Can I mount this to exhaust into my workshop? How many cubic feet of space is required for the unit to operate?

I am mounting this in a wall between my workshop and an office area i am building. My workshop is approximately 2500 square feet and is ventilated with louvers on 2 ends of the shop. is there a formula i can use to determine how big a unit i can install?
Asked by: Denton
It is always recommended to have a window air conditioner vented directly outdoors, as the exhaust is hot, moist air which could make the occupation of such a workshop hazardous.

heater functioning

Does the heater turn on and off by the thermostat? When I activated the heater, the unit continued to operate for over 8 hours with no heat coming out --- it actually cooled the room down instead of heating it up!
Asked by: MoodyElric
It should NOT blow cold air all the time. If you turn the thermostat up to it's highest temp the unit should blow hot until the temp in the surrounding area is reached or the heat pump needs to recycle and then it will blow cool air for a short period and then go back to heating I found that running it in E-Saver while heating was not a good thing as when the heating portion stopped it just blew cold air and did not shut down as I though it would. The instruction book is quite detailed and warrants careful reading...I had to read through it twice.

How long should the compresser stay on?

My husband and I just installed this unit (he is a handyman). It blows fine but the compressor only stays on for about 30 seconds and turns of, then after about 1 minute it comes back on for another 30 seconds. Is this whats its supposed to do? All of out other units do not do this.
Asked by: Casey205
It depends on your settings but based on what your saying I would say that the unit needs Freon or Oil and thus the compressor is cycling on and off. It needs to be checked out or returned to the store! It's definitely NOT normal operation.

Is an outside cover available for this model?

LW1214HR LG - the size of covers I have found online do not fit the dimensions of this model. Any ideas on where to find an outside cover to fit the dimensions for this model?
Asked by: tinker8629
Are you looking for a cover to protect the unit when you're not using it? It comes with a case/cover that it slides into when you mount it. If I were going to cover it for preservation I would get some 2 mil plastic and duct tape it around the unit and seal it up.
