(A) Ceiling Cassette-4Way Compact (600 600Mm) Type (Fdtc) - Mitsubishi Heavy Industries FDTC40ZHXV Technical Manual

1.2.6 Selection chart
Correct the cooling and heating capacity in accordance with the operating conditions. The net cooling and heating capacity can be
obtained in the following way.
Net capacity = Capacity shown in the capacity tables (1) × Correction factors shown in the table (2) (3) (4).
Caution: In case that the cooling operation during low outdoor air temperature below -5°C is expected, install the outdoor unit
where it is not influenced by natural wind. Otherwise protection control by low pressure will be activated much more
frequently and it will cause insufficient capacity or breakdown of the compressor in worst case.

Note(1) These data show average statuses.
Depending on the system control, there may be ranges where the operation is not conducted continuously.
(2) Capacities are based on the following conditions.
Corresponding refrigerant piping length :7.5m
Level difference of Zero.
(3) Symbols are as follows.
TC : Total cooling capacity (kW)
SHC : Sensible heat capacity (kW)
HC : Heating capacity (kW)
(4) SHC is based on each DB and
SHC correction for other dry bulb.
