NOTES:

EXISTING AHU (EX)1-AHU-1 TO REMAIN A CONSTANT VOLUME AHU AND RA TO BE

ADDED AND CONTROL SYSTEM TO BE COMMISSIONED.

CONTROLS EQUIPMENT SHOWN ON NEW RA AND MIXED AIR TEMPERATURE ARE NEW.

1. GENERAL

a. 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, SHALL BE

FULLY CLOSED. WHEN THE UNIT IS "ON" D-1, SD-1 AND D-2 SHALL BE FULLY OPEN.

2. TEMPERATURE CONTROL

a. SUPPLY AIR TEMPERATURE, SENSED BY TT-1, SHALL BE MAINTAINED AT SETPOINT VIA DIGITAL CONTROL PANEL BY MODULATING V-1 OR V-2 IN SEQUENCE.

3. AIR FLOW CONTROL

a. THE SUPPLY AIR FLOW SHALL BE CONTROLLED BY THE DIGITAL CONTROL PANEL MAINTAINING THE SUPPLY FAN CONTANT 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.

b. 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.

c. 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.

4. HUMIDITY CONTROL

a. 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. DISABLE (EX)HUMIDIFIER WHEN THE DIGITAL CONTROL PANEL IS

CALLING FOR HUMIDITY, ENABLE (EX)HUMIDIFIER AND V-3 SHALL REMAIN OPEN.

b. RETURN AIR HUMIDITY SHALL BE MAINTAINED AT SETPOINT OF 35% RH (ADJ) VIA DIGITAL CONTROL PANEL BY MODULATING HUMIDIFIER 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. (EX)HUMIDIFIER SHALL BE INTERLOCKED WITH A TEMPERATURE SWITCH TO KEEP THE HUMIDIFIER OFF UNTIL CONDENSATE

TEMPERATURE APPROACHES STEAM TEMPERATURE.

5. FREEZE PROTECTION

a. 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.

6. AUTOMATIC SHUTDOWN/RESTART

a. WHEN SMOKE IS DETECTED BY DUCT SMOKE DETECTOR, SD, THE SUPPLY FANS SHALL SHUT "OFF" AND AN ALARM SIGNAL SHALL BE TRANSMITTED TO THE FIRE ALARM SYSTEM. ALL SMOKE DAMPERS IN THE SUPPLY SHALL CLOSE.

b. EXHAUST FANS SERVING AREA OF THE SUPPLY FAN SHALL CONTINUE TO RUN. SUPPLY AND RETURN FANS SHALL RESTART AND SMOKE DAMPER SHALL OPEN WHEN FIRE ALARM CIRCUIT IS RESET.

7. EMERGENCY CONSTANT SPEED OPERATION

a. UPON FAILURE OF THE VSMC, THE SUPPLY FAN SHALL BE STARTED/STOPPED MANUALLY AT THE DIGITAL CONTROL PANEL OR THE BAS THROUGH THE BY-PASS STARTER. FANS SHALL THEN BE OPERATED AT CONSTANT SPEED.

TEST AND BALANCING AND COMMISSIONING OF EXISTING GI LAB. AHU-1:

1. THE CONTRACTOR SHALL PROVIDE TEST AND BALANCING SERVICES FOR THE EXISTING GI LAB AHU-1.

2. COMMISSION SERVICES SHALL ALSO INCLUDE COMMISSIONING OF EXISTING GI LAB AHU-1. THE COMMISSIONING PROCESS, WHICH THE CONTRACTOR IS

RESPONSIBLE TO EXECUTE, IS DEFINED IN SECTION 01 91 00 GENERAL COMMISSIONING REQUIREMENTS. A COMMISSIONING AGENT (CXA) APPOINTED BY THE VA

WILL MANAGE THE COMMISSIONING PROCESS.

3. COMMISSIONING OF A SYSTEM OR SYSTEMS SPECIFIED IN DIVISION 23 IS PART OF THE CONSTRUCTION PROCESS. DOCUMENTATION AND TESTING OF THESE SYSTEMS, AS WELL AS TRAINING OF THE VA’S OPERATION AND MAINTENANCE PERSONNEL IN ACCORDANCE WITH THE REQUIREMENTS OF SECTION 01 91 00 AND OF DIVISION 23, IS REQUIRED IN COOPERATION WITH THE VA AND THE COMMISSIONING AGENT.

NOTE:

EXISTING SCHEDULE IS FROM ORIGINAL AHU INSTALLATION AND IS BASED ON THE BEST

INFORMATION AVAILABLE.
