CONSTRUCTION.

E. IN VIEWING THESE DRAWINGS, THE CONTRACTOR SHALL PAY CLOSE

ATTENTION TO THE MATCH LINES. SOME WORK AND NOTE REFERENCES

MAY BE REPEATED, BUT DO NOT ALWAYS SHOW ON BOTH SIDES OF THE

MATCH LINE

F. CONTRACTOR SHALL COORDINATE THE ROUTING OF ALL PIPING WITH

STRUCTURE, CEILING, LIGHTING, AND DUCTWORK.

G. MAINTAIN MANUFACTURER'S REQUIRED CLEARANCE AROUND ALL

EQUIPMENT TO ALLOW FOR MAINTENANCE ACCESS.

H. DO NOT ROUTE DUCTWORK OR PIPING ABOVE ELECTRICAL PANELS.

MAINTAIN ALL CODE REQUIRED CLEARANCES.

J. IN THE EVENT THE CONTRACTOR ENCOUNTERS ON THE SITE, MATERIAL

REASONABLY BELIEVED TO BE ASBESTOS, LEAD-BASED PAINT, OR ANY

OTHER HAZARDOUS MATERIAL WHICH HAS NOT BEEN RENDERED

TO BE REMOVED, RELOCATED, OR SALVAGED ARE SHOWN AS SOLID, FULL-

TONE LINES. ALL OTHER ITEMS ARE INTENDED TO REMAIN IN PLACE AND

ARE SHOWN AS HALF-TONE.

B. DEMOLITION SHALL INCLUDE, BUT IS NOT LIMITED TO, THE ITEMS LISTED

BELOW OR HERE-IN. THE CONTRACTOR SHALL COORDINATE ALL

REQUIRED RENOVATION AND NEW CONSTRUCTION WITH THE EXISTING

BUILDING TO IDENTIFY THE TOTAL EXTENT OF THE DEMOLITION REQUIRED

AND AS LISTED BELOW.

C. THE REMOVAL OF HVAC AND PLUMBING EQUIPMENT FROM FINISHED AREAS

AND THROUGH WEATHER BARRIERS SHALL BE COORDINATED WITH

ARCHITECTURAL PLANS AND DETAILS AS WELL AS NOTES ON THE

MECHANICAL DRAWING TO ENSURE PROPER PATCHING AND REPAIR IS

MADE TO THE BUILDING.

D. THE CONTRACTOR SHALL BE RESPONSIBLE FOR THE DEMOLITION AND

REMOVAL OF ALL EXISTING COMPONENTS, MATERIALS, EQUIPMENT, AND

APPURTENANCES AS REQUIRED TO BUILD, ERECT, INSTALL, OR

1. GENERAL

1.1 UNIT IS NORMALLY STARTED AND STOPPED REMOTELY AT THE ECC. H-O-A SWITCH SHALL BE KEPT IN THE "AUTO" POSITION. "HAND" AND "OFF" POSITIONS SHALL BE USED ONLY FOR MAINTENANCE.

WHEN THE UNIT IS "OFF" D-1, D-3, SHALL BE FULLY CLOSED. WHEN THE UNIT IS "ON" D-1, SD-1 AND

SD-2 SHALL BE FULLY OPEN. D-2 AND D-3 SHALL MODULATE IN ACCORDANCE WITH THE FOLLOWING

SEQUENCE:

7. EMERGENCY CONSTANT SPEED OPERATION

7.1

SUPPLY AIR TEMPERATURE, SENSED BY TT-1, SHALL BE MAINTAINED AT SETPOINT VIA DIGITAL

CONTROL PANEL BY MODULATING V-1 OR D-2 AND D-3 OR V-2 IN SEQUENCE.

WHEN THE TEMPERATURE OF THE OUTSIDE AIR, SENSED BY TT-2, IS ABOVE 75°F (ADJ) [23.8°C], THE DIGITAL CONTROL PANEL SHALL PREVENT THE MODULATION OF D-2 AND D-3 AND SHALL ASSUME THE MINIMUM OUTSIDE AIR POSITION (D-2 FULLY OPENED AND D-3 FULLY CLOSED). THE DIGITAL

CONTROL PANEL SHALL MODULATE V-1 TO MAINTAIN THE SUPPLY AIR TEMPERATURE, SENSED BY

TT-1.

WHEN THE TEMPERATURE OF THE OUTSIDE AIR, SENSED BY TT-2, IS BETWEEN 65°F [18.3°C] AND THE SUPPLY AIR TEMPERATURE SENSED BY TT-1, DAMPER D-2 SHALL FULLY CLOSE AND D1 AND D3 SHALL BE FULLY OPEN (MAXIMUM OUTSIDE AIR POSITION). THE DIGITAL CONTROL PANEL SHALL

MODULATE V-1 TO MAINTAIN THE SUPPLY AIR TEMPERATURE, SENSED BY TT-1.

WHEN THE TEMPERATURE OF THE OUTSIDE AIR, SENSED BY TT-2, IS BELOW THE SUPPLY AIR

TEMPERATURE, SENSED BY TT-1, DAMPERS D1, D-2 AND D-3 SHALL MODULATE TO MAINTAIN THE SCHEDULED SUPPLY AIR TEMPERATURE. IF D-2 IS OPEN AND D-3 IS CLOSED TO MINIMUM OUTSIDE AIR, V-2 SHALL MODULATE OPEN TO MAINTAIN THE SUPPLY AIR TEMPERATURE, SENSED BY TT-1.

