Celiera Ductless Mini Split Air Conditioning Systems are a powerful & flexible way to efficiently cool & heat a room. Each system has two parts : an indoor unit & an outdoor unit. The indoor unit is mounted using a bracket - like a picture frame - on an exterior facing wall, then connected to the outdoor unit using a small hole drilled through the wall. Electricity is supplied via a 20 Amp Breaker (not supplied) to the Outdoor unit. The indoor unit draws its power from the outdoor unit. All Celiera units use the QUICK-INSTALL system, making installation easy. The QUICK-INSTALL system features pre-wired indoor & outdoor units, Quick-Connection terminals for connecting the two units & pre-flared/pre-flanged insulated line sets (connecting pipes). There is no welding or soldering needed and no need to charge the system, since the system comes pre-charged with premium R410 refrigerant. Complete installation kit & hardware is included, plus a manual & installation instructions. Using the QUICK-INSTALL system, setup time is cut in half.
