Special requirements for R32
Do NOT have refrigerant leakage and open flame.
Be aware that the R32 refrigerant does NOT contain an odour.
WARNING
The appliance shall be stored so as to prevent mechanical damage and in a well-ventilated room without
continuously operating ignition sources (example:open flames,an operating gas appliance) and have a room size
as specified below.
WARNING
Do NOT re-use joints which have been used already.
Joints made in installation between parts of refrigerant system shall be accessible for maintenance purposes.
NOTE
Make sure installation,servicing,maintenance and repair comply with instractions and with applicable legislation
(for example national gas regulation) and are executed only by authorised persons.
WARNING
Pipework should be protected from physical damage.
Installation of pipework shall be kept to a minimum length.
NOTE
If the total refrigerant charge in the system is <1.84 kg (i.e. if the piping length is <20m for 8/10kW), there are no additional
minimum floor area requiements.
If the total refrigerant charge in the system is ≥1.84 kg (i.e. if the piping length is ≥20m for 8/10kW), you need to comply with
additional minimum floor area requirements as describrd in the following flow chart. The flow chart uses the following tables:
“Table 1-Maximum refrigerant charge allowed in a room: indoor unit” on page 5, “Table 2-Minimum floor area: indoor unit” on
page 5 and “Table 3-Minimum venting opening area for natural ventilation: indoor unit” on page 5.
If the piping length is 30m,then the minimum floor area is ≥4.5m

Unit can be installed at room A if:
▪ 2 ventilation openings (permanently open) are provided between room A and B, 1 at the top and 1 at the bottom.
▪ Bottom opening:The bottom opening must meet the minimum area requirements(VA
min
).It must be as close as possible to the floor.If the ventilation
opening starts from the floor, the height must be ≥ 20mm. The bottom of the opening must be situated ≤ 100mm from the floor. At least 50% of the required
opening area must be situated <200 mm from the floor. The entire area of the opening must be situated <300 mm from the floor.
▪ Top opening:The area of the top opening must be larger than or equal to the bottom opening. The bottom of the top opening must be situated at least 1.5
m above the top of the bottom opening.
▪ Ventilation openings to the outside are NOT considered suitable ventilation openings (the user can block them when it is cold).
