TurboChef HhB Comparison Outline

HhB/HhB 2 Comparison Outline
Cosmetic Differences
The HhB 2 has redesigned skins, an ergonomically-designed
door handle, and a new keypad that includes number keys for
programming. See Figure 1, adjacent. The outer dimensions of
the HhB 2 are also slightly larger:
ORIGINAL H h B
Height 16.5'' (419 mm)
with legs 20.5'' (521 mm)
Width 25.5'' (648 mm)
Depth 29.0'' (737 mm)
with handle 31.5'' (800 mm)
Cleaning Procedure Differences
Detailed cleaning instructions are provided with each oven, as
well as within the owner's and service manuals. The information
below covers only the design differences that affect cleaning.
Single Filter
The original HhB incorporated two filters that were attached
to the back oven cavity wall via clips on hinges. The HhB 2
contains only one filter, which is easier to remove due to a
pivoting filter bracket. See Figures 2 and 3, adjacent.
No Drain System
The original HhB oven incorporated a lidded drain to help
filter debris into the drain pan beneath the cavity during deep
cleaning. The HhB 2 has a water-tight cavity and no drain pan
to better accommodate stacking.
Easier Top Jetplate Removal
For deep cleaning, removing the top jetplate is easier on the
HhB 2 than the original HhB. This is due to additional
clearance to the rear cavity wall.
No Door Removal for Deep Clean
The original HhB oven door could be removed for deep
cleaning. The HhB 2 door should not be removed unless by
authorized service personnel, and can be sufficiently cleaned
while it is attached to the frame.
Easier Cooling Fan Cover Removal
Deep cleaning requires removing debris from the rear cooling
fans. On the original HhB oven, the outlet cooling fan cover
was secured to the back panel via sheet metal screws. On the
HhB 2 oven, the cooling fan cover can be removed without a
screwdriver (Figure 4) for easier and more effective cleaning.
