2 Introduction The purpose of this installation manual is to instruct competent persons how to safely and efficiently install and commission the cylinder system. The target readers of this manual are competent plumbers and/or refrigeration engineers who have attended and passed the requisite Mitsubishi Electric product training and have appropriate qualifications for installation of an unvented hot water cylinder specific to their country.
PAGE 5
2 Introduction Overview of the Controls Built into the front of the indoor unit is the Flow Temperature Controller3 (FTC3). This device controls the function of both the outdoor heat pump unit and the indoor unit. The advanced technology means that by using an FTC3 controlled heat pump you can not only make savings compared to traditional fossil fuel type heating systems but also compared to many other heat pumps on the market.

4 Installation 4.5 Refrigerant Pipe work (Split Model Systems only) 0.5 A ø9.52 For devices that use R410A refrigerant • Use ester oil, ether oil or alkylbenzene oil (small amount) as the refrigeration oil applied to the flared sections. • Use C1220 copper phosphorus for copper and copper alloy seamless pipes, to connect the refrigerant pipes. Use refrigerant pipes with the thicknesses specified in the table below.
PAGE 16
4 Installation 4.6 Electrical Connection The cylinder unit can be powered in two ways. 1. Power cable is run from the outdoor unit to the cylinder unit. 2. Cylinder unit has independent power source All electrical work should be carried out by a suitably qualified technician. Failure to comply with this could lead to electrocution, fire, and death. It will also invalidate product warranty. All wiring should be according to national wiring regulations.
