(Manufacturer) warrants to the Customer that if any part(s). of the Manufacturer's equipment proves to be defective in materials or workmanship within the earlier of 18 months of the date of shipment or 12 months of the date of start- up, such defective parts will be repaired or replaced free of charge.

2 Inspection and repairs to products thought to be defective within the warranty period will be completed at the Manufacturer's facilities in Collegeville, PA. Products on which warranty repairs are required shall be shipped freight prepaid to the Manufacturer. The product(s) will be returned freight prepaid and allowed if it is determined by the manufacturer that the part(s) failed due to defective materials or workmanship. This warranty does not cover consumable items, batteries, or wear items subject to periodic replacement including lamps and fuses. Gas sensors carry a 12 months from date of shipment warranty and are subject to inspection for evidence of misuse, abuse, alteration, improper storage, or extended exposure to excessive gas concentrations.

3 Should inspection indicate that sensors have failed due to any of the above, the warranty shall not apply. The Manufacturer assumes no liability for consequential damages of any kind, and the buyer by acceptance of this equipment will assume all liability for the consequences of its use or misuse by the Customer, his employees, or others. A defect within the meaning of this warranty is any part of any piece of a Manufacturer's product which shall, when such part is capable of being renewed, repaired, or replaced, operate to condemn such piece of equipment. This warranty is in lieu of all other warranties ( including without limiting the generality of the foregoing warranties of merchantability and fitness for a particular purpose), guarantees, obligations or liabilities expressed or implied by the Manufacturer or its representatives and by statute or rule of law.

4 This warranty is void if the Manufacturer's product(s) has been subject to misuse or abuse, or has not been operated or stored in accordance with instructions, or if the serial number has been removed.

Part 1 - Introduction General The Model q46n is an on-line monitoring system designed for the continuous measurement of dissolved ammonia in aqueous solution. The full scale display range of the system is ppm, but the chemistry used in the monitor limits the reliable range of operation to PPM.

9 The sensing system will operate on water streams with temperatures ranging from 5 to 40 C. The q46n . Dissolved Ammonia Measurement System is well suited for potable water systems and wastewater treatment effluents. The q46n Dissolved Ammonia Measurement System uses reaction chemistry that converts ammonia in solution to a stable monochloramine compound equivalent in concentration to the original ammonia level. The chloramine concentration is then measured with a unique amperometric sensor that responds linearly to chloramines, while eliminating interference from excess free chlorine in solution. Sample connections are made to an inlet filtration system attached to the right side of the chemistry system.

10 The inlet filter housing contains two FNPT. ports, one on the bottom for inlet and one on the side for outlet. An adapter for ID tubing is supplied for the inlet and a right angle adapter for 3/8 ID drain tubing is supplied for the outlet. These fittings can be replaced by customer supplied fittings if preferred. The outlet size should always be larger than the inlet to avoid pressurizing the filter system. The q46n Ammonia Monitor consists of two separate parts, a wall mounted electronic unit and a separate chemistry system. Because of the special wiring required for communication options available on the Q46, the single box system available in the q46n Model is not available.
