WARNING
▪ CVXM-A and FVXM-A Floor Standing range is allowed
to be combined ONLY with systems with total
refrigerant amount
≤1.842 kg . Therefore in case of
combination with outdoor units 3MXM40 or 3MXM52,
the total liquid refrigerant piping length of the
installation MUST be ≤30 m.
▪ For CVXM-A9 and FVXM-A9 refer to "To determine the
minimum floor area" [
4
5].
▪ Spacing. Mind the following requirements:

▪ Do not install the unit more than 60 mm above the floor.
▪ Wall insulation . When conditions in the wall exceed 30°C and a
relative humidity of 80%, or when fresh air is inducted into the
wall, then additional insulation is required (minimum 10 mm
thickness, polyethylene foam).
▪ Wall or floor strength. Check whether the wall or the floor is
strong enough to support the weight of the unit. If there is a risk,
reinforce the wall or the floor before installing the unit.
To determine the minimum floor area
▪ The system using R32 refrigerant is restricted with respect to the
total refrigerant charge and/or the floor area that is served.
▪ To determine the total refrigerant charge ( m ) in the system see
the Installation manual of the outdoor unit.
Note: It is not allowed to install an indoor unit in a room with area
<A
min
(m²).
▪ Depending on the total refrigerant charge ( m ), the minimum floor
area is ( A
min
).
INFORMATION
▪ Use following table and graph for CVXM-A9 and
FVXM-A9.
▪ If the required exact value for the total refrigerant
charge in the system ( m ) is not listed below, use the
closest higher value.
The total refrigerant charge ( m ), the minimum floor area is ( A
min
)
limitation depends also on room height ( H ) and if the unit is installed
ABOVE or UNDER ground level.
