PART 2 - PRODUCTS

2.1		SHORT ABSORPTION MANIFOLD

A.	Short Absorption Manifold designed for atmospheric steam humidifiers or pressurized steam from a boiler, to directly inject the steam into ducted air for humidification.
1.	Absorption distance characteristic shall prevent water accumulation on any induct surfaces beyond ___in (___mm) downstream of the steam dispersion panel. (Refer to distance calculated in H.E.L.P. Software).
2.	Steam dispersion panel consisting of a (one) horizontal stainless steel header supplying steam to a bank of closely spaced 3” (7.6 cm) OR 6” (15.2 cm) OR 9” (22.9 cm) OR 12” (30.5 cm) vertical tubes (3” (7.6 cm) OR 6” (15.2 cm) for mini SAM-e), as necessary to meet absorption distance requirements, and to reduce condensation losses.
3.	Single horizontal stainless steel header to provide steam to vertical distributor tubes and to reduce condensation losses. Dual header systems creating unnecessary condensation, or systems needing to be installed on a partition or requiring blank off plates are not acceptable.
4.	Header design is primarily round tube to minimize pressure drop. Square headers are not acceptable. (Full-size SAM-e only).
5.	Slim profile rectangular profile header design minimizes pressure drop. (Mini SAM-e only).
6.	Steam inlet and condensate return located on the same side and at the bottom of the header to allow single point entry and floor mounting.
7.	Headers are 304 stainless steel construction.
8.	Vertical stainless steel distribution tubes to promote condensate evacuation. Horizontal distributor tubes are not accepted.
9.	Distribution tubes shall include threaded standoffs for trouble free attachment to factory- supplied support bracket.
10.	All tubes are available in either 409 or 304 stainless steel construction.
11.	Stainless steel nozzle inserts ensure condensate free steam is discharged from the center of the distribution tubes. Systems without nozzle inserts, or other than stainless steel, are not acceptable.
12.	Stainless steel nozzle inserts shall have metered orifices, sized to provide even distribution of the discharged steam, spaced for optimum steam absorption.
13.	Tubes and headers shall accommodate factory installation or field retrofit of optional insulation for increased energy efficiency.

B.	Options
1.	Tube and header insulation constructed from 304 stainless steel shielding for increased energy efficiency and reduced airstream heat gain. Stainless steel shields to be isolated from distributor using plenum rated synthetic foam strips. Insulation to provide air-gap to minimize conduction and convection, as well provide reflective surface to minimize radiating heat transfer. (Patent Pending).  Uninsulated headers, or simple foam insulation not accepted.
2.	Adjustable mounting frame available for quick and easy installation. (Does not apply for mini SAM-e).

C.	Standard of acceptance: Nortec SAM-e.

PART 3 - EXECUTION

3.1	 	EXAMINATION

A.	Examine ducts, air-handling units, and conditions for compliance with requirements for installation tolerances and other conditions affecting performance.

B.	Examine roughing-in for piping systems to verify actual locations of piping connections before humidifier installation.

C.	Proceed with installation only after unsatisfactory conditions have been corrected.

3.2 	INSTALLATION

A.	Install humidifiers and steam dispersion panels per manufacturers' instructions.

B.	Seal humidifier dispersion-tube duct penetrations with flange.

3.3		TESTING

A.	System verification testing is part of the commissioning process. Verification testing shall be performed by the Contractor and witnessed and documented by the Commissioning Authority.  Refer to section 01810, Commissioning, for system verification tests and commissioning requirements.

XXXXX  OR  XXXXX

A.	Manufacturer's Field Service:  Engage a factory-authorized service representative to inspect field-assembled components and equipment installation, including piping and electrical connections.  Report results in writing.

1.	Leak Test:  After installation, charge system and test for leaks.  Repair leaks and retest until no leaks exist.
2.	Operational Test:  After electrical circuitry has been energized, start units to confirm proper unit operation.  Remove malfunctioning units, replace with new units, and retest.
3.	Test and adjust controls and safeties.  Replace damaged and malfunctioning controls and equipment.

3.4	TRAINING

A.	Training of the Owner’s operation and maintenance personnel is required in cooperation with the Commissioning Authority.  Provide competent, factory-authorized personnel to provide instruction to operation and maintenance personnel concerning the location, operation, and troubleshooting of the installed systems.  The instruction shall be scheduled in coordination with the Commissioning Authority after submission and approval of formal training plans.
