Question about Heating & Cooling

1 Answer

We want to remove a non-functioning outside compressor of a Mr.Slim split unit system. Accordng to the installation manual it is either the MS12/15E MSH12/15E model. How do you disconnect and cap off the lines? Is there any special equipment, like a vacuum pump, required? What type of caps can we use?

    Hello, I want to clarify: The unit has not been in use for 10 years and the compressor is not working. Is it possible that some refrigerant is still in the unit? Would it be safe to simpy disconnect it? Or would there be a device where one can check if the refrigerant is still in there and if not then simply disconnect it? Would there be a hazard involved by simply disconnecting it? Thanks

Good day, You will need more than a vacuum pump. If you live in the states you will need a refrigerant recovery unit. It recovers refrigerant and stores it in a ODOT tank for disposal. Unless your licensed you have no access to a device such as this. I would suggest you call a licensed refrigeration or AC company to perform the operation. They would be able to cap any connections at the same time.

    Good day,

    As a licensed refrigeration service tech, I am required to explain the EPA'S regulations.

    However, The law does not,as far as I know, apply to individuals when dealing with this issue.

    I have never known an individual getting into a problem doing what you want.

    I don't know whether the lines are to be just cut, or are in fact fittings.

    If fittings, any commercial refrigeration supply house can supply them. (They are not the same size usually as plumbing fittings. If simple copper, just pinch them shut, and use duct tape, or solder them shut.

    I'm assuming you plan no future with this unit.

    Good,

    however, there is the possibility that there is still some pressure in the system. Proceed with caution. Most units have a device similar to a tire stem. You can depress the pin first to check for pressure, otherwise you would need to loosen a line and wear protective gear, including glasses.

Is your outside coil dirty wash it this may help. Sounds like your head pressure is getting to high and the compressor is kicking out on thermal overload.

Split system outside unit won't come on for cooling, only heating


Check your filters, dog hair and lack of maintenance will definitely burden the cooling mode of the Mr Slim units.

No heating from Mr slim


P8 refers to outdoor protection device activation usually caused by low gas charge or blocked condenser coil. any good a/c company can resolve this for you. however please note that if it is gas related a pressure test must be carried out to determine where that potential leak may be and that can be very costly.
