OUTDOOr UNIT
refrigeration connections
The length of the connecting pipes must be kept to a minimum.
Connecting pipes must be protected from physical damage and
must not be installed in an unventilated space if this space is
smaller than that shown in the Minimum Floor Area table.
The connecting pipes must be installed in a position where they
are unlikely to be exposed to corrosive substances unless they
are constructed of materials that are inherently corrosion-resist-
ant or adequately protected against corrosion. Compliance with national legislation for the gas in use is man-
datory.
The refrigerant fittings must be accessible for maintenance pur-
poses.
A controlled procedure must be followed to minimise the risk of
flammable gases or vapours being present while working.
Work with heat (welding, soldering, etc�) is prohibited�
