R ECEIVING & INSTALLATION
RECEIVING
Most ClearAir
™
units are shipped in one piece. However, some
units, because of size or special jobsite conditions, may be
shipped in multiple sections. Follow the instructions that are
provided with the unit to join sections back together. If the unit
includes media bed odor control, the KOR48/carbon odor
control media is packaged separately. Verify against the
shipping documents that you have received all items and note
any shipping damage, obvious or hidden, to your carrier and
on your Bill of Lading. If damage is found, immediately file a
claim with the transport company. All units are thoroughly
inspected and fully operation tested at the factory prior to
shipment.
Verify that the electrical and air flow ratings on the unit name
plate agrees with jobsite requirements. If a contradiction arises
notify the factory prior to proceeding with installation.
SAFETY CONSIDERATIONS
Installing and servicing the ClearAir
™
unit can be hazardous
due to the presence of electrical components. Only trained
and qualified service personnel should install or service this
equipment.
Untrained personnel can perform basic maintenance, such
as cleaning and replacing filters. All other operations should
be performed by trained service personnel. When installing or
servicing, observe precautions in literature and on tags and
labels attached to unit.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for brazing operations. Have fire
extinguisher available. Read these instructions thoroughly.
WARNING
Before installing or servicing system, always turn off main
power, exhaust and supply fans to system. There may be
more than one disconnect switch.
Electrical shock can cause
personal injury or death
.
RIGGING
All units are provided with a minimum of four (4) lifting points,
or (2) continuous mounting flanges for rigging attachment.
WARNING: Use all lifting points provided (Refer to Page 10).
Spreader bars are mandatory to prevent contact and damage
to the unit by lifting hooks, straps, cables, or chains. Consult the
mechanical or structural engineer before moving the unit
across the roof deck. Hanging weight is 375 lbs. for the 1x1
and 540 lbs. for the 2x1.
INSTALLATION CODES
This unit requires external plumbing and electrical connections
to be made in the field. It is recommended that the Authority
Having Jurisdiction (AHJ) be consulted regarding local codes
and installation procedures. Gaylord Industries is not
responsible for obtaining necessary approvals and permits
which may be required for installation, nor is it responsible for
verifying that the unit has been installed in accordance with
national, state, and local codes. In the absence of locally
adopted codes use the latest editions of the national electrical
code and the uniform/International mechanical code.
Connections of the exhaust duct to the inlet and outlet of the
ClearAir
™
unit must be fully welded to comply with NFPA-96.
INSTALLATION PRECAUTIONS
1. The services of qualified contractors are essential for safe
and proper installation of this equipment.
2. The air volumes and external static pressures that are
listed on the unit are for the middle of the operating range of
the filters. The initial air volume should be at least 10% higher
than the listed CFM. As the filters load up the air volume will
drop. This is inherent to this type of unit. If the unit is set up
at or below the design CFM, as the filters load up, the kitchen
hood may experience smoke loss problems. Please consult
the factory if you have questions.
3. The unit is designed for installation on a level surface.
4. When installed in an enclosed space a fire-rated
enclosure may be required for the unit and associated duct
work. Consult the Authority Having Jurisdiction.
5. Consult the Authority Having Jurisdiction (AHJ) regarding
requirements covering the point of termination of the exhaust
outlet of this unit. Minimum distances must usually be
maintained between the exhaust outlet and any outside air
intakes and/or adjacent structures or property lines.
6. Do not apply power to the unit until all electrical
connections have been made and a pre-start-up
preliminary inspection has been completed.
7. Allow a minimum of 36 inches clearance in front of the
filter access door and electrical compartment door for ser-
vice and routine maintenance.
SHORT TERM STORAGE
Units that include media bed odor control are provided with
KOR48/carbon media which is shipped separate from the
unit. KOR48/carbon media must be stored in a dry place with
less than 95% relative humidity.
LONG TERM STORAGE (OVER ONE MONTH)
Units must be covered and stored in a warm dry location to
prevent excess moisture from accumulating in the odor media
and final filters.