THE SUPPLY AIR FLOW SHALL BE CONTROLLED BY THE DIGITAL CONTROL PANEL MODULATING THE

SUPPLY FAN VARIABLE SPEED MOTOR CONTROLLER TO MAINTAIN 1.0" [25mm] OF DUCT STATIC PRESSURE (FIELD ADJUSTABLE), SENSED BY SPS-1. RESET STATIC PRESSURE BASED ON ACTUAL

BUILDING LOAD BY POLLING ALL ATU

THE DIGITAL CONTROL PANEL, USING TOTAL SUPPLY AIR AND RETURN AIR FLOW SIGNALS, SHALL

RESET THE RETURN AIR FAN VSMC TO MAINTAIN A CONSTANT AIR FLOW DIFFERENCE BETWEEN

THE SUPPLY AIR AND THE RETURN AIR EQUAL TO MINIMUM OUTSIDE AIR.

USING HIGH PRESSURE SENSOR SPS-2 LOCATED AT THE SUPPLY FAN DISCHARGE, SHALL PREVENT

THE SUPPLY FAN FROM DEVELOPING OVER 3" [75mm] OF STATIC PRESSURE (FIELD ADJUSTABLE). IF STATIC PRESSURE AT SPS-2 DOES EXCEED 3" [75mm] THE SUPPLY AIR FAN SHALL STOP. SPS-2 SHALL BE HARDWIRED TO THE SUPPLY FAN VSMC AND UNIT SHALL BE SHUTDOWN IN HAND,AUTO

OR BYPASS MODE. SPS-2 WILL REQUIRE MANUAL RESET AT THE DEVICE.

UPON FAILURE OF THE VSMC, THE SUPPLY AND RETURN FANS SHALL BE STARTED/STOPPED

MANUALLY AT THE DIGITAL CONTROL PANEL OR THE ECC THROUGH THE BY-PASS STARTER. FANS

SHALL THEN BE OPERATED AT CONSTANT SPEED.

IF THE AIR TEMPERATURE AS SENSED BY TT-3 FALLS BELOW 45°F [7°C], AN ALARM SIGNAL SHALL INDICATE AT THE DCP AND ECC. IF THIS TEMPERATURE FALLS BELOW 40°F [4.4°C], AS SENSED BY

THE TSL THE SUPPLY AND RETURN FANS SHALL SHUT DOWN AND A CRITICAL ALARM SHALL

INDICATE AT THE DIGITAL CONTROL PANEL AND ECC. TSL SHALL BE HARDWIRED TO THE SUPPLY

FAN UFD AND UNIT SHALL BE SHUTDOWN IN HAND,AUTO OR BYPASS MODE. TSL WILL REQUIRE

MANUAL RESET AT THE DEVICE.

WHEN SMOKE IS DETECTED BY DUCT SMOKE DETECTOR, SD, THE SUPPLY AND RETURN FANS

SHALL SHUT "OFF" AND AN ALARM SIGNAL SHALL BE TRANSMITTED TO THE FIRE ALARM SYSTEM.

ALL SMOKE DAMPERS IN THE SUPPLY AND RETURN DUCTS SHALL CLOSE.

EXHAUST FANS SERVING AREA OF THE SUPPLY FAN SHALL CONTINUE TO RUN. SUPPLY AND

RETURN FANS SHALL RESTART AND SMOKE DAMPERS SHALL OPEN WHEN FIRE ALARM CIRCUIT IS

RESET.

WHEN THE DIGITAL CONTROL PANEL IS NOT CALLING FOR HUMIDITY, SENSED BY RETURN AIR

HUMIDITY H-1, 2-WAY "ON-OFF" CONTROL VALVE V-3 SHALL REMAIN CLOSED. WHEN THE DIGITAL

CONTROL PANEL IS CALLING FOR HUMIDITY, V-3 SHALL REMAIN OPEN.

RETURN AIR HUMIDITY SHALL BE MAINTAINED AT SETPOINT OF 35% RH (ADJ) VIA DIGITAL CONTROL PANEL BY MODULATING CONTROL VALVE V-4 TO MAINTAIN THE DESIRED HUMIDITY. THE DCP SHALL

OVERRIDE THIS CONTROL TO MAINTAIN HUMIDITY OF 80% AS SENSED BY H-2. DCP SHALL CLOSE

VALVE V-3 WHENEVER THE SUPPLY FAN IS OFF. VALVE V-4 SHALL BE INTERLOCKED WITH A

TEMPERATURE SWITCH TO KEEP THE HUMIDIFIER OFF UNTIL CONDENSATE TEMPERATURE

APPROACHES STEAM TEMPERATURE.

SEQUENCE OF OPERATION FOR VARIABLE AIR VOLUME AIR HANDLING UNIT WITH MINIMUM OUTSIDE AIR

8.1

8.2

THE ECONOMIZER SHALL BE ENABLED WHENEVER THE OUTSIDE AIR TEMPERATURE SENSED BY

TT-2 IS LESS THAN 65°F (ADJ.) AND THE OUTSIDE AIR TEMPERATURE SENSED BY TT-2 IS LESS THAN

THE RETURN AIR TEMPERATURE SENSED BY TT-4 AND THE SUPPLY FAN STATUS IS ON. THE

DIGITAL CONTROL PANEL SHALL MODULATE DAMPERS D-1, D-2 AND D-3 TO MAINTAIN A SUPPLY AIR TEMPERATURE SENSED BY TT-5 AT 2°F (ADJ.) LESS THAN THE SUPPLY AIR TEMPERATURE COOLING

SETPOINT.

THE ECONOMIZER SHALL BE DISABLED WHENEVER THE MIXED AIR TEMPERATURE SENSED BY TT-5 IS LESS THAN 50°F (ADJ.) OR THE FREEZESTAT IS ON OR ON LOSS OF SUPPLY FAN STATUS.
