Installation, Operation and Care of
MODEL HR7E ROTARY OVENS
SAVE THIS MANUAL FOR FUTURE REFERENCE
GENERAL
The model HR7E Oven is a seven-spit rotary oven that features a full view tempered glass door and
quartz lighting that promote visual appeal and stimulate customer interest. The solid back model 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 HR7E rotary oven is 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 and appealingly roasted
product with combination convection and radiant heat.

Only one type of accessory is intended to be used in the oven at a time. Do not mix accessory types.
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).

PLACING THE ROTOR IN THE OVEN
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. 1).
STEP 2: Place the rotor shaft onto upper notch of support
bearing on the non-drive side of the oven (Fig. 2).
Fig. 2
STEP 3: Place the drive side of the rotor shaft on the drive arm
support notch (Fig. 3).
Fig. 1
STEP 4: Turn the rotor, lining up the square drive slots on the
rotor end plate with the pins on the drive arm (Fig. 4).
STEP 5: Nudge rotor toward the drive arm. Non-drive end of
rotor shaft falls into the lower portion of support
bearing hub (Fig. 5). Drive end of rotor shaft is
driven into center hole of drive arm.
STEP 6: Rotor is now in normal operating position (Fig. 6).
