Would not recommend doing that, but it will work, if there is an electrical leak in your system you could get yourself in trouble.

Yes, to ensure safe operation it is extremely important that it has a properly grounded electrical source. It also requires proper ventilation. For our installation, we used a grounded circuit in our garage, and ran the venting pipe from the unit, across the garage ceiling, and out to an exterior wall. The system has performed flawlessly. There was an initial issue with getting all the air out of the pipes and adjusting the water pressure right after installation, but the HVAC company that installed it took care of that problem.

Yes, grounding will be necessary. If you have any other questions please do not hesitate to contact us.

No, it has to be plugged in. (110 volt outlet to power the 12 volt onboard batteries)

A grounded outlet is recommended, not necessarily a deicated oultet. I could not use this machine as it did not have 230v

Yes, the unit plugs into a vertical, double receptacle, and it must be a grounded.

Not to my knowledge. This isn't hard wired into the house. It's self contained batteries. The base unit does plug-in but, it too has an internal battery that is supposed to last 8 hours in case of a power outage. We have a marine battery with an adapter to allow us to 'plug-in' as we live in hurricane country. The individual components all are supposed to have a battery life of a year...easily replaced.

No, this cannot be plugged in. It should be installed by a qualified electrician.

I installed this on a motorhome that has a series wired 12v system from 2 6v batteries. If by negative grounded you mean grounding to the negative terminal on the battery, I have had no problems.

Yes, it did have to be wired in but it has a plug that is accessible on the outside.

No, the frame is not grounded. There is a ground lug on the control panel where they suggest you attach a minimum #12 ground wire which in turn should be connected to your home power panel ground rod, a driven ground rod, or to a cold water pipe. Placing it on concrete blocks has no bearing on it's being grounded. I made up a 15' section of #12 insulated ground wire and permanently attached it to the ground lug with a soldered-on eye lug, then twisted and soldered the other end so that I can attach it to an adjacent ground source (with vice grips is handy).

no it is automatically grounded when you plug it into a 3 prong plug providing your house wiring is correct. They last about 3 winters before the insulation part that is in the water breaks down. When that happens it will blow the fuse or circuit breaker.

Im going to assume you are expecting to plug this into the wall. This is a 12v unit meant to go used on a boat. it has 2 power wires coming out of it you need to wire it up yourself.

You should ask an electrician why it needs one, but I know it won't work without it being grounded.

You can. I did, but you then lose the added protection of having the unit grounded. No big deal for me. Mine works great!

Sorry, that one needs to be plugged in. You would need a generator or a converter.

No it has to be hooked to a transformer that is then plugged into a standard outlet.

You don't need to ground it if you are planning on using it indoors. However, it should be grounded if used outside.
