Spe ifi Safety Pre autions
For your safety, please observe the following precautions when operating or servicing your Ventless Hood
equipment. ead the following important safety information to avoid personal injury and/or damage to the
equipment or property.
•Always disconnect the source of the main power before removing the service entrance box cover.
•Failure to ensure the Power switch is in the “OFF” position during servicing and when replacing filters
could result in equipment damage, electrical shock and/or personal injury.
•Failure to comply with these DANGER notices will result in death or serious injury, equipment/property
damage, and void the warranty.
!DANGER
•DO NOT use or store flammable liquids or materials that produce flammable vapors in the vicinity of
this or any other appliance!

!WARNING

vii
Model: FSH-3.5 &FSH-4Safety
•Maintain a minimum clearance of 14” (355.6mm) between the hood outlet and the ceiling or any
obstruction above the hood. 18” (457.2mm) is re ommended for best performan e.
•Exercise care when lifting or moving the unit. See Section 1-4.4 for Hood weights.
•Exercise care when removing the wooden crate from around the unit.
!CAUTION
•DO NOT operate the unit unless you fully understand the components and their intended function.
•Be careful not to bend the fins or break the ionizer wires on the Electrostatic Air Cleaner (EAC). Doing
so will prevent the EAC from working properly and cause a shutdown of power to the appliance being
used with the hood.
• Failure to comply with these CAUTION notices may result in minor or moderate injury, equip-
ment/property damage, and void the warranty.
!CAUTION
•The electronic components of the Control Panel are impact-sensitive. Exercise care around the Control
Panel to maintain proper operation.
•Do not attempt to dry the EAC after cleaning by installing it and running the hood to force air dry or by
running an appliance below to heat dry. This could potentially damage the EAC system leading to fail-
ure and voiding the warranty. The filter must air dry at ambient room temperature, preferably overnight.
•During cleaning of Hood.
•• DO NOT steam clean.

equipment.
•For cleaning areas with excessive particulate build up, a mild bio-degradable non-toxic degreaser (such
as Clear Magic or Simple Green) may be used.
•Always ensure the unit is electrically grounded and installed in accordance with local codes, or in the
absence of local codes, in accordance with the National Electrical Code ANSI/NFPA No. 70-1984.
NOTE:
•A HVAC spe ialist may be required for installations to onfirm proper air
ex hange and the heat load apabilities of the on-site AC system.
•Exhaust ventilation is recommended for areas in which recirculating hoods are used. We recommend
50 CFM per lineal ft. of hood.
•This amount could vary based on local codes and the site specific installation requirements.
