� 1.5 PRODUCT HANDLING
° A. Protect ductwork, accessories and purchased products from damage during shipping,
° � storage and handling. The Contractor shall make provisions for the storage of fiberglass
� � and lined sheet metal ductwork in an enclosed trailer, when stored on-site and prior to
�� building "dry-in", to prevent any damage resulting from inclement weather or
� construction traffic. Ductwork shall not be stored outdoors.
,
�� B. Ducfinrork, stored or installed, found to be damaged as a result of moisture, vandalism, �
ti � carelessness or construction traffic shall be replaced in new condition by the Contractor,
;' � � to the satisfaction of the Owner and at no additional expense. There will be no
! � � exceptions.
i
, 1.6 QUALITY ASSURANCE PROCEDURE - DUCT SYSTEMS: The following procedures are
� ,required as a minimum to keep the ductwork clean, as required by the Specifications:
J
'A. Stored ducfinrork should be sealed with Visqueen on each end and all outlets of each
� � piece of duct and covered with Visqueen at all times during storage periods to keep dust
�' from entering the ductwork system.
, ,B. Prior to installation, Contractor shall inspect the ducfinrork and wipe the inside surfaces
, ; of duct clean, if necessary.

� SECTION 15890
ti
�
C. Upon installation of each section of the ducfinrork, all outlets should be covered with
� ! Visqueen and taped shut to keep construction dust from entering the ductwork once it is
installed (if not done in Step #1). This procedure should be carried out the same day
�� ! the ductwork is installed. Duct joints shall be sealed as soon as possible.
' D: Ductwork should be periodically checked by Contractor during course of construction to
„ , insure that protective Visqueen remains sealed around all openings of the ductwork.
�� E. Protective measures should be taken to keep HVAC units from operating during periods
' of high levels of construction dust, such as concrete cutting, drywall sanding, etc.
{ F: HVAC filters should be installed at all air handling units, return air duct openings and
w, j filterback grilles. HVAC Filters should be inspected no less than a monthly basis and
' changed out. During periods of high construction dust, filters are required to be
', i ! changed out as much as once per week, depending.upon visual inspection and the
� ; amount of run time of the unit.
! � I
q G. After completion of installation, the interior walls of ductwork and interior components
� � and walls of air handlers should be inspected for dirt and dust by Contractor, Architect,
Engineer and Owner. If unacceptable amounts of dust and dirt are visible, the unit and
� , ductwork shall be cleaned and tested by Contractor to meet the requirements of the
' � Specifications and NADC 1992-01 "Mechanical Cleaning of Non-Porous Air
" ! Conveyance System components", at no additional cost to the Owner.
� 'H. For-ductwork systems already installed, duct should be cleaned and Visqueen installed
� on all openings (including openings with dampers) to keep future construction dust from
' , entering the system.

,' � � 2. Select a limited section of duct for which the estimated leakage will not exceed the
' capacity of the test apparatus.
" 3. Read the flowmeter and compare the leakage with the allowable rate. If it does not
� meet the allowable rate:
� a. Inspect the pressurized duct for leaks.
� b. Repair all leaks.
� c. Allow repaired seals to cure and retest until the leakage rate is acceptable.
4. Complete test reports.
� � 5. Remove temporary blanks and seals.
� il
, D,. Precautions:
� ; I 1. Isolate equipment (fans, in-line flanged cells, volume regulating boxes, etc.) from
� ; ; tested ductwork.
; i 2. Do not overpressurize ducts.
� � 3. Do not test uncured seals.
� � 4. Conduct required tests before external insulation is applied and before ducts are
� � i concealed by building enclosures.
, 5. Avoid excessive blanking, consistent with industry practice, by testing prior to
� installation of collars for room air terminals.
' E. Apparatus: Refer to the SMACNA Test Manual for type and use of recommended test
apparatus.

B. Start-up Sequence shall be as follows:
�� 1. Air handling units, DX units shall be started with proper filtration and servicing as
li � indicated in these Specifications. Outside air intakes shall be closed.
�� , � 2. Verify proper dehumidification operation of the units such as condensate flow and
�� ,
' � ; DX coil temperature. Ensure chilled water temperature and flow are current for

� ' adjustment of latching devices, installation of end spacers in filter boxes, and
� � proper latching and sealing of access doors. For roll filters, check installation
i i of inedia in curtain guides and over tensioning devices for interlocking of
, controls with fan operation, and check setting of pressures and time controls.
� c. Lubrication: Provide a lubrication schedule, listing the points to be lubricated
, � for each piece of equipment requiring lubrication. List the product and the
application device to be used and the frequency of lubrication required.
° � Provide initial lubrication of the equipment before start-up, along with flushing ,I
of anti-rust compounds that may have been furnished by the manufacturer. �
� 2. Cleanin the Installation: Thorou hl clean the external ortion of installation, !

either in preparation for finish painting or for final acceptance. This may include '
, any or all of the following:
- ,� i ' a. Removal of temporary coverings installed for protection of the work.
� � ' b. Removal of adhesive stickers, except those that give specific maintenance
I
� � instructions or that are otherwise intended to remain for use.
' c. Removal of tags affixed by cord or wire, except permanent identification tags.
, d. Cleaning painted and inked markings, except equipment identification stencils.
' e. Washing down surfaces that are to receive finish painting, using compounds
intended for that purpose.
' f. Cleaning other surfaces, either those with a factory finish or those that are not
; to receive any other finish, so they will be clean for final acceptance.
� g. Cleaning paint splatters and drips from insulation installation_and finishing.
° � h. Cleaning the inside of control box cabinets to remove dirt and scrap material
� � from connections to the panel, by blowing with compressed air or by vacuum
� cleaning�using brush-tipped and pointed wands.
3. Painting: Touch up factory finishes that have been marred. Scratches and
° ; abrasions can be�prepared by light sanding or by removing rust with chemical_
� compounds, such as naval jelly. They can then be coated with a compatible
� ' primer, followed by a matching top coat. Where major damage has occurred on a
' � finished surface, the entire piece should be refinished or replaced. Paint black
� , steel and iron that is exposed to view, using a primer and top coat system,
, following the manufacturer's instructions for surface preparation and application of
the paints.
; 4. Identification of Equipment, Piping and Valves: Identification procedures are
covered in Section 15010-"Basic Mechanical Requirements".
� � 5. Fin Straightening: Inspect finned surfaces of heat transfer coils and repair
, , damaged fins. Where plate-type fins are bent, comb out the fins using combs
' j available for each fin spacing. Where helical wound fins are bent, straighten the
'� fins with a blunt blade, such as a putty knife, and inspect for separation of the fin
� from the tube. Heavy fin damage may call for rejection of the coil.
6. Maintenance Manuals: Provide for the preparation of manuals containing
� operational and maintenance data for the systems as specified in Section 15010 -
� "Basic Mechanical Requirements".

� device to be operated. The usual graphic operational data will include simple daily
start/stop instructions and seasonal changeover instructions, piping identification
j legends, valve identification schedules and diagrams, lubrication schedules, and
control diagrams with operating sequences.
� I 9. Water Treatment Program: Provide for a complete chemical water treatment
� � program with preliminary water testing, recommendations for chemical doses and
