Model: OVH-10-C Safety
Specific Safety Precautions
For your safety, please observe the following precautions when operating or servicing the OVH-10-C
Ventless Hood. Read the following important safety information to avoid personal injury and/or damage to
the equipment or property.
•Always disconnect the source of main power before removing any service panel or cover.
•Failure to ensure that the Power Switch is in the OFF position during servicing or when replacing filters
could result in damage to the equipment, electrical shock or other serious personal injury.
•Failure to comply with these DANGER notices will result in serious injury or even death, equipment or
property damage, and void the warranty.
!DANGER
•DO NO use or store flammable liquids or materials that produce flammable vapors in the vicinity of
this or any other appliance!
•Consult a qualified electrician to ensure that all electrical requirements are met and that the unit is prop-
erly grounded.
•Before installing or servicing this equipment, read the contents of this manual thoroughly.
•Improper installation, adjustments or alterations, or improper service/maintenance could result in seri-
ous injury or even death, damage to equipment or property, and void the warranty.
•Failure to comply with these WARNING notices could result in serious injury or even death, and equip-
ment or property damage.
!WARNING
UV MODEL ONLY
•An internal ultraviolet radiation source is present on these models during operation.
•Keep protective covers and panels in place during normal operation. Replace any removed after servic-
ing.
•An interlock circuit in the hood reduces potential for exposure to excessive ultraviolet radiation. DO
NO attempt to disconnect or bypass this interlock.
•Looking directly at a V light source without proper eye protection can cause serious eye injury.
!WARNING

vii
Model: OVH-10-CSafety
•Maintain a minimum clearance of 18” (457.2mm) between the hood’s exhaust outlet and the ceiling, or
other overhead obstruction.
•Exercise care when lifting or moving the unit. See Section 1-4.4, Hood Weights.
•Exercise care when removing the unit from the shipping skid.
!CAUTION
•DO NO operate the unit unless you fully understand its components and their intended function.
•DO NO bend the collection fins or break the ionizer wires of the Electrostatic Air Cleaner (EAC).
Doing so will prevent it from working properly and cause a shutdown of power to the appliance being
operated under the hood.
• Failure to comply with these CAU ION notices may result in minor to moderate injury, damage
to equipment or property, and void the warranty.
!CAUTION
•The electronic components of the Control Panel are somewhat impact-sensitive. Exercise care when
performing tasks near the unit’s Control Panel to prevent possible unintentional damage.
•After cleaning the EAC, DO NO attempt to dry the EAC cell by installing it in the hood and running the
fan to force air dry, or by running the appliance under the hood to heat dry. This could potentially dam-
age the EAC power system, leading to failure and voiding the warranty. The EAC filter must air dry at
ambient room temperature, preferably overnight.
•When cleaning the Hood, Hood Skirt or Stand ...
•• DO NO steam clean.
•• DO NO spray with water from a hose.
•• DO NO use products containing chlorine.
•• DO NO use abrasive products, steel wool or scouring pads.
•Failure to comply with these CAU ION notices may result in damage to equipment or property, and
void the warranty.

•The approximate sound level of the hood while operating is 65 dB.
NO E:
•Giles’ responsibility for the damage to the unit ends once the freight shipment is loaded onto the carri-
er’s truck. pon delivery, if the palletized unit showed any signs of damage, the entire load, including
the supplied accessories, should have been inspected immediately and any damage to the equipment
should have been promptly reported to the freight company.
•As an aid for electricians and installers, an electrical wiring diagram is provided with the unit. Refer to
the wiring diagram during installation or while servicing.
•Comply with all appropriate state and/or local heath regulations regarding cleaning and sanitation of
foodservice equipment.
•Giles recommends the use of mild, bio-degradable, non-toxic degreasers, such as Clear Magic or
Simple Green, for cleaning parts of the hood where excessive grease film accumulation is present.
•Always ensure the unit is installed and electrically grounded in accordance with local codes, or in the
absence of local codes, in accordance with the National Electrical Code ANSI/NFPA No. 70-1984.
NO E:
•For some installations, it may be necessary to consult a HVAC specialist to con-
firm that proper room air exchange is occurring and that the on-site A/C system is
capable of handling the anticipated heat load.
•Exhaust ventilation is recommended for areas in which recirculating hoods are operated. Giles recom-
mends 50 CFM per linear foot of hood space. his amount could vary based on local codes and
site-specific situations.
