“Came with an extra packet of plasticene and an extra drain hose. Also came with a plastic tube for the hole made through the wall. The unit works great. I plugged it into the wall with a 15 amp breaker. Please note not to use a GFCI outlet. This also means any GFCI outlet in tandem to the breaker as that will also trip the gfci further down the wall. This will happen after 5 minutes of it turning on as that’s when the compresser kicks in. I recommend 14 gauge wiring instead of the common 1″.”
“Easy setup working well. Instructions aren’t the best but for $400 I’m happy.”
“We purchased 4 of these units and installed them 6 months ago. They were easy to install. The hardest part was getting the holes through the brick walls of the house. They are quiet and work well. The whole house is now comfortable with no more window units. It is like having central air conditioning at a fraction of the cost!”
