NOTE

All ﬁeld wiring of electrical equipment must be done to meet all NEC and local electrical codes.

The extent of ﬁeld wiring required will depend on the conﬁguration of the UDS. A few options are broken out in the next portion of this manual. Reference the UDS electrical drawings provided with the unit for more speciﬁc wiring details.

Main Incoming Service

UDS appliance power is typically provided from 120/208/3 and/or 460/3 60Hz power from the building directly to the main breaker(s) within the electrical riser from above. Service size should be shown on the UDS drawing.

• 120/208V/3PH to main breaker, neutral lug, and grounding bar

• 460V/3PH to main breaker and grounding bar

Control Power

The UDS needs a power source to operate all control components. This source must come from a separate, non-shunted breaker from the building; the power must remain constant, even during the event of a ﬁre.

Hose Installation Instructions

1. Check sizes and quantity of hose assemblies as shown on the drawing.

2. Make sure all plumbing 1/4 turn ball valves are in the off position. When the handle is in-line with the pipe, the valve is in the “on” position. When the handle is at a right angle to the pipe, it is in the “off” position.

3. Connect all hose assemblies to the appropriate equipment as shown on the drawing. Provide and install necessary plumbing ﬁttings to present a neat appearance and to ensure that the hose assemblies do not touch ﬂoor. To connect hoses to quick disconnects, pull back sleeve, and push plug into socket. To disconnect, pull back sleeve, unlocking the coupling.

4. To ensure proper installation and minimal wear of hoses, follow the examples shown below:

Do not offset couplings. This creates torsional twisting and undue strain causing premature failure.

Allowing a sharp bend strains and twists the metal hose to a point of early failure at the coupling.

Couplings and hose should be installed in the same plane as shown.

This is the correct way to install metal hose for vertical traverse. Note the single natural loop.

Start-Up

Testing

1. After installation has been completed, including plumbing and electrical connections, replace all access panels in the electrical chase.

2. Make sure all breakers (including the main) are in the off position.

3. Make sure all service and appliance ball valves are closed.

4. Slowly open the cold water main supply ball valve (if provided). Check for leaks between the main ball valve and appliance ball valves. Once check is complete, close the main supply valve.

5. Repeat step 4 for hot water and steam valves (if provided), as well as any other plumbing valves except for gas (if provided).

6. Turn on main service circuit breakers.

7. Turn on each branch breaker and check the status lights (if provided) and GFCI receptacles connected to each breaker. Continue with all branch breakers.

8. Slowly open the gas main supply ball valve until fully open (if provided). If equipped with an electric gas valve, press the RESET button on the ﬁre fuel shut off panel to allow gas to ﬂow to the appliance ball valves. Check for leaks.

9. At this point, hook up all equipment (plug and cordsets, plumbing hoses). Refer to Hose Installation Instructions found on this page.

10. Open all appliance ball valves.

11. With everything on, test appliances for proper operation and look for any leaks.

12. If provided, test ﬁre fuel shut-off (see page 10 for ﬁre fuel shut off operation).

Closing in the diameter at the coupling creates double bends causing work fatigue failure of ﬁttings.

Maintain the minimum or larger bending diameter between the couplings for longest life.

Sequence of Operation

GAS "ON"

RESET

E-STOP

ALARM

after the ﬁre system is returned to the cocked (armed) position under normal operating conditions, the button marked gas reset must be pressed to allow gas to ﬂow to all gas operated equipment. A “GAS ON” pilot light will illuminate when gas is allowed to ﬂow to all gas operated equipment.

1. Electricity

Actuation of the ﬁre system will trip all circuit breakers equipped with the ﬁre-fuel shut off feature and deenergize the corresponding outlets. Typically, this occurs only on the main service shunt trip breaker(s) in the UDS electrical riser. If equipped, the audible alarm in the UDS will sound. After the ﬁre system is returned to the cocked (armed) position under normal operating conditions, these circuit breakers will remain de-energized until manually reset.

2. Gas

Actuation of the ﬁre system will stop all gas ﬂow to the gas operated equipment. If equipped, the audible alarm in the UDS will sound. If the UDS is supplied with a mechanical gas valve, after the ﬁre system is returned to the cocked (armed) position under normal operating conditions, gas will ﬂow to all gas operated equipment. If the UDS is supplied with an electric gas valve,

Testing

1. Turn all individual equipment controls to the OFF position before attempting to connect or disconnect any cord and plug assembly. After the cord and plug assembly is connected, equipment may be turned ON.

2. When the circuit breaker is in the OFF position, the receptacle operation indicator light will not be illuminated. To energize the outlet, turn the circuit breaker to the ON position. The receptacle operation indicator light will turn ON.

3. To test the connection plate, turn the circuit breaker to the ON position and press the PUSH TO TEST button. The circuit breaker will automatically turn to the OFF position and the outlet will be de-energized.

4. Turn the circuit breaker back to the ON position and the outlet will be energized. The equipment is now ready for operation.

Current Sensor Adjustment

NOTE

Ground fault nuisance tripping may occur on certain pieces of equipment. If this situation occurs, follow these steps

1. Turn off ALL main services to raceway.

2. Carefully remove the screws securing the access panel.

3. Locate the ground fault sensing relay and adjust the potentiometer slightly clockwise.

4. Carefully replace the access panel and tighten securely.

5. Test the circuit breaker and appliance.

IMPORTANT

After the gas has been reset, all pilot lights must be re-lit. Failing to re-light pilots will cause gas to ﬂow into the kitchen.

Emergency Stop

Depressing the emergency stop switch will trip the main shunt trip breaker(s), and stop all gas ﬂow to the gas operated equipment (if provided with an electric gas valve). To reset, pull this emergency stop switch out, then press the RESET button. The main circuit breaker must then be reset (turned to the OFF, then to the ON position) to re-energize the outlets.

IMPORTANT

After the gas has been reset, all pilot lights must be re-lit. Failing to re-light pilots will cause gas to ﬂow into the kitchen.
