You can install the Mitsubishi FDTC35VH into a standard 600mm ceiling grid. The depth of the indoor cassette unit is only 248mm allowing for fitment into most false ceilings. This model is a full heat pump model so can provide full heating and cooling to rooms up to 40 square meters in size. The unit itself also has an internal condensate pump fitted for water removal when the system is in air conditioner mode. This model uses the latest R32 refrigerant.
