as to minimise the likelihood of hydraulic shock
damaging the system.
▪ Mount the indoor equipment and pipes securely and
protect them to avoid accidental rupture of equipment
or pipes in case of events such as moving furniture or
reconstruction activities.
CAUTION
Do NOT use potential sources of ignition in searching for
or detection of refrigerant leaks.
NOTICE
▪ Do NOT re-use joints and copper gaskets which have
been used already.
▪ Joints made in the installation between parts of the
refrigerant system shall be accessible for maintenance
purposes.
