CYANIDE ROOM SEQUENCE OF OPERATION

THE CYANIDE ROOM INCLUDES A ROOFTOP DEHUMIDIFICATION UNIT (RTU-1), CONDENSING UNIT (CU-1), AND TWO EXHAUST FANS (EF-1, EF-2) SERVING THE LAB HOOD AND GRINDER/MIXER, RESPECTIVELY.

THESE SYSTEMS ARE DESIGNED TO BY CONSTANT VOLUME WITH NO AIR RECIRCULATION.

RTU-1 AND CU-1 CONTROLS SHALL BE PACKAGED WITH THE UNIT AND INCLUDE A GRAPHICAL

INTERFACE, LOCATED IN THE SPACE, FOR ADJUSTING SETPOINTS, VIEWING ALARMS, AND

SCHEDULING SYSTEM OPERATION.

FAN CONTROL:

THE SUPPLY FAN AND EXHAUST FANS SHALL OPERATE CONTINUOUSLY WHEN ENABLED. THE

EXHAUST FANS (EF-1, EF-2) SHALL BE INTERLOCKED WITH RTU-1 SUCH THAT BOTH EXHAUST FANS AND

RTU-1 SHALL RUN CONTINUOUSLY WHENEVER AN EXHAUST FAN IS ENABLED. EXHAUST FANS SHALL BE

ENABLED WITH A MANUAL SWITCH LOCATED NEAR THE CORRESPONDING HOOD. EXHAUST FANS AND

RTU-1 SHOULD OPERATE CONTINUOUSLY WHEN CYANIDE IS PRESENT IN THE SPACE.

OUTSIDE AIR DAMPER CONTROL:

THE OUTSIDE AIR DAMPER ON RTU-1 SHALL REMAIN 100% OPEN WHEN THE UNIT IS RUNNING AND

CLOSE COMPLETELY WHEN UNIT IS DISABLED.

DISCHARGE AIR CONTROL:

RTU-1 IS DESIGNED TO PROVIDE HEATING, COOLING, AND DEHUMIDIFICATION. WHEN THERE IS NO

CALL FOR HEATING OR COOLING FROM THE SPACE THERMOSTAT, DISCHARGE AIR TEMPERATURE

SHALL FLOAT. UPON A CALL FOR COOLING AT THE SPACE THERMOSTAT, THE DISCHARGE AIR

TEMPERATURE SHALL BE RESET TO MINIMUM. UPON A CALL FOR HEATING, THE DISCHARGE AIR

TEMPERATURE SHALL BE RESET TO MAXIMUM.

WHEN RTU-1 IS ENABLED, TEMPERATURE AND SPACE HUMIDITY SETPOINTS SHALL BE MAINTAINED AT

70F AND 20% RH RESPECTIVELY. SHOULD THE SPACE CONDITIONS RISE ABOVE SETPOINT

(ADJUSTABLE), THE DESSICANT WHEEL SHALL BE ACTIVATED AND MAINTAIN A MAXIMUM SUPPLY AIR

MOISTURE CONTENT OF 15 GRAINS OF MOISTURE PER POUND OF DRY AIR. SUPPLY AIR MOISTURE

CONTENT SHALL BE MODULATED WITH FACE AND BYPASS DAMPERS AROUND THE DESICCANT WHEEL, INTERNAL TO THE UNIT, USING MANUFACTURER'S CONTROL SEQUENCES.

SAFETIES AND ALARMS:

THE DIFFERENTIAL PRESSURE SENSOR ACROSS THE FILTER BANK SHALL SEND AN ALARM TO THE

CONTROL PANEL WHEN THE DIFFERENTIAL PRESSURE EXCEEDS 2 INCHES W.C. (ADJUSTABLE).

IF THE SPACE HUMIDITY SENSOR EXCEEDS 20% RELATIVE HUMIDITY, AN ALARM SHALL BE GENERATED

AT THE UNIT CONTROLLER.

IF THE SUPPLY AIR TEMPERATURE DROPS BELOW 40 DEGREES F, AN ALARM SHALL BE GENERATED AT

THE UNIT CONTROLLER.

MIXING ROOM SEQUENCE OF OPERATION

THE MIXING ROOM INCLUDES A BENCH STYLE HOOD WITH EXHAUST FAN (EF-3) AND A MAKEUP AIR

UNIT (MAU-1). CONTROLS SHALL BE PACKAGED WITH MAU-1 AND INCLUDE A USER INTERFACE FOR

ADJUSTING SETPOINTS, VIEWING ALARMS, AND SCHEDULING SYSTEM OPERATION.

FAN CONTROL:

THE MAKEUP AIR UNIT AND EXHAUST FAN SHALL OPERATE CONTINUOUSLY WHEN ENABLED. THE

EXHAUST FAN SHALL BE INTERLOCKED WITH MAU-1 SUCH THAT MAU-1 IS ENABLED WHEN THE HOOD IS

SWITCHED ON.

