Uv Start-Up Procedures - GAYLORD XG-BDL Installation Operation & Maintenance

Before using the XG Series Ventilator a complete and thorough start-up of the system must be performed by a qualified, and authorized service
technician. Because of this the UV modules will be shipped separate from the hood to an Certified Service Agent (CSA). Contact Gaylord
Industries to arrange for this service. It is normally included in the purchase price of the hoods.
Start-up requirements and activities
At the time of shipment a Certified Service Agent (CSA)will be
selected to perform the installation of the UV modules and the
start-up for the Ultima Vent system.
The Service agent should confirm the following prior to going to
the job site:
1. The Exhaust and Supply fan(s) are connected to the ductwork
2. The fans have electricity and will run
3. The CUV-100 control panel is mounted and has the following:
• Power to the CUV-100
• All necessary electrical connections between the CUV-100
and the hood, surface fire protection system, and fans.
4. All lighting wiring is connected to the hoods and light switch
5. There is a 120 Volt, 20 Amp power circuit going to each individual
hood section, for UV lamps
6. Any personnel (Fire Marshal, owners rep., GC, FP contractor,
air balancer, etc) required to witness the start up would need
to be notified of time and date for start-up.
Field Start up directions
Allow about 1 hour per hood section, at the job site, for the activities
described below:
1. Check for power to the CUV-100 and wiring between the CUV-
100 and the hoods
2. Check that all XG Extractors are properly installed
3. Start the exhaust fan by turning the CUV-100 control on. Both
supply and exhaust fans should start. The green "UV System
On" light should be on. If this does not occur refer to "UV
Troubleshooting" on pages 14 - 19.
4. Turn CUV-100 control off. This will shut off the fans.
5. Open the UV Access door and remove the blank plate from the
UV light opening.
6. Install the UV light modules in the hood. Connect the plug on the
UV module to the hood, and secure the module in place.
7. Start the exhaust fan and check for the green "UV System On"
light at the hood(s) and control panel. Make sure that all access
doors are closed.
8. Check the plenum pressure at the static pressure tap. See page
12 for details.
9. Record the data on the start up form. Determine the correct
static pressure and record that in the design velocity location.
Then determine the percentage of design that the actual air
static pressure represents
10. Remove an XG Extractor
• The red "Safety Interlock Activated" lamp should come on and
an audible alarm sound.
11. Check the UV Access door interlock
• Open the UV Access door with the fan on.The red "Safety
Interlock Activated" lamp should come on and
an audible alarm will sound.
Caution: Before any Fire tests are performed, check with the
building superintendent to see if the Surface Fire Protection
system is wired to the building alarm, monitoring system, and/
or fire department.

supply Fan(s) shut off, or perform as required.
end user
• If the hood is interlocked with the FP system. Have the
FP contractor test it and confirm that the External fire
mode works properly.
• Instruct them that if for any reason they can see the UV
light directly they must shut off the hood immediately
and call a CSA.
• Check for proper damper operation if this hood has a
GFBD Fire / Balancing Damper. Damper will close once fan
is deactivated.
• How to remove, clean and replace the XG Extractors
• That they need to perform the required end user maintenance
described in the tech manual, hire a CSA to perform the UV
maintenance as described in the tech manual, and have the
duct system inspected/or cleaned as per the requirements
of NFPA-96, or their local authority.
• The frequency will need to be adjusted based on the
type, amount and duration of cooking done at this site.
• Fill out the start up form completely with comments
• Notify the Dealer/customer if the air volumes are more
than 5% low or 15% high and give the dealer and GC
a copy of the Start-up report.
• Send a copy of the Start-up report to Gaylord and keep a
copy for your records.
