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 eciency and every dollar you invest in it pays o.
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 ow in the handling of the
refrigerant pipes may cause a refrigerant leak or reduced eciency. 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 nd 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.

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.
-18, 30-
Mini-split AC absolutely needs vacuum pumping in order to perform ecently 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.
-26-
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 specications of each model. A poor connection can quickly
becomes a re hazard.

refrigerant is suitable for system needing additional refrigerant charge and which will limit the area of the rooms being
served by the system. Similarly, the total amount of refrigerant in the system shall be less than or equal to the allowable
maximum refrigerant charge. The allowable maximum refrigerant charge depends on the area of the rooms being
served by the system.
• For R454B refrigerant, the maximum charge in a room shall be in accordance with the following:
• Maximum Charge (kg)
• Minimum Room Area (m2)
• M = Mass
• Mmax = Maximum charge mass
• Mc = Mass charged
• A = Floor area
• LFL = Lower Flammable Limit, for R454B LFL is 0.296 kg / m3
• or the minimum oor area Amin to install an appliance with refrigerange Mc (kg) shall be in accordance with:
• Mmax = SF x LFL x h0 x A
• Amin = Mc / (SF x LFL x h0)
