A typical new “Back to Back” installation is where the indoor unit is installed on the inside of an external wall, and the outdoor unit is located directly below the indoor unit, mounted on a suitable pad. The pipework and wall penetration is concealed within a Colorbond, sheet metal pipe cover. The condensate drain from the indoor unit is ran in a PVC conduit near the outdoor unit. The power supply is an essential component for the installation of your new system and is a very important task, therefore we only utilise qualified electricians to perform our electrical works.
