Measurement probe FloxactTM INSTALLATION INSTRUCTIONS INTRODUCTION To measure air flow accurately in a ventilation duct, use a special FloXactTM measurement probe together with a DPT-Flow transmitter. WARNING · READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO INSTALL, OPERATE OR SERVICE THIS DEVICE. · Failure to observe safety information and comply with instructions can result in PERSONAL INJURY, DEATH AND/OR PROPERTY DAMAGE. · To avoid electrical shock or damage to equipment, disconnect power before installing or servicing and use only wiring with insulation rated for full device operating voltage. · To avoid potential fire and/or explosion do not use in potentially flammable or explosive atmospheres. · Retain these instructions for future reference. · This product, when installed, will be part of an engineered system whose specifications and performance characteristics are not designed or controlled by HK Instruments. Review applications and national and local codes to assure that the installation will be functional and safe. Use only experienced and knowledgeable technicians to install this device. STEp 1: SELECTING THE CORRECT FLOXACTTM PROBE There are two FloXactTM models available: R model for round ducts and L for rectangular ducts. In order to achieve the best accuracy, it is recommended to use two FloXactTM-L probes if the height of a rectangular duct is more than 350 mm, three probes if the duct size is 700 mm or more, and four probes if the duct size is 1000 mm or more. FloXactTM-R models available: 100, 125, 160, 200, 250, 315, 400 and 450 and all other standard round duct sizes up to 1200 mm. FloXactTM-L models available: 250, 300... 1200 (50 mm steps) Length of the probe (L) is defined by the width (W) of the duct. (See step 5). Other sizes are available on request. Example: for a 160 mm round duct, choose FloXact-R160 probe, and for a 500x400 mm rectangular duct, choose two FloXact-L500 probes. step 2: SELECTING THE CORRECT DPT-FLOW MODEL It is recommended to use DPT-Flow-1000-AZ-D model with FloXactTM probes because dynamic duct pressure is rarely over 500 Pa. Typical pressure range in a ventilation duct is 0...250 Pa. The measurement range of DPT-Flow-1000-AZ-D is 0...1000 Pa.

Figure 1 - Mounting MOUNTING THE PROBE continued 6) Connect the tubes from the FloXactTM pressure inlets to the inlet in the pressure transmitter. Connect the plus tube to the plus inlet and the minus tube to the minus inlet. · If more than one FloXactTM probes used, use t-hose connector to connect tubes from separate probes. Figure 4 4) Check that air flow direction in the duct corresponds with the indication on the FloXactTM probe. Figure 2 - Air flow direction FloXactTM-L mounting 5) Attach the probe(s) into the duct with two screws. Figure 3 - Attaching with screws FloXactTM-R mounting · For round ducts, we recommend installing the FloXactTM probe horizontally in the duct. FloXactTM-R mounting with two probes. When do I need more than one probe? Check step 1. · For non standard applications, please contact your nearest distributor or the factory.

For the FloXactTM-L KV value must be determined by dimensions (width and height) of the duct. Figure 6 - Rectangular duct The air volume can be determined with the following formula: Q = K V x Pfs Q = air volume in l/s KV = KV value in l/s/Pa Pfs = pressure difference measured by the FloXact stick in Pa The table is for air with 1.20 kg/m3 density (20 °C, 50 % rH and 1013 mbar). The K-value for different densities is deter- mined with the following formula: Corrected K-value = Kv * (/1.20) K-factor = 921xBx(H-0,025n) l/s B= duct width in meter H = duct height in meter n = number of FloXact used For intermediate sizes, contact our office.

Decommissioned devices should be taken to a recycling site that specializes in electronic waste. WARRANTY POLICY The seller is obligated to provide a warranty of five years for the delivered goods regarding material and manufacturing. The warranty period is considered to start on the delivery date of the product. If a defect in raw materials or a production flaw is found, the seller is obligated, when the product is sent to the seller without delay or before expiration of the warranty, to amend the mistake at his/her discretion either by repairing the defective product or by delivering free of charge to the buyer a new flawless product and sending it to the buyer. Delivery costs for the repair under warranty will be paid by the buyer and the return costs by the seller. The warranty does not comprise damages caused by accident, lightning, flood or other natural phenomenon, normal wear and tear, improper or careless handling, abnormal use, overloading, improper storage, incorrect care or reconstruction, or changes and installation work not done by the seller. The selection of materials for devices prone to corrosion is the buyer's responsibility, unless otherwise is legally agreed upon. Should the manufacturer alter the structure of the device, the seller is not obligated to make comparable changes to devices already purchased. Appealing for warranty requires that the buyer has correctly fulfilled his/her duties arisen from the delivery and stated in the contract.
