To Next PageTo Next PageWhat to do if temporary installation and removal of the Toshiba Air to Water Heat Pump are repeated?
If you repeatedly install and remove your Toshiba Air to Water Heat Pump, such as when leased, always use new pipes for the refrigerant piping work.
What to do if the Toshiba Air to Water Heat Pump uses a different type of refrigerator oil?
If the existing Toshiba Air to Water Heat Pump uses refrigerator oil other than Mineral oil, Suniso, Freol-S, MS (Synthetic oil), alkyl benzene (HAB, Barrel-freeze), ester series, or PVE only of ether series, make sure to use new pipes for the refrigerant piping works.
Why refrigerant cannot be recovered from Toshiba Heat Pump?
If refrigerant cannot be recovered using a commercially available dryer attached to the existing pipes, it is possible that a large quantity of dirty oil or moisture remains inside the pipes.
What to do if I see residue or metal dust in my Toshiba HWT-801HRW-E Heat Pump?
If you observe discolored oil, a large quantity of residue, shiny metal dust, or other wear residue or mixture of foreign matter, the existing pipes should not be reused as they are.
What to do if there is a heavy scratch or dent on my Toshiba HWT-801HRW-E pipe?
If there is a heavy scratch or dent on the pipe, be sure to use new pipes for the refrigerant piping works.
What to do if existing pipe thickness is thinner than specified for my Toshiba HWT-801HRW-E Heat Pump?
If the existing pipe thickness is thinner than the specified 'Pipe diameter and thickness,' be sure to use new pipes for the refrigerant piping works.
