Senville SENL-24CD 24000 BTU 15 SEER Split Air Conditioner and Heat Pump, Mini

We bought Romex underground 12/2 GUFRCR with ground wire for power wire. And The control cable: 14/3 with ground (four total wires) control type cable does the trick. We bought 14/4VNTC tray cable. It should be with stranded wire. Both wiring choice worked great and both were bought at Wholesale Electric Suppy. No issues.

P.S. if by chance you use a GFCI breaker do NOT get one with a ground fault interrupt. The GFCI with fault interrupter kept tripping the breaker. We ended up using a standard 20-amp Square D homeline breaker. Hope this is helpful.

I bought the 24K BTU unit for an 800sq. ft. un-insulated garage. The installation was new so all electricity, holes and mounting had to be done from scratch.I am DIY’er and was comfortable with doing everything excepting the final line vacuum and pressure test mainly becuase it was more expensive to buy the tools for this than to hire someone.

The unit came with most of the materials needed for installation. A word of caution, in order to install the mini split I had to purchase about $200 in tools including:
– Yellow jacket Flare tool 60278 : 410a systems require a very particular flare
– crowfoot wrench set Neiko : Allows you to use a torque wrench to achieve the require torques
– nylog : refrigerant sealant
If you want to vacuum it out yourself you’ll spend another $400 -$600 dollars because you will need a two stage vacuum pump, 410a adapter and a micron meter. I paid a professional $300 for this step.

The unit does come with the outside condenser unit filled with refrigerant, (2)16 foot hoses, inside air handler, remote control, vinyl wrap, neoprene block, drain hose for inside unit and extra pipe connectors. You will need to supply electricity, control wires from the air handler to the compressor, screws for mounting the air handler, outside 230v AC disconnect switch, waterproof electrical wire conduit, and a wall mount or base for the outside compressor. I wound up purchasing some 10-12 AWG spade crimps for the wires. My only complaint regarding the installation was that the electrical terminal for connection the 230v main and control wires was too small and frail. It wouldn’t accept 12AWG wire which is why I would up having to buy the crimps to get the wires to connect to the block.

The unit is able to cool down an un-insulated 800sq. foot area to 75 degrees on a humid 95 degree day. I’ll wait for winter to judge the heat pump portion of the unit but so far I am very satisfied.
