UV START-UP PROCEDURES

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.

12.  If the FP contractor is there have them trip the micro switches 

on the FP system to verify that the Exhaust Fan(s) starts and 

supply Fan(s) shut off, or perform as required.

13.  Once all is working correctly demonstrate the following to the 

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.

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.
