Failure to do so may result in poor performance and wasted time. If any of the above questions cannot be answered accurately, please do NOT proceed with the installation. While any errors made now may be able to be compensated for after the installation is completed, you will incur unnecessary delays and additional costs. Legislation Legislation ii All work that is required regarding the refrigerant circuit must be carried out by an F-gas registered (or equivalent) refrigeration Engineer. On no account should maintenance or repair be carried out on the refrigerant circuit by unqualified personnel. LEGISLATION The installation of the Grant Aerona Heat Pump requires a power supply cable from the customer’s consumer unit to an external isolation switch and from this switch to the heat pump. It will require a final connection to an individual MCB or RHBO within the existing consumer unit or from a newly installed consumer unit. This work MUST be carried out by a qualified electrician or by a Part-P competent installer who has passed an examination proving their competency in these works. Failure to follow this legislation will invalidate all warranties. Please seek advice from a competent person before commencing any electrical work. Information regarding the refrigerant used in this Heat Pump. R407c R407C is a mixture of three refrigerants, each of which boil at different temperatures. R407C has a range or glide of approximately 5.C. The lubricating oils used in this heat pump are known as Polyolester or POE oils. They are considered to be superior oils, less liable to breakdown however they are more hygroscopic – they must therefore be kept from contact with air as far as is practical. Information regarding the charging / recharging of the unit. Always add R407C as a liquid to ensure that the correct mix is added. Charge the heat pump with the correct weight of refrigerant. See data plate for this information. Never ‘top-up’ refrigerant. Always recover the remaining refrigerant first for recycling. Information regarding a refrigerant leak or if the circuit is opened accidentally. Recover the remaining refrigerant as quickly as possible for recycling. Avoid entry of air into the heat pump as much as possible. Replace or install a drier if necessary.

It is important that these installation instructions are understood and followed to ensure reliable operation in all weather conditions. Failure to do so will result in erratic temperature swings, poor efficiency and an unhappy customer. It is not within the scope of this manual to design the heating system or provide any advice regarding the layout of the system or any of the controls required for any individual heating system. These instructions do not replace the installation or users manuals for any additional components used in the design of your system e.g. cylinders, motorised valves, programmers, solar thermal devices, buffers, etc. Grant Engineering UK Ltd offer a design ser...
