Cabin Heater Assembly
This section covers then installation of the cabin heater, which consists of an electrically powered fan and a small radiator.
The base plate can be installed by loosening the screws on the heater unit, to create a wide enough gap to install the base plate.
The base plate can be placed in the same orientation as shown below.
The screws on the heater unit can then be re-fastened, once the base plate installed in the correct position.
I per-treated all of the mounting brackets using established cleaning de-burring and finished using Bonderit.
Mounting brackets are installed without issue, being careful to not over tighten the screws in the plastic.
Hose assemblies are cut to length and temporarily installed.
I opted to go with spring hose clamps instead of the supplied worm-gear drive clamps and the hose coupler is on the engine side of the firewall as shown below. This was done to avoid draining coolant in the cabin during hose replacement.
I added a piece of a fuel line as a way to stabilize the coolant hoses from harmonic vibration that could damage the radiator hose fittings.
This is something I picked up from the Torrence Build Center and is a simple solution that is commonly used on the engine side of the firewall.
Tip #1
These rubber hoses will require replacement at the 5 year mark and Aerospace Innovations has developed a custom silicon (lifetime hose) that does not require replacement. This area is quite difficult to service after the fiberglass windscreen cover has been installed. Aerospace Silicone Hoses
