when the product is ordered
without valves. Note that compression ring couplings
require support sleeves inside the pipes.
Do not use solder couplings to connect the water pipes.
High temperatures can damage the unit’s existing soldered
joints.
Flexible connecting hoses for water are available for flat-
end pipes and valves, and can be ordered separately.
To avoid corrosion in the water circuit, the water quality in
the system water must be checked regularly.

Water quality
Swegon recommends water quality according to VDI 2035-2
for both the heating and cooling systems. In order to
maintain the oxygen content in the water below the levels
(<0.1mg/l) prescribed in VDI 2035-2, it is recommended
to install a vacuum degasser, particularly in the cooling
system where it’s more challenging to dissolved gas. It
is also important that the pre-pressure in the expansion
vessel is dimensioned according to EN-12828 for both the
heating and cooling systems and that regular checks are
made of the pre-pressure. The cooling and heating systems
must be designed to prevent oxygen from entering the
system, this is particularly important to consider when
selecting flex hose, pipes and expansion vessels.
When the system is filled with fresh water, it has an
oxygen content of approximately 8mg/l, however, this
oxygen is consumed quickly through corrosion processes
and within a few days the oxygen in the water should be
consumed. Nevertheless, it is important to avoid filling the
system with fresh water unnecessarily.
Automatic deaerators are often installed to facilitate filling
of the system. It is recommended that the automatic
deaerators are turned off once the system has been fully
vented to avoid these drawing in air in the system if the
pre-pressure in the expansion vessel should drop.
