What style of plug is on the power cord for the 208/230 unit? My receptacle has a ground and two horizontal holes for the plug. Does the unit come wit

since the unit is also a heater unit, does covering it during winter time affect the heating operation?

Asked by: Anonymous
Thank you for your question. There is a lever that you can use to recirculate the air in the room and not from the outside. I have attached the diagram from your Owner's Manual. I hope this helps.

Does the LT103 CER recycle the water so water does not drip from the pan or overflow onto our customers?

I have bought three of these and the sleeves do not have a drain plug. I would appreciate it if you would show me where the factory instructions state the information I need before I install these units. Thank you in advance for your response.
Asked by: Wayne
The unit does have to drain. The Owner’s Manual advises of the installation instructions and can be viewed on our website at To achieve rearward slope for unit draining, remove the backing from the 1113/16" shim strips and attach them. The higher portion of shim is to be placed in front of the rib on the base of wall sleeve. Pictures of correct installation procedures are provided in the manual as well. Design, features and specifications subject to change without notice.
