Installation, Operation and Care of
HRO & HRW SERIES ROTISSERIE OVENS
SAVE THESE INSTRUCTIONS
GENERAL
The HRO and HRW Series Rotisserie Ovens and Warmers feature stainless steel interior and
exterior for ease of cleaning. Rotating, self-basting spits or flat baking racks and combination
convection and radiant heat provide thorough cooking and even browning yet eliminate hot spots.
The grease drawer has a drain plug for elimination of excess fat and can be completely removed
for cleaning. Oven controls provide “Manual” or “Automatic” (timer controlled) operation where the
END TIME or PROCESS TIME can be preset. Models HRO220P, HRW220P, HRO330P, HRW330P and
HRO550P provide programmable controls. Tempered glass doors, both front and back, and quartz
lighting promote visual appeal and stimulate customer interest. Doors can be rehinged — contact
your local Hobart service office.
HRW Series have a single compartment upper oven and a lower warming cabinet. The warming
cabinet features low velocity, high humidity air circulation which keeps foods moist. The warming
cabinet has three shelves.
Ovens come in two sizes, with or without warming cabinet below.
HRO101 — oven capacity: four spits (16 chickens).
HRO220 — oven capacity: five spits (20 chickens).
HRO330 — large oven capacity: seven spits (35 chickens).

INSTALLATION
Immediately after unpacking the oven, check for possible shipping damage. If the oven is found
to be damaged after unpacking, 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 on the right side panel near the controls.
HRO550 and HRW330 are secured to the skid with four screws which must be removed.
LOCATION
WARNING: THE OVEN SHOULD NOT BE ACCESSIBLE TO THE CUSTOMER. HOT GLASS AND
PARTS CAN CAUSE BURNS.
The oven may be placed where cooking may be observed to enhance customer awareness. The
oven must be installed on a level surface. A minimum clearance of 10" from the rear, 10" from any
glass, and 4" from each side panel must be maintained. The installation location must allow
adequate clearances for servicing and for proper operation of the front and rear doors.

BEFORE FIRST USE
WARNING: UNPLUG BEFORE CLEANING.
Before using the oven for the first time, it must be “burned in” to release any odors that might result
from heating the new surfaces in the oven.
Clean the oven, accessories and warmer (if present), both inside and outside, with warm soapy
water. Rinse thoroughly and wipe dry with a soft clean cloth. Avoid water contact with the quartz
lamps.
Operate the oven at the maximum temperature setting of 450°F for four hours. Smoke with an
unpleasant odor will normally be given off during this burn-in period.
