SECTION 15820

AIR MONITORING STATION

Specifier Notes:  This section covers Ruskin Manufacturing air monitoring station with an outside air ventilation controller for indoor air quality, Model AMS50.  Consult Ruskin for assistance in editing this section for specific applications.	

PART 1	GENERAL

1.1	SECTION INCLUDES

A.	Air monitoring station with an outside air ventilation controller for indoor air quality.

1.2	RELATED SECTIONS

Specifier Notes:  Edit the following list as required for the project.  List other sections with work directly related to the air monitoring station.	

A.	Section 15810 - Ducts.

B.	Section 15900 - HVAC Instrumentation and Controls.

C.	Section 15900 - Damper Actuators.

1.3	REFERENCES

A.	AMCA 611 - Certified Ratings Program - Airflow Measurement Performance.

B.	ASHRAE 62 - Ventilation for Acceptable Indoor Air Quality.

1.4	SYSTEM DESCRIPTION

A.	Air monitoring station incorporates a low leakage control damper with air monitoring blades and air straightener section in one assembly.

B.	Control damper is designed for modulating operation and utilizes standard blade and jamb seals for low leakage.

C.	Strategically placed airflow sensing blades measure airstream velocity.

D.	Air tubing and piping connections connect sensing blades to controller.

E.	Using velocity information provided from sensing blades, controller will calculate a cfm value.  This value will then be compared to design cfm setpoint as determined by particular mode of operation of HVAC system.  In normal operation, this setpoint will correspond to minimum outside air ventilation required by system design to meet ASHRAE 62.

F.	Based on difference between actual cfm reading and desired setpoint, controller will interact with control damper actuator to position damper blades as necessary to ensure that actual outside air flow meets desired level.

1.5	SUBMITTALS

A.	Comply with requirements of Section 01330 - Submittal Procedures.

B.	Product Data:  Submit manufacturer's product data.
1.	Indicate materials, construction, dimensions, and installation details.
2.	Submit certification that air monitoring station is licensed to bear AMCA Certified Ratings Seal for Airflow Measurement Performance.
3.	Verify conformance to ASHRAE 62.

1.6	QUALITY ASSURANCE

A.	Air monitoring station shall be tested for differential pressure in accordance with AMCA 611 in an AMCA registered laboratory.

B.	Air monitoring station shall bear AMCA Certified Ratings Seal for Airflow Measurement Performance.

1.7	DELIVERY, STORAGE, AND HANDLING

A.	Delivery:  Deliver materials to site in manufacturer's original, unopened containers and packaging, with labels clearly indicating manufacturer and material.

B.	Storage:  Store materials in a dry area indoors, protected from damage and in accordance with manufacturer's instructions.

C.	Handling:  Handle and lift materials in accordance with manufacturer's instructions.  Protect materials and finishes during handling and installation to prevent damage.
