Installation, Operation and Care of
MODEL HR5E & HR7E ROTARY OVENS
SAVE THIS MANUAL FOR FUTURE REFERENCE
GENERAL
The HR5E and HR7E Ovens are five-spit and seven-spit rotary ovens that feature a full view tempered
glass door and quartz lighting that promote visual appeal and stimulate customer interest. The solid
back model (HR7E only) is used when the oven is positioned against a wall. The glass back model
provides an identical rear glass for customer viewing; with the handle kit accessory the rear glass can
be used for pass-through operation. The HR5E and HR7E rotary ovens are available with stainless
steel or nonstick coated interior for ease of cleaning. The oven’s grease drawer has a drain valve for
elimination of excess fat; the grease drawer can be completely removed for cleaning. The oven
provides evenly cooked, appealingly roasted product with combination convection and radiant heat.

INSTALLATION
Immediately after unpacking the oven, check for possible shipping damage. If the oven is found to be
damaged, save the packaging material and contact the carrier within 15 days of delivery.
Prior to installation, test the electrical service to assure that it agrees with the specifications on the
machine data plate located behind the left-hand hinged door.
LOCATION
The oven must be installed on a level surface. The installation location must allow adequate
clearances for servicing and for proper operation). Minimum clearance for sides and back is 0.0"
(
0.0 cm). The rotary oven is not recommended for installation in high-moisture environments such as
meat rooms or where high pressure cleaning is used.
LEGS / CASTERS / STAND
Each oven is furnished on 1
11
⁄16" (4.3 cm) legs. Casters are included with the stacking kit accessory. An
oven stand is available (HR7E only); the oven is mounted on top of the stand. Tethering is required
for units on a stand or stacked when equipped with casters. Refer to the Stand or Stacking Kit
Instructions.
ELECTRICAL CONNECTIONS
WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE
APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND / OR OTHER LOCAL
ELECTRICAL CODES.
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY TO THE MACHINE AND FOLLOW
LOCKOUT / TAGOUT PROCEDURES.
Single Oven
Access the electrical connection point by removing the side panel where the controls are located. Make
sure that the electrical power supply agrees with the specifications on the oven data plate and complies
with the wiring diagram located on the inside of the side panel.
Stacked Ovens
Refer to the Stacking Kit Installation Instruction included with the stacking kit.
Attach the power supply conduit to bottom of oven. Connect the power supply to the terminal block
as shown on the wiring diagram. Inspect and check all wiring and terminal connections for tightness
and proper routing away from any moving parts or pinch points. Carefully replace side panels.

BEFORE FIRST USE
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY TO THE MACHINE AND FOLLOW
LOCKOUT / TAGOUT PROCEDURES BEFORE CLEANING OR SERVICING.
Oven must be burned in to release any odors that might result from heating the new oven surfaces.
1. Clean oven and accessories, both inside and outside. Refer to CLEANING, pages 25 — 39, for
further instructions.
2. Operate oven at maximum temperature setting of 482°F (
250°C) for 45 minutes. Smoke with an
unpleasant odor will normally be given off during this burn-in period.
PLACING THE ROTOR IN THE OVEN (HR5E)
The rotor must properly engage with the drive mechanism. Orient the rotor so that the end plate with
the drive pin is aligned with the slotted drive hub.
ROTOR
STEP 1: Place the drive end of the rotor shaft into
the slotted drive hub (Fig. 1).
STEP 2: Place the rotor shaft on the support
bearing on the non-drive side of the oven
(Fig. 2).

PLACING THE ROTOR IN THE OVEN (HR7E)
The rotor must properly engage with the drive mechanism. Orient the rotor so that
the end plate with square drive slots is on the same side of the oven as the drive arm.
STEP 1: Stop the drive arm so it is in the down position (Fig. 3).
STEP 2: Place the rotor shaft onto upper notch of support
bearing on the non-drive side of the oven (Fig. 4).
Fig. 4
STEP 3: Place the drive side of the rotor shaft on the drive arm
support notch (Fig. 5).
Fig. 3
STEP 4: Turn the rotor, lining up the square drive slots on the
rotor end plate with the pins on the drive arm (Fig.6).
STEP 5: Nudge rotor toward the drive arm. Non-drive end of
rotor shaft falls into the lower portion of support
bearing hub (Fig. 7). Drive end of rotor shaft is
driven into center hole of drive arm.
STEP 6: Rotor is now in normal operating position (Fig. 8).
