NOTICE
▪
Take precautions to avoid excessive vibration or pulsation to refrigeration piping.
▪
Protect the protection devices, piping and fittings as much as possible against
adverse environmental effects.
▪
Provide space for expansion and contraction of long runs of piping.
▪
Design and install piping in refrigerating systems such 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.
NOTICE
▪
Do NOT re-use joints and copper gaskets which have been used already.
▪
Joints made in installation between parts of refrigerant system shall be accessible
for maintenance purposes.
Installation space requirements
WARNING
If appliances contain R32 refrigerant, the floor area of the room in which the
appliances are installed, operated and stored MUST be larger than the minimum
floor area defined in table below A (m
2
). This applies to:
▪
Indoor units without a refrigerant leakage sensor; in case of indoor units with
refrigerant leakage sensor, consult the installation manual
▪
Outdoor units installed or stored indoors (e.g. winter garden, garage, machinery
room)
NOTICE
▪
Protect pipework from physical damage.
▪
Keep the pipework installation to a minimum.
To determine the minimum floor area
1 Determine the total refrigerant charge in the system (= factory refrigerant
charge + additional refrigerant amount charged).

2 Determine which graph or table to use.
▪ For indoor units: Is the unit ceiling-mounted, wall-mounted or floor-
standing?
▪ For outdoor units installed or stored indoors, this depends on the installation
height:
If the installation height is… Then use the graph or table for…
<1.8 m Floor-standing units
1.8≤x<2.2 m Wall-mounted units
≥2.2 m Ceiling-mounted units
