Motto (JA) Series Instruction Manual Installation and Operation Guide Watch video before Installation Welcome to 5 Things to know before installation Thank You for trusting Della as your home comfort solution. We know no better how exicting it must be to have a new and functional AC to make your living space more comfortable. But AC installation, in reality, is far from being simple. Here are a few things you must know before installing the AC whether by yourself or by a professional HVAC technician. This will give you an idea of what to look out for installing an AC so that it can perform at its maximum efficiency and every dollar you invest in it pays off. The installation location is critical Not all places are created equal. Only proper placement of the AC will maximize efficency while balancing the interior aesthetic. As wall requires for the installation, you need to make sure to get the placement and location right the first time. -1P4a- ge 14 Handle the refrigerant pipes perfectly The refrigerant pipe is one of the most important, if not the most important, parts of the mini split AC system. So, be sure to understand what the entire process entails. You might need special-purpose tools to shorten and bend the pipe. Purchaseing lengthening pipes to match your connection might also be necessary. Any flow in the handling of the refrigerant pipes may cause a refrigerant leak or reduced efficiency. The cost to repair or re-install the refrigerant pipe can quickly frustrate and upset any DIYer, especially when trying to save money by not hiring a professional. Additional refrigerant might also be needed if you used lengthening pipes or find any leaks during your install. Further more, it's always a good idea to test for any refrigerant leaks after completing your installation by using soapy spray or professional detector tools. Please contact us if you need extra refrigerant. -2P2a-ge 22 Bundle the line set correctly The line set contains the refrigerant pipes, drain hose, and electrical wires. A good bundling prevent water condensation and protects it from extermal elements, as well as matching the exact distance of the installation. No one wants extra line set dangling around. -1P8a, 3g0e-18, 34 Vacuum pumping the refrigerant circuit Mini-split AC absolutely needs vacuum pumping in order to perform efficently and prevent refrigerant from reacting with air moisture and damaing the internal parts of the machine. With a vacuum pump and a micron gauge, the process does not take very long, but it is important to do it right. -2P6a-ge 30 Safe electrical connection A safe and properly electrical connection is crucial necessity for the installation. The voltage, power breaker protection, cable requirement and wiring must correspond to the specifications of each model. A poor connection can quickly becomes a fire hazard. -1P2a, 2g5e-12, 25 Most of the problems emerge from incorrect or poor installation. Installation performed by professional HVAC technician can greatly reduce the chance of having problems for years to come. On top of that, Della provide extended warranty for professional installation.
