One Eprom for All Electrical Configurations
The HhB 2 epr
om can be used regardless of electrical
configuration, unlike the original HhB oven which had
different eproms for single or multiphase operation.
NOTE: The HhB 2 eprom is not backwards-compatible
with the original HhB.
Rack Motor Location and Installation
The rack motor on the original HhB o
ven was located on the
left side of the o
v
en cavity, and was connected to the swing
arm assembly by a drag link. The rack motor on the HhB 2
o
v
en is located on the right side of the oven cavity and is
connected directly to the swing arm. The elimination of the
drag link impr
oves rack oscillation reliability. See Figures 11
