CAUTION: Servicing Disconnect main power before any servicing.During and following operation of the humidifier, the steam and components incontact with the steam such as the blower pack, steam lines, steam distributors,and condensate lines can become hot and can burn if touched.Nortec does not accept any liability for installations of humidity equipmentinstalled by unqualified personnel or the use of parts/components/equipmentthat are not authorized or approved by Nortec.CAUTION: Plumbing Plumbing to be performed by a licensed plumber.Drain water from humidifier can be very hot. Do not drain to public sink.All plumbing work should be done according to local plumbing code.CAUTION: Installation Do not mount on hot surfaces.Do not mount in area where freezing can occur. Do not mount on vibrating surface.Do not mount on floor.The RH2 produces steam at atmospheric pressure no devices which could blocksteam output should be connected to the steam outlet.Steam lines must be installed so that no restriction can produce backpressure inthe humidifier. 1 SAM-e Installation

IntroductionReceiving and Unpacking EquipmentCheck packing slip to ensure ALL material has been delivered. Each humidifier may be shippedin more than one box.All material shortages are to be reported to NORTEC within 48 hours from receipt of goods.NORTEC assumes no responsibility for any material shortages beyond this period.Inspect boxes for damage and note on shipping waybill accordingly.After unpacking, inspect equipment for damage. If damage is found, notify the shipper promptly.All NORTEC products are shipped on an F.O.B. factory basis. Any and all damage, breakage, or lossclaims are to be made to the shipping company.Location of Humidifier’s Manifold in an Air Conditioning SystemAlthough SAM-e distribution systems are designed to provide drip-less humidification, several operatingfactors related to steam supply may result in excess moisture or water collecting insteam-tube pipe with the potential for water damage. To ensure protection against water damage, bestpractice includes either a sealed section of duct or, preferably a drip-pan with drain installed underneatheach unit. In addition, to facilitate maintenance checks and inspections, an inspection cover, inspectionglass or service opening should be installed downstream.For more information, see SAM-e Engineering Manual [1503529-X].NotesAbsorption distance: the distance between the SAM-e and the first obstruction (coil, elbow, damper, etc.)that steam may encounter. Traces of steam may pass the obstruction, but will not condense, leavingobstructions dry. If any of the duct or air-handling unit (AHU) conditions are changed between designand installation, calculated absorption distance may change. It is advisable to re-calculate absorptiondistance to ensure that SAM-e operates as intended. If changes are required, please contact factory forassistance.SAM-e Installation 2

1Fasten support brackets to header using 5/16” washers and 5/16” nylon lock-nuts.2Place header on duct floor and drill 4 x 1/2” (12.7 mm) holes through floor.Secure header to floor using fasteners (by others).Use caulking to seal holes in ductwork.9 SAM-e Installation

3Insert tube into insertion stop washer and then into grommet.Wetting grommet with water will make assembly easier.Ensure nozzles face the sides of the duct (perpendicular to air flow).4Assemble remaining tubes in same way.SAM-e Installation 10