OUTSIDE AIR DAMPER CONTROL:

THE OUTSIDE AIR DAMPER ON MAU-1 SHALL REMAIN 100% OPEN WHEN THE UNIT IS RUNNING AND

CLOSE COMPLETELY WHEN UNIT IS DISABLED.

DISCHARGE AIR CONTROL:

MAU-1 IS DESIGNED TO PROVIDE HEATING AND COOLING. THE UNIT SHALL BE CONFIGURED TO

MAINTAIN 70F DISCHARGE AIR TEMPERATURE, BUT SHALL BE EQUIPPED WITH THE OPTIONAL ROOM

OVERRIDE FUNCTION. THE UNIT SHALL STAGE NATURAL GAS HEAT AND EVAPORATIVE COOLING

SECTIONS TO MAINTAIN SETPOINT.

EVAPORATIVE COOLING:

MAU-1 SHALL BE EQUIPPED WITH A DRAIN/FILL VALVE CONTROLLED AT THE UNIT LCD INTERFACE. THE

EVAPORATIVE COOLING SECTION SHOULD BE DRAINED PRIOR TO FREEZING OUTDOOR AIR

TEMPERATURES.

SAFETIES AND ALARMS:

THE DIFFERENTIAL PRESSURE SENSOR ACROSS THE FILTER BANK SHALL SEND AN ALARM TO THE

CONTROL INTERFACE LOCATED IN THE SPACE WHEN THE DIFFERENTIAL PRESSURE EXCEEDS 2

INCHES W.C. (ADJUSTABLE).

IF THE SUPPLY AIR TEMPERATURE DROPS BELOW 40 DEGREES F, AN ALARM SHALL BE GENERATED AT

THE UNIT CONTROLLER.

CARTRIDGE ROOM SEQUENCE OF OPERATION

THE CARTRIDGE ROOM CURRENTLY CONSISTS OF FOUR EXHAUST HOOD SYSTEMS: 2 SNORKEL

HOODS WITH FANS, 1 SLOTTED BENCH HOOD, AND 1 CANOPY HOOD. THE SLOTTED BENCH HOOD WILL

REMAIN, BUT ALL OTHERS WILL BE DEMOLISHED AND REPLACED WITH A SINGLE EXHAUST PLENUM

WITH FOUR SNORKEL HOODS. SNORKEL HOODS ARE INTENDED TO MAINTAIN A CONSTANT FLOW RATE

WHEN EF-4 IS OPERATING.

A SINGLE EXISTING ROOFTOP UNIT (RTU-2) SERVES THIS SPACE. THE CONTRACTOR IS RESPONSIBLE

FOR ALL NECESSARY ADJUSTMENTS TO RE-BALANCE AND INTERLOCK THE NEW EXHAUST FAN (EF-4)

AND EXISTING BENCH HOOD ((E)EF-2) WITH EXISTING ((E)RTU-2) SUCH THAT THE SPACE MAINTAINS

NEGATIVE PRESSURE WHEN EXHAUST HOODS ARE ON AND MAINTAINS SPACE AND DISCHARGE

TEMPERATURES AS ORIGINALLY DESIGNED.

AIRFLOW RATES:

(E)EF-2 (BENCH HOOD) - 1,500 CFM

EF-4 (NEW SNORKEL HOODS) - 3,500 CFM (700 CFM EACH)

(E)RTU-2 - 4,500 CFM

(E)RTU-2 SEQUENCE

(E)RTU-2 OUTDOOR AIR QUANTITIES ARE CONTROLLED BY MOTORIZED RETURN AIR AND MIXED AIR

DAMPERS. WHEN EXHAUST FANS ARE RUNNING, THE RETURN AIR DAMPER SHALL CLOSE AND THE

OUTDOOR AIR DAMPER SHALL OPEN TO PROVIDE 4,500 CFM OUTDOOR AIR. WHEN EXHAUST FANS ARE

OFF, THE OUTDOOR AIR DAMPER SHALL MODULATE TO MINIMUM POSITION, CORRESPONDING TO 250

CFM OUTDOOR AIR, AND THE RETURN AIR DAMPER MODULATE TO MAXIMUM OPEN POSITION.

EXHAUST FAN INTERLOCKS

EF-4 AND (E)EF-6 SHALL BE INTERLOCKED SUCH THAT BOTH FANS RUN SIMULTANEOUSLY WHEN

SWITCHED ON.

NOTES:

1. CONSTRUCT HOOD WITH 18 GAUGE WELDED GALVANNEALED SHEET METAL.

2. PROVIDE BLAST GATE FOR BALANCING AND WALL BRACKETS FOR MOUNTING.
