8.4 Splitting 2P Wombat Heaters
The Classic 2P Wombat model heaters can be split in half to allow for ease of installation. To split the heater, follow
these simple instructions:
• Remove the main fan motor loom access plate located on top of the fan cabinet compartment by removing the
single screw.
• Unplug the main fan loom at the connection located inside the access hole which has just been uncovered.
• Remove the 2 screws on each side of the heater fastening the fan cabinet to the heat exchanger cabinet.
• The heater can now be split in two.
• Protect the exposed looms from damage while the heater is split in two parts.
• Once ready, reassemble in reverse order.
Note:
Ensure when reassembling the heater that everything is put back and connected correctly.
