CHAPTER 1
CONVOTHERM BY CLEVELAND GENERAL INFORMATION

A. GENERAL SAFETY GUIDELINES FOR INSTALLERS, USERS, AND SERVICE

TECHNICIANS

1. Read, understand, and follow the instructions, and heed and obey the warnings of the
Installation Manual and Operators Manual, and the labels on the Combi, accessories, and
supporting products.

2. Improper installation, maintenance, cleaning, or modifications to the Combi can lead to injury
or death of the operator(s), and equipment and property damage.

3. STEAM – To avoid steam burns, open the Combi door by turning the han dle to the horizontal
(“airing”) position and waiting for the steam and condensate to clear. Then stand back and to
the hinge side of the door and slowly open the door. Never breathe steam, superheated
steam, or hot air. Note: The cooking program is interrupted whenever the door is opened.

4. HEAT – The Combi, cooking containers, shelves, and inner door and anythin g else inside the
cooking compartment are HOT, as are many of the component parts. Wear DRY heatproof
gloves or mitts.

5. EXHAUST VENTS – The top of the Combi, and the gas and steam exhaust vents are very
hot during operation and remain hot for some time. Never breathe gas or steam from the
exhaust vents. Use extreme caution when working on or near this area and component parts.

6. SCALDS – Do not place containers with liquid contents or contents that become liquid on
oven racks higher than you can see into the containers. Cover containers (individual or on
trolleys) containing hot or hot liquid items to help prevent spills during transport. Observe and
heed and obey the additional warnings and warning labels posted on the Combi

7. GREASE SPATTER – Hot grease will spatter and cause burns if sprayed with water. Locate
fryers and similar appliances outside the range of the Combi hand shower.

8. ELECTRIC SHOCK – Use the hand shower only on the inside of the oven. Use of the hand
shower, hoses, power cleaners, or pressure washers on the outside of the Combi can cause
electric shock and / or damage electrical and electronic components.

9. CLEANING AND DAILY MAINTENANCE – Wait for the Combi to cool before cleaning and
performing daily maintenance. Do NOT spray water in a hot cooking compartment. Do not
use hoses, power cleaners or pressure washers, or harsh or a brasive cleaning agents inside
OR outside the cooking compartment.

10. CLEANING AGENTS – Use only Convotherm by Cleveland cleaning and descaling products.
Follow the instructions, and heed and obey the warnings on the labels. Other product s ca n
damage the Combi, cause injury, or present heath hazards.

11. Wear BOOTS appropriate to the work area to help protect feet, and to help prevent slips and falls.

12. Use non-slip, draining, anti-fatigue FLOOR MATS (not included) rated for use in wet, greasy,
and dry work areas to help prevent slipping and / or falling injuries. Obtain the best mats for
your needs from your local supplier.
