General information for the installer
7
Current regulations require the heating installation to
be inspected before it is commissioned. The inspec-
tion must be carried out by a suitably qualified person
and should be documented. The above applies to
closed heating systems. If the heat pump is replaced,
the installation must be inspected again.
DC AWA-SS series is placed on a firm base, preferably a
concrete floor or foundation. Install DC AWA-SS series
with its back to an outside wall, ideally in a room where
noise does not matter. If this is not possible, avoid
placing it against a wall behind a bedroom or other
room where noise may be a problem. Any wall that
backs on to a bedroom should be fitted with sound
insulation. Route pipes so they are not fixed to an inter-
nal wall that backs on to a bedroom or living room.
