Hot In the Smoke Room – Cooling Condenser Tripped

If the cooling condenser unit/s trip out, they will have a blinking red status and grey condensing box on screen. This means it is not working and needs to be reset.

MUA-01 Smoke Room Cooling Condenser Location

There are two units that are used for cooling the Smoke Room.

• Condenser East – AHU-01
• Condenser West – AHU-02

These are located on the roof on the South West corner of the Smoke Room addition.

Turn On MUA-01 Smoke Room Cooling Condenser Water

In the event that there are any cooling condensing units tripped out, the “Band-Aid” water fix will need to be applied to ensure they stay on. This happens when it is too hot out and they need to be cooled with water. Not applying water will more then likely result in the unit tripping again until it cools off outside. Pictures are included for each step to complete this process. When in doubt, contact the Asset Protection Manager.

• Ensure both water valves are on near the Roof Hatch.
• Ensure water is on the problem Cooling Condenser from the spray heads on the South side of the unit.
• If water is off, turn the black collar of the spray head to turn on water, make sure the water direction is on the unit.

Reset MUA-01 Smoke Room Cooling Condenser

Once the “Band-Aid” water fix is on, the Cooling Condenser can now be reset. Pictures are included for each step to complete this process. When in doubt, contact the Asset Protection Manager.

*** CAUTION *** When a tripped red pressure switch is reset, it will automatically start with a loud humming sound. Be aware of this while pressing. If this does not happen, contact the Asset Protection Manager.

• Locate tripped Cooling Condenser – See MUA-01 Smoke Room Cooling Condenser Location.
• Go to right side door on North side of the unit, open door.
• Locate red pressure switches.
• Press each pressure switch.
• If none of them reset with a noticeable loud humming sound, try the other unit as you may be at the wrong unit.
• Monitor on the BMS that they all come back on. They are on a time delay and will take roughly 5 minutes each for the next stage to come on, if there are more then one Cooling Condensers tripped. Be patient.
• If none of them reset, and after an allotted time they do not reset or keep tripping out, contact the Asset Protection Manager for further direction.

Main Gaming Floor

There are three units that operate for the Main Gaming Floor. All three need to be looked at to identify if there are issues.

• RTU-04 – Casino Center * This is the main unit that does the brunt of the work.
• RTU-02 – Casino West
• RTU-03 – Casino East

*** If RTU-04 is ever off, it will default RTU-02 and RTU-03 into heating mode, if the unit cannot be turned back on, contact the Asset Protection Manager. See Hot on Main Gaming Floor – RTU-04 Off, RTU-02 and/or RTU-03 Supplying Heat for instructions.

These units do not have status indicating lights for all functions. Be aware of this when looking at the BMS.

Normal Operation – Summer

• All blower motor command lights are green.
• Only RTU-04 blower motors has status indicating light, this should be green.
• Room temperature on RTU-04 is fairly close to set point.

Hot on the Main Gaming Floor – Motors are Off

If any of the motors are not turning and the status is flashing RED, the motor is not on.

• Try resetting the unit.
• Go to the Electrical Room in the North West Basement.
• Locate breaker A-4. Turn off, leave off for one minute, and turn back on.
• Monitor on BMS and ensure unit starts operating properly, this may take a few minutes.
• If unit does not turn back on, contact the Asset Protection Manager for further direction.

There is no good indicating way to know if RTU-02 and RTU-03 motors are off without going to the roof to investigate.

Hot on the Gaming Floor – RTU-04 Cooling Condenser Tripped

If the cooling condenser unit/s trip out, they will not have an indicating light. It can be assumed that if both stages of cooling are being called but the Supply Air is high, that the cooling is not working. The red pressure switches will need to be reset. If the water is off on the Cooling Condenser, it will need to be turned on first to be able to reset the unit. Contact the Asset Protection Manager for further direction.

RTU-02 and RTU-03 do not have status indicating lights and will need to look at the Supply Air to see if it does not seem to be a normal temperature of between 8°C and 15°C. They do not have pressure switches. Contact Asset Protection Manager for further direction.
