      The Ramson website says that you do not need to vacuum the linesets, but the instruction do. Do the linesets have to be vacuumed prior to use?

      Answer This Question

      https://www.ramsond.com/r25v50/ .... The website specific states: "4. NO NEED TO VACUUM THE LINES Once the copper line sets have been connected and tightened, simply open the two release valves. There is no need for vacuum pumping the lines."

        Thank you for your interest, we have thoroughly reviewed our website to find where we say (do not need to vacuum) and have not been able to locate. We have 2 reccomendations when it comes to the final steps of installing our units, 1 we recommend to vacuum the system, that way to ensure all air is out of the system and also check for any leaks at the same time by holding a vacuum. 2nd is to purge the system if you do not have means to a vacuum pump, purging instructions are listed on our website under the customer service tab.

              Is this unit able to control two rooms simultaneously requiring two different temperatures?
              ByJul 13, 2021
              1 Answer | 
              Answer This Question

              Yes, you will be able to climate control 2 different rooms at the same time set to different temperatures, though due to fundamental design both units must be running in the same MODE (e.g. both heating OR cooling, not one heat & one cool).

                I have 2areas that are 1000 sf each. i am thinking i need 2 complete sets...1 ouside unit with 2 modules,?

                Answer This Question

                You can go with 1 outdoor unit and 2 indoor units. For 1000 sqft each you would require a 48,000 Btu outdoor with (2) 24,000 Btu indoor units to handle 2000 sqft total. Ramsond

                  (2)

                  Can I choose to cut the copper line sets to the length I need, flare the ends, and connect without having to worry about having too much refrigerant in the system? One of the lines will be approximately 15 ft, and the other less than 10 ft. Also, I preinstalled the wiring in preparation for a mini split - will 12 AWG wire with 20 AMP breaker be sufficient for this unit?
                  ByMay 20, 2021
                  1 Answer | 
                  Answer This Question

                  Thank you for your interest with Ramsond. You can shorten the lines to 10 and 15 feet and the system will still perform properly, and yes you will have to re-flare the cut lines. Wiring with 12 gauge wire and using a 20 amp breaker is proper for this unit. Ramsond

                    Not Really DIY
                    I bought this because HD advertised as DIY. This is a lie. Units have a big sticker that says warranty void if not installed by a licensed technician. Also, Ramsond says on website no need to vacuum lines, but instruction say to vaccum lines.

                      Customer services is horrible
                      Customer service is horrible, they do not return emails or calls. units also do not come with a manual, you can download and print, if you have a printer and a lot of paper and ink. You can also view online if you have internet service where you are installing and a screen big enough to see it. Haven't got to install unit yet because of the above but hopefully it works better than customer service.

                        Worst delivery ever, I placed 2 diferent orders for a ramsond 18000 btu 1.5 ton dual wall mount mini split, not only did they not delivered on the eta but supposedly the order got lost and they had to reorder and I had to wait again. Two different orders at different times same mini split same thing happened both times. Very disappointed.

                        Not DIY.
                        I bought 4 units (2 Mrcool 3 zones and 2 Ramsond 2 zones). The Mrcool was easy to install, no extra tools. Now the headache with Ramsond, it is so complicated. The lines do not come pre-charged and you need to vacuum the lines( so extra cost for vacuum pump) also there is a special adapter for the vacuum pump that it is sold only online. the Flare Connections are so poor quality and I need to redo some connections, because it leaked maybe I will need to add refrigerant on that.

                          Upper level rooms never got cold in summer/warm in the winter. Got this system and the kids actually stay upstays now. Easy hookup, came with everything needed besides for the main power to unit.
