Number] This asymmetric heater enters and exits the
freezer door perimeter insulation void through a 10 mm
[3/8”] copper tubing loop, with ends located behind left
penetration in panel behind front control overlay. (See

freezer bottom perimeter insulation through a similar 10
mm [3/8”] copper tubing loop, with ends located lower-right
