REFRIGERANT PIPING CONNECTIONS Prefabricated refrigerant piping is available as an accessory. If this is used, piping and insulating materials employed must be compatible with this type of installation. The pre-charged outdoor unit does not require charging if piping length is 5 m or less. However, the interconnecting piping and the indoor unit must be pumped down before releasing R22/R407C refrigerant into them from the outdoor unit. 1 - Remove the cap from the service valve.
