Specific Safety Precautions
For safety, please observe the following precautions when operating or servicing Model PO-VH or OVH-10 Ventless
Recirculating Hoods. Reading and understanding the following important safety information will help avoid personal
injury and/or damage to equipment or property.
DANGER
!
• Always disconnect the source of main hood power before removing any electrical Access Panel or Cover.
• Failure to have the Power switch in the OFF position during servicing or when replacing filters, could result in
equipment damage, electrical shock and/or serious personal injury.
• Failure to comply with these DANGER notices will result in serious injury or possible death, equipment or
property damage, and could void the warranty.
WARNING
!
• DO NOT use or store flammable liquids, or materials which may produce flammable vapors, in the vicinity of this
or any other appliance!
• Consult a qualified electrician to ensure all electrical specifications have been met and the unit is properly
grounded in accordance with applicable codes.
• Before installing or servicing this equipment, read the contents of this manual thoroughly. Secure the hood
mounting instructions, read and fully understand prior to beginning installation.
• Improper installation, adjustment, alteration, service or maintenance could result in serious injury or possible
death, equipment or property damage, and could void the warranty.
• Failure to comply with these WARNING notices could result in serious injury or possible death, and equipment or
property damage.
vi
Model: PO-VH & OVH-10Safety
CAUTION
!
• Maintain a minimum clearance of 12” (304.8mm) between the hood exhaust outlet and ceiling, or any overhead
obstruction. Giles recommends an 18” (457.2mm) clearance for best performance. Some Hood models are
equipped with an Exhaust Air Diverter attached to the exhaust outlet. In that case there is no
requirement with respect to ceiling clearance.
• Exercise care when lifting, handling and removing the unit from the shipping skid. Refer to Section 1.4.4, Hood
Weights
• DO NOT operate the unit unless you fully understand its components and their intended function.
• Handle the Electronic Air Cleaner (EAC) cell carefully. DO NOT bend the collection plates (fins) or break any of
the ionizer wires. Doing so will significantly reduce the performance of the EAC and will eventually cause power
to the appliance beneath the Hood to be shutdown.
•
Failure to comply with these CAUTION notices may result in moderate to minor injury, equipment or
property damage, and could void the warranty.
minimum
CAUTION
• The Control Panel components are impact-sensitive. Exercise care to avoid damage and maintain proper
operation.
• DO NOT attempt to dry the E.A.C. Cell after cleaning by installing it and running the hood or by running the
appliance below the hood to generate heat for drying. This could potentially damage the EAC Power Supply
causing improper operation and voiding the warranty. NEVER PLACE A WET E.A.C. CELL INTO THE HOOD.
• When cleaning the Hood.
•• DO NOT steam clean or use any type pressure washer.
•• DO NOT use products containing chlorine or other caustic chemicals.
•• DO NOT use abrasive products, steel wool or scouring pads.
• Failure to comply with these CAUTION notices may result in equipment or property damage and could void the
warranty.
vii
Model: PO-VH & OVH-10 Safety
NOTE:
• If after unpacking the unit and its accessories, damage is observed, immediately and thoroughly inspect the Hood
and its accessories. Notify the freight company of any damages. Generally, negotiating freight damage claims
shall be the responsibility of the Customer.
• To aid with electrical installation, a wiring diagram has been included with the unit.
• Comply with all appropriate state and/or local heath regulations regarding cleaning and sanitation of any
foodservice equipment.
• To clean difficult surface areas, having excessive build-up of grease residue, Giles recommends using a mild, bio-
degradable, non-toxic degreaser such as Simple Green
• Ensure that the unit is electrically grounded and installed in accordance with local codes, or in the absence of
local code, in accordance with the prevailing National Electrical Code ANSI/NFPA 70.

2. Installation
This section summarizes the procedures necessary to install your new PO-VH or OVH-10. Before installing this
equipment, please thoroughly read the contents of this manual and any accompanying installation instructions.
Following these procedures and instructions will help to ensure a safe and proper installation.
2.1 Location
CAUTION
!
• DO NOT ALTER, ADD ATTACHMENTS OR OTHERWISE MODIFY THIS EQUIPMENT.
NOTE:
• For some installations, consultation with a HVAC contractor may be required to confirm that proper room air
exchange is occurring, and that the heat load capability of current air conditioning systems is sufficient.
• Exhaust ventilation is recommended for areas in which recirculating hoods are being operated. Giles
recommends at least 50 CFM airflow per linear foot of hood space. This amount could vary based on local codes
and site-specific installation requirements.
• The sound level produced by the hood when operating is approximately 65 dB’s.
1. When using the ceiling mount method of installation, ensure that the overhead structure is sufficient to
support the weight load of the Hood.
2. Once final installation and positioning of the unit is complete, there must be no obstruction of the Hood’s
exhaust air outlet. A minimum clearance of 12” (304.8mm)
overhead obstructions, and the exhaust outlet on top of the unit. Giles recommends an 18” (457.2mm)
clearance for best hood performance.
Some Hood models feature an Air Diverter on the exhaust outlet. In that case there is no
requirement with respect to ceiling clearance, as exhaust is diverted to the sides and rear.

2.2 Unpacking
The unit is shipped on a wooden skid, secured by high-tensile plastic strapping, and wrapped in machine-applied
stretch wrap. In some cases a corrugated sleeve or wooden framework may also be used to protect the unit.
Unpack the unit as follows:
1. Position the unit in an area that provides adequate space for unpacking.
2. Remove the plastic stretch wrap, strapping and other packaging materials as necessary.
3. Carefully remove any wooden supports and/or framework that might be attached to the skid.
4. Locate and secure the envelope containing Warranty Card, Operation Manual, Mounting Instructions and any
other hardware provided for installation. In some cases, additional mounting components may be wrapped
separately and packed with the Hood (usually inside the Soak Tank) ... secure any such items and be certain they
are retained for later use.
5. Secure the stainless steel Soak Tank and set aside. Check inside the Tank, as additional components are often
packed inside. There will be no Soak Tank included with the unit if it is a HEPA Filter model Hood.

NOTE:
• PO-VH & OVH-10 Hoods are designed to operate with either 208V or 240V supply power; the table above shows
amp draw for each voltage.
• Breaker sizes shown apply to Hood power only. Power to the served appliance is typically interlocked through
the hood’s circuitry such that the hood and appliance are powered through the same breaker. In such cases,
breaker size shall be determined by the combined electrical load of the hood and appliance.
