Pre-charged line extension
MRCOOL offers extension couplers that allow you to connect precharged linesets together for an extended run. In order to get to 100 ft you would need the 75 ft extension, model number: DIY25-1412 / DIYCOUPLER-1412K75
Can a condensate pump be added to this unit?
Yes, a condensate pump can be added to this unit. A compatible condensate pump for this unit can be found with the accessories for this product, which are located under the , "add to cart" button or you can view the condensate pump by clicking here. In installations that require the drain line to go against gravity or where the drain line lacks a slope, a condensate pump is strongly recommended. The drain hose will exit the indoor unit on the same side as the line set. You access the drain pan through the same entrance as the air filter. However, to access the drain pan, you must first remove the air filter. For more assistance, please give us a call.
Recommended room size?
Without knowing some important information like insulation quality, geographical location, etc it can be difficult to narrow it down to an exact number.
